MAINTENANCE
CAUTION:
Be sure to switch power OFF and
disconnect the plug from the receptacle during
maintenance and inspection. Using cracked,
deformed or damaged wheels can lead to
wheel breakage and resulting serious injury.
SANDPAPER. Inspect the sandpaper. The use
of worn-out sandpaper will degrade efficiency
and cause possible damage to the pad, replace
the sandpaper as soon an excessive abrasion is
noted.
INSPECTING THE SCREWS. Regularly inspect
all screws and ensure that they are fully tight-
ened. Should any of the screws be loosened,
retighten them immediately. Using this cutter
with loosened screws is extremely dangerous.
INSPECTING THE CARBON BRUSHES. The motor
employs carbon brushes which are consumable
parts. Replace the carbon brush with a new
one when it becomes worn to its wear limit.
Always keep carbon brushes clean and ensure
that they slide freely within the brush holders.
Using this ceramic cutter with a carbon brush
which is worn in excess of the wear limit will
damage the motor.
REPLACING CARBON BRUSHES. Remove the
brush caps and carbon brushes. After replacing
the carbon brushes, do not forget to tighten
the brush caps securely.
