They have a be used in either of the 120 volt out- Fig. B Fig. C lets shown in Figures B and C. Grounded tools require a three wire extension cord. Double insulated tools can use either a two or three wire extension cord. 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. Refer to the table shown to determine the required minimum wire size. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. When using more than one extension cord to make up the total length, be sure each cord contains at least the minimum wire size required. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum wire size. Guidelines for Using Extension Cords • If you are using an extension cord outdoors, be sure it is marked with the suffix “W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use. • Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it. • Protect your extension cords from sharp objects, excessive heat and damp or wet areas.

Use only specifically recommended accessories. Others may be hazardous. WARNING! Adjusting the Side Handle To reduce the risk of injury, always use a side handle when using this tool. Always brace or hold securely. WARNING! TOOL ASSEMBLY To reduce the risk of injury, always unplug tool before attaching or removing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous. WARNING! Adjusting the Side Handle To reduce the risk of injury, always use a side handle when using this tool. Always brace or hold securely. WARNING! 1. Loosen the side handle slightly by unscrewing it counterclockwise. Installing Bits (Fig. 1) 2. Rotate the side handle to the required angle. This tool is designed with a universal drive system that accepts SDS, SDS Plus and Hilti TE-C bits. Always clean and lubricate the shank of the 3. Tighten the side handle securely. bit before installing it into your tool to help prevent heat build-up and protect the bit shank from wear due to abrasive concrete dust. Setting the Depth Gauge (Fig. 2 & 3) Fig. 1 Recesses in bit shank Marks on chuck collar 1. Pull the chuck collar back toward the tool. 2. Line up the recesses on the shank of the bit with the marks on the chuck collar as shown (Fig. 1). Insert the bit into the spindle as far as possible. 3. Release the chuck collar, locking the bit into position. Rotate the bit slightly to be sure it is locked securely. 4. To remove the bit, pull the chuck collar back toward the tool and remove the bit. Fig. 2 Depth gauge Depth gauge clamp 1.To adjust the depth gauge, flip the depth gauge clamp up (Fig. 2). 2.Slide the depth gauge rod backward or forward until it is set for the desired depth. The drilling depth is the distance between the tip of the bit and the tip of the depth gauge rod (Fig. 3). Fig. 3 Drilling Depth 3. Press the clamp down to secure the depth gauge. page 6 OPERATION To reduce the risk of injury, wear safety goggles or glasses with side shields. WARNING! Selecting Action (Fig. 4) MILWAUKEE Hawk Rotary Hammers have two settings: drilling or hammering with rotation. Drill Hammer Arrow Fig. 4 Hammer/ Drill Collar Chuck Collar 1. For drilling, turn the hammer/drill collar so that the twist drill symbol lines up with the arrow on the chuck collar. 2. For hammering with rotation, turn the hammer/drill collar so that the hammer symbol lines up with the arrow on the chuck collar. NOTE: To engage the hammering mechanism, maintain pressure on the bit. When pressure on the bit is released, the hammering action will stop. Using the Forward/Reverse Switch (Fig. 5) Fig. 5 Forward/Reverse switch Forward Reverse 1. For forward (clockwise) rotation, push the forward/reverse switch to the left. 2. For reverse (counterclockwise) rotation, push the forward/reverse switch to the right. An interlock prevents switching to reverse while pulling the trigger. To prevent damage to the gears and motor, allow the tool to coast to a full stop before reversing.
