General safety precautions

Do not use the machine without first reading and understanding the contents of this Operator's Manual.

WARNING! There is always a risk of crush injuries when working with products containing moving parts. Wear protective gloves to avoid body injuries.

• Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination.
• Wear personal protective equipment. See instructions under the heading Personal protective equipment.
• Keep all parts in good working order and ensure that all fixtures are properly tightened.
• Never use a machine that is faulty. Carry out the checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualified specialists. See instructions under the heading Maintenance.
• Do not modify safety equipment. Check regularly that they function as they should. The machine must not be run with defective or disassembled safety equipment.
• Never allow anyone else to use the machine without first ensuring that they have understood the contents of the operator's manual.
• People and animals can distract you causing you to lose control of the machine. For this reason, always remain concentrated and focused on the task.
• Be careful as clothing, long hair, and jewellery can get caught in moving parts.
• Observe care when lifting. You are handling heavy parts, which implies the risk of pinch injuries or other injuries.

Transport and storage

• Always switch off the power to the hydraulic unit and disconnect the hoses to the saw unit before moving the equipment.
• Dismount the blade and blade guard before transport and storage.
• Store the equipment in a lockable area so that it is out of reach of children and unauthorised persons.
  • Use the cases provided to store the equipment.

General working instructions

WARNING! This section describes basic safety directions for using a wall saw. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsafe, stop and seek expert advice. Contact your dealer, service agent or an experienced user. Do not attempt any task that you feel unsure of!

• All operators shall be trained in the use of the machine. The owner is responsible for ensuring that the operators receive training.
• Check that the blade guard is not damaged and that it has been fitted correctly.
• Never use blades other than original blades designed for the machine. Check with your Husqvarna dealer to see which blades are best suited for your usage.
  • Never use a damaged or worn blade.
• Never mount or dismount the blade or blade guard without first switching off the hydraulic unit and disconnecting the hydraulic hoses running to the saw unit.
  • Never cut without using the blade guard.
• Check that the blade is not in contact with anything when the machine is started.
• Remain at a distance from the blade when the engine is running.
• Water cooling must always be used. This cools the blades and increases their life and prevents dust build-up.
• Check that all couplings, connections and hydraulic hoses are in full working order.
• Keep the hydraulic hoses and couplings free from dirt.
• Do not misuse hoses.
• Do not use hoses that are distorted, worn or damaged.
• Check that the hoses are connected correctly to the machine and that the hydraulic couplings lock as intended before pressurising the hydraulic system. The couplings are locked by turning the outer sleeve on the female coupling so that the slot moves away from the ball.
  • Never use the hydraulic hoses to lift the saw.
• Check the machine, couplings and hydraulic hoses daily for leakage. A rupture or leak can cause a "hydraulic fluid injection" in the body or result in other serious physical injury.
• Never disconnect the hydraulic hoses without first shutting off and disconnecting the hydraulic unit and ensuring the motors have stopped completely.

• Do not exceed the specified hydraulic fluid flow or pressure for the tool being used. Excessive pressure or flow can result in rupturing.

• Hoses that are marked and approved as electrically non conductive must be used when using hydraulic tools on or in the vicinity of electrical cables. The use of other types of hoses can result in serious physical injury or even death.

