Handling

1. Preparation Before starting
(1) Check the level of hydraulic oil and replenish it if necessary. Be sure
to use the same kind of hydraulic oil.
(2) Confirm that the stop valves are fully open.
(3) Check that the screwed connections of the hoses, bolts and nuts are
tight. Retighten these if loose.
(4) Grease the shank part of the chisel.
(With down pressure applied to chisel, apply Okada Chisel Paste to
Shank Bushing until it squeezes out from the working tool or chisel set
pin area.)
(5) Run the excavator for about 10 minutes to warm up the machine.
Start operation only after the oil temperature has risen.

2. Break-in
For the first one hour of the use of your breaker, position the chisel vertically onto the material to be broken,
apply pressure downwards and do break-in at half engine speed in order to break in of parts.
Note: Do not tilt the chisel during break-in period.
3. Precautions during operation

broken so that the crawler or the front
wheels of the tires float slightly, then start
hammering by applying pressure.
●

hammering immediately.
● Avoid using the chisel as a lever or ripper
and hitting any object against the chisel.
Caution: Force prying the material with
the chisel may lead to breakage of the
chisel.
● When the chisel no longer goes into the
material, change the hammering position.
Do not hammer the material continuously
for more than 30 seconds at one spot.
Otherwise, not only the chisel burns but
also oil temperature rises abnormally, and
these lead to trouble.
