Operation

For use as a Hammer Drill:

CAUTION: Use only impact grade SDS-Plus bits, designed for SDS-Plus hammer drills. Standard bits will not be properly held by this Chuck, and may break under the force created by this tool. SDS-Plus impact grade bits are available from Harbor Freight Tools.

1.The Auxiliary Handle must be installed for additional stability when Hammer Drilling. Always use both hands to hold this tool during hammer drill operation. To install Auxiliary Handle, slide the Auxiliary Handle Assembly (32) over the Front Housing (24). Tighten the screw in the Handle Assemble to lock in place. Adjust the length of the

Depth Gauge Rod to stop the drilling process when the

correct hole depth is reached. Tighten the Depth Gauge Rod in place by tightening the screw in the Auxiliary Handle Assembly.

2.This tool has three settings, Drill Only, Hammer Only and Hammer Drill. Select

the proper setting for the work you will do. Be sure the tool has come to a

complete stop before moving the selector to another setting. Move the Function Selector to the Hammer Drill setting. Please see picture on page 9 for reference. This setting will allow the drill to hammer as well as turn.

3.Press the Forward-Reverse Switch (61) to the right for forward drilling, press it to the left for reverse drilling.

4.The speed of the tool is controlled by squeezing the Trigger (60). Progressively increase or decrease pressure on theTrigger to make the tool operate faster or slower.

5.The Hammer Drill is best suited for drilling into hard materials such as concrete or masonry. Select an appropriate size and type SDS-Plus hammer drill bit (not included). Insert it onto the Chuck and tighten securely. See instructions on page 7 for inserting SDS-Plus drill bits.

Warning: Always wear ANSI approved safety glasses and full face shield

when hammer drilling. Caution: Always check around and behind the area being drilled to prevent drilling into wires, pipes or causing other unintentional property damage. Always use 2 hands when using this tool.
