HAMMERHOOK
Your tool is equipped with a convenient hook
for hanging your tool. To use, simply open
hook until it snaps into the open position
(Fig. 7).
When using the HAMMERHOOK™ always
be aware that the accessory is exposed.
Always hang the tool in an area where
yourself and bystandards can not accidently
make contact with the accessory.
To reduce the risk of injury,

WARNING
use care in selecting the
location for hanging the tool.
• Select a suitably sized and shaped object
that will provide adequate hanging stability.
An unstable hanging surface could result in
the tool unexpectedly falling.
• Insure that the tool is hung out of the way of
walkways and
bystanders. The tool could be bumped or a
bystander could become entangled in the
power supply cord causing the tool to
unexpectedly fall.
TOOL TIPS
Following a few simple tips will reduce wear
on the tool and the chance of injury to the
operator.
NOTE: The high efficiency available from
the rotary hammers can only be obtained if
sharp and undamaged accessories are used.
The "cost" to maintain sharp and undamaged
accessories is more than offset by the "time
saved" in operating the tool with sharp
accessories.
All hammers require a short period of time to
warm up. Depending on the room
temperature, this time may vary from
approximately 15 seconds (90˚F) to 2
minutes (32˚F). A new hammer requires a
break-in period before full performance is
realized. This period may require up to 5
hours of operation.
Carbide tipped bits: Used for drilling stone,
concrete, cement, brick, cinder block and
other unusually hard non-metals. The Rotary
Hammer is designed for "SDS" Carbide
Tipped Bits up to 3/4 inch diameter.
3 JAW CHUCK
The 3 Jaw Chuck with SDS Shank Adaptor
accessory can convert your tool for use with
straight shank bits.

WARNING
Do not use the hanging hook
if it appears damaged or deformed. This
could result in unstable hanging and the tool
unexpectedly falling.

To Open
HAMMERHOOK
When not in use, always
close hook until it snaps
into the closed position.
You will extend the life of your bits and do
neater work if you always put the bit in contact
with the workpiece BEFORE pulling the
trigger. During operation, hold the drill firmly
and exert moderate, steady pressure. Too
much pressure at low speed will stall the
hammer. Too little pressure will keep the bit
from cutting and cause excess friction by
sliding over the surface. This can be
damaging to the drill and bit.
Shanks of all drill bits should be wiped clean
prior to using and immediately after removing.
Recall these instructions for safe operation:
1. Some materials require slow drilling
speeds; whereas, others require higher speed
to produce the best results.
2. All work must be supported or secured
before drilling and steady, even pressure
applied in line with the drill bit.
3. As the drill bit cuts through the opposite
side, reduce the pressure and continue
running the drill as the bit is withdrawn.
Materials such as glass, porcelain, ceramics,
tiles, plastics, etc., should be drilled at low
speeds with specially designed drill bits and
lubricants.
