MAINTENANCE AND INSPECTION

WARNING
To avoid an accident or personal injury, always confirm the trigger switch is
turned OFF and that the power plug has been disconnected from the
receptacle before performing any maintenance or inspection of this tool.
Report to qualified person as soon as possible, if you discover the fault of
machine including guards or blade saw.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the first sign of deterioration
or damage.
A damaged saw blade can cause personal injury and a worn saw blade can
cause ineffective operation and possible overload to the motor.
CAUTION
Never use a dull saw blade. When a saw blade is dull, its resistance to the
hand pressure applied by the tool handle tends to increase, making it unsafe
to operate the power tool.

2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly
tightened. Should any of the screws be loose, re-tighten them immediately.
Failure to do so could result in serious hazard.
3. Inspecting the carbon brushes (Fig. 29)
The motor employs carbon brushes which are consumable parts. Since an
excessively worn carbon brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon brush No. shown in the
figure 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.
4. Replacing a carbon brushes
Disassemble the brush cap with a slotted-head screwdriver. The carbon
brushes can then be easily removed.
5. 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.
6. Inspecting the lower guard for proper operation
Before each use of the tool, test the lower guard (Fig. 5) to assure that it is in
good condition and that it moves smoothly.
Never use the tool unless the lower guard operates properly and it is in
good mechanical condition.
7. Storage
After operation of the tool has been completed, check that the following has
been performed:
(1) Trigger switch is in OFF position,
(2) Power plug has been removed from the receptacle,
When the tool is not in use, keep it stored in a dry place out of the reach of
children.
8. Lubrication

Periodically remove chips and other waste material from the surface of the
power tool with a damp, soapy cloth. To avoid a malfunction of the motor,
protect it from contact with oil or water.