• Run the hydraulic system until it reaches its operation temperature of 30 °C before starting to saw, to reduce return pressure and other wear.
• Clearly mark out all cuts to be made before you start sawing, plan these so they can be carried out without danger to persons or the machine.
• Firmly secure or anchor concrete blocks before cutting. The heavy weight of cut material can cause extensive damage if it is not moved under controlled conditions.
• Always check the back of the wall where the blade comes out when cutting through. Secure, cordon off and make sure that no people can be injured or materials damaged.
• Always check and mark out where gas pipes are routed. Cutting close to gas pipes always entails danger. Make sure that sparks are not caused when cutting in view of the risk of explosion. Remain concentrated and focused on the task. Carelessness can result in serious personal injury or death.
• Make sure that no pipes or electrical cables are routed in the area to be cut.
• Check that electrical cables within the working area are not live.
• Never leave the machine unsupervised with the engine running.
• Never saw in such a way that you cannot easily reach the emergency stop on the hydraulic unit or the stop button on the remote control. See hydraulic unit manual.
• Make sure that there is always another person close at hand when you use the machines, so that you can call for help if an accident should occur.
• People that need to be in close proximity of the machine must wear hearing protection as the sound level when cutting exceeds 85 dB(A).
• Make sure that no people or animals come closer than 4 m (15 ft) when the machine is running.
• Do not use the machine in bad weather, such as dense fog, rain, strong wind, intense cold, etc. Working in bad weather is tiring and can lead to dangerous conditions, e.g. slippery surfaces.
• Ensure that the working area is sufficiently illuminated to create a safe working environment.
  • Always ensure you have a safe and stable working position.
• Observe care when lifting. You are handling heavy parts, which implies the risk of pinch injuries or other injuries.

WARNING! Never use a blade for any other materials than that it was intended for.

Operating saw blades at rotational speeds greater than those recommended by the manufacturer can cause blade damage and possibly subsequent injury. See the Technical data section.

Basic working techniques

• Always start by cutting a pilot cut. This is done by feeding the blade 3-7 cm (1,2"-2,8"). Now make the pilot cut. The cut should not be made at maximum speed, but with care in order to obtain a straight cut and with that a basis for the next cut. The cutting arm allows blades up to 1 000 mm (40") to be used as the start blade. It is, however, recommended to start cutting with an 800 mm (31.5") blade.
• When the pilot cut is finished, a deeper cut can be made. The depth of these is determined from instance to instance and depends on factors such as hardness of the concrete, existence of reinforcing bar, etc. Max. diameter of the blade for deeper cuts is 1,200 mm (47").
• If you change blades to cut deeper in the same cut, make sure the thickness of the blade matches the width of the groove.
• Let the machine work without forcing or pressing the blade.
• Firmly secure or anchor concrete blocks before cutting. The heavy weight of cut material can cause extensive damage if it is not moved under controlled conditions.

Cutting of blocks

First make the lower horizontal cut. Now make the upper horizontal cut. Finish with the two vertical cuts.

graph TD
    A["①"] --> B["②"]
    B --> C["③"]
    C --> D["③"]
    D --> A

• If the upper horizontal cut is made before the lower horizontal cut, the work piece will fall on the blade and jam it.
• When making the last cut, the saw should be mounted on an adjacent fixed wall.

Track 400 series

• As the rail is symmetrical, the saw unit can be turned to make a new cut on the other side of the rail. In this way a cut piece is obtained that is in an easily handled size, making it easier to remove from the workplace.
• When the saw's is turned on the rail, the water jet will be positioned away from the blade and will spray in the opposite direction, possibly up towards the ceiling.

1 Mark off the cutting line and mark off the expander bolts holes 165 mm (6,5") from the cutting line.

165 mm 6,5"

2 Drill 15 mm (5/8") holes for the M12 (1/2") expander bolts.
3 If the expander bolt pulls out when the mount is fixed or when mounting on brick, stone or hollow concrete walls, it may be necessary to "through-bolt" with a piece of thread bar and a large backing plate installed on the opposite side of the wall.
4 Hang the wall mountings loosely from the expander bolts, using M6S 12 x 70 (1/2"x2") or similar.
5 Level the brackets with the leveling screws so that the top of the brackets are parallel with the plane of the wall.
6 Secure the track to the brackets with T-washers and capscrews. The gear rack should be to the side of the track nearest the cut line.
7 Adjust the distance between the cutting line and the wall mounting. The distance between the edge and the inner face of the saw cut should be 95 mm (3,7"). Tighten the expander bolts.

95 mm 3,7"

IMPORTANT! Make sure that the safety stops are fastened at each end of the track to prevent the saw from running off the track.

Connect the hydraulic unit

Please read the operator's manual supplied with the hydraulic unit before using the machine.

When the saw unit, the blade and the blade guard are mounted, the hydraulic hoses and the water cooling should be connected.

The pressure hose from the hydraulic unit shall be connected to the connector next to the start/stop switch for the blade rotation.

