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 11 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. Confirm that the battery is mounted correctly
9. 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. 11). (The
marks are provided on the selector button.)

CAUTION:
Always use this unit with clockwise rotation, when
using it as an impact drill.
10. 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.
11. 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 hammer drill
within 10-15 kg pressing force while drilling into
brick.
12. Using the bit holder
(1) Removing the bit
and

Stow the bit in the specified location on the tool.
If the tool is used with the bit stowed improperly,
the bit may fall and cause bodily injury.
Do not stow bits that are of a different length,
gauge or dimension than the plus driver bit (65
mm long) included in the STANDARD
ACCESSORIES.
The bit may fall and cause bodily injury.
Securely hold the main unit and pull out the bit by
holding the tip with your thumb (Fig. 12).
