Figures 4 and 5 show examples of a Hole Hawg® properly braced for forward rotation. A. Forward (clockwise) rotation B. Reaction C. Brace drill with pipe handle here D. Brace drill with motor housing here If the bit binds, the pipe handle or the motor housing braced against the stud will hold the drill in position. Bracing for reverse rotation Fig. 6 C B A Fig. 7 D B A When drilling in reverse, the bit will rotate in a counterclockwise direction. If the bit binds in the hole, the bit will come to a sudden stop and the drill will suddenly react in a clockwise direction. Figures 6 and 7 show examples of the Hole Hawg® properly braced for reverse rotation. A. Reverse (counterclockwise) rotation B. Reaction C. Brace drill with pipe handle here D. Brace drill with motor housing here If the bit binds, the pipe handle or the motor housing braced against the stud will hold the drill in position. Shifting Speeds (Fig. 8) Cat. No. 1675-1 has a gear shift lever on the right side of the gear case. The high setting (1200 RPM HI) is the low torque setting and is designed for driving Selfeed bits 1-3/8" in diameter and smaller. The low setting (300 RPM LO) is the high torque setting and is designed for driving Selfeed bits 1-1/2" in diameter and larger. Reversing (Fig. 9) Fig. 9 Fig. 8 Chuck Removal To remove the chuck from the drill: 1. Unplug tool. warning To reduce the risk of injury, always wear eye protection. Drilling Before drilling, clamp down the material securely. A poorly secured piece of material may result in personal injury or inaccurate drilling. When drilling in light gauge metal or wood, use a wooden block to back up the material to prevent damage to the workpiece. Mark the center of the hole to be drilled with a center punch to give the bit a start and to prevent it from "walking." Lubricate the drill bit with cutting oil when drilling iron or steel. Use a coolant when drilling nonferrous metals such as copper, brass or aluminum. To start a selfeed bit, run the threaded feed screw into the work by flicking the trigger switch, permitting the bit to coast until the teeth contact the work surface. Align the bit properly before proceeding. This will reduce cocking and jamming when starting. To reduce jamming on breakthrough, decrease the drilling pressure when the feed screw point breaks through the workpiece. Proceed with steady, even pressure. 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, broken 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 necessary 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 warning To reduce the risk of injury, always unplug your tool before performing any maintenance. Never disassemble the tool or try to do any rewiring on the tool's electrical system. Contact amilwaukee service facility for ALL repairs. 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. mainTenance 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 thinner, 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. Shifting Speeds (Fig. 8) Cat.