W T P

P=Pressure

T=Tank

W=Water

Adjust the flow to the saw unit for the desired speed of the blade. See the table in the chapter Technical data.

CAUTION! Max. flow to the saw unit is 27 GPM.

IMPORTANT! This machine is intended for use together with a Husqvarna PP 3300, Husqvarna PP 2525 and Husqvarna PP 2325. If the saw is used with another hydraulic unit, the unit must be compatible with the conditions required by the saw.

STARTING AND STOPPING

Before starting

• Enclose the area to be cut so that unauthorised persons can not be injured or disturb the operator.
• Check that the blade and th blade guard is not damaged or cracked. Replace the blade or the blade guard if it is exposed to impact or is cracked.
• Make sure that all hydraulic hoses and connections are intact and correctly connected, and that the water cooling is correctly connected and switched on.
• Check the oil level in the cutting unit. Adjust the speed valve on the saw motor to the correct position, depending on the blade diameter. (See the Cutting capacity table).

Technical line drawing of a mechanical assembly with pipes and gears (no text or symbols)

- If cutting is to begin in another position than where the saw unit is located, run the saw unit to the start position.

Starting

1 Turn on the hydraulic unit.
2 Start the blade rotation by pushing the lever for starting/ stopping the blade rotation in towards the block and then carefully pull the lever up towards the hose connector.

3 The blade is manually moved to the required depth.

Technical line drawing of a mechanical assembly with no visible text or symbols

4 Start the travel feed. Turn the handle on the directional control valve for travel feed, so that the saw moves in the required direction.

Technical line drawing of a mechanical assembly with springs and bolts (no text or symbols)

If the blade meets resistance during the cutting, a valve stops the travel feed automatically. The travel feed starts automatically again when the resistance decreases and the pressure returns to the normal.

5 The speed of the travel feed is controlled with the valve for adjustment of travel feed force. Adjust the valve to the desired position.

If the travel feed "jerks", the cause may be too high feed, which releases the valve for travel feed control and the travel feed stops. Lower the travel feed force until the feed is even.

Technical line drawing of a mechanical assembly with pipes and gears (no text or symbols)

Stopping

1 Once cutting is completed, remove the blade from the wall and shut down the blade rotation and the water flow.
2 Shut down the hydraulic unit.

Dismantling the saw

1 Allow the motor to stop completely.
2 Switch off the power to the hydraulic unit.
3 Disconnect the hydraulic hoses and the water hose from the saw unit.

The other steps are done in the reverse order to assembling.

Cleaning

The saw should be cleaned once cutting is finished. It is important to clean all the saw equipment. The saw is best cleaned with the supplied cleaning brush by connecting it to the water hose.

IMPORTANT! Do not use a high pressure washer to clean the saw.

Track 360

Adjusting the rollers

In order for the saw to run stable and cut a straight line, the rollers must be in contact with the track and not have too much play. When there is too much play between the saw carriage and track the rollers must be adjusted.

Adjusting the lower rollers

The lower rollers should be adjusted if vertical play is observed between the saw carriage and the track.

To adjust, loosen the four 6 mm socket head setscrews located at the bottom of the saw carriage. Loosening the setscrews will allow you to turn the lower eccentric bushing.

Place a 0.05-0.08 mm (0,002"-0,003") shim between the roller you are adjusting and the track. Rotate the eccentric bushing using a 27 mm (1-1/6") socket until the shim is held firmly between the roller and the track but you can still pull it out. Once this is achieved re-tigten the 6 mm socket head setscrews.

Technical line drawing of a mechanical assembly with a wrench and rotating mechanism (no text or symbols)

NOTE!

Do not over tighthen the 6 mm socket head setscrews. This could cause a slight deformity in the eccentric brushing which could cause the plunge portion of the roller to stick.

NOTE!

The upper rollers located directly underneath the saw carriage are fixed and cannot be adjusted.

Adjusting the side rollers

The side rollers should be adjusted if side play is observed between the saw carriage and the track.

