A safety instruction designed in this way indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING

Such a safety instruction indicates a potentially hazardous situation which, if not avoided, may result in serious injury or even death. CAUTION A safety instruction designed in this way indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. NOTICE A safety notice designed in this way indicates a potentially hazardous situation which, if not avoided, may result in property damage. Irrespective of all safety regulations, your common sense and appropriate technical suitability/training are and will remain the most important safety factor for error-free operation of the machine. Safe working primarily depends on you! 16 TRANSPORT WARNING

Damaged or insufficiently strong hoists and load slings can result in serious injury or even death. Before use, therefore, check hoists and load slings for adequate load- bearing capacity and perfect condition. Secure the loads carefully. Never stand under suspended loads!

To ensure proper transport, observe the instructions and information on the transport packaging regarding centre of gravity, attachment points, weight, means of transport to be used and the prescribed transport position, etc. Transport the machine in its packaging to the place of installation. To manoeuvre the machine in the packaging, a pallet truck or forklift truck with the appropriate lifting force can be used, for example. Ensure that the selected lifting equipment (crane, forklift, pallet truck, load sling, etc.) is in perfect condition. Lifting and transporting the machine may only be carried out by qualified personnel with appropriate training for the lifting equipment used. NOTICE

Avoid using sling chains as there is a risk of damaging the feed screw or the lead screw. Make sure that the lead screw, feed screw and selector shaft of the lathe are not touched by the lifting slings when lifting. Never lift the machine by the spindle! To position the machine at the installation location, proceed as follows:ASSEMBLY

1. Prepare two sufficiently strong round

steel bars (length approx. 800 mm, Ø approx. 35 mm).

2. Guide the round steel bars through the

prepared holes (1) in the stand.

3. Attach a lifting sling to each of the four

ends of the two round steel bars.

4. Lift the machine with a suitable conveyor

(e.g. crane). Note: Before lifting, check that the tailstock is clamped. Ensure that the load stop is balanced. If necessary, change the position of the bed carriage and/or tailstock to obtain a balanced load stop. 17 ASSEMBLY

17.1 Preparatory activities

17.1.1 Checking delivery content

Always note visible transport damage on the delivery note and check the machine immediately after unpacking for transport damage or missing or damaged parts. Report any damage to the machine or missing parts immediately to your retailer or freight forwarder.

17.1.2 Cleaning and lubrication

Before you install and commission the machine at the intended location, carefully remove the anti-corrosion protection and grease residues. Under no circumstances should you use nitro thinner or other cleaning agents that could attack the machine's paint. Oil bare machine parts (e.g. machine bed, tailstock sleeve, feed spindle) with an acid-free lubricating oil.

17.1.3 Site requirements

Place the machine on a solid surface. A concrete floor is the best foundation for the machine. If necessary, use an underframe. The space required by the machine and the required load-bearing capacity of the subfloor result from the technical data (dimensions, weight) of your machine. When designing the working area around the machine, observe the local safety regulations. When dimensioning the required space,ASSEMBLY

take into account that the operation, maintenance and repair of the machine must be possible without restrictions at all times. The selected installation location must ensure a suitable connection to the electrical mains.

17.1.4 Anchorless assembly

NOTICE The use of machine feet (not supplied) facilitates levelling of the machine and reduces vibrations. After the machine has been brought into the desired position at the intended installation location, it must be levelled in the longitudinal and transverse axes using the pressure screws.

1. Place the adjusting disks (3) under the machine base.

2. Mount the adjusting screws (1).

3. Align the lathe with a precision balance (accuracy: 0.02

mm over 1000 mm length).

4. After levelling, secure the set screws with lock nuts (2) to

prevent them from turning.

