CAUTION: When not in use, place tool on its side on
a stable surface where it will not cause a tripping or
falling hazard. Some tools will stand upright but may
be easily knocked over.
Air vents often cover moving parts and should be
•
avoided. Loose clothes, jewelry or long hair can be
caught in moving parts.
• An extension cord must have adequate wire size
(AWG or American Wire Gauge) 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.

COMPONENTS (FIG. A)
Motor
Be sure your power supply agrees with the nameplate
marking. Voltage decrease of more than 10% will cause loss
of power and overheating. These tools are factory tested; if
this tool does not operate, check power supply.

Intended Use

This hammer drill is designed for professional use.
DO nOT use under wet conditions or in presence of
flammable liquids or gases.
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.
Attaching the Side Handle (Fig. B, C)

WARNING: To reduce the risk of personal injury,
ALWAYS operate the tool with the side handle
properly installed and tightened. 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.
If your drill is equipped with a side handle, it must be
installed properly to control the drill.
1. Loosen the grip of the side handle
you can slide the side handle collar
the tool as shown.
2. To rotate the side handle into the desired position,
loosen the collar 9 by turning the side handle clockwise
and then sliding the collar into place.
3. Push the handle rearward until the slots on the lip of the
handle are alined and fully engaged with the tabs on
the underside of the gearcase.
4. Insert the depth stop rod
5. Set the drilling depth as described under Setting the
Drilling Depth.
6. Tighten the side handle by turning the grip
counterclockwise. Make sure that the side handle is
firmly secure and does not slip.
7 clockwise until
onto the front of
