MAINTENANCE AND INSPECTION

WARNING
Be sure to turn off the switch and pull out the battery before doing any inspection or maintenance.
1. Inspecting the bit
Continued use of a dull or damaged bit will result in
reduced cutting effi ciency and may cause overloading
of the motor. Replace the bit with a new one as soon
as excessive abrasion is noted.
CAUTION
If a dull bit is used, reactive force is increased
during cutting operation. Avoid the use of the
dull bit without repair.
2. Inspecting the screws
Regularly inspect all screws and ensure that they are
fully tightened. Should any of the screws be loosened,
retighten them immediately.
WARNING
Using this trimmer 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. Check for Dust
WARNING
To prevent dust inhalation or eye irritation, wear
protective safety goggles and a dust mask when
using an air gun to clean.
Use an air gun or other similar tool to remove
materials, chips, etc. which have adhered to the body
(especially where indicated in Fig. 33), and wipe with
a soft dry cloth or a cloth moistened with soapy water.
Do not use bleach, chlorine, gasoline or thinner, for
they may damage the plastics. (Fig. 33)
