WARNING
To avoid an accident or personal injury, always
confirm the trigger switch is turned OFF and that
the battery or AC/DC adapter has been
disconnected from the power tool before
performing any maintenance or inspection of this
tool.
Report to qualified person as soon as possible, if
you discover the fault of machine including
guards or blade saw.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the
first sign of deterioration or damage.
A damaged saw blade can cause personal injury and
a worn saw blade can cause ineffective operation and
possible overload to the motor.
CAUTION
Never use a dull saw blade. When a saw blade is
dull, its resistance to the hand pressure applied
by the tool handle tends to increase, making it
unsafe to operate the power tool.
2. 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.
NOTE
Accumulation of dust and the like inside the motor
can result in a malfunction.
After using the motor for 50 hours or so, carry out no-
load running, and blow in the dry air from a wind hole
at the motor's rear. Such action is effective to
discharge dust and the like.
3. Inspecting the screws
Regularly inspect each component of the power tool
for looseness.
Re-tighten screws on any loose part.
WARNING
To prevent personal injury, never operate the
power tool if any components are loose.
4. Inspecting the lower guard for proper operation
Before each use of the tool, test the lower guard (see
Fig. 16) to assure that it is in good condition and that it
moves smoothly.
MAINTENANCE AND INSPECTION
Never use the tool unless the lower guard operates
properly and it is in good mechanical condition.
5. 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.
6. Lubrication
Lubricate the following sliding surfaces once a month
to keep the power tool in good operating condition for
a long time (see Fig. 3 and Fig. 4). Use of machine oil
is recommended.
Oil supply points:
○ Rotary portion of hinge
○ Rotary portion of vise assembly
○ Rotary portion of holder (A)
7. Cleaning
Duct
Air gun
Clean the machine, duct and lower guard by blowing with
dry air from an air gun or other tool.
Periodically remove chips, dust and other waste material
from the surface of the power tool, especially from the
inside of the lower guard with a damp, soapy cloth. To
avoid a malfunction of the motor, protect it from contact
with oil or water.
If the LED light becomes invisible due to chips and the like
adhered onto the window of the LED's light-emitting
section, wipe and clean the window with a dry cloth or a
soft cloth moistened with soapy water, etc.
