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.
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.
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. 12)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush could result in motor trouble, replace a carbon
brush with a new one 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.

7. Cleaning
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,
