will cause a drop in line voltage resulting in loss of power
and overheating. When using more than one extension
to make up the total length, be sure each individual
extension contains at least the minimum wire size. The
following table shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use
the next heavier gauge. The lower the gauge number, the
heavier thecord.

Be sure your power supply agrees with the nameplate
marking. Voltage decrease of more than 10% will cause loss
of power and overheating.

COMPONENTS (FIG. A)

WARNING: Never modify the power tool or any part
of it. Damage or personal injury couldresult.
Refer to Figure A at the beginning of this manual for a
complete list ofcomponents.
INTENDED USE
Your heavy-duty rotary hammers is designed for
professional concrete drilling and chiselingapplications.
DO NOT use under wet conditions or in presence of
flammable liquids orgases.
Your heavy-duty rotary hammer is a professional power
tools. DO NOT let children come into contact with the tool.
Supervision is required when inexperienced operators use
thistool.
ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can causeinjury.
Side Handle and Depth Rod (Fig. B, C)

WARNING: To reduce the risk of personal injury,
ALWAYS operate the tool with the side handle
properly installed. Failure to do so may result in
the side handle slipping during tool operation and
subsequent loss of control. Hold tool with both hands
to maximizecontrol.
The side handle
5
clamps to the front of the gear case and
may be rotated 360˚ to permit right- or left-hand use.
Mounting the Straight Side Handle (Fig.B)
1. Widen the ring opening of the side handle
5
by
rotating it counterclockwise.
2. Slide the assembly onto the nose of the tool, placing
the steel ring
12
onto the collar
11
, past the bit holder
andsleeve.
3. Rotate the side handle assembly to the desired position.
For hammerdrilling horizontally with a heavy drill
bit, place the side handle assembly at an angle of
approximately 20° to the tool for optimumcontrol.
4. Lock the side handle mounting assembly in place by
securely tightening the handle
5
rotating it clockwise
so that the assembly will notrotate.

To Adjust the Depth Rod (Fig. C)
1. Push in and hold the depth rod release button
10
on
the sidehandle.
2. Move the depth rod
9
so the distance between the
end of the rod and the end of the bit equals the desired
drillingdepth.
