OPERATIONAL CAUTIONS

Resting the unit after continuous work
(1) The power tool is equipped with a temperature
protection circuit to protect the motor.
Continuous work may cause the temperature of the
unit to rise, activating the temperature protection
circuit and automatically stopping operation.
If this happens, allow the power tool to cool before
resuming use.

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 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.
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 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
Dust may be removed with a soft cloth or a cloth
dampened with soapy water.
Do not use bleach, chlorine, gasoline or thinner, for
they may damage the plastics.

Remove the cause of the overburdening.
Allow the tool and battery to thoroughly
cool.
(2) After use for continuous works, rest the unit for
15 minutes or so when replacing the battery. The
temperature of the motor, switch, etc., will rise if
the work is started again immediately after battery
replacement, eventually resulting in burnout.
5. Lubrication
The bearings in this tool have been suffi 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.
6. Disposal of the exhausted battery
WARNING
Do not dispose of the exhausted battery. The
battery must explode if it is incinerated. The
battery is recyclable. At the end of it's useful
life, under various state and local laws, it may
be illegal to dispose of this battery into the
municipal waste stream. Check with your local
solid waste offi cials for details in your area for
recycling options or proper disposal.
7. Storage
Storing in a place below 104°F (40°C) and out of the
reach of children.
NOTE
Storing lithium-ion batteries
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries
with a low charge may result in performance
deterioration, signifi cantly reducing battery usage
