Noise parameters according to EN 23746

The noise emission values determined according to EN 23746 for the sound power level or according to EN 31202 (correction factor k3 calculated according to Annex A.2 of EN 31204) for the sound level at the work place are based on the working conditions specified in ISO 7960 Annex A and are as follows:

Sound power level at the work place in dB

Idle running L_WA = 77.0 dB(A)

Processing L_WA = 87.0 dB(A)

Sound level at the work place in dB

Idle running L_pAeq = 69.0 dB(A)

Processing L_pAeq = 77.0 dB(A)

A measuring incertainty allowance K=4 dB applies for the specified emission values.

Specifications regarding the dust emission

The dust emission values that were measured according to the “Principles for the evaluation of the dust emission (concentration parameters) of wood working machines” of the Fachausschuss Holz (Expert committee wood) are below 2 mg/m ^3 . Thus, it can be assumed that the TRK limit value for wood dust applicable in the Federal Republic of Germany is permanently and reliably fallen short of when the machine is connected to a proper operational suction plant with an air speed of at least 20 m/s.

Please observe the load values of the material manufacturer depending on the materials to be processed or the material quality.

In these operating instructions we have marked the places that have to do with your safety with this sign: ⚠

⚠️ General Safety Rules

When using electric tools basic safety precautions should always be followed to reduce the risk of fire, electric shock and personal injury.

• Keep guards in place and in working order.
• Remove adjusting keys and wrenches. Form the habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.
• Keep the working area clean. Cluttered areas and benches invite accidents.
• Don't use in a dangerous environment. Don't use power tools in damp or wet locations, or expose them to rain. Keep work area well lighted.
• Keep children away. All visitors should be kept at a safe distance from the work area.

- Make your workshop kid proof. Lock your workshop. Tools not used should be kept in a dry place, inaccessible for children.

- Don't force the tool. It will do the job better and safer at the rate for which it was designed.

- Use the right tool. Don't force the tool or attachment to do a job for which is was not designed.

- Use proper extension cord. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in voltage resulting in loss of power and overheating.

- Wear proper clothing. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip shoes are recommended. Wear protective hair covering to contain long hair. Roll your sleeves up to above the elbows.

- Protect your eyes by safety goggles. Everyday eyeglasses offer only little protection. They are no safety glasses. Wear a face or dust mask when working in a dusty environment.

- Secure work. Use clamps or a vice to hold work, when practical. It is safer than using your hand, and it frees both hands to operate the tool.

- Don't overreach. Keep proper footing and balance at all times.

- Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow the instructions for lubricating, and changing accessories.

- Always disconnect the machine before servicing, and when changing accessories, such as blades, bits, cutters, and the like.

- Only use recommended accessories. Consult the operating instructions for the recommended accessories. The use of improper accessories may cause risk of injury to persons.

- Never stand on the machine. Serious injury could occur if the machine is tipped or if the cutting tool is unintentionally contacted.

- Check for damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment or binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

• Direction of work. Push the workpiece towards the sawblade or cutter only in the moving direction of the tool.
• Never leave the machine unattended while it is running. Wait until the tool has come to an absolute standstill, before you leave the machine.
• Use the correct power connection. Do not pull the power plug to stop the machine during work. Never remove the plug from the socket by pulling the extension cord.
• Always stay attentive to what you are doing, even when using the machine regularly. Bear in mind that a fraction of a second is sufficient to cause an injury.
• Keep your safety in mind. Safety is a combination of common sense and staying alert as long as the machine is switched on.

Additional Safety Regulations for the Cylinder Sanding Machine

• WARNING: Do not use your machine until it is completely assembled and installed according to the instructions.
• If you are not familiar with the operation of the sanding machine, ask the head of the department, your teacher, or any other qualified person.
• ATTENTION: This machine has only been designed for sanding wood or similar materials. The sanding of other materials can cause fire, injuries, or damage the product.

• Always wear safety goggles.

- This machine may only be operated indoors.

