MODEL 20XP
The Bandit is equipped with a very e󰀩cient, simple
hydraulic system. Each component is capable of
withstanding a specied PSI (bar) and still operate
for a very long time.
If the simple rules mentioned below are followed, the
hydraulic components will last for years:
• If the Bandit’s hydraulic system is kept clean and
the hydraulic pressures are not increased beyond the
specied PSI (bar), the maximum use and life should
be received from the Bandit chipper hydraulic system.
• If a problem is encountered, it will more than likely
be located in the relief valve or something as simple
as belts or clutch slipping, check these rst.
• Only use the optional adjustable ow control when
chipping large diameter trees. Do not leave the speed
adjustment partially open for long periods of time. This
will cause excessive heat to the hydraulic system!
Excessive heat will cause low feedwheel power and
premature failure of all hydraulic components. Always
operate system at full oil ow unless chipping large
diameter trees.
• Do not close the optional hydraulic shut-o󰀨 valve
for more than 3 to 4 seconds. Hydraulic shut-o󰀨
valve handle must be completely turned on (in line
with hose) at all times unless checking hydraulic
pressure. Pressure gauge should be safely stored and
installed only when checking pressure. Follow above
instructions or this will cause unwarranted damage to
the hydraulic components.
• Never close the ball valves on the hydraulic
tank suction ports (if equipped) while the machine
is running, this will ruin the hydraulic pump and
components.
• Some component manufacturers require di󰀨erent
specic hydraulic lubrication, such as gear boxes,
undercarriage drives, etc. Refer to their manuals and
maintenance section of this manual.
HYDRAULICS
HYDRAULICS
After the initial start-up of the machine and after any replacement of hydraulic components, that ttings
and hoses should be re-checked for leaks and clearances.
CAUTION
!
THE BANDIT HYDRAULIC SYSTEM
• After you have operated a new machine for
approximately an hour shut down the machine and
recheck all hydraulic ttings for tightness and leaks.
• Avoid hydraulic pump cavitation. Low oil levels
or cold start-ups will cause the hydraulic pump to
cavitate. Cavitation will ruin the pump and possibly
the entire hydraulic system. Cavitation only has to
happen once. This will start the pump on its way to
ruin. Allow hydraulic system to turn slowly for several
minutes in cold weather in order for hydraulic system
to warm up. Cavitation is not covered under warranty.
• Do not increase the feedwheel relief valve
settings beyond specied PSI (bar). This will cause
damage to hydraulic components. Do not set
any other hydraulic component past it’s specied
pressure or this will cause damage to the hydraulic
components.
• Keep hydraulic oil clean. Dirty oil will cause
excessive wear and loss of hydraulic power.
• Replace the hydraulic oil lter(s) after rst 10
hours and with each 400 hours of operation or 3
months.
• Replace hydraulic oil & suction screen(s) at least
once yearly. This is also a very good time to ush and
clean the tank. Replace hydraulic oil immediately if it is
contaminated or looks “milky”. See pages 74 - 75
for hydraulic oil requirements.

WARNING
!
• Pressured oil easily punctures skin causing
injury, gangrene or death.
• Seek immediate medical care.
• Do not use  nger or skin to check for leaks.
• Remove hydraulic pressure or load before
loosening  ttings.
• Hydraulic components and oil may be hot.
Allow su󰀩 cient time to cool.
• Avoid burns from  uid. Hot  uid under
pressure can cause severe burns.
DO NOT GO NEAR LEAKS!
