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. 30)
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

that the following has been performed:
(1) Trigger switch is in OFF position,
(2) Power plug has been removed from the receptacle,

from the surface of the power tool with a damp, soapy
cloth. To avoid a malfunction of the motor, protect it
