Operating Instructions
or clamp. Do not place hands on
the black cylinder or spring retainer
when operating the tool.
General Safety
(Continued)
The spring
retainer
must be
used to hold the chisel in
place. Personal injury can
occur if the chisel is not secure.
15. Risk of electrical shock: this tool is
conductive. Do not hammer into
walls containing live electrical
wiring.
Assembly
SYSTEM SETUP
Using fittings or air hoses which are
too small can create a pressure drop
which will result in a loss of power in
the tool.
NOTE: Do not install a quick coupler
set between the tool and whip hose.
Do not misuse this
product. Excessive
exposure to
vibration, work in awk-ward positions
and repetitive work motions can cause
injury to hands and arms. Stop using
any tool if discomfort, numbness,
tingling or pain occur, and consult a
physician.
Never carry a tool
by the hose or pull
the hose to move
the tool or a compressor. Keep hoses
away from heat, oil and sharp edges.
Replace any hose that is damaged,
weak or worn.
Pre-Operation
Air tools require lubrication through-
out the life of the tool. Proper
lubrication is the owner's
responsibility. Use airtool
oil to lubricate, clean and
inhibit rust in one step.
Failure to lubricate and
maintain the air tool properly will
dramatically shorten the life of the tool
and will void the warranty.
This air
tool requires
lubrication before

initial use and before and after each
additional use.
AIR PISTON LUBRICATION
The air piston must be lubricated
daily. An air piston cannot be oiled
too often.
Disconnect the
chisel/hammer from
the air supply
before lubricating.
1. Turn the chisel/hammer upside
down.
2. While pulling the trigger, pour a
teaspoon of oil in the air inlet.
Cover exhaust port
with a towel
before applying air
pressure. Oil will discharge through
the exhaust port during the first few
seconds of operation after an airtool
has been lubricated. Failure to cover
exhaust port can result in serious
injury.
3. Connect the chisel/hammer to the
air supply and cover the exhaust
port with a towel. Run the chisel/
hammer for 7 to 10 seconds. Oil will
discharge from the exhaust port
when air pressure is applied. If the
piston does not cycle, install a bit
into the spring retainer. Be careful
not to allow the towel to catch in
the spring retainer.

SPRING RETAINER
The spring retainer holds the hammer
in place. The retainer must be securely
attached (See Figure 1). The retainer
is a normal wear item and should
be replaced when worn. Campbell
Hausfeld offers item number MP2896,
a replacement hammer spring, for this
tool. The retainer unscrews for easy
hammer insertion.
QUICK CONNECT RETAINER
used to hold the hammer in place.
Personal injury can occur if the hammer
is not secure.
The quick connect retainer holds the
hammer in place. The retainer must be
securely attached and the three set
screws must be tightened completely
using a hex wrench (See Figure 2). The
retainer pulls back for easy hammer
insertion and snaps forward to hold
the hammer. The retainer is a normal
wear item and should be replaced
when worn.

REGULATOR
Some air hammers are equipped with
a built-in air regulator to reduce the
blow rate. It is located next to the air
inlet. Turn the knob counter-clockwise
for the fully open, highest speed.
Gradually turn the knob clockwise to
reduce the speed (See Figure 3).
