Operation (Cont’d.)
wood, metal or plastic materials, move
the hammer/drill lever to the drill
position.
DRILLING IN WOOD
For WOOD, use the low speed setting
and use twist drill bits, spade bits,
power auger bits, or hole saws.
USE ONLY in the “low speed” gear
range. 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.
When drilling in wood, composition
materials and plastic, start the drill
slowly, gradually increasing speed as
you drill. Use low speeds for plastics
with a low melting point.
When drilling in wood, the best results
are obtained with wood drills equipped
with a guide screw. The guide screw
makes drilling easier by pulling the bit
into the workpiece.
DRILLING IN METAL
For METAL, use the “DRILL” setting and
steel twist drill bits or hole saws.
USE ONLY in the “DRILL” setting. 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.
Use high speed steel twist drills or hole
saws. Use a center punch to start the
hole. Lubricate drill bits with cutting oil
when drilling in iron or steel. Use a
coolant when drilling in nonferrous
metals such as copper, brass or
aluminum. Back the material to
prevent binding and distortion on
breakthrough.
To prevent the bit from slipping when
starting a hole, make an indentation
with a center-punch and hammer at
the point to be drilled. Place the point
of the bit in the indentation and start
drilling.
DRILLING IN MASONRY
For MASONRY, such as brick, cement,
cinder block, etc., use carbide-tipped
bits rated for percussion drilling and 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.
Pressing
exces-
sively on the tool will not speed up the
drilling. In fact, this excessive pressure
will only serve to damage the tip of
your bit, decrease the tool performance
and shorten the service life of the tool.
IF DRILL STALLS, it is usually because it
is being overloaded or improperly used.
RELEASE SWITCH IMMEDIATELY,
remove drill bit from work, and
determine cause of stalling. DO NOT
CLICK SWITCH OFF AND ON IN AN
ATTEMPT TO START A STALLED DRILL
— THIS CAN DAMAGE THE DRILL.
To minimize stalling or breaking
through the material, reduce pressure
on drill and ease the bit through the
last fractional part of the hole.
Keep the motor running when pulling
the bit back out of a drilled hole. This
will help prevent jamming.
Maintenance
Tool service must be performed only
by qualified repair personnel. Service
or maintenance performed by
unqualified personnel could result in
a risk of injury.
Cleaning
Clean out dust and debris from vents
and electrical contacts by blowing with
compressed air. Keep tool handles
clean, dry and free of oil or grease.
Use only mild soap and a damp cloth
to clean the tool, keeping away from
all electrical contacts.
Certain cleaning agents and solvents
are harmful to plastics and other
insulated parts. Some of these include
gasoline, turpentine, lacquer thinner,
paint thinner, chlorinated cleaning
solvents, ammonia and household
detergents containing ammonia.
Never use flammable or combustible
solvents around tools.
LUBRICATION
For your continued safety and
electrical protection, lubrication and
service on this tool should ONLY be
performed by an AUTHORIZED
