Mechanical Clutch
All rotary hammer drills are equipped with a torque limiting clutch that reduces the maximum torque
reaction transmitted to the operator in case of jamming of a drill bit. This feature also prevents the
gearing and electric motor from stalling. The torque limiting clutch has been factory-set and cannot
be adjusted.
Side Handle (Fig. 2)
_WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side handle
properly installed and securely 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
A side handle comes assembled with this rotary hammer. The side handle (H) can be fitted to suit
both right-hand and left-hand users.
TO ADJUST THE SIDE HANDLE
1. Loosen the side handle (H) by turning it counterclockwise.
2. Rotate the side handle to the desired position.
3. Tighten the side handle by turning it clockwise.
Trigger Switch (Fig. 1)
To start the rotary hammer, depress the variable speed trigger switch (A). To stop rotary hammer,
release the switch.
NOTE: Use lower speeds for starting holes without a centerpunch, drilling in metal, plastics or
ceramics, or driving screws. Higher speeds are better for drilling in masonry for maximum efficiency.
VARIABLE SPEED
The variable speed trigger switch (A) permits speed control. The farther the trigger switch is
depressed, the higher the speed of the drill.
Forward/Reverse Lever (Fig. 1)

Drilling Tools
The machine is intended for hammerdrilling in concrete, brick and stone. It is also suitable for drilling
without impact in wood, metal, ceramic and plastic.
Chipping Tools
The machine is intended for chipping in concrete, brick and stone.
Drilling
Press mode selector button (E)and turn the mode selector (D) to the drill bit symbol for drilling, to the
hammer symbol for hammering or to the hammerdrill symbol for hammerdrilling.
DRILLING OPERATION
1. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL, use high-speed
steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The exceptions
are cast iron and brass which should be drilled dry. For MASONRY, use carbide-tipped bits or
masonry bits. A smooth, even flow of dust indicates the proper drilling rate.
2. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit
biting, but do not push hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of the drill.
WARNING: Drill may staff if overloaded causing a sudden twist. Always expect the stall. Grip
the drill firmly with both hands to control the twisting action and avoid injury,
4. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL - THIS CAN
DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
7. With variable speed drills there is no need to center punch the point to be drilled. Use a slow
speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.
DRILLING IN METAL
An SDS Plus round shank adaptor chuck is required for metal drilling. Ensure that tool is in drill-only
mode. Start drilling with slow speed and increase to full power while applying firm pressure on the
tool. A smooth even flow of metal chips indicates the proper drilling rate. Use a cutting lubricant
when drilling metals. The exceptions are cast iron and brass which should be drilled dry.
NOTE: Large (5/16" to 1/2" [7.9 mm to 12.7 mm]) holes in steel can be made easier if a pilot hole
(5/32" to 3/16" [4 mm to 4.8 mm]) is drilled first.
DRILLING IN WOOD
An SDS Plus round shank adaptor chuck is required for drilling in wood. Ensure that tool is in drill-only
mode. Start drilling with slow speed and increase to full power while applying firm pressure on the
tool. Holes in wood can be made with the same twist drills used for metal. These bits may overheat
unless pulled out frequently to clear chips from the flutes. For larger holes, use spade bits, power
auger bits, or hole saws. Work that is apt to splinter should be backed up with a block of wood.
HAMMERDRILL OPERATION
1. When drilling, use just enough force on the hammer to keep it from bouncing excessively or
"rising" off the bit. Too much force will cause slower drilling speeds, overheating, and a lower
drilling rate.
2. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit
when drilling as this will cause clogging of the bit flutes and a slower drilling speed.
3. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the
hole with the tool still running to help clear debris from the hole.
4. For masonry, use carbide-tipped bits or masonry bits. A smooth even flow of dust indicates the
proper drilling rate.
