18. Maintenance

If specialist personnel must be brought in for extra-
ordinary ser vice or repairs during the warranty peri-
od and thereafter, please contact a service provider
recommended by us or con tact the manufacturer di-
rectly.
• Overhauls, maintenance work, cleaning, as well as the
eli mi nation of any malfunctions must only be underta-
ken af ter turning off the motor.
• All protective and safety equipment must be reins-
talled immediately upon completion of any repair or
maintenance work.
REGULAR MAINTENANCE
The regular maintenance decribed above and in the
para graph below can be carried out by unskilled person-
nel.
• Do not oil the plunge cut saw, cause cutting must be
carried out in dry conditions; all rotating parts are self-
lubricating.
• During maintenance, wear protective gear if possible
(accident-prevention goggles and gloves).
• Remove cuttings when necessary both from the cut-
ting area, work surfaces and support bases.
Use of an aspirator or brush is recommended.

20 GB
Possible Cause
Faulty motor, power supply cable or plug. Burned
out fuses.
Low power supply voltage. Damaged windings.
Burned out capacitor.
Damaged windings. Faulty motor.
Overloaded circuit due to lighting, utilities or other
motors.
Overload of the motor; inadequate cooling of the
motor
The saw blade is too small (sharpened too often) Re-adjust the end stop of the saw unit
The saw blade is dull; the tooth shape is not
suited to the thickness of the material
The cutting pressure is excessive or the saw
blade is not suited to the application
ATTENTION: Do not use compressed air jets!
Regularly check blade conditions: if difficulties should
arise during cutting, have it sharpened by skilled per-
sonnel or replace it if necessary.
ASSISTENCE
When in need of skilled personnel for special mainte-
nance, or for repairs, both during and following the gu-
arantee pe riod, always apply to authorized centres for

Help
Have the machine checked by skilled
personnel. Do not try to repair the machine
yourselves as it may be dangerous. Check
the fuses and replace them if necessary.
Ask for the Electricity Board to check the
voltage available. Have the machine motor
checked by skilled personnel. Have the ca-
pacitor replaced by skilled personnel.
Have the motor checked by skilled person-
nel.
Do not use other utilities or motors on the
circuit to which the plunge cut saw is con-
nected.
Prevent overloading the motor when cutting;
remove dust from the motor to ensure an
optimum cooling of the motor
Re-sharpen the saw blade or use an appro-
priate saw blade
Use the correct saw blade