5. Check the alignment after a few days of use of the

machine and, if necessary, adjust it according to the following instructions

17.1.5 Anchored assembly

NOTICE Insufficient rigidity of the substrate leads to the superposition of vibrations between the machine and the substrate (natural frequency of components). If the stiffness of the overall system is insufficient, critical speeds are reached quickly, which leads to poor turning results. Use the anchored assembly to achieve a rigid connection with the ground. This reduces the vibration potential. The anchored assembly is always useful when turning knives or turning tools with HM alloy are to be used and/or large parts up to the maximum capacity of the machine are to be machined.

1. Place the machine on the anchor bolts

(MF) adjusting disks (3).

2. Then align the machine and tighten the

3. Check the alignment of the machine

again after having tightened the counter nuts (2).

The machine is pre-assembled, the parts removed for transport must be assembled according to the following instructions and the connection to mains have to be made. Mounting the DRO Mount the bracket for the digital position indicator (DRO) above the main switch with the 2 screws. Fasten the bracket on the cross support. Fasten the 2 brackets to the DRO with 4 Allen screws and 4 washer.ASSEMBLY

Fasten to the cross support with Allen screw, washers and nut.

Connect the connecting cables to the DRO. Determine the correct axis by turning the respective handwheels and change connections if necessary. When all cables are in the correct position, secure plugs with the screws.

Mounting the tool post guard Place the tool post guard on the bracket and fix it with the Allen screw.

After installation and commissioning, it is recommended to check the alignment and levelling of the machine before using it for the first time. In order to ensure working accuracy, the alignment and levelling should be repeated at regular intervals. To level the machine, use a precision spirit level (according to DIN 877) with an accuracy of 0.02 mm to 1000 mm. This allows the horizontal position of the machine axis to be checked with sufficient accuracy in both the longitudinal and transverse directions. For anchored installation: Do not tighten the anchor bolt nuts carefully and evenly until three to four days after the cement has cured. Repeat the horizontal check a few days after initial start-up and every six months thereafter.

17.2.2 Checking the fit of the jaw chuck

Do not use cast iron chucks. Use ductile iron chucks only. Before disassembling the jaw chuck, place a stable board or chuck cradle under the spindle to protect the precision-ground surfaces. NOTICE When mounting a chuck or face plate, first make sure that the cam-lock studs are properly fixed. Otherwise, the chuck/face plate may never be removed again later because the cam-lock studs have become twisted.ASSEMBLY

Carefully disassemble the jaw chuck. To do this, loosen the cam-locks by turning them clockwise (approx. one third of a turn) using the clamping key supplied and carefully remove the jaw chuck. Check the cam-lock studs. Ensure that they are not damaged or broken during transport. Clean all parts thoroughly. Also clean the spindle and the cam-locks. Lightly oil the spindle, cam-locks, camlock studs and chuck body with a suitable machine oil.

Then lift the jaw chuck up to the spindle nose and press on the spindle. Tighten the cam-lock studs by turning the cam-locks counterclockwise. After tightening, the cam-lock line should be located between the two V-marks - see illustration on the left. If a cam is not within this mark, remove the chuck or face plate and adjust the height of the cam-lock studs - see the following illustration.

The cam-lock stud is correctly adjusted when the mark (C) carved into the stud is flush with the back of the chuck. If the cam-lock line is outside the V markings, adjust the height of the relevant cam-lock stud. To do this, first loosen the retaining screw (B), adjust the cam-lock stud by turning it in/out one full turn at a time and then tighten the retaining screw firmly again.

If the chuck (clamping device) is correctly fastened, a reference mark should be attached to the spindle and clamping device so that the clamping device can always be released and remounted in the same position to ensure optimum concentricity. Do not change chucks or face plates between lathes without checking for correct cam-locking.

17.2.3 Mounting workpiece holders

WARNING The max. spindlespeed of the machine must be lower than the max. permissible speed of the used workpiece holder. Centring tip

1. Clean the inner taper of the spindle holder.

2. Clean the morse taper and the taper of the centering tip.

3. Press the centring tip with the morse taper into the inner taper

1. Check the fitting surfaces on the turning spindle holder and on the workpiece carrier to be

mounted for cleanliness and undamaged holding surfaces.

