EXTENSION CORDS
TOOL ASSEMBLY
Grounded tools require a three wire exten- sion 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 ex- ample, 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 out- doors, be sure it is marked with the suffix
•Be sure your extension cord is prop- erly 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.

WARNING
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.
Installing Bits (Fig. 1)
This tool is designed with a universal drive system that accepts SDS, SDS Plus and Hilti
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. Then, 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, twist bit slightly and remove.
WARNING
To reduce the risk of injury, always use a side handle when using this tool. Always brace or hold securely.
Adjusting the Depth Gauge (Fig. 2)

Drilling
Depth
1.To adjust the position of the depth rod, loosen the side handle.
2.Slide the depth gauge rod backward or forward until it is set for the desired depth.
NOTE: The drilling depth is the distance between the tip of the bit and the tip of the depth gauge rod.
3.Tighten the side handle securely.