To adjust, loosen the 4 mm socket head setscrew located on the side of two of the saw carriage legs. Place a 0.05-0.08 mm (0,002"-0,003") shim between the roller you are adjusting and the track. To adjust, loosen the 4 mm socket head setscrew located on the side of two of the saw carriage legs. Re-tighten the 4 mm socket head setscrew. Repeat on the other adjustable side roller.

Technical line drawing of a mechanical device with rotating components and a handle (no text or symbols)

NOTE!

Make sure that the carriage can be removed and re-installed on the track. If it is difficult to re-assemble on the track, it is being held-up by the side roller and needs to be re-adjusted for more clearance.

Adjusting the locking handle

As the saw wears, the locking handle may need to be adjusted if play is noticed between the saw head and the saw carriage.

To adjust the locking handle, loosen the two top 6 mm socket head setscrews (one on each side of the handle mount). Turn the eccentric bushing with the supplied adjustment tool until the cam lies tight against the saw head. Tighten the top 6 mm socket head setscrew. Adjust the other side. Remove saw head and tighten the lower 6 mm socket head setscrew on both sides.

Technical line drawing of a mechanical assembly with rotating components and motion arrows (no text or symbols)

Adjusting the friction stop

The friction stop must momentarily support the combined weight of the saw carriage and saw head when mounted on the track with the track mounted vertically to the wall.

To adjust the friction stop, remove the saw head from the carriage. Mount the carriage on the track and turn the friction stop setscrew clockwise to apply additional force of friction. The friction stop only needs to support the carriage and saw head until the mating gears engage.

Track 400 series

Adjusting the guide wheels

In order for the saw to run stably and saw a straight cut, the four guide wheels must rest against the rail and not have too much play. When there is too much play between the saw carriage and rail the guide wheels must be adjusted:

The two marked guide wheels have eccentric axles and by turning these the carriage is tightened onto the rail.

Technical line drawing of a mechanical assembly with two mounting holes and rail tracks (no text or symbols)

Start by loosening the marked nuts (1) with the supplied special tool. Now loosen the two stop screws (2). When these are loose, adjust the guide wheels (3) against the rail by turning them towards the rail so the play is taken up. Hold the guide wheels and screw in the stop screw. Now screw on the nuts to secure the guide wheels in the new position.

Adjust the saw carriage

As the saw wears, after a number of hours working, it can be a good idea to ensure that the saw sits firmly in the saw carriage and rail. If not, the handle probably needs adjusting:

Loosen the marked (1) socket headed screw (one on each side of the handle). Now turn the eccentric axles (2) with the help of the supplied special tool until the axle lies tight against the saw. Now tighten the socket headed screw.

Maintenance

IMPORTANT! Inspection and/or maintenance should be carried out with the motor switched off and the plug disconnected.

In addition to the daily maintenance such as cleaning and lubrication, the machine must be serviced. After 50 hours of cutting, the machine should be serviced at an accredited Husqvarna workshop. The saw should then be serviced after every 100 hours of operation. The service is important so that as the user you have a machine that works as effectively as possible for a long time.

Oil change cutting arm

There is an oil plug for draining the oil located on the cutting arm. This plug should be cleaned when changing the oil. The new oil is filled through the hole where the oil plug sits.

Technical line drawing of a mechanical assembly with no visible text or symbols

The cutting arm contains 1 dl of Husqvarna Oil 150, a transmission oil of the type EP 150. The oil should be replaced for the first time in connection with the first service. A 1 dl bottle of oil is supplied when the machine is new.

IMPORTANT! Used engine oil and transmission oil is hazardous to health and must not be disposed of in the ground or out of doors.

Lubricating the gears

There are two grease nipples on every saw unit. Through these the gears for the feeding engines can be lubricated.

Technical line drawing of a vehicle interior showing a vehicle chassis with a load valve and mounting bracket (no text or symbols)

Lubricate daily or at least every 30 hours of operation. Use VEIDEC POWER LUBE or corresponding grease.

Grease the blade spindle

In order for the blade spindle to be fitted as easily as possible, it may be necessary to grease the hexagonal blade spindle. At the same time check that the hexagon is not damaged.
