Maintenance And Inspection - Hitachi DS 7DF Bedienungsanleitung

4. Mounting and dismounting of the bit
(1) After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve by
turning it toward the right (in the clockwise direction
as viewed from the front). (See Fig. 6)
If the sleeve becomes loose during operation, tighten
it further. The tightening force becomes stronger
when the sleeve is tightened additionally.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by turning
it toward the left (in the counter-clockwise direction
as viewed from the front). (See Fig. 6)
CAUTION
When it is no longer possible to loosen the sleeve,
use a vise or similar instrument to secure the bit. Set
the clutch mode between 1 and 10 and then turn the
sleeve to the loose side (left side) while operating
the clutch. It should be easy now to loosen the sleeve.
NOTE
There is a plus driver bit on side of the main unit.
The bit can be removed by pulling it forward. After
using the bit, make sure to firmly attach it to the main
body again.
5. Confirm that the battery is mounted correctly.
6. Check the rotation 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
are provided on the body.)
7. Switch operation
When the trigger switch is pulled, the tool rotates.
When the trigger is released, the tool stops.
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 peep sound may be produced when the motor is
about to rotate; This is only a noise, not a machine
failure.

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. 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, as they
melt plastics.
4. Storage
