Maintenance And Inspection - Hitachi DB 10DL Bedienungsanleitung

English
CAUTION
The motor rotation may be locked to cease while the
unit is used as drill. While operating the driver drill,
take care not to lock the motor.
If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor or
battery may be burnt.
Too long hammering may cause the screw broken
due to excessive tightening.
7. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn the
bit counterclockwise (See Fig. 7) (The
marks are provided on the body).
8. Switch operation
When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.

CAUTION:
The selection examples shown in Table 3 should be
considered as general standard. As different types of
tightening screws and different materials to be
tightened are used in actual works proper adjustments
are naturally necessary.
NOTE:
The use of the battery BCL1015 in a cold condition
(below 0 degree Centigrade) can sometimes result in
the weakened tightening torque and reduced amount
of work. This, however, is a temporary phenomenon,
and returns to normal when the battery warms up.
12. Battery Level Warning Lamp
The battery level can be checked by pulling the trigger
switch while the power tool is in a no-load state. The
battery level warning lamp lights when the battery
power is very low. If this happens, charge the battery.
(Fig. 9)
NOTE:
The level at which the battery level warning lamp
lights may vary due to the ambient temperature,
characteristics of the battery, etc. and is intended
only as a guide.

The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly
and increases as the trigger switch is pulled more.
NOTE
A buzzing noise is produced when the motor is about
to rotate. This is only a noise, not a machine failure.
9. Using the light
Pull the trigger switch to light up the light. The light
keeps on lighting while the trigger switch is being
pulled. The light goes out after releasing the trigger
switch. (Fig. 8)
CAUTION:

Do not look directly into the light. Such actions could
result in eye injury.
10. The scope and suggestions for uses
The usable scope for various types of work based on
the mechanical structure of this unit is shown in
Table 2.

Suggestions
The battery level warning lamp may light when the
power tool is overloaded. This does not mean that
the battery power is very low.
Be sure to check the battery level while the tool is in a
no-load state.

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Since use of as dull tool will degrade efficiency 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. Cleaning on 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.
5. Storage
Store the driver drill in a place in which the
temperature is less than 40°C and out of reach of
children.