2. Check that all clamping bolts in the spindle holder are in the open position.

3. Lift the face plate onto the turning spindle holder.

4. Fasten the clamping bolts as described in the section "Checking the fit of the jaw chuck".

4-jaw chuck NOTICE The shoulder for centering the four-jaw chuck on the mounting flange was not finished for reasons of concentricity. The mounting flange must be adapted to the

1. Check the fitting surfaces on the turning spindle mounting and on the flange to be

mounted for the four-jaw chuck for cleanliness and undamaged mounting surfaces.

2. Check that all the clamping bolts in the spindle holder are in the open position.

3. Lift the flange onto the spindle holder.

4. Fasten the clamping bolts as described in the section "Checking the fit of the jaw chuck".

Adjust the centering shoulder on the locating flange to the four-jaw chuck in axial and radial run- out by turning.

17.2.4 Adjusting the headstock

The headstock (1) was aligned at the factory. If, contrary to expectations, an adjustment is required, proceed as follows: Clamp one end of a steel tube 150 mm long and 50 mm in diameter into the headstock chuck. The other end runs free. Now remove a thin layer with a sharp turning chisel. The values measured with the dial gauge or calliper at points A and B must match. If this is not the case, loosen the four headstock fixing screws (J) to correct the difference (two are below the headstock) and readjust using the adjusting screw (K). Then tighten the fixing screws again and repeat the rotation, measurement and adjustment until the measured values match and the machine runs smoothly.

17.2.5 Adjusting the tailstock

To adjust the tailstock, clamp a ground steel tube 305 mm long between the headstock and tailstock tips (see illustration above). Now place a dial gauge on the top slide and pull it along the workpiece axis below the workpiece. If the dial gauge shows different values, loosen the tailstock clamping lever (A) and readjust using the two set screws. Repeat this procedure until both points are exactly aligned.

17.2.6 Adjusting the sliding guides

The sliding guides of the cross slide and top slide are equipped with bevelled guide rail adjusting screws (see illustration on the left), which can be used to eliminate any play that may occur there over time. Ensure that the slideways are thoroughly cleaned before adjustment. Then adjust the guide pads by loosening the rear guide pad adjusting screw a little while tightening the front one a little. Ensure that smooth running is guaranteed over the entire sliding guide section. Too tight an adjustment will result in increased wear and heavy, jerky running.

17.2.7 Visual inspection

NOTICE The machine is delivered with running-in oil! This oil must be changed after the running-in period (approx. 100 operating hours). Failure to do so may cause serious damage to the machine. For running operation, use a viscous oil with viscosity ISO 220 (e.g. GOE5L) or a comparable SAE140 oil! NOTICE

Lubricants are toxic and must not be released into the environment! Always follow the manufacturer's instructions and, if necessary, contact your local authority for information on proper disposal. Check the lubrication of the following parts and top up with suitable oil if necessary before working on the machine:

Headstock The bearing of the headstock is in an oil bath. Make sure that the oil level always reaches the mark of the sight glass (1). Check the oil level regularly. First oil change after 100 operating hours, then change the oil once a year or after 1000 operating hours. See Maintenance Feed gear

Make sure that the oil level always reaches the mark of the sight glass (2). First oil change after 100 operating hours, then change the oil once a year or after 1000 operating hours. See MaintenanceASSEMBLY

Check the oil level regularly using the oil sight glass (3) on the front. First oil change after 100 operating hours, then change the oil once a year or after 1000 operating hours. See Maintenance Other oiling points Lubrication points can be found on the drive shaft, on the lead screw and feed rod, on the slides, on the handwheels and on the tailstock. Lubricate these points regularly with a grease gun. See Maintenance.

