Speed change
NOTICE:
Use the tool at low speed (position 1).
Otherwise the digging operation may not be able to
complete due to insufficient torque.
NOTICE:
Use the speed change knob only after
the tool comes to a complete stop. Changing the
tool speed before the tool stops may damage the tool.
NOTICE:
Always set the speed change knob
carefully into the correct position. If you operate
the tool with the speed change knob positioned half-
way between the position 1 and the position 2, the
tool may be damaged.
Two speed ranges can be preselected with the speed
change knob.
To change the speed, depress the lock button and turn
the speed change knob so that the pointer points to the
position 1 for low speed or the position 2 for high speed.

Torque limiter
The torque limiter will actuate when a certain torque
level is reached at the low speed setting (position 1).
The motor will disengage from the output shaft. When
this happens, the drill bit will stop turning.
Strap hole
WARNING:
Do not use the strap hole for
any other purpose than hanging the tool or than
anti-theft of the tool. Otherwise personal injury may
occur.

ASSEMBLY
Installing or removing battery
cartridge
CAUTION:
Always switch off the tool before
installing or removing of the battery cartridge.
CAUTION:
Hold the tool and the battery car-
tridge firmly when installing or removing battery
cartridge. Failure to hold the tool and the battery
cartridge firmly may cause them to slip off your hands
and result in damage to the tool and battery cartridge
and a personal injury.
► Fig.13: 1. Red indicator 2. Button 3. Battery
cartridge
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Insert it all the way until it locks in place
with a little click. If you can see the red indicator on the
upper side of the button, it is not locked completely.
CAUTION:
Always install the battery cartridge
fully until the red indicator cannot be seen. If not,
it may accidentally fall out of the tool, causing injury to
you or someone around you.
CAUTION:
Do not install the battery cartridge
forcibly. If the cartridge does not slide in easily, it is
not being inserted correctly.
Mounting the auger bit
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
CAUTION:
When installing the bit adapter to
the chuck, make sure that the bit adapter is fully
inserted.
CAUTION:
When attaching the auger bit to the
bit adapter, make sure that the auger pin is locked
and inspect the auger pin for any damages.
CAUTION:
When carrying the tool, remove
the auger bit from the tool.
Installing or removing the bit adapter
To mount the auger bit, install the bit adapter in
advance.
To install the bit adapter, place the bit adapter in the
chuck as far as it will go. Tighten the chuck by rotating
the sleeve by hand.
Place the chuck key in the chuck hole and tighten clock-
wise. Be sure to tighten all three chuck holes evenly.
To remove the bit adapter, turn the chuck key counter-
clockwise in just one hole, then loosen the chuck by
hand.
