DRILLING METAL
There are two rules for drilling hard materials.
First, the harder the material, the greater the
pressure you need to apply to the tool. Second,
t
he harder the material, the slower the speed.
Here are a couple of tips for drilling in metal.
Lubricate the tip of the bit occasionally with
cutting oil except when drilling soft metals such
as aluminum, copper or cast iron. If the hole to
be drilled is fairly large, drill a smaller hole first,
then enlarge to the required size, it’s often
faster in the long run. Maintain enough
pressure to assure that the bit does not just
spin in the hole. This will dull the bit and greatly
shorten its life.
DRILLING MASONRY
Soft materials such as brick are relatively easy
to drill. Concrete however, will require much
more pressure to keep the bit from spinning. Be
sure to use carbide tip bits for all masonry work.
Before using an accessory,
be certain that its maximum
safe operating speed is not exceeded by the
nameplate speed of the tool. Do not exceed
the recommended wheel diameter.
RUNNING NUTS AND BOLTS
Variable speed control must be used with
caution for driving nuts and bolts with socket
set attachments. The technique is to start
slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by slowing the
drill to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.

WARNING

Service
NO USER SERVICEABLE
PARTS INSIDE. Preventive
maintenance performed by unauthorized
personnel may result in misplacing of
internal wires and components which
could cause serious hazard.
We recom-
mend that all tool service be performed by a
Skil Factory Service Center or Authorized Skil
Service Station. SERVICEMEN: Disconnect
tool and/or charger from power source before
servicing.
BATTERIES
Be alert for battery packs that are nearing
their end of life.
If you notice decreased
tool performance or significantly shorter
running time between charges then it is time
to replace the battery pack. Failure to do so
can cause the tool to operate improperly or
damage the charger.
Long term battery storage should be in
the discharged state.
Battery packs last
longer and re-charge better when they are
stored discharged. Remember to fully re-
charge battery packs before using after
prolonged storage.
TOOL LUBRICATION
Your Skil tool has been properly lubricated
and is ready for use.
D.C. MOTORS
The motor in your tool has been engineered
for many hours of dependable service. To
maintain peak efficiency of the motor, we
recommend it be examined every six months.
Only a genuine Skil replacement motor
specially designed for your tool should be
used.
Cleaning
To avoid accidents, always
disconnect the tool and/or
charger from the power supply before
cleaning.
The tool may be cleaned most
effectively with compressed dry air.
Always
wear safety goggles when cleaning tools
with compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not attempt to clean by inserting pointed
objects through opening.
Certain cleaning agents
and solvents damage
plastic parts.
Some of these are: gasoline,
carbon tetrachloride, chlorinated cleaning
solvents, ammonia and household detergents
that contain ammonia.
