Electrical Safety 4. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded. 5. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. 6. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way.
14. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the power tool in unexpected situations. 15. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Tool Use and Care 16. Use clamps (not included) or other practical ways to secure and support the workpiece to a stable platform.
SPECIFIC SAFETY RULES FOR THE HAMMER DRILL 1. Hold tool by insulated gripping surfaces when performing an operation where the cutting tools may contact hidden wiring or its own cord. Contact with a ”live” wire will make exposed metal parts of the tool “live” and shock the operator. 2. Maintain labels and nameplates on the Hammer Drill. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement. 3.
GROUNDING WARNING! Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualfified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use.
EXTENSION CORDS 1. Grounded tools require a three wire extension cord. Double Insulated tools (like this one) can use either a two or three wire extension cord. 2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.) 3. The smaller the gauge number of the wire, the greater the capacity of the cord.
SYMBOLOGY Table B UNPACKING When unpacking, check to make sure that all the parts are included. See Figure C.

ASSEMBLY INSTRUCTIONS 1. Insert the Auxiliary Handle (501) over the Housing (29) until it rests behind the Chuck (2). When required for exact depth drilling, insert the Depth Gauge (502) into the Auxiliary Handle clamp. See Figure D below. 2. Turn the Forward Handle for left or right-handed use, then securely tighten the wing nut until Auxiliary Handle cannot move.
Figure E Forward/Reverse Switch Switch On Locking Button Variable Speed Screw Trigger Switch (24) 3. Adjust the Variable Speed Screw for the desired (maximum) speed action when the Switch is pressed. 4. For precision depth drilling, loosen the Wing Nut securing the Auxiliary Handle (501), and slide the Depth Gauge (502) down, gauging the depth from the bit tip. Retighten the Wing Nut again. 5. Verify that the bit is securely locked in the Chuck (2). 6.
INSPECTION, MAINTENANCE, AND CLEANING Caution! Make sure the Power Switch of the Hammer Drill is in its “OFF” position and that the tool is unplugged from its electrical outlet before performing any inspection, maintenance, or cleaning procedures. 1. Before each use, inspect the general condition of the Hammer Drill. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring, and any other condition that may affect its safe operation.
