Operation
DRILLING
1. Always lock the trigger switch and remove the battery when
attaching or changing bits or accessories.
2. Use sharp drill bits only. For WOOD, use the low speed setting and
twist drill bits, spade bits, power auger bits, or hole saws. For
METAL, use the low speed setting and 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 OFF AND ON IN AN ATTEMPT 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
All manuals and user guides at all-guides.com
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") holes in steel can be made easier if a
pilot hole (5/32" to 3/16") 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. 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. Be certain that the bit is sharp. Ensure that the hammer mode
is selected. Use a constant and firm force on the tool to drill most
effectively. A smooth, even flow of dust indicates
the proper drilling rate.
SDS Chuck
To insert bit , insert shank of bit about 3/4" into
chuck and twist the bit until it clicks into place. The
bit will be securely held.
To release bit, pull the collar back and remove
the bit.
Maintenance
CLEANING
Use only mild soap and damp cloth to clean the tool. Never let any liquid
get inside the tool; never immerse any part of the tool into a liquid.
Self-lubricating bearings are used in the tool and periodic relubrication
is not required. In the unlikely event that service is ever needed, take
your tool to an authorized service location.