17.2.8 Filling with coolant

Coolants are toxic and must not be released into the environment! Follow the manufacturer's instructions and contact your local authority for information on proper disposal if necessary. Operating the coolant pump without coolant in the tank can permanently damage the pump. High temperatures occur at the cutting edge of the tool due to the frictional heat. The tool should therefore be cooled during turning. Cooling with a suitable coolant will improve the work result and prolong the tool life. Therefore, fill with coolant. Use a water-soluble, environmentally compatible emulsion as coolant, which is available from specialty retailers (e.g. KSM5L). The coolant tank is located in the right foot of the machine, below the tailstock. Loose the 4 Allen screws and remove the cover. Check the coolant at regular intervals. Make sure that:

• there is sufficient coolant available,

• the chip mirror in the first chamber is not too high and

• the coolant is not rancid or contaminated. Apply coolant

1. Make sure that the coolant tank is properly maintained and filled.

2. Position the coolant nozzle as required for your operation.

3. Use the switch on the control panel to turn the coolant pump on or off.

4. Use the flow valve to regulate the flow of coolant.

17.2.9 Function test

18.5.6 Thread pitch table / longitudinal feed for imperial threads

Imperial threads range from 2 to 28 TPI, 30 steps are available.OPERATION

18.5.7 Thread dial indicator (for resumption of the pitch)

Do not engage the lock nut if the lead screw rotates at more than 200 revolutions per minute or if the carriage lock is locked, otherwise damage may be caused to the bearings or the shear pin of the spindle may break!

The thread dial indicator (1) can also be used for cutting metric threads. The thread dial indicator (to resume the pitch) is located on the right of the apron. The thread dial indicator has an important function. It indicates the correct moment to engage the " shift lever tapping (lock nut)” (2), so that the tool takes up the same turn again at each step. On the lower end of the thread dial indicator shaft there are several gear wheels with different numbers of teeth to be able to turn metric threads with different thread pitches. The vertical position of the thread dial indicator is changed as required so that the gear selected for the desired thread pitch engages with the lead screw.

On the dial of the thread gauge there are the numbered lines 1, 3, 5 and 7. In between there are lines without numbering, so called half lines. When the lead screw is engaged, the dial rotates. There is only one line mark (fixed line) on the housing of the thread dial indicator. The table on the side of the gearbox housing (see illustration on the left) shows the pitch, the selection and the coupling sequence of the marks on the rotating dial with the fixed mark. The numbers in the line "→" refer to the numbering of the graduation marks on the thread dial indicator. For threading, engage the lock nut at the height of the corresponding number indicated in the table.OPERATION

The main function of the tool post is to fix the tool. If necessary, the tool post can also hold more than one tool (maximum 4). When inserting the tool, make sure that the cutting head of the tool points in the direction of the rotation axis of the workpiece. Tool change CAUTION Before any manual tool change, stop the spindles, wait for all tools to come to a standstill and secure the machine against unintentional restarting before changing the tools!

Clamp the turning tool into the tool post (L). The turning tool must be clamped as short and tightly as possible in order to be able to absorb the cutting force occurring during chip formation well and reliably. Also ensure that the turning tool is clamped at a right angle to the axis of rotation (see illustration on the left). When clamping at an angle, the turning tool can be pulled into the workpiece. Align the turning tool in height. Use the tailstock with centering point to determine the required height. If necessary, place steel supports under the lathe tool to obtain the required height.

The cutting edge of the turning tool must be set exactly to centre height during facing so that the face is free of studs. Facing produces flat surfaces perpendicular to the workpiece axis of rotation. A distinction is made between transverse face turning, transverse cut-off turning and longitudinal face turning.

If the tool post must be turned, open the clamping lever by turning it counterclockwise. Turn the tool post to the desired position and then tighten it again by turning the clamping lever clockwise.

