5.2 Hydraulic Valve
The WXR Series wood splitters are equipped with 2X2–
Speed FIREBOLT technology. The FIREBOLT system consists of
a two-stage hydraulic pump and a regenerative control valve.
Two extend speeds provide either High Speed (2) or High
Power (1). High extend speed is achieved by cycling oil from the
rod-end of the cylinder through the control valve and reusing it
at the base of the cylinder, instead of returning to tank.
When retracting the cylinder, a detent holds the lever until the
wedge / push block fully returns, providing hands-free operation.

STOP Position
• STOP is the valve's neutral position. The wedge or push
block stop moving when the valve lever is moved to this
position. The valve lever spring-returns to STOP when
released from either extend position, or auto-retract.
• The valve lever can be moved to STOP at any time.
High Speed Position (2)
• Pushing the lever forward to High Speed position (2) at the
first detent provides a higher cylinder extension speed. In
this position the cylinder extends at high speed, but lower
power.
• Releasing the lever returns it to STOP .
High Power Position (1)
• Push the control lever fully forward to High Power position
(1) for maximum power. The cylinder extends at a slower
speed but provides higher power to push the wedge or
push block through the wood for effective splitting.
• Releasing the lever returns it to STOP .
Retract Position
• Pull the lever fully backwards to retract the wedge / push
block. The valve detent holds the lever in retract allowing a
hands-free return cycle.
• The valve lever returns to STOP (neutral) when wedge /
push block is fully retracted.
• The lever can be moved out of Retract into STOP at any
time.
