English
CAUTION
Ascertain that the spindle lock which was used for installation and removal of the
saw blade has returned to the retract position.
2. Dismounting the saw blade.
Dismount the saw blade by following the mounting procedures in reverse order. The saw
blade can easily be changed by lifting up the lower guard.
Use only saw blades with 380 mm (15") or less diameter.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade
Since use of a dull saw blade will cause motor malfunctioning and degraded effi ciently,
replace with a new one without delay if abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should
any of the screws be loosened, retighten them immediately. Failure to do so could result in
serious injury.
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. Inspecting the carbon brushes (Fig. 15)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush could result in motor trouble, replace the carbon
brush with a new one which has the same carbon brush
No. shown in the fi gure when it becomes worn to or near
the "wear limit". In addition, always keep carbon brushes
clean and ensure that they slide freely within the brush
holders.
Replacing a carbon brush
○
Disassemble the brush cap with a minushead screwdriver. The carbon brush can then be
easily removed.
5. Inspecting lower guard functioning and its maintenance
Carefully maintain the lower guard so that it remains capable of smoothly functioning.