- IMPORTANT: Mount and use the machine on a horizontal surface. A non-horizontal surface can damage the motor.

- If the machine tends to tilt or walk (especially when sanding long and heavy panels), it must be fastened to a solid surface of sufficient carrying force.

- If you are working with larger work pieces, you should use extra support at the height of the table.

- Never use this machine, if the cylinder dust cap or the motor protective equipment is missing. Never sand deeper than 0.8 mm at one time.

- Do not sand work pieces that are shorter than 76 mm or narrower than 19 mm. Make sure that you have the correct relationship between the entry and the exit areas, and the path to the sanding cylinder. Be sure that the work piece is adequately fixed during the whole time it is being sanded.

- Keep control at all times of your work. Do not lean the work piece against the entry table.

- Do not try to carry out an unusual or uncommon work process without fixing the work piece appropriately, and before you really understand how the process works.

- Before turning on the motor, check that the adjustments and all clamping devices and screws are assure the correct and firm positioning.

- Always turn off the motor and pull out the plug, before you attempt any adjustments or change the sanding belts.

- Turn off the machine after roughly fifty hours of operation and check that the motor and the cylinder screws as well as the screws on the entry rolls are fully tightened.

- Do not force a work piece into the machine. Allow the sanding machine to work at its own speed.

- Occasionally check the entry belts, to make sure that there is no waste or sawdust among the components.

• Only sand intact wood. There should be no loose knotholes and few knotholes in general. Make sure that the work piece is free of nails, screws, stones or other alien elements that could damage the sanding cylinder or the sanding belt.
• Never stand in the direct line of the sanding band, on the entry or the exit side. Position yourself to the side of the machine.
• Make sure that the sanding belt is positioned as described in the operating instructions. A belt that is not tightened correctly may loosen during operation and damage either the work piece or the internal machine components.
• Never put your fingers into the dust exit or under the cylinder's dust cover. Wait to start sanding until the cylinder has reached full speed.
• Turn the machine off, and pull the plug out of the socket, when you install accessories or remove them.
• Never leave the work area, when the machine is turned on or not completely at a standstill.

Unpacking the Machine

Carefully remove all the pieces from the delivery carton. Do not throw away any of the packing materials, until you have found all of the parts listed on the accompanying parts list.

If a piece is missing, please ask your dealer to send it to you.

Inspect all parts in order to make sure that nothing has been damaged in transport. You must replace damaged parts before attempting to work with the machine.

Assembly

Height Adjustment Crank Fig. 2

After unpacking your sanding machine and checking the parts list for any missing components, you can mount the handle (B) for height adjustment.

Screw the height adjustment handle into the thread on the height adjustment crank (A). Use a slotted screwdriver and tighten the handle until it is firmly fixed in place.

Place the crank above the axle, so that the bolt with the latching wedge aligns with the height adjustment axle. Then secure it with the washer and dome nut (C).

Assembling the Extension Table, Fig. 3

Tighten by hand the extension table, on both sides, with the screws (D), adjust the transport band and tighten it.

We recommend affixing the machine to the base with which it is delivered.

Four screws are included for this purpose.

Adjustment

Your sanding machine was aligned and completely adjusted when it was assembled. The effects of transport may make it necessary to adjust the unit or to align it, or to return it for this work. It is very important that the following adjustments, as described below, be made.

• Warning: Never make adjustments when the machine is plugged in. Ignoring this warning can lead to serious injury.
• Warning: Always attach the machine to a workbench or a base, in order to prevent it from tipping or moving about on the table. Ignoring this warning can lead to serious injuries.

Sanding Cylinder Play, Fig. 4

Before you begin adjustments to the sanding cylinder, as described in the following, make sure that the sanding cylinder has minimal play upwards. The three most important reasons for excessive play are:

1 Too large a sanding depth. Reduce the sanding depth in order to reduce the pressure on the sanding cylinder unit. See the directions about the sanding depth in the section „Introduction to Cylinder Sanding“.
2 Loose height adjustment screws -- see the directions about the cut depth in the section on cylinder adjustment.

