English gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord. Minimum Gauge for Cord Sets Volts Total Length of Cord in Feet (meters) 120 V 25 (7.6) 50 (15.2) 100 (30.5) 150 (45.7) 240 V 50 (15.2) 100 (30.5) 200 (61.0) 300 (91.4) Ampere Rating More Not Than More American Wire Gauge Than 0 6 18 16 16 14 6 10 18 16 14 12 10 12 16 16 14 12 12 16 14 12 Not Recommended The label on your tool may include the following symbols.

Voltage decrease of more than 10% will cause loss of power and overheating. DeWALT tools are factory tested; if this tool does not operate, check power supply. COMPONENTS (FIG. A) WARNING: Never modify the power tool or any part of it. Damage or personal injury could result. Refer to Figure A at the beginning of this manual for a complete list of components. Intended Use Your heavy-duty rotary hammers is designed for professional concrete drilling and chiseling applications. DO NOT use under wet conditions or in presence of flammable liquids or gases. Your heavy-duty rotary hammer is a professional power tools. DO NOT let children come into contact with the tool. Supervision is required when inexperienced operators use this tool. ASSEMBLY AND ADJUSTMENTS WARNING: To reduce the risk of serious personal injury, turn unit off and disconnect it from power source before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury. Side Handle and Depth Rod (Fig. B, C) WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with the side handle properly installed. Failure to do so may result in the side handle slipping during tool operation and subsequent loss of control. Hold tool with both hands to maximize control. The side handle 5 clamps to the front of the gear case and may be rotated 360˚ to permit right- or left-hand use. Mounting the Straight Side Handle (Fig. B) 1. Widen the ring opening of the side handle 5 by rotating it counter clockwise. 2. Place the assembly onto the putting the nose of the tool through the steel ring 12 and onto the collar 11 past the bit holder and sleeve. 3. Rotate the side handle assembly to the desired position. For hammerdrilling horizontally with a heavy drill bit, place the side handle assembly at an angle of approximately 20° to the tool for optimum control. 4. Lock the side handle mounting assembly in place by securely tightening the handle 5 rotating it clockwise so that the assembly will not rotate. Fig. B 12 11 5 4
