Operational Cautions; Maintenance And Inspection - HIKOKI DS 18DA Handling Instructions Manual

English

OPERATIONAL CAUTIONS

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.

MAINTENANCE AND INSPECTION

WARNING
To avoid serious accident, ensure the switch is in the OFF position, and pull out the
battery.
1. Inspecting the tool
Since use of a dull tool will degrade effi ciency and cause possible motor malfunction,
sharpen or replace the tool as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should
any of the screws be loose, retighten them immediately. Failure to do so could result in
serious hazard.
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. 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.
5. Cleaning of the outside
When the driver drill is stained, wipe with a soft dry cloth or a cloth moistened with soapy
water. Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.
6. Storage
Store the driver drill in a place in which the temperature is less than 40°C and out of reach
of children.
NOTE
Storing Lithium-ion Batteries
Make sure the 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 time or rendering the
batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may be recovered by repeatedly
charging and using the batteries two to fi ve times.
