Nameplate and Tags

• Flow and pressure sticker- Never exceed the flow
  and pressure levels
• Closed Center Sticker- Never use this tool on an
  open center circuit
• Safety Tag- Lists the safety instructions
• All tags and stickers must be legible at all time

5
Operation

• Store breaker in clean dry place
• Use breaker in appropriate size job
• Keep bits sharp
• Never operate tool without a bit
• Supply hoses have minimum working pressure 2500psi

• Tool repair should be done by qualified personnel
• Couplers must be kept clean
• Hydraulic circuit valve must be in OFF position
  when coupling or uncoupling hoses
• Make sure relief valves are installed on pressure
  side

6
Hydraulic System Requirements

• System should provide a flow of 7-9 gpm at
  operating pressure of 1500-2000psi
• System should not have more then 250psi
  backpressure measured at the tool

• System should have sufficient heat rejection
  capacity(max oil pressure140deg F)
• Hose size-.500 inch / 12mm up to 50 feet long
• Hose size -.625 inch / 12mm up to 100 feet long

7
Operating Instructions

• Hydraulic power source should develop flow of
  7-9gpm
• Relief valve set to 2100-2500psi
• Rotate latch on breaker foot downward
• Insert bit into foot and pull the latch up to
  lock the bit

• Wipe couplers with clean lint-free cloth
• Connect hoses from power source to tool fittings
• Connect return hose first and disconnect it last
  (avoids trapped pressure)
• Move circuit valve to ON position

8
Operating Instructions

• Choose the correct bit
• Place bit firmly on surface to be broken
• Squeeze trigger
• Partially depressing trigger allows tool to run
  at slower speed
• Breaking should be done in a spiral pattern
  around the original hole

• Harder and more reinforcing wire requires smaller
  bits (start with a 2bit)
• Sticking of the bit occurs when too large a bite
  is taken allowing the bit to drill into the
  material without fracturing it

9
Cold Weather Operation

• If used in cold weather you must preheat the
  hydraulic oil at low engine speed
• Oil temp should be at or above 50 deg F before use
