b. If possible, avoid operating the paving breaker with air pressure greater than 90 psi.
c. Hold the paving breaker handles firmly and plant feet solidly during operation.
d. Always turn off the paving breaker before laying it down.
e. Always detach the air hose from the air connection when stopping operations for any length of time.
134. Operation
a. Attach the tool to be used to the paving breaker. The moil point, chisel and tamping rod are inserted up into the
breaker and are locked in with the retainer latch
(fig. 62). When the sheeting driver (fig. 63) is to be used, the chuck housing (fig. 62) and tappet seat must be removed
and the sheeting driver installed.
b. Fill the paving breaker oil reservoir with oil (par. 135a).
c. Blow out the air hose and connect it to the air connection of the paving breaker.
d. Operate the paving breaker at low speed for a few moments to permit even distribution of oil to all working parts.
135. Servicing
a. Lubrication. It is vitally important that the paving breaker (fig. 62) and sheeting driver (fig. 63) be well lubricated
at all times. Always fill the oil reservoir before starting operations, and check the oil supply frequently, refilling whenever
necessary. Wipe off the oil plugs before removing them to fill the oil reservoirs. Below 32 F. use engine oil, OE--10 or
OHA; above 32 F., use OE 30.
b. Preparing for Storage. To prevent the internal parts of the paving breaker (fig. 62) and sheeting driver (fig. 63)
from rusting while in storage, the following procedure is recommended.
(1) Flush the paving breaker and sheeting driver with cleaning solvent to remove grit, dirt and other foreign
matter.
(2) Flush the paving breaker and sheeting driver with light machine oil to lubricate internal parts.
(3) Wedge a cloth plug into the air connection and exhaust openings of the paving breaker to prevent dust from
entering while the tool is in storage. Wedge a cloth plug into the open end of the housing on the sheeting
driver for the same reason.
(4) Store the paving breaker and sheeting driver in its appropriate place in the engine side tool box.
