The recommended hose size is .500 inch/12 mm ID up to 50 ft/15 m long and .625 inch/16 mm ID minimum up to
100 ft/30 m.
PRE-OPERATION PROCEDURES
CHECK POWER SOURCE
1. Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of 7–9
GPM/26–34 LPM at 2000 psi/140 bar or 5–6 GPM /18–22 LPM at 1500–2000 psi /105–140 bar. Proper flow and
pressure maintain proper tool speed.
2. Make certain the hydraulic power source
is equipped with a relief valve set to open
at 2250 psi/155 bar maximum.
INSTALL TOOL BIT - FIG. 2
1. Rotate the latch on the breaker foot
downward (pointing away from the tool).
2. Insert the tool bit into the foot and pull the
latch up to lock the tool bit in place.
Note: Never use the tool if the bit is not
locked in the tool retainer.
CONNECT HOSES
1. Wipe all hose couplers with a clean, lint-
free cloth before making connections.
2. Connect the hoses from the hydraulic
power source to the tool fittings or quick
disconnects. It is a good practice to
connect return hoses first and disconnect
them last to minimize or avoid trapped pressure within the tool.
3. Observe flow indicators stamped on hose couplers to ensure that fluid flow is in the proper direction. The female
coupler on the tool hose is the inlet coupler.
4. Move the hydraulic circuit control valve to the ON position to operate the tool.
Note: If uncoupled hoses are left in the sun, pressure increase within the hoses may make them difficult
to connect. When possible, connect the free ends of the
hoses together.
OPERATION PROCEDURES - FIG. 3
1. Observe all safety precautions.
2. Install the appropriate tool bit for the job.
3. Wrap your hands around the handles and stand in back of
the tool, using your leg against the snap-on filler for tool
stability.
Note: Hold the tool correctly and be ready to counteract
normal or sudden movements. Have both hands available.
4. Place the breaker bit on the material to be broken, at a 90°
angle. Apply down pressure.
5. Flip the trigger lock (CE models only).
6. Slowly squeeze the trigger to start breaking. Squeeze hard-
er for fast speed operation.
