English
NOTE
If the sleeve is tightened in a state where the clip of
the keyless chuck is opened to a maximum limit, a
click noise may occur. This is the noise that occurs
when the loosening of the keyless chuck is prevented
and is not a malfunction.
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 7 and then turn the
sleeve to the loose side (left side) while operating the
clutch. It should be easy now to loosen the sleeve.
8. Automatic spindle-lock mechanism
This unit has automatic spindle-lock mechanism for
quick bit changes.
9. Confirm that the battery is mounted correctly
10. 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. 9). (The
marks are provided on the selector button.)
CAUTION
Always use this unit with clockwise rotation, when
using it as an impact drill.
11. Switch operation
When the trigger switch is depressed, 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 buzzing noise is produced when the motor is about
to rotate. This is only a noise, not a machine failure.
12. For drilling into brick
Excessive pressing force never increases drilling
speed. It will not only damage the drill tip or reduce
working efficiency, but could also shorten the service
life of drill bit. Operate the impact driver drill within
10-15 kg pressing force while drilling into brick.
13. Using the hook
CAUTION
When using the hook, pay sufficient attention so that
the main equipment does not fall. If the tool falls,
there is a risk of accident.
Do not attach the tip tool except phillips bit to the tool
main unit when carrying the tool main unit with the
hook suspended from a waist belt.
Injury may result if you carry the equipment
suspended from the waist belt with sharp tipped
components such as drill bit attached.
The hook can be installed on the right or left side and the
angle can be adjusted in 5 steps between 0° and 80°.
(1) Operating the hook
(a) Pull out the hook toward you in the direction of
arrow (A) and turn in the direction of arrow (B)
(Fig. 10).
(b) The angle can be adjusted in 5 steps (0°, 20°, 40°,
60°, 80°).
Adjust the angle of the hook to the desired position
for use.
