WARNING
To prevent accidents, ensure that the power tool
is switched off and pull out the battery.
1. Inspecting the cutter blades
Continued use of dull or damaged cutter blades will
result in reduced cutting efficiency and may cause
overloading of the motor. Sharpen or replace the
cutter blades as often as necessary.
2. Handling
CAUTION
The front base, rear base, and cutting depth
control knob are precisely machined to obtain
specifically high precision. If these parts are
roughly handled or subjected to heavy mechanical
impact, it may cause deteriorated precision and
meduced cutting performance. These parts must
be handled with particular care.
3. 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 planer with loosened screws is
extremely dangerous.
4. Inspecting the carbon brushes (Fig. 40)
The motor employs carbon brushes which are
consumable parts. Replace the carbon brush with a
new one when it becomes worn to its wear limit.
Always keep carbon brushes clean and ensure that
they slide freely within the brush holders.
