HYDRAULICS
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 machine’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 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.
• 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.
THE BANDIT HYDRAULIC SYSTEM
• 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.
• 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”. Refer to “Hydraulic
Fluid Requirements” for more information.
If the simple rules mentioned below are followed, the hydraulic components will last for years:
Some equipment and components such as
uid engagement clutches (PTOs) have their own
lubrication requirements. Consult the manufacturer’s
manual for that information.
When returning hydraulic components for
warranty make sure to box up all warranted parts
to avoid additional damage while shipping. Do
not disassemble any hydraulic components
which are to be warranted. Anything which has
been disassembled or tampered with will not be
warranted. Items being returned must be clean. All
hydraulic components must have all hosing ports
plugged. Failure to plug ports will allow debris to
enter components which will void warranty.
DO NOT operate this machine unless all hydraulic
control devices operate properly. They must function,
shift and position smoothly and accurately at all
times. Faulty controls can cause personal injury!
It is very important after you have operated a new
machine for approximately an hour to shut down the
machine and recheck all hydraulic ttings. Relieve all
pressure and retighten as needed.
DO NOT GO NEAR HYDRAULIC LEAKS! High
pressure oil easily punctures skin causing serious injury,
gangrene, or death. Avoid burns from uid. Hot uid
under pressure can cause severe burns. DO NOT use
ngers or skin to check for leaks. Lower load or relieve
hydraulic pressure before loosening ttings. Relieve
all pressure in the system before disconnecting the
lines, hoses, or performing other work. Use a piece of
cardboard to nd leaks. Never use your bare hands.
Allow system to cool down to ambient temperature
before opening any coolant or hydraulic oil system.
In cold weather situations let your hydraulic system
idle for approximately 15 minutes to allow the system
to warm up to operating temperature.

NOTICE
Before attempting any type of maintenance,
disengage clutch, wait for the cutterhead to come to
a complete stop, turn o󰀨 engine, remove the ignition
key, make sure the ignition key is in your possession,
wait 2 minutes and then disconnect the battery.
After the initial start-up of the machine and after
any replacement of hydraulic components, ttings
and hoses must be re-checked for leaks and
clearances.