18.7 Mounting steady or follow rests

Use steady or follow rests to support long turned parts if the cutting force of the turning tool is likely to cause the turned part to deflect.OPERATION

The tailstock serves as a counter bearing when turning between the centres as well as for holding drilling, countersinking and reaming tools. It is guided on the cheeks of the machine bed and can be clamped at any point by a clamping lever (2). The tailstock is secured in the machine bed (cast bed) with an end position stop screw (1) to prevent the tailstock from sliding out unintentionally (see picture on the left). The tailstock spindle sleeve (1) can be moved by a threaded spindle and a handwheel (3) and can be clamped with a clamping lever (2). An inner taper in the quill accommodates the centering point, a drill chuck or tools with a tapered shank.

• Clamp your required tool into the tailstock sleeve.

• Use the scale on the sleeve for adjustment and/or readjustment.

• Clamp the sleeve with the clamping lever.

• Use the handwheel to retract and extend the tailstock sleeve.

18.8.1 Tailstock laterally offset

The transverse displacement of the tailstock is necessary, for example, when turning long, conical bodies. Loosen the tailstock clamping lever (1) and the adjusting screws (2) on the left and right of the tailstock. The desired transverse offset can be set with the help of the scale on the back of the tailstock. Finally retighten adjusting screws and clamping lever.

The turning diameter can be increased by removing the gap (1). Max. turning diameter without gap and length of the bed gap (2) can be found in the technical data. The max. turning length depends on the used workpiece holder.

• Place the longitudinal stop (if available) first on the right side of the machine bed (5).

• First loosen the fixing screws (3) and then pull out the locating pins (4).

18.10 General working instructions

Do not clamp workpieces that exceed the permissible clamping range of the workpiece holders, lathe chucks, etc. The clamping force of a lathe chuck is too low when the clamping range is exceeded. The clamping jaws can become loose. CAUTION

Regularly check the closed condition of the clamping bolts. The workpieces must be clamped securely and firmly on the machine before machining. The clamping force should be dimensioned in such a way that the workpiece can be securely gripped, but no damage or deformation of the workpiece occurs. Clamping the workpiece

1. Disconnect the machine from the mains.

2. Place a stable board or chuck cradle under the spindle to protect the precision-ground

3. Insert the chuck key into a scroll groove and turn it counterclockwise to open the jaws until

the workpiece lies flat on the clamping surface or evenly on the jaw steps or fits into the chuck hole and through the spindle hole.

4. Close the jaws until they make light contact with the workpiece.

5. Turn the chuck by hand to ensure that the workpiece is held evenly by all three jaws and

centred on the chuck. If the workpiece is not centred, release the jaws and realign the workpiece. Retighten the jaws and repeat step 5. When the workpiece is centred, fully tighten the jaws.

The 3-jaw chuck supplied with your machine is a scroll chuck, i.e. all three jaws move uniformly when the chuck key is turned. This jaw configuration is used to hold concentric workpieces that are centred with the same pressure from all three jaws. A set of reversible top jaws is also included to allow additional workpiece configurations.

Both sets of jaws can accommodate a workpiece on both the inside and outside - see illustration on the left. Regardless of how you configure the jaws, make sure the workpiece is firmly clamped in the jaw chuck.

WARNING Use the 4-jaw chuck only for low-speed turning operations. If the 4-jaw chuck is used at medium or high speed, unbalance will almost always occur and the operator or bystanders may be hit by an ejected workpiece.

The 4-jaw chuck has independently adjustable jaws. This means that non- cylindrical parts can be held for facing or drilling and brought into the spindle centre line. A further advantage is that the majority of workpieces can be positioned outside the spindle rotation axis, e.g. when a hole or step on an outer edge has to be cut into a workpiece. For optimum grip on non-cylindrically shaped workpieces, one or more jaws can also be rotated 180° to gain more clamping area.

