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, the 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.
!WARNING 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.
Maintenance
Service
!WARNING 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
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 ! WARNING 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 ! CAUTION and solvents damage
plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.
