What is a BR87 Hydraulic Breaker?
BR87 is a hydraulic breaker for use in the 90 lbs. weight class. Its highly
productive in utility construction, street maintenance, repair of water and
gas mains, and general contracting jobs. BR87 requires an external hydraulic
power source capable of supplying 7-9 GPM.

Tool Setup - Detail B
Do not install or change tool accessories while the
hydraulic power source is connected. Accidental
engagement of the tool can cause serious injury.
Disconnect the hydraulic power source before installing
or changing accessories.
1. Disconnect the tool from the hydraulic power source.
Install the Breaker Bit
The tool bit can get extremely hot during operation.
Always wear gloves when installing bits. Hot bits can
cause burns.
2. Unlock the breaker foot latch.
3. Insert the tool bit and lock the latch. Never use BR87 unless the tool bit
is locked in the retainer.
Note: Never use a blunt tool bit as they cause more vibration.
Connect to a Hydraulic Power Source
4. Using a calibrated flow and pressure gauge, check the output of the
hydraulic power source. Ensure it matches the flow and pressure in
“Specifications” on page 9. Hydraulic fluid must be 50°F or above.
Preheat if necessary.
5. Ensure that the hydraulic power source is equipped with a relief valve
set to open at the maximum relief pressure. See “Specifications” on
page 9.
6. Wipe hose couplers with a clean, lint free cloth.
7. Connect the return hose to the tool port marked “Out”.
8. Connect the pressure hose to the tool port marked “In”.
9. Ensure couplers are undamaged, properly connected and are tight.
10. Power up the hydraulic power source.
Tool Operation - Detail C
Always hold tool with both hands to maximize control.
Apply proper down pressure and maintain proper
footing at all times.
1. Wrap your hands around the handles. Stand in back of the tool, using
your leg against the snap-on filler for stability.
Note: Hold the tool correctly and be ready to counteract normal or sudden
movements. Have both hands available.
2. Place the breaker bit on the material to be broken, at a 90° angle.
Apply down pressure.
3. Push the trigger lock button in towards the handle (CE models only).
4. Slowly squeeze the trigger to start breaking. Squeeze harder for fast
speed operation.
5. When starting, break until the tool bit breaks through, then reposition
the bit. Do not use the tool bit as a lever to move material.
Note: Never cool a hot tool bit in water. Tools can become brittle and fail.
6. Continue breaking around the original hole, in 2 inch sized bites.
7. Release trigger to stop the tool.
Note: If you encounter a breakdown or the tool stops for any reason, release
the trigger and power down the hydraulic power source.
Tool Maintenance
Do not perform maintenance on the tool while the
hydraulic power source is connected. Accidental
engagement of the tool can cause serious injury.
Disconnect the hydraulic power source before servicing.
