Before further use of the tool, a
guard or other part that is dam-
aged should be carefully checked
to determine that it will operate

working conditions. Use this and
other machinery with caution and
respect. Failure to do so could result
in serious personal injury, damage
to equipment or poor work results.
12. SECURE WORK. Use clamps or a
vise to hold work when practical. It’s
safer than using your hand and frees
both hands to operate tool.
13. DON’T OVERREACH. Keep proper
footing and balance at all times.

OPERATION INSTRUCTIONS
Mode Selector Switch
Inserting And Changing Bits
You can achieve the three functions of the
hammer drill by selecting the various com-
binations of front and back switches. Refer
to Figure 2 for more details.
Clean and lightly oil the selected bit before
inserting. Pull back the locking sleeve and
slide bit into hammer drill. Twist bit with
slight inward pressure until it moves further
into the hammer drill. Release locking
sleeve and make sure that bit is secured in
place and will not come out by hand. For
removal, pull back locking sleeve and slide
bit straight out of hammer drill.
Drill Mode
Operation
Hammer Drill Mode
1. The hammer drill can be started and
stopped by simply pressing and releasing
the trigger switch.
2. For safety reasons, you should always
use the auxiliary handle during use. If the
hammer drill locks up, the auxiliary handle
will help you maintain control and
decrease your chances of injury. To adjust
the auxiliary handle, twist it counterclock-
wise until it is loose enough to position
where you need it, then twist clockwise to
tighten.
Power Chisel Mode
Fig 2. Functions of Hammer Drill
3. Setting the depth gauge rod can be
done by loosening the auxiliary handle and
inserting the rod into the hole on the auxil-
iary handle near the body of the hammer
drill. Tighten handle when your desired
length is achieved.
Maintenance
It is important that you always keep the
device and ventilation slots clean. Aside
from lubricating bits before insertion, all
other repairs or maintenance to the inter-
nal parts of the tool should be done by a
qualified service technician.
4. The dust protection cap can be fitted on
the bottom end of the bits before you insert
them into the hammer drill. This will help
prevent to a large extent the entry of
drilling dust. The hollow side of the dust-
cap should face body of the hammer drill.
Disassembly and improper reassem-
bly of this device can result in electri-
cal shock danger. Always have this
device serviced by a qualified electri-
cal repair technician. Serious injury
will result.
5. It is important that you don’t apply too
much pressure to the hammer drill during
operation. Excessive force puts unneces-
sary stress on the motor and increases
likelyhood of getting hurt. If speed drops
suddenly during use, decrease pressure
immediately.
