Locking Trigger (Fig. 2.)
The lock button holds the trigger in the ON position for continuous full
speed use.

Using Forward/Reverse Switch (Fig. 3)
1. For forward (clockwise) rotation, push the forward/reverse switch
to the right.
2. For reverse (counterclockwise) rotation, push the forward/reverse

Using the Shift Mechanism (Fig. 4)
MILWAUKEE
Hammer-Drills are designed for two operating modes:
drilling with hammering action and drilling only.
1. To use the hammer-drilling mode, rotate the knurled shift collar until
the hammer symbol appears at the top center of the collar. Apply
pressure to the bit to engage the hammering mechanism.
2. To use the drilling only mode, rotate the knurled shift collar until the
drill symbol appears at the top center of the collar.
Auxiliary Side Handle and Depth Gauge
A side handle is furnished to provide maximum control of the tool. It may
be threaded into either side of the gear case where it serves to lock the
depth gauge in position by clamping the rod between the handle flange
and the groove in the gear case. To change the setting, loosen the
handle slightly, reposition the rod and retighten the handle.
Installing Bits Into Keyed Chucks (Fig. 5)
MILWAUKEE
Hammer-Drills are equipped with an industrial, key-type
geared chuck.
Fig. 5
Tighten
Loosen
1. Open the chuck jaws wide enough to insert the bit. Be sure the bit
shank and chuck jaws are clean. Dirt particles may prevent the bit
from lining up properly.
2. When using drill bits, insert the bit into the chuck. Center the bit in the
chuck jaws and lift it about 1/16" off of the bottom. Then, tighten the
chuck jaws by hand to align the bit.
3. Place the chuck key in each of the three holes in the chuck, turning
it counterclockwise as shown. Tighten securely.
Dust Shield
A dust shield is provided to keep abrasive dust out of the mechanism and
to prevent grease contamination. Always operate the Hammer-Drill with
the dust shield in place.

WARNING!
To reduce the risk of injury, wear safety goggles or glasses
with side shields. Unplug the tool before changing accesso-
ries or making adjustments.
