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;
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
DRILLING IN MASONRY
For MASONRY, such as brick, cement, cinder block, etc., use
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.
LUBRICATIONFor your continued safety and electrical protection, lubrication and service on this tool should ONLY be performed by an AUTHORIZED CAMPBELL HAUSFELD SERVICE CENTER.
