Connecting the Hydraulic
Hoses
1. Stop the engine.
2. Move the auxiliary hydraulics lever forward,
backward, and back to neutral to relieve pressure
at the hydraulic couplers.
IMPORTANT: Ensure that all foreign matter
is cleaned from the hydraulic connections
before making connections.
3. Remove the protective covers from the hydraulic
couplers on the traction unit. Connect the covers
together to prevent contamination during
operation.
4. Ensure that the hydraulic hoses on the breaker
are routed through the loop on the top of the
mount plate.
5. Slide the collar back on the hydraulic coupler
and connect the attachment couplers to the
machine couplers.
6. Confirm that the connection is secure by pulling
on the hoses.
Removing the Breaker from the
T raction Unit
1. Start the engine and lower the breaker to the
ground or onto a trailer.
2. Stop the engine.
3. Disengage the attachment lock pins by turning
them to the outside.
4. Move the auxiliary hydraulics lever forward,
backward, and back to neutral to relieve pressure
at the hydraulic couplers.
5. Slide the collar back on the hydraulic couplers
and disconnect them.
IMPORTANT: Connect the attachment hoses
together to prevent hydraulic system
contamination during storage.
POTENTIAL HAZARD
•Hydraulic fluid escaping under pressure
can penetrate skin and cause injury.
WHAT CAN HAPPEN
•Fluid accidentally injected into the skin
must be surgically removed within a few
hours by a doctor familiar with this form of
injury or gangrene may result.
HOW TO AV
OID THE HAZARD
•Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
•Use cardboard or paper to find hydraulic
leaks, never use your hands.
6. Install the protective covers onto the hydraulic
couplers on the traction unit.
7. Start the engine, tilt the mount plate forward,
and back the traction unit away from the breaker.

Operation
Operating T ips
•Always use full throttle (maximum engine
speed) when breaking.
•Use low range (turtle position) on the speed
selector for best performance and smoothest
operation.
•Adjust the flow divider valve to approximately
the 10 o’clock position.
•Place the bit within 6 to 18 inches of the edge of
the material to be broken with the breaker angled
slightly towards the edge (Fig. 4).
m–4249
Figure 4
•If the bit is positioned too far from the edge of
the material the energy may be absorbed by the
material without breaking it. If the material has
not cracked after 15 to 20 seconds, stop the
breaker and move the bit to a different location.
IMPORTANT: Continuous penetration in the
same location for long periods of time will
create high temperatures at the tip of the bit.
This could cause the bit to lose its temper and
mushroom under impact, destroying the bit.
•When breaking, always apply downward
pressure with the loader arms until the front
wheels raise off of the ground a few inches
(Fig. 4). Maintain this pressure as the bit works
its way into the material being broken.
•Do not move the auxiliary hydraulics lever to
engage the breaker unless the bit is on the
ground and downward pressure is applied.
•Do not bind the bit in the material being cut.
Binding of the bit can cause the bit to bend or
wear out prematurely. Ensure that all force
applied to the breaker is inline with the bit, not
side to side or front to back. This will require
frequent adjustments in the positioning of the
traction unit.
•Listen to the sound of the breaker when is is
operating. The sound will be different when
there is adequate downward pressure than when
not enough pressure is being applied.
•Many materials do not respond well to continued
hammering in one place. Move the the breaker
each time that it penetrates the material without
breaking it. When you move the breaker to a
new location, move it in a line parallel to the
edge of the material, about 3 inches from the
previous hole. This will score the material and if
done repeatedly, break off a large piece of the
material (Fig. 5).

Operation

m–4250
Figure 5
IMPORTANT: Never pry with the bit.
•If you are breaking rebar reinforced concrete, use
a chisel bit in the breaker to cut through the
rebars in the concrete. The rebar can also be cut
with a torch.
IMPORTANT: Do not use the breaker in or
under water.
Breaking a V ertical Surface
Converting the Breaker
1. Tilt the breaker as far forward as possible and
lower it until the tip is resting on the ground.
2. Remove the click pin securing the front
mounting pin (Fig. 6).
3. Drive the front mounting pin out of the breaker
(Fig. 6).
4. Lower the loader arms until the holes in the
breaker align with the upper holes in the mount
(Fig. 6).
5. Drive the front mounting pin through the upper
holes and secure it with the click pin (Fig. 6).

Operating Tips for Vertical Surfaces
•Position the bit on the vertical surface in the
same manner as you would position it on a
horizontal surface.
•Maintain pressure on the bit by driving the
traction unit forward into the vertical surface
while operating the breaker.

Greasing the Bit
Service Interval/Specification
Grease the bit before each use and then after every 1
to 2 hours of operation. Grease it immediately after
washing.
Grease Type: General-purpose grease, certified NGLI
number 1 or 2.
How to Grease
1. Tilt the breaker so that it is vertical, then lower it
to the ground so that the bit is pushed up into the
breaker as far as possible.
IMPORTANT: Failure to push the bit up into
the breaker before greasing will allow the
grease to fill the space between the top of the
bit and the breaker piston. When you next
use the breaker, the piston will pr
essurize this
grease and cause seal damage.
2. Stop the engine and remove the key.