WARNING When using the face plate, always use at least three independent clamping devices. Insufficient clamping can cause the workpiece to be thrown away during operation! The face plate has several slots for T-bolts which can accommodate clamping devices. Always use the face plate when you think that the 3- or 4-jaw chuck cannot hold the workpiece securely enough - see illustration on the left. Mounting the face plate

1. Disconnect the machine from the mains!

2. Insert a dead centre into the tailstock, push the tailstock up to the face plate and lock the

tailstock in position.

3. Place the workpiece on the face plate, turn the tailstock sleeve so that the dead centre

touches the workpiece.

4. Lock the quill when enough pressure is applied to hold the workpiece. Additional support

may be required depending on the workpiece.

5. Clamp the workpiece in at least three locations as evenly spaced as possible - see

6. Re-check all safety precautions and the backlash.

7. Slide the tailstock away from the workpiece and mount the required tailstock tools for

drilling or boring or position the chisel for turning.

18.10.4 Longitudinal turning

During facing, the planer tool is moved parallel to the axis of rotation. The feed is carried out either manually by turning the handwheel on the lathe slide or on the upper slide or by switching on the automatic feed. The infeed for the cutting depth is effected via the cross slide.OPERATION

18.10.5 Plain turning and recessing

When facing, the turning tool is moved at right angles to the axis of rotation. The feed is done manually with the handwheel of the facing slide. The feed of the cutting depth is effected by the top slide or the bed slide.

18.10.6 Fixing the lathe slide

The cutting force occurring during facing, grooving or cutting-off operations can cause the lathe slide to move. Therefore fasten lathe slide with the fixing screw.

18.10.7 Turning between tips

Workpieces that require a high concentricity are machined between the tips. A centre hole is drilled in both face turned faces of the workpiece. The turning heart is clamped onto the workpiece. The driving pin, which is screwed into the chuck flange, transmits the torque to the rotary heart. The fixed centering point is located in the centre hole of the workpiece on the spindle head side. The rotating center point is located in the centering hole of the workpiece on the tailstock side.

18.10.8 Turning short taper with the top slide

The short taper is turned by hand with the top slide. The upper slide is swivelled according to the desired angle. The infeed takes place with the cross slide:

1. Loosen the two clamping screws at the front and rear of the

2. Turn the upper slide to the desired position.

Threading or tapping requires good turning skills and sufficient experience from the operator. See the following example Example outside thread:

• The workpiece diameter must be turned to the diameter of the desired thread.

• The workpiece requires a chamfer at the beginning of the thread and an undercut at the end of the thread.

• The speed must be as low as possible.

• The thread chisel must correspond exactly to the thread form, be absolutely right-angled and clamped exactly to the turning centre.

• The engagement lever for thread cutting must remain closed during the entire thread cutting process. Excluded are the thread pitches which can be carried out with the tapping watch.

• The thread is produced in several cutting operations, so that the turning tool must be completely turned out of the thread (with the facing slide) at the end of a cutting operation.

• The return path is made with the clasp nut closed and the thread turning tool not engaged by actuating the "Shift lever Direction of rotation".

• Switch off the machine and reposition the chisel in small cutting depths with the cross slide.

• Before each run, adjust the upper slide by approx. 0.2 to 0.3 mm alternately to the left and right in order to free the thread. The thread chisel therefore only cuts on one thread flank in each pass. Do not cut free until shortly before reaching the full thread depth. 19 CLEANING NOTICE

Wrong cleaning agents can attack the varnish of the machine. Do not use solvents, nitro thinners, or other cleaning agents that could damage the machine's paint. Observe the information and instructions of the cleaning agent manufacturer! Prepare the surfaces and lubricate the bare machine parts with an acid-free lubricating oil. Regular cleaning is a prerequisite for the safe operation of the machine and its long service life. Therefore, clean the device after each use of chips and dirt particles. 20 MAINTENANCE WARNING

Danger due to electrical voltage! Handling the machine with the power supply up may result in serious injury or death. Always disconnect the machine from the power supply before servicing or maintenance work and secure it against unintentional restart!