3 Loose attachment screws in the motor or cylinder unit -- see Fig. 4. Check that the four screws are tightened, two above and two below, and if necessary tighten them.

Adjustment of the Cylinder, Fig. 5, 6, 7, 8

• Warning: In order to avoid serious injury, always unplug the sanding machine before you begin maintenance or adjustment work.
  1 Check that the positioning screws for the hoisting tension (Fig. 5) are correct. These screws must be adjusted to make the height adjustment possible and also to limit the play of the cylinder. (If the screws are too loose, then the cylinder has too much play during sanding and this can make the surface uneven. If the screws are too tight, then it is difficult to make height adjustments.)
  2 In order to position the height adjustment screws, loosen the safety nuts, which hold the screws in place. Loosen the screws as necessary a quarter of a turn or tighten them to achieve the desired level of tightness and smooth functioning. Tighten the safety nuts again in order to fix the screws' position.
  3 Check the alignment of the sanding cylinder and the transport table. To do this, first remove the sanding belt from the cylinder. The goal of this adjustment is to maintain the same distance between points A and B, which, in turn, ensures that the cylinder is parallel to the entry table and thus allows even sanding (see Fig. 6).

If the distance A is 0.5 mm or less/larger than the same point at B, proceed as follows:

1 Loosen the two outside fastening screws (C) on the transport table, as shown in Fig. 7.
2 As necessary, push one or both of the spacers under the edge of the transport table.
3 Tighten the fastening screws on the transport table. Check once again the measurements at A and B.
4 Make a test run and check that the machine produces an even thickness. Repeat this procedure as often as necessary.

If the measurement B is 0.5 mm larger than at the same point in A, proceed as follows:

1 Loosen the two outside fastening screws (C) on the transport table, as shown in Fig. 8.
2 As necessary, push one or both of the spacers under the edge of the transport table.
3 Tighten the fastening screws on the transport table. Check, once again, the measurements at A and B.
4 Make a test run and check that the machine produces an even thickness. Repeat this procedure as often as necessary.

Positioning of the Transport Band and Tracks, Fig. 9

Due to the stretching of the band, occasional adjustment of the transport band tracks may be necessary.

1 The screws for the transport band and track adjustment are to be found on the front and back of the machine (see Fig. 9).
2 In order to increase the track tension, the track screw must be turned clockwise, while the nut is held with an 11 mm wrench (not included). In order to reduce the track tension, the track screw must be turned counter clockwise, while the nut is held with a wrench.
3 If the transport band track veers towards the inside (motor side) of the machine, then the tension on the fixing screw must be increased on this side of the machine.

Note:

Due to the width of the transport band, it is possible that a misalignment of the track is not at once evident. Increase the speed of the transport band in order to be able to monitor the effect of any adjustments. Make small corrections, of roughly a quarter of a turn, and check the results. Adjust as necessary, until the bands run correctly.

Helpful Note:

Tighten the desired track direction on the opposite side. That is, tighten the right side of the track adjustment so that the band runs to the left.

Introduction to Sanding

Function

Cylinder sanding is a repeated sanding procedure on both sides of a wooden work piece, until the desired size and/or smoothness is achieved. When this is carried out correctly, both sides of the work piece run parallel to each other.

Do not confuse cylinder sanding with planing. Depending on the coarseness, hardness of the work piece and width of the work piece, cylinder sanding removes material to 0.8 mm or less. In the case of a portable planing machine, on the other hand, one run through of the material removes up to 3.2 mm. If you can work with a planing machine, in order to smooth and plane your work piece to the size you want to attain, then you will be able quickly to learn how to work with your sanding machine and not against it. Be patient and let the cylinder sander do its work so that you can achieve the best results by removing 0.8 mm or less.

The most usual mistake when using a cylinder-sanding machine is trying to use force to remove too much material too quickly. Many variables (coarseness of the sand paper, width of the wood, the kind of wood, entry speed and wood moisture content) can influence how much material can be removed in a single pass.

