SPECIAL INSTRUCTIONS

The disc cutter is designed to provide safe and reliable service in operating conditions corresponding with the instructions, but it can present dangers for the user and risks of damage, consequently regular on site inspection is necessary to ensure :

- Perfect technical condition (use for the purpose for which it is intended and taking into account any risks, and correction of any malfunction detrimental to safety).

- Use a diamond disk for cutting with water (sawing new or old concrete, tarmac or asphalt). No other type of disk is allowed (abrasive, saw, etc...).

- Competent staff (qualifications, age, training) who have read and understood the manual in detail before starting work: any electrical, mechanical or other problem should be investigated by a qualified maintenance engineer (electrician, maintenance manager, approved dealer, etc...).

- That the warnings and instructions marked on the machine are followed (adequate personal protection, correct use, general safety instructions, etc).

- That no modification, transformation or addition is detrimental to safety and that it is carried out without prior authorization from the manufacturer.

- Respect of the maintenance intervals and periodical checks recommended.

- That only genuine spare parts are used for repairs.

FAILURE TO COMPLY WITH THESE WARNINGS COULD RESULT IN DEATH OR SERIOUS BODILY INJURY.

DO

Handling - Transport

Switch off the disk prior to moving the machine on jobsite.

Remove the disk prior to hoisting, loading, unloading and transporting the machine on jobsite.

Height of adjustable handlebars (unscrew the lever (M)) [SEE FIG. 2].

• The ground-saw only needs pushing to move it into position on the site. It is easy to move on its four wheels, without starting the motor.
• The handwheel (K) locks the machine itself in the high position.
• Light weight, compact, transportable in a vehicle by one person.

Check before starting

Please read the instructions for use prior to operating the machine for the first time.

Motor off.

The working area must be completely cleared, well lit and all safety hazards removed (no water or dangerous objects in the vicinity)

The operator must wear protective clothing appropriate to the work he is doing. We recommend that this includes both eye and ear protection

The use of ear protection is mandatory.

Any persons not involved in the work should leave the working area

Use only blades marked with a maximum operating speed greater than blade shaft speed

Take into account the working conditions from health and safety point of view.

• Model with petrol motor (refer to the motor maintenance manual).
  ■ Make sure the fuel is topped up.
  ■ Check the oil level; as the motor often works at an angle, check it frequently in the horizontal position that the oil level is never below the second line on the gauge.
  ■ To start up, refer to the motor instructions.

Fitting the blade

Motor off

• Place the machine in an high position.

• Make sure the engine is switched off.

• Unscrew the nuts (E) from the guard housing [SEE FIG. 3].

• Remove the guard housing (A).
• Fit the diamond impregnated disc.

Note the direction of rotation indicated by an arrow on one side of the disc (direction of rotation shown on the outside of the guard housing).

Check the state of cleanliness of the disc support faces of the adaptor plates (B and C) and of the spindle.

• Firmly tighten the screw (D) with the spanner provided with the machine, holding the disc steady by hand.
• Replace the protective guard (if this is not replaced the casing safety switch will prevent the saw being started).
• Reconnect the water hose (mains with valve or tank).
• Tighten the nut (E).

The holding screw (D) of the disc has a right-hand thread.

Starting up

Always pay extreme care and attention to the preparation of the machine before starting up

Remove all adjustment tools and wrenches from floor and machine

Always keep blade guard in place

• Turn off the water tap (G) (from the mains or from the tank in order to fill it) [SEE FIG. 4].
• Mark out a line on the ground where a cut has to be made.
• Position the machine so that the lowered front guide (F) and the disc are aligned with the line marked out (disc visible on the belt side of the housing).
• Start up the motor : refer to the motor manufacturer's instructions in the service manual.
• Allow the motor to warm up.
• Turn on the water supply tap (G) (from the mains or the water tank).
• Increase the motor speed to full.
• Hold the saw, turn the handwheel (K) and position the disk in contact with the floor.
• Lower to the depth of cut required, and bearing in mind that each graduation of the scale corresponds to a depth of 1cm. Lower slowly to prevent the engine stalling.
• Gently move the machine forward ensuring that the front guide and the disc are always aligned with the line marked out.

Ensure that the water supply is abundant, when cutting wet.

Stopping the machine

Motor off

• Turn the handwheel (K) to free the disk from the groove [SEE FIG. 4]
• No need to lock the saw up by releasing the handwheel (K).
• Turn off the water supply (G).
• Allow the motor to run idle.
• Switch off the motor (refere to the motor maintenance manual).

Emergency stop

Operate the switch (J) in front of the engine.

Incidents during sawing

- There may be several causes responsible for arresting the disc in the sawing groove or stopping the machine:

■ Belt tension.
■ Lack of fuel.
■ Advance or lowering too fast, etc.

- In all case, disengage the disc from the groove and give the machine a complete check-over.

Entrust repairs to authorised dealer only

Maintenance (with the engine stopped)

"Engine Maintenance": refer to the engine maintenance booklet.

• After use, clean the machine.
- Lubrication : apply a moderate amount of bearing lubricant to the nipples in the depth adjustment chassis (depending on the frequency of use).

OIL

- Check the engine oil everyday. Refer to the engine manual for oil change schedule. Use :

■ SAE 10W30 motor oil with API class MS, SD, SE or better for PETROL engines.
■ API class CD or CE for Hatz diesel.

Dispose of the old oil as laid down by the regulations in force.

- To change the oil, remove the disk, lower the saw to the lowest position and then place the tray by the drain outlet (L) [SEE FIG. 4].

Store in a safe place, out of reach of children

Maintain tools carefully

AIR FILTER

• Read engine owners manual for maintenance intervals. For extremely dusty conditions you may have to clean the air filter element 2 to 3 times a day.
• Replace any damaged filters or gaskets.

Store in a safe place out of reach of children.

Remove all adjustment tools and wrenches

Store diamond tool in a safe place so it cannot be bent or damaged.

11 Engine belt tension

It may be necessary after using a few times to retention the belts, without over-tightening them. To do this :

• loosen the 2 nuts (S) fixing the motor to the chassis, without removing them [SEE FIG. 5];
• tighten the tensioning nuts (N), these screws pull the motor up.
• at normal tension, tighten the motor fixing nuts (S).

12 Important advice

• Periodically, tighten the nuts and bolts and particularly after the first few hours of use.
• Check belt tensions, tighten them without overdoing it.
• When garaged, it is recommended the disc be removed and suitably stored.
• Make sure the disc is correctly tightened.
• Make sure the disc supports surfaces, the adaptor plates and the spindle are kept clean.

The manufacturer declines all responsibility for loss or damage resulting from misuse or any modification, alteration or powering that does not conform to the manufacturer's original specifications.

At the work station, the sound pressure level may exceed 85 db (A)

In this case individual protection measures must be taken.

When working in a limited or closed area, make sure that the ventilation is adequate. The exhaust gases contain carbon monoxide (exposure to this toxic gas can cause loss of consciousness and can be fatal).

13 Repairs

We carry out all repairs in the shortest possible time and at the most economical prices (see overleaf for our address).

14 Spare parts

For quick supply of spare parts and to avoid any lost time it is essential to quote the data on the manufacturer's plate fixed to the machine and the part number of the part to be replaced with every order.
