• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities. Wear protective clothing and wash exposed areas
with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may
promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.
WARNING: Always wear proper personal hearing protection that conforms to ANSI
S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product
may contribute to hearing loss.
• The label on your tool may include the following symbols. The symbols and their definitions
are as follows:

Motor
Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than
10% will cause loss of power and overheating. D
not operate, check power supply.
COMPONENTS (Fig. 1, 2)
WARNING: Never modify the power tool or any part of it. Damage or personal injury could
result.
A. Side handle
B. Trigger switch
Side Handle (Fig. 1)
CAUTION: Always use side handle (A) and hold rotary hammer with both hands.. It clamps
to the front of the gear case as shown and can be rotated 360˚ to permit right or left hand use.
The grip may be unscrewed and retightened to relocate the handle in the desired location.
Switch (Fig. 1)
The variable speed trigger switch (B) permits speed control. The farther the trigger switch is
de pressed, the higher the speed of the rotary hammer.
NOTE: Use lower speeds for starting holes without a center punch, drilling in metal, plastics or
ceramics, or driving screws. Higher speeds are better for drilling in wood and composition board
and for using abrasive and polishing accessories.
Mode Selector (Fig. 2)
CAUTION: Never change the mode while the unit is running.
For straight drilling, rotate the mode selector (C) until the arrow points to the drill bit symbol. For
rotary hammer, align the arrow with the hammer symbol. For chipping mode align arrow with
the chipping symbol.
NOTE: The mode selector (C) must be in drill, hammer or chipping mode at all times. There are
no operable positions in between.
OPERATION
WARNING: To reduce the risk of injury, turn unit off and disconnect it from power
source before installing and removing accessories, before adjusting or when making
repairs. An accidental start-up can cause injury.
Depth Rod
To adjust the depth rod (D), loosen the wing nut (E) and move rod so that the distance between
the end of the rod and the end of the bit equals the desired drilling depth. Tighten the wing nut.
When drilling with depth rod, stop when end of rod reaches surface of material.
Quick Change SDS Chuck (Fig. 3)
The SDS chuck can be easily removed by turning the collar (F) into the unlocked position (G) to
release the chuck.
The SDS chuck can be easily attached by inserting the chuck into the spindle of the tool and
turning the collar to the locked position (H). The chuck will click when properly installed.
Drilling
1. Always unplug the drill when attaching or changing bits or accessories.
2. Always use sharp drill bits. For WOOD, use twist drill bits, spade bits, power auger bits, or
hole saws. For METAL, use steel twist drill bits or hole saws. For MASONRY, such as brick,
cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling.
3. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a
wood "back-up" block to prevent damage to the material.
4. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill biting,
but do not push hard enough to stall the motor or deflect the bit.
5. Hold tool firmly to control the twisting action of the drill.
6. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE
TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO
NOT CLICK TRIGGER ON AND OFF IN AN AT TEMPT TO START A STALLED DRILL —
THIS CAN DAMAGE THE DRILL.
7. To minimize stalling or breaking through the material, reduce pressure on drill and ease the
bit through the last fractional part of the hole.
8. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
9. 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
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. The cutting
lubricants that work best are sulphurized cutting oil or lard oil; bacon-grease will also serve the
purpose.
NOTE: Large [5/16" to 1/2" (7,6 mm to 13 mm)] holes in steel can be made easier if a pilot hole
[5/32" to 3/16" (3,8 mm to 5 mm] is drilled first.
DRILLING IN WOOD
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.
DRILLING IN MASONRY
When drilling in masonry, use carbide tipped bits rated for percussion drilling and be certain that
the bit is sharp. Use a constant and firm force on the tool to drill most effectively. A smooth, even
flow of dust indicates the proper drilling rate.
