Operating Tips
•
Wear eye, ear, and breathing protection while using the
breaker.
•
If your traction unit is a TX series traction unit, use 3/4
throttle when breaking to prevent damage to the breaker.
•
If you have a traction unit other than a TX series traction
unit, use full throttle (maximum engine speed), low range
(turtle position) on the speed-selector lever, and adjust
the flow-divider valve to approximately the 10 o’clock
position.
•
Place the bit within 15 to 46 cm (6 to 18 inches) of the
edge of the material to be broken, and angle the breaker
slightly toward the edge (
Figure 4
•
If the bit is positioned too far from the edge of the
material, the material may absorb the energy and not
break. If the material has not cracked after 15 to 20
seconds, stop the breaker and move the bit to a different
location.
•
When breaking, always apply downward pressure with the
loader arms until the front of the traction unit raises off
the ground a few inches (
). 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 requires
frequent adjustments in the positioning of the traction
unit.
•
Listen to the sound of the breaker when is operating. The
sound changes when downward pressure decreases. If the
downward pressure from the unit is too weak, you will
hear metallic strokes from the hammer as it incorrectly
strikes the bit.
•
Excessive downward pressure produces strong vibrations
in the unit.
•
Many materials do not respond well to continuous
hammering in one place. Each time that the breaker
penetrates the material without breaking it, move it to a
new location in a line parallel to the edge of the material,
about 7.6 cm (3 inches) from the previous hole. This
scores the material and if done repeatedly, breaks off a
large piece of the material (Fig. 3).

•
If you are breaking rebar-reinforced concrete, use a
chisel bit in the breaker to cut through the rebars in the
concrete. You can also cut the rebar with a torch.
