MAINTENANCE AND INSPECTION
CAUTION: Pull out battery before doing any inspection or maintenance.
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
reduced cutting effi ciency and may cause overloading
of the motor. Replace the blade with a new one as
soon as excessive abrasion is noted.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them
and make sure they are tight.
CAUTION
Using this power tool with loosened screws is
extremely dangerous.
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. 33)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn to or
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely within
brush holders.

5. Replacing carbon brushes
Take out the carbon brush by fi rst removing the brush
cap and then hooking the protrusion of the carbon
brush with a slotted-head screw driver, etc., as shown
in Fig. 34, Fig. 35.
When installing the carbon brush, choose the
direction so that the nail of the carbon brush (Fig. 34)
agrees with the contact portion outside the brush tube
(Fig. 36). Then push it in with a fi nger.
Lastly, install the brush cap.