The machine is low-maintenance and only a few parts have to be serviced. Nevertheless, any faults or defects which may affect the safety of the user must be rectified immediately!

• Before each start-up, make sure that the safety devices are in perfect condition and function properly.

20.1 Inspection and maintenance plan

The type and degree of machine wear depends to a large extent on the operating conditions. The following intervals apply when the machine is used within the specified limits: Interval Component What to do? Before start of work or after every maintenance or servicing Guideways oiling Change Gears lubricate lightly with grease Camlock Clamping Bolts Turning Spindle Adapter Check fastening Feed gear Apron Head Stock Visual inspection of the oil levels (via sight glass) Weekly Lead Screw Feed Shaft Tailstock Grease or fill all grease nipples and lubricators with machine oil. Top Slide Cross Slide Lathe Slide Grease or fill all grease nipples and lubricators with machine oil. Annually or after every 1000 operating hours Feed Gear Apron Head Stock Change oil As needed Guideways Adjust taper gib Head Stock Check V-belt and tighten if necessary Coolant Fill in

20.1.1 Adjusting the taper gibs

Too much play in the guideways can be reduced by adjusting the taper gibs. To adjust, turn the adjustment screw clockwise. This pushes the taper gibs backwards and reduces the clearance of the respective guideway.MAINTENANCE

20.1.2 Visual inspection of oil levels

Check oil levels of headstock (1), feed gear (2) and apron (3) before starting work or after every maintenance and repair. Oil level must reach at least to the middle or top mark.

20.1.3 Oil change headstock, feed gear and apron

Lubricants are toxic and must not be released into the environment. When changing, use suitable collecting containers with sufficient volume! Follow the manufacturer's instructions and, if necessary, contact your local authority for further information on proper disposal. Supply gear oil (recommended for ISO 12925-1 CKD, DIN51517 Part 3 CLP, US Steel 224, AGMA 9005- E02) with a viscosity of 220. Headstock (1) The bearing of the headstock is in an oil bath. Make sure that the oil level always reaches the mark of the sight glass. To change the oil remove the cover on the left side of the headstock, drain the oil by removing the drain plug (D). To refill the oil use the refill opening (F). Remount the cover. Check the oil level regularly. First oil change (running-in oil) after 100 operating hours, then change the oil once a year or after 1000 operating hours. Feed gear (2) Make sure that the oil level always reaches the mark of the sight glass. To change the oil remove the cover on the left side of the headstock, drain the oil by removing the drain plug (D). To refill the oil use the refill opening (F). Remount the cover. Check the oil level regularly. First oil change (running-in oil) after 100 operating hours, then change the oil once a year or after 1000 operating hours.MAINTENANCE

Apron (3) The oil must reach the mark in the oil sight glass. To change the oil, drain the oil by removing the drain plug (D). To refill the oil use the refill opening (F). Check the oil level regularly. First oil change (running-in oil) after 100 operating hours, then change the oil once a year or after 1000 operating hours.

20.1.4 Other lubrication points

Gear wheels Lubricate the gears with a heavy, non-spinning grease. Make sure that no grease gets onto belt pulleys or belts! Grease nipples and lubricators Lubricate or fill grease nipples or oilers on the lead screw and feed rod, on the tailstock as well as on the face and top slides with machine oil weekly.

20.1.5 Checking and cleaning the coolant system

Coolants are toxic and must not be released into the environment! Follow the manufacturer's instructions and contact your local authority for information on proper disposal if necessary. Checking the coolant system

1. Open the cover to the pump

chamber/coolant tank.

2. Check the coolant level in the tank.

The liquid should be about one centimetre below the top edge of the tank.

3. Check the level of the metal chips in the

first chamber. When the chips have reached 3⁄4 the height of the partition, remove the chips.

