THE BANDIT HYDRAULIC SYSTEM
After the initial start‑up of the machine and after any replacement of hydraulic components, fittings and
hoses must be re-checked for leaks and clearances.
CAUTION
!
The Bandit is equipped with a very efficient, simple
hydraulic system. Each component is capable of
withstanding a specified 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
specified 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 first.
•
Only use the optional adjustable flow 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 flow unless chipping large
diameter trees.
•
Do not close the optional hydraulic shut‑off valve
for more than 3 to 4 seconds. Hydraulic shut‑off
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 different
specific hydraulic lubrication, such as gear boxes,
undercarriage drives, etc. Refer to their manuals and
maintenance section of this manual.
• After you have operated a new machine for
approximately an hour shut down the machine and
recheck all hydraulic fittings 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 specified PSI (bar). This will cause
damage to hydraulic components. Do not set
any other hydraulic component past it’s specified
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 filter(s) after first 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 flush and
clean the tank. Replace hydraulic oil immediately if it is
contaminated or looks “milky”. See pages 79 - 80
for hydraulic oil requirements.
