5. Clean inside the saw cover
Periodically inspect and clean the saw cover to
ensure that there is no accumulation of chips or other
particles.
6. Check for dust
Dust may be removed with a clean rag or a cloth
dampened with soapy water.
Do not use bleach, chlorine, gasoline or thinner, for
they may damage the plastics.
7. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have
collected on the terminals.
Failure to do so may result in malfunction.
8. Lubrication
The bearings in this tool have been su
ffi
ciently
lubricated with quality lubricating oil, taking into
account the expected life of this tool under normal
operating conditions. As a result, no further lubrication
is necessary.
1. Inspecting the saw blade
Continued use of a dull or damaged blade will result in
reduced cutting e
ffi
ciency and may cause overloading
of the motor. Replace the blade with a new one as
soon as excessive abrasion is noted.
CAUTION
If a dull saw blade is used, reactive force is
increased during cutting operation. Avoid the
use of the dull saw blade without repair.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them
and make sure they are tight.
CAUTION
Using this power tool with loosen, screws is
extremely dangerous.
3. Motor unit maintenance
The motor winding is an important part of this tool.
Avoid damaging and be careful to avoid contact with
cleaning oil or water.
After 50 hours of use, clean the motor by blowing into
the ventilation holes of the motor housing with dry air
from an air gun or other tool (Fig. 35).
Dust or particle accumulation in the motor can result
in damage.
4. Inspecting and maintaining the lower guard
Always make sure that the lower guard moves
smoothly.
In the event of any malfunction, immediately repair the
lower guard.
For cleaning and maintenance, use an air gun or other
tool to blow clean the space between the lower guard
and gear cover as well as the rotation part of the lower
guard with dry air (Fig. 35).
Doing so is e
ff
ective for the emission of chips or other
particles.
Accumulation of chips or other particles around the
lower guard may result in malfunction or damage.
WARNING
To prevent dust inhalation or eye irritation, wear
protective safety goggles and a dust mask when
using an air gun or other tool to clean the lower
guard, ventilation holes or other parts of the
product.
