OPERATION

Accessory Installation

Always turn off the air supply and disconnect the air
supply hose before installing, removing or adjusting
any accessory on this tool or before performing any
maintenance on this tool. Failure to do so could result
in injury.
For Screw–on type Retainer No. DT9–22:
1. Grasp the Retainer (29) and unscrew from the Barrel
(22).
2. Insert the accessory through the Retainer Assembly
and install it on the tool. Screw the Retainer onto the
barrel until you feel the Retainer O–ring (28) drop
into the groove in the Retainer.
For Hitch Cutter Type Retainer No. DT9–273
1. Rotate Guard (39) to reveal accessory hole in Retainer
(38). Grasp the Retainer and unscrew from the
Barrel (22).
2. Insert the shank portion of the accessory through the
cutout in the side of the Hitchcutter. Screw the
Retainer onto the Barrel until you feel the Retainer
O–ring (28) drop into the groove in the Retainer.
For Latch type Retainer No. DT9–240
1. Operate the Latch (31) until it is 90 degrees to the
body of the tool and clicks into position.
2. Insert the accessory into the tool until the collar of the
accessory is past the Latch.
3. Operate the Latch until it is parallel to the tool and it
clicks into position.

OPERATING THE TOOL

1. Hold the Handle (and front of tool if working
horizontally) and press the point of the chisel firmly
into the workpiece.
2. Use a steady and well–balanced stance and squeeze
the Trigger (2).
3. Power is increased by depressing the Trigger.
4. Experience will indicate the correct amount of
pressure to the tool. Normally, the amount of pressure

is correct when the tool hits rhythmically, is
comfortable to hold and works efficiently.
Do not repair the tool at the work site. Always
take the tool to a repair shop. Never drag the tool
on the ground. The air port and other openings
will become clogged with dirt and debris.
Compressed air is dangerous. When blowing the
line clear of dirt, wear eye protection and keep the
air line directed toward a safe, clear area.
5. Always blow out the air line before using to clear the
line of dirt.
Do not operate the tool unless the chisel is against
the work since this will cause premature wear of
parts and reduce the vibration isolation properties
of the tool.
6. Always break material to the point of "give."
Cracking does not result in a complete break. Clear
away rubble as it is broken since uncleared rubble
blocks the point of "give."
7. Always take the right size "bite" with the tool. When
working new material, experiment to find the right
size "bite" required for breaking that material
efficiently.
If "bites" are too big, the operator will try to pry
with the tool. This could break the chisel. The tool
is designed for demolition, not prying. Always use
a pick for prying.
If "bites" are to small, the operator will be working
too slowly.
8. If the chisel or accessory should become stuck, do not
use excessive force or mechanical means on the tool
to pull out the chisel. Break out the stuck chisel with
a spare chisel or tool.
