SECURING THE TOOL BIT
1. The tool retainer is shipped installed in the breaker
(see parts illustration).
2. Drive out the tool retainer using a punch and
hammer.
3. Grease the top area of the tool bit as shown in
Figure 1.
4. Install the tool bit making sure the notch is aligned
with the lower body retainer pin hole.
5. Install the tool retainer.
Always wear eye protection when installing or
removing the tool retaining pin.
LOW TEMPERATURE WARM-UP
PROCEDURE
1. After starting the carrier, warm-up the hydraulic
system at engine idle until hydraulic lines are warm
to the touch.
2. With the carrier at idle and the breaker suspended
in the air or with minimal down pressure, turn
on the breaker to gradually warm up its internal
components.
3. When the hydraulic system and breaker are warm,
proceed with operation.
LONG TERM STORAGE
1. Remove the tool bit, clean the tool stop and the
lower bushing. Thoroughly coat the surfaces of the
tool stop and the lower bushing with grease.
2. If hoses are attached to the breaker, install plugs
on the hose ends. If hoses are removed from the
breaker, install plugs on the hose ends and install
plugs in the breaker IN and OUT ports.
3. Store the breaker in a vertical position. Do not store
the breaker horizontally for extended periods.
OPERATING A BREAKER
PREPARATION FOR USE
Read the section in this manual titled Pre-Operation
Procedures before operating a breaker. Failure to follow
the preparation instructions can result in severe damage
to the breaker and carrier, and void the warranties of
both.
POSITIONING THE CARRIER
SKIDSTEER LOADERS
With the breaker tool in place on the material to be
worked, position the skidsteer loader arms and the
breaker bracket so the breaker is almost vertical and the
front tires of the skidsteer are off of the ground.
Keep lowering the loader arms as the tool penetrates
the work material so the skidsteer weight stays on the
tool. The breaker is more efficient when adequate down
force is applied.