Advantages of Cylinder Sanding

One advantage of a cylinder-sanding machine is that, due to its open construction, work pieces up to a width of 81 cm can be handled. Although you must still always sand with the grain, you do not need to read the grain direction in order to avoid ripping. This is especially important for thin work pieces, or for pieces with twisted or mixed grain, for example with a striped pattern.

Cylinder sanding machines put much less pressure on the wood than planing and thus give the operator the possibility of working with material as thin as veneers and thus expands his or her range of operations. Short pieces of wood, unusual forms and head wood can be sanded.

Removing Crosswise Bends in Wood

The best machine to remove cross warps in wood is a planing machine. The limited pressure applied by a sanding machine, nonetheless, can remove warps, because the wood does not lie flat on the entry band and it is not pressed against the table. Be patient. Depending on the depth of the cross warps, in the wood, this procedure can take some time. Lead the work piece into the machine, with the peak of the cross warp upwards (so that the edges rest on the band), and use a coarse grade of sandpaper. Repeat the procedure until the crown is flat on one side. Turn the work piece over and sand it flat.

Do not be surprised at how thin the wood is, after all of the warps have been removed.

Ridges and bends in the wood can not be removed from wood with a cylinder-sanding machine -- and not with a planing machine either, of course. Before starting sanding, check the wood for ridges and bends, because these can easily be caught in the machine. Short pieces of wood are particularly difficult in this aspect.

Plane Your Work Piece First

Planing reduces the time you will need for adjustment and sanding and also the operator's level of frustration. Sort your work pieces according to their thickness and the coarseness of sandpaper that needs to be used. Begin with the thickest material and work through to the thin-nest. Then change to the next, finer grade of, sandpaper and begin the procedure again.

We suggest that you experiment with various coarsenesses and kinds of wood to find out what kind of results you can achieve before you ruin a piece of wood. When new adjustments to the machine are made, be sure to make a test run with scrap material before beginning work.

Kinds of Wood That Require Caution

Wood that has a large amount of resin can quickly clog the sanding paper and in many cases, the material that collects cannot be removed with the belt cleaning brushes. This is particularly often the case with some kinds of pine. It is almost impossible to free the sanding belt from the combination of sap and sawdust.

Use care with those kinds of woods with poisonous characteristics, such as members of the tulipwood family. In spite of dust-suction, small particles can be breathed in with the room air and cause allergic reactions. For extra protection, wear a mask and gloves when working with this kind of wood.

Start Up

Warning: Never put your fingers in the dust exhaust or under the cylinder cover.

Attention: In order to avoid damage to your machine, during operation an adequate dust-suction mechanism must be attached.

Adjustment of the Cylinder Height

The cylinder moves slightly upwards, if the height adjustment (see Fig. 2) is turned in a clockwise direction. It moves downwards, if the height adjustment is turned in a counter clockwise direction. A movement of 0.4 mm corresponds roughly to a quarter turn in each direction. A complete turn thus corresponds to 1.6 mm. The depth adjustment can be read on the scale on the right side of the cylinder frame.

Please note:

When adjusting the depth for the surface sanding, the following variables should be taken into account: material hardness, width of the work piece and the selected intake speed. All these criteria are to be considered, in order to calculate the amount of material to be removed on each through pass. Never remove more than 0.8 mm on a single pass. The variable intake speed is adjusted in order to avoid burning and to produce a smoothly sanded surface in various kinds of wood and for different widths.

As a general rule, a quarter turn or 0.4 mm or less for coarser sandpaper and softer kinds of wood is recommended, while an eighth of a turn or 0.2 mm is recommended for harder woods and/or finer paper. When determining the intake speed for the material to be sanded, the rule is that the broader the material is the slower the selected intake speed should be. Equally, the intake speed should be slower for harder types of wood.

A certain amount of experimentation and practice is needed in order to become confident with the sanding performance of your machine. While surface sanding is similar to surface preparation with a planing machine, the planing machine, due to its special type of cutting edges, remove much more material with each pass. The sanding machine, on the other hand, removes a limited amount of material with the sanding medium.

