MAINTENANCE AND INSPECTION

CAUTION
Pull out battery before doing any inspection or maintenance.
1. Inspecting the saw blade
Since use of a dull saw blade will degrade effi ciency and cause possible
motor malfunction, sharpen or replace the saw blade as soon as
abrasion is noted.
CAUTION
If a dull saw blade is used, reactive force is increased during
cutting operation. Avoid the use of the dull saw blade without
repair.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are
properly tightened. Should any of the screws be loose, retighten them
immediately. Failure to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power tool.
Exercise due care to ensure the winding does not become damaged
and/or wet with oil or water.
4. Performance checkup and maintenance of lower guard
Keep the lower guard in good shape for smooth performance at all times.
Be sure to make prompt repair in case of any malfunction.
5. Adjusting the base and saw blade to maintain perpendicularity
The angle between the base and the saw blade has been adjusted to
90°, however should this perpendicularity be lost for some reason, adjust
in the following manner:
(1) Turn the base face up (Fig. 30) and
loosen the wing-bolt.
(2) Apply a square to the base and the saw
blade and turning the slotted set screw
with a slotted-head screwdriver, shift
the position of the base to produce the
desired right angle.
6. Check for dust
Dust may be removed with a clean rag
or a cloth dampened with soapy water.
Do not use bleach, chlorine, gasoline or thinner, for they may damage
the plastics.
7. Storage
Storing in a place below 40°C and out of the reach of children.
