CONGRATULATIONS on the purchase of a HWP-120 Firewood
Processor. This Machine is designed and constructed to give you
many years of hassle-free operation. Please be sure to read and
understand this Operation/Safety Manual.
Skid Steer Requirements
The HWP-120 Firewood Processor is designed to operate
with a standard auxiliary hydraulic flow of 15.5 gallons per minute
(GPM). Flow over 15.5 GPM will exceed the motor capabilities
and cause premature failure. If your skid steer generates flows
greater than 15.5 GPM, you will want to run it at reduced throttle
setting to ensure the output DOES NOT EXCEED 15.5 GPM.
DO NOT RUN MACHINE ON HIGH FLOW!!!!
NOTE: Do NOT run the
machine without a case drain.
It will cause damage to the motor.
The processor is designed to operate with hydraulic pressures up
to 3000 PSI for optimum saw and splitter performance.
Reduction in performance and productivity will result from
pressures under 2850 PSI. It is important that the hydraulic
pressure DOES NOT EXCEED 3000 PSI or the valve body could
fail if operated at higher pressures.
In addition to standard pressure and return lines, the HWP-120
requires a low pressure case drain line. The chain saw motor
has a small amount of internal flow to provide lubrication to the
behind the motor’s shaft seal. If the oil has no place to go, it can
generate enough pressure to damage the shaft seal. It is not
acceptable to “tee” the case drain line into the Skid Steer’s
normal return line (tank line). Oil in the return line passes through
the return filter going to the hydraulic reservoir which creates
back pressure in the return line that is greater than the saw motor
seal can handle. The low pressure case drain line must connect
directly to the reservoir with no restrictions.