4. Check the quality of the coolant

according to the manufacturer's instructions and replace it as recommended.MAINTENANCE

Cleaning the coolant system

1. Empty any residual coolant still contained in the coolant nozzle into the drain container.

2. Lift the tank assembly out of its anchorage.

3. Remove all metal chips and remaining coolant and clean the tank.

4. Clean the suction strainer on the pump.

5. Reinstall the coolant tank in its original place.

6. Fill the tank with fresh coolant.

7. Properly mount the cover to the pump chamber.

Never replace V-belts individually but only as a complete set!

Open the screws on the covers and remove them. Loosen the adjusting nut (1) on the motor frame and decrease the V-belt Loosen the Allen screw (2) and remove the belt pulley. Change the V-belts Tighten the V-belts.

• The tension is correct when a single V-belt can only be pushed through a maximum of 5 mm with the thumb. Tighten the adjusting nuts again. Remount the cover (pay attention to the position switch!)

20.1.7 Replacing jaws

To replace the jaws, you must open the lathe chuck with the chuck key. In the fully open position, the jaws can then be removed one by one. The following must be observed when inserting the jaws:

• The threaded segments (2) of the jaws are graduated as shown in the figure.

• In addition, they are numbered (1) from 1 to 3 to indicate the actual pitch in the lathe chuck. Therefore, make sure to mount the jaws in the correct order:

1. Arrange the jaws as shown in the figure above and insert them clockwise into the slots of

the lathe chuck in this order.

2. Hold the jaws and clamp them with the chuck key.

3. Close the chuck completely and check that the jaws meet in the middle.

If a jaw does not fit properly, open the lathe chuck, press firmly on the jaw and turn the chuck key until the jaw is in the correct position. Check again that the jaws meet in the middle.STORAGE

20.1.8 Adjusting the overload clutch on the feed spindle

Never fully tighten the overload clutch set screw beyond the normal setting described in this procedure. Severe gear damage could result. The lathe is equipped with a spindle (1) overload clutch (3), which connects the drive hub to the feed spindle by means of a set of spring-loaded internal balls. This coupling helps to protect the lock case from overload and the machine from damage. The feed screw coupling is set at the factory, and if only readjusted when there is a problem, the coupling can be adjusted to the required position. The clutch slips, for example, if the path of the longitudinal or transverse slides is obstructed, if the tool collides with a workpiece shoulder, if the slide lock is actuated from the left when the feed selector lever is engaged, or if the cut is too deep. Adjusting the clutch: Disconnect the machine from the mains! If the clutch slips under normal working load and there is no problem with the feed system, the clutch spring pressure must be increased. To do this, tighten the two set screws (2) one eighth of a turn and check the clutch again for slippage. If, for any reason, the clutch becomes jammed or stuck and does not slip if it should, the clutch spring pressure must be reduced. To do this, loosen the two set screws (2) by one eighth of a turn and then check again for slippage. 21 STORAGE NOTICE

Improper storage can damage and destroy important components. Only store packed or unpacked parts under the intended environmental conditions!

When the machine is not in use, store it in a dry, frost-proof and lockable place to prevent the formation of rust on the one hand and to ensure that unauthorised persons and in particular children have no access to the machine on the other hand. 22 DISPOSAL Observe the national waste disposal regulations. Never dispose of the machine, machine components or equipment in residual waste. If necessary, contact your local authorities for information on the disposal options available. If you buy a new machine or an equivalent device from your specialist dealer, he is obliged in certain countries to dispose of your old machine properly.TROUBLESHOOTING

Danger due to electrical voltage! Manipulating the machine with the power supply up may result in serious injury or death. Before carrying out any troubleshooting work, always disconnect the machine from the power supply and secure it against unintentional recommissioning.

Many possible sources of error can be excluded in advance if the machine is properly connected to the mains. If you are unable to carry out necessary repairs properly and/or do not have the required training, always consult a specialist to solve the problem.
