Operational Cautions; Maintenance And Inspection - Hitachi DS 18DBL Instruction Manual

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work
(1) The power tool is equipped with a temperature
protection circuit to protect the motor.
Continuous bolt-tightening 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

CAUTION: Pull out battery before doing any inspection or maintenance.
1. Checking the condition of the bit
The bits should be checked regularly. If worn or
broken bits can slip or decrease the efficiency of
the motor and burn it out.
Replace worn bits with new ones.
CAUTION:
If you use a driver bit of which point is worn or
broken, it will be dangerous since it slips. So
replace it with a new one.
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. 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.
4. Disposal of the exhausted battery
WARNING:
Do not dispose of the exhausted battery. The
battery must explode if it is incinerated. The
product that you have purchased contains a
rechargeable battery. 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 officials for details in
your area for recycling options or proper disposal.
(2) After use for continuous tightening wood screw
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. Storage
Storing in a place below 104°F (40°C) and out of
the reach of children.
6. Service and repairs
All quality power tools will eventually require
servicing or replacement of parts because of wear
from normal use. To assure that only authorized
