6.15 SHUTDOWN
If the machine is to be shut down for a prolonged period of time, the parts subject to wear must be lubricated and
the machine covered with a plastic sheet and stored in a sheltered, dry place. If these instructions are observed
when work with the saw is resumed the machine will be in perfect working order.
7. MAINTENANCE
WARNING!
It is essential for all maintenance operations to be performed with the motor off and the machine
unplugged from the power supply.
Apart from the oil change in gear-motor, the machine does not require any particular maintenance operations. It is
however important to remember the following:
- Clean the machine and the work area regularly.
- Use saw blades with teeth that are suitable for the materials to be cut; this ensures optimum cutting results. Your
saw blade supplier can provide you with helpful advice.
- Replace the saw blade when it is worn, in order to avoid vibrations and inaccurate cuts.
- Clean the coolant tank when necessary or at least twice a year, through the special opening on the tank itself.
- Check the cooling pump regularly.
- Ensure that the safety guard completely covers the blade.
WARNING!
FOR ANY PROBLEMS OTHER THAN THOSE DESCRIBED ABOVE CONTACT THE MANUFACTURER
IMMEDIATELY.

TROUBLE SHOOTING
SYMPTOM
POSSIBLE CAUSE (S)
1. Incorrect blade tension
2. Incorrect speed or feed
3. Material loose in vise
4. Blade rubs on wheel flange
Excessive blade
5. Teeth too coarse for material
6. Teeth in contact with work before
breakage
saw is stared
7. Misaligned guides
8. Blade too thick for wheel diameter
9. Cracking at weld
1. Teeth too coarse
2. Too much speed
3. Inadequate feed pressure
4. Hard spots or scale in/on material
Premature blade
dulling
5. Work hardening of material
(especially stainless steel)
6. Blade installed backwards
7. Insufficient blade tension
CORRECTIVE ACTION (S)
1. Adjust to where blade just does not slip on
2. Check machinist handbook
3. Clamp work securely
4. Adjust wheel alignment
5. Check handbook for recommended blade type
6. Place blade in contact work after motor is
started
7. Adjust
8. Use thinner blade
9. Make longer annealing cycle
1. Use finer tooth blade
2. Try next lower speed
3. Decrease spring tension on side of saw.
4. Reduce speed, increase feed pressure (scale),
increase feed pressure (hard spots)
5. Increase feed pressure by reducing spring
tension
6. Remove blade twist inside out and reinstall
blade
7. Increase tension to proper level
