Tool Bushings

Align tool with the piston.

Provide contact surfaces with tool.

Field replaceable for better serviceability.

UpperLower

Tool Retainer PinsPrevents tool from falling out.

Absorbs partial impact forces on idle strokes.

Transfers impact force to front head on idle strokes.

Thrust RingAbsorbs shock load from tool.

Positions piston for start ofhammer operating cycle.

Positions tool for correct contactwith piston.

Tie Rod AssembliesAssembled as matched pairs.

Hold hammer assembly together.

Absorbs partial impact loads of idle strokes.

Main Distributor ValveDirects oil flow for piston movement.

Connects piston shoulder totank on upward stroke.

Connects piston shoulder to inletpressure on downward stroke.

Pressure Control ValveActs as timing mechanismfor hammer operating cycle.

Holds return oil path closed untilaccumulator is fully charged.

Opens return oil path by operatingpressure signal.

Isolates return line from firingstroke by closing port.Inlet Outlet Outlet

Check ValveIsolates supply line from internal pressure spikes.

Absorbs internal pulsation from firing cycle.

Maintains oil volume inside hammer.

AccumulatorStores energy for the impactstroke.

Pushes oil acting on pistonduring impact stroke.

Dampens pressure pulsations.

Accumulator - Nitrogen Pre ChargePositions membrane in accumulator.

Stores energy for piston impact.

Absorbs internal pressure spikes .
