MAINTENANCE AND INSPECTION

WARNING:
To avoid an accident or personal injury, always confirm that the trigger switch is turned
OFF and the power plug has been disconnected from the receptacle before performing
any maintenance or inspection of this tool.
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 carbon brushes (Fig. 48 and Fig. 49)
The carbon brushes in the motor are expendable parts.
If the carbon brushes become excessively worn, motor trouble might occur.
Therefore, inspect the carbon brushes periodically and replace them when they have become worn to
the wear limit line as shown in Fig. 48.
Also, keep the carbon brushes clean so that they will slide smoothly within the brush holders.
The carbon brushes can easily be removed after removal of the brush caps (see Fig. 49) with a slotted
(minus) screwdriver.
3/16" (5mm)
15/32" (12mm)
3. About Handling the Motor (see Fig. 1)
Winding of the motor is said to be the heart of this tool. Exercise utmost caution not to damage the
winding by exposing it to wash oil or water.
NOTE:
Accumulation of dust and the like inside the motor can result in a malfunction.
After using the motor for 50 hours or so, carry out no-load running, and blow in the dry air
from a wind hole at the motor's rear. Such action is effective to discharge dust and the like.
4. Inspecting the screws
Regularly inspect each component of the power tool for looseness.
Re-tighten screws on any loose part.
WARNING:
To prevent personal injury, never operate the power tool if any components are loose.
5. Inspecting the lower guard for proper operation
Before each use of the tool, test the lower guard (see Fig. 8) 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.
6. 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.