Sanding

1 While the machine is still turned off, place the work piece on the entry table and push it so far forward that the height of the cylinder can be adjusted. This means the wood is to be positioned so that a uniform thickness is attained at the highest point of the work piece.
2 Close the dust-suction unit and turn this on.
3 Adjust the entry speed, according to the sanding requirements and the width of the materials.
4 Turn the machine on, place the work piece on the transport table and let the cylinder start sanding. Support a long work piece while it is being sanded, if necessary. As soon as the sanding process allows, move to the exit side of the machine, in order to catch the wood and to support it as it leaves the machine.
Note: Do not put any pressure on from the top or the bottom, when leading the work piece through the machine. If you do, you may leave marks on the sanded wood.
5 If the wood is passed through the machine several times, turn it around, while you adjust the depth of sanding with the handle (see Fig. 2). There are many variables that influence the depth chosen for sanding. These include the choice of sandpaper grain, the width of the wood, intake speed and the moisture content of the work piece.

Replacing the Sanding Belt, Fig. 10, 11, 12, 13

Warning: in order to avoid serious injury, always unplug the machine before doing any maintenance work or changing the sanding belts.

Pre-sized sanding belts, which do not require any measurement or cutting, can be bought from your dealer. These belts are conically shaped at the end. They are radially wrapped round the cylinder to create an endless strip. You can also cut your own belts to the correct size from a large roll. To do this, use the belts included in the delivery as a pattern.

1 Make sure that the switch is on OFF and the plug is pulled out.
2 Fig. 10 shows the sanding belt pattern.
3 Take either a pre-cut or a self-cut belt and begin the installation by putting the conical point in the slit on the left side of the cylinder while pushing the clip down (Fig. 11). Roughly, 25 mm of the material should be put into the slit, in order to connect it to the sanding clip. Release the clip, once the conical end is positioned firmly in the clip back. Note: You can use the worn out belts as a pattern to cut new belts.

4 Once the sanding belt is positioned firmly in the clip, stand in front of the machine and wind it radially round the cylinder. Turn the cylinder, with your right hand, away from your body and draw the material around the cylinder. Use this technique to wrap the sanding belt radially from edge to edge of the cylinder. Make sure when wrapping it round, that the sanding material does not overlap (Fig. 12). It should be smooth with a small gap but should not overlap while it is being wound around the head.
5 Once the cylinder is completely wrapped, maintain tension on the belt and lead the rest of the conical end into the cylinder slit. Using your right hand, lift up the tension clip (A) to open the chucks. Push the conical end of the sanding belt in. The tension clip insures that the sanding paper and tension are maintained when the machine is in operation, in case the belt is stretched. If the belt is not firmly positioned, then the tension clip was not raised up sufficiently to open the chucks before the belt was put in (Fig. 13).

Note: In the case where the sanding belt is stretched, it may be necessary to adjust the clip ends on the sanding belt again. Make sure that tension is always maintained during long operation.

Choice of Sanding Grain

The Sanding Process

Sanding (smoothing) of wood is a process that makes continuously finer scratches in the surface, until these scratches are so small that they are not visible to the human eye.

The grain of the sandpaper describes the coarseness of the sanding materials. The lower the grain number is, that much coarser is the sand paper and that much larger the scratches that are made on the surface. Grain 36, therefore, makes larger scratches then Grain 60, and Grain 60 is coarser than Grain 80. Coarser grain (such as, for examples, 36 and 60) can be used to remove materials aggressively and make coarse scratches on the surface, while with a grain of 220, very little material is removed and the surface becomes smoother.

Choice of Grain

Normally, the work begins with a coarse grain and moves on to ever finer grains, until the desired surface quality or material strength is attained. The choice of the initial grain depends on an evaluation of the work piece to be sanded (coarse, smooth, etc.), the width, the hardness or softness of the wood and the desired results. Below the general norms are given. (Pre-cut belts in each of the grains mentioned below can be found at your dealer and the customer service centre of our factory.)

