An extension cord must have adequate wire size
for safety. The smaller the gauge number of the wire,
the greater the capacity of the cable, that is, 16 gauge
has more capacity than 18 gauge. An undersized cord
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. D
if this tool does not operate, check power supply.

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
clamps to the front of the gear case and
5
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
rotating it counter clockwise.
2. Place the assembly onto the putting the nose of the tool
through the steel ring
12
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
so that the assembly will not rotate.
