OPERATION
WARNING To reduce the risk of injury, always unplug tool before attaching or remov- ing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous.
WARNING To reduce the risk of injury, wear safety goggles or glasses with side shields.
Using Forward/Reverse Switch | ||
1. For forward (clock- |
| |
wise) rotation, push | Forward | |
the forward/reverse | ||
| ||
switch to ◄as shown. |
| |
2. For reverse (counter- |
| |
clockwise) rotation, |
| |
push the forward/re- |
| |
verse switch to ►. |
| |
Although an interlock | Reverse | |
prevents reversing the | ||
tool while the motor is |

running, allow it to come to a full stop before reversing.
WARNING To reduce the risk of injury, keep hands and cord away from the bit and all moving parts.
WARNING High rotational force. To reduce the risk of injury, always hold or brace securely.
Starting, Stopping and Controlling Speed
1.To start the tool, pull the trigger.
2.To stop the tool, release the trigger.
3.To vary the drilling speed, increase or decrease pressure on the trigger. The further the trigger is pulled, the greater the speed.
WARNING To reduce the risk of explo- sion, electric shock and property damage, always check the work area for hidden pipes and wires before drilling.
Drilling
1.Before drilling, be sure the workpiece is clamped securely. Use backing material to prevent dam- age to the workpiece during breakthrough.
2.When starting a hole, place the drill bit on the work surface and apply firm pressure. Begin drilling at a slow speed, gradually increasing the speed as you drill.
3.Always apply pressure in line with the bit. Use enough pressure to keep the drill biting, but do not push hard enough to stall the motor.
4.Reduce pressure and ease the bit through the last part of the hole. While the tool is still running, pull the bit out of the hole to prevent jamming.
Stalling
If the tool seems as if it is about to stall, maintain a firm grip and reduce pressure slightly to allow the bit to regain speed. If the tool does stall, release the trigger immediately. Reverse the motor, remove the bit from the work and start again. Do not pull the trigger on and off in an attempt to start a stalled drill. This can damage the drill.
APPLICATIONS
Selecting Bits
When selecting a bit, use the right type for your job. For best performance, always use sharp bits.
Drilling in Wood, Composition Material & Plastic When drilling in wood, composition materials and plastic, start the drill slowly, gradually increasing speed as you drill. When using twist drill bits, pull the bit out of the hole frequently to clear chips from the bit flutes. Use low speeds for plastics with a low melting point.
Drilling in Masonry
When drilling in masonry, use high speed carbide- tipped bits. Drilling soft masonry materials such as cinder block requires little pressure. Hard materials like concrete require more pressure. A smooth, even flow of dust indicates the proper drilling rate. Do not let the bit spin in the hole without cutting. Do not use water to settle dust or to cool bit. Both actions will damage the carbide.
Drilling in Metal
When drilling in metal, use high speed steel twist drills or hole saws. Use slow speeds for hard metals and high speeds for softer metals. 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.
Driving Screws
When driving screws, use the proper screwdriver bit for your job. After drilling pilot and shank holes, start the screw slowly and increase the speed as driving progresses. Set the screw by slowing to a stop. Do not run screws down at excessive speeds. To remove screws, reverse the motor.
WARNING High rotational force. To reduce the risk of injury, always hold or brace securely.
Bit Binding
A high rotational force occurs when a bit binds. If the bit binds, the tool will be forced in the opposite direction of the bit rotation. Bits may bind if they are misaligned or when they are breaking through a hole. Wood boring bits can also bind if they run into nails or knots. Be prepared for bit binding situations. To reduce the chance of bit binding:
•Use sharp bits. Sharp bits are less likely to bind when drilling.
•Use the proper bit for the job. There are bits that are designed for specific purposes.
•Use caution when drilling pitchy, knotty, wet or warped material or when drilling in material that may contain nails.
ACCESSORIES
WARNING To reduce the risk of injury, always unplug the tool before attaching or removing accessories. Use only specifically recommended accessories. Others may be hazardous.
For a complete listing of accessories refer to your MILWAUKEE Electric Tool catalog or go
MAINTENANCE
WARNING To reduce the risk of injury, always unplug your tool before performing any maintenance. Never disas- semble the tool or try to do any rewiring on the tool’s electrical system. Contact a MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular maintenance program. Before use, examine the general condition of your tool. Inspect guards, switches, tool cord set and extension cord for damage. Check for loose screws, misalignment, binding of moving parts, improper mounting, bro- ken parts and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, turn the tool off immediately and have the problem corrected before further use. Do not use a damaged tool. Tag damaged tools “DO NOT USE” until repaired (see “Repairs”).
Under normal conditions, relubrication is not neces- sary until the motor brushes need to be replaced. After six months to one year, depending on use, return your tool to the nearest MILWAUKEE service facility for the following:
•Lubrication
•Brush inspection and replacement
•Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.)
•Electrical inspection (switch, cord, armature, etc.)
•Testing to assure proper mechanical and electri- cal operation
WARNING To reduce the risk of injury, electric shock and damage to the tool, never immerse your tool in liquid or allow a liquid to flow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool handles clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean your tool since certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these include: gasoline, turpentine, lacquer thin- ner, paint thinner, chlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use flammable or combustible solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the nearest service center.
