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 efficiency 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. Check the mounting screws
Loose mounting screws are dangerous. Regularly inspect them and make sure they are tight.
CAUTION: Using this power tool with loosen, screws is extremely dangerous.
3. 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.
4. 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. 24) 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 de-
sired right angle.
5. 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.
