OPERATION

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.

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

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.

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 discon- nect 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 cou- pler.

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 in- crease within the hoses may make them difficult to connect. When possible, connect the free ends of the hoses together.

OPERATION PROCEDURES

1.Observe all safety precautions.

2.Install the appropriate tool bit for the job.

3.Place the bit firmly on the surface to be broken.

4.Squeeze the trigger to start the breaker. Adequate down pressure is very important. When the tool bit breaks through the obstruction or becomes bound, release the trigger and reposition the tool bit.

NOTE:

Partially depressing the trigger allows the tool to run at slow speed. Slow-speed operation permits easier starting of the tool bit into the work surface.

5.To start, break an opening (hole) in the center of the surface. After making a hole, break portions of the material into the original opening. For best produc- tivity, the breaking should be done around the origi- nal hole.

The size of the broken material will vary with the strength and thickness of the base material and the amount of any reinforcement wire or rebar.

Harder material or more reinforcing wire or rebar will require taking smaller bites. To determine the most effective bite, start with 2 in./50 mm or smaller bites.

Bites can then be gradually increased until the bro- ken piece becomes too large, requiring increased time to break off the piece.

Sticking of the tool bit occurs when too large a bite is being taken and the tool bit hammers into the mate- rial without the material fracturing. This causes the tool bit to become trapped in the surrounding mate- rial.

COLD WEATHER OPERATION

If the breaker is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluid, fluid temperature should be at or above 50 °F/10 °C (400 ssu/82 centistokes) be- fore use.

Damage to the hydraulic system or breaker can result from use with fluid that is too viscous or thick.