Grain

Use and Sanding Characteristics

36 Very aggressive: maximum removal, removal of glue, sanding/planing, removes „cups“ and colour.
60 Middle aggressive: removes material, treats surface qualities, and removes glue, for sanding end grain.
80 Middle aggressive: removes material, treats surface qualities, and removes glue, for sanding end grain, removal of planing marks.
100 Middle to light surface sanding, end grain sanding, removal of planing marks.

120 Middle to fine: light surface sanding and removal of materials, for thin wood.
150 Fine: minimal removal, final sanding of a surface, thin wood.
180 Fine: final sanding.
220 Very fine: final sanding.

Warning: See to sufficient ventilation when working with solvents. Do not use solvents to clean plastic parts.

A few fundamental rules have to be followed to guarantee long-lasting and satisfying work with your grinding machine.

1 Lubricate the moving parts regularly with a lubricant, which is not oil-based. Parts to be lubricated (among others): thread depth adjustment, slide surfaces and bronze bushes with depth adjustment mechanism. Do not use oil or grease as these tend to attract and hold wood dust.
2 Check the tight fit of the frame screws and motor/cylinder mounting screws regularly.
3 Keep the grinding cylinder feed roll clean.
4 Only use clean grinding strips.
5 Check the alignment of the cylinder feeder belt and table regularly. Re-align, if necessary.

Warning: Do not operate the machine when the cylinder cover is opened. Be extremely careful during cleaning and maintenance works. Do not wear shirts with long sleeves, ties or jewellery. Tie long hair in a net when cleaning the cylinder. Otherwise, serious injuries may result.

Cleaning the grinding cylinder strips

During operation, the grinding strip gets choked with saw dust, which leads to insufficient grinding power and burning of the work piece. Check the condition of the grinding strip from time to time when the machine is switched off and the mains plug is disconnected. This has to be done more often when working with wood, which is highly resinous. Otherwise, the strip gets too choked and can no longer be cleaned. Thus it has to be replaced.

1 Observe all warning signs and be extremely careful when carrying out these cleaning works.
2 Put the speed regulator switch of the conveyor belt to the lowest speed. Avoid any contact with the belt.
3 Open the protective cover to gain access to the grinding cylinder and the grinding strip.
4 Use a long cleaning pole to keep your hands away from the rotating cylinder.
5 Switch on the machine, hold the cleaning pole in both hands and support yourself at the housing of the grinding cylinder. Then, move the pole downwards towards the rotating cylinder. Lift the pole from time to time to remove the accumulated saw dust.
6 Remove the pole when the cleaning is completed, switch off the machine and close the locking of the protective cover.

Replacing the conveyor belt

Frequent causes that make a replacement of the conveyor belt necessary are: normal wear, unintended contact with the grinding strip during grinding, cracks caused by the belt drifting sideways or excessive accumulation of a film, which cannot be removed.

The following steps describe how to replace the conveyor belt, if necessary.

1 Disconnect the machine from the power supply.
2 Lift the cylinder to its highest position (approx. 7.6 cm over the conveyor belt table) with the height adjustment handle.

3 Remove the two screws and star washers, with which the front cover is mounted to the speed regulator box, with a cross tip screw driver. Then, remove the front cover by moving it to the left and over the outer drive roll nut.
4 Remove the mounting screws of the conveyor table at the outer open side of the machine with the supplied 6mm hexagon spanner.
5 Decrease the tension of the conveyor belt by turning the inner as well as the outer belt adjustment screws anti-clockwise.
6 Remove the old belt by gripping it with both hands at both sides. Lift the conveyor table slightly at the same time. If the belt cannot be lifted, further decrease the tension to make sure that you can lift the table sufficiently high and the belt can be removed.
7 Carry out steps 6 to 3 in reversed order to mount the new belt. Centre the replaced belt on the conveyor table and create an even tension with the inner and outer track adjuster. Refer to the section „Track adjustment of the conveyor belt“, if track problems occur.
