for tethering or securing the tool to a person or
object during use. DO NOT suspend tool overhead or
suspend objects from the ultilty hook.

use only the screw 14 that is provided. Be sure to securely
tighten the screw.

Side Handle and Depth Rod (Fig. A, 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 1 clamps to the front of the gear case and may
be rotated 360˚ to permit right‑ or left‑hand use.
The side handle clamps to the collar
13 and has 12 tightening
locations. The side handle can be tightened by rotating the
grip of the side handle clockwise. The side handle must be
tightened sufficiently to resist the twisting action of the tool if
the accessory bind or stall. Be sure you moved the side handle
against the end of the collar end to have the clamping piece
fully engaged.
To Adjust the Depth Rod (Fig. A)
Loosen the side handle
1
and move the depth rod
2
so that
the distance between the end of the rod and the end of the bit
equals the desired drilling depth. When drilling with depth rod,
stop when end of rod reaches surface of material.
Electronic Overload Protection
If the drill bit becomes jammed, the power to the drill spindle
will be interrupted by the activation of the electronic overload
protection. To reactivate the power to the drive spindle, the
tool's trigger should be released and then depressed. Due to the
resulting forces, always hold the tool with both hands and take
a firm stance.
To actuate the fuel gauge, press and hold the fuel gauge
button
12 . A combination of the three green LED lights will
illuminate designating the level of charge left. When the level
of charge in the battery is below the usable limit, the fuel gauge
will not illuminate and the battery will need to be recharged.
nOTE: The fuel gauge is only an indication of the charge left on
the battery pack. It does not indicate tool functionality and is
subject to variation based on product components, temperature
and end‑user application.
