Check Daily or Before Use
• Check hydraulic oil level. Keep level
between “add” and “full” on dipstick.
• Check belt tension and idler pulleys on
engine clutch pump system.
• Examine hydraulic hoses for cracks or
leaks.
SAFETY WARNING!
Do not check for hydraulic leaks with
your hands while the system is
operating. Use a piece of wood or
cardboard. Hydraulic fluid escaping
under pressure can penetrate the skin
and may cause death if not treated
immediately.
Grease
• Grease the locations indicated in the
illustration below once per week.
Hydraulic Pressure
• Hydraulic system pressure should be
2450 psi.
• To check pressure, hook a test gauge
to the quick-couplers.
Hydraulic Oil
• Change hydraulic oil when it is milky in
appearance, or annually.
• Change hydraulic oil filter after the first
40 hours of use and then every 250
hours, or annually thereafter.
In Cold Weather (below 10° F)
• Fill with hydraulic oil specifically rated
for cold weather.
• Do not attach other hydraulic
equipment to the bed. The oil will
intermix and the cold weather viscosity
will be lost.
Other Maintenance Notes
• If the quick-couplers leak, the o-rings
inside may need to be replaced.
• High heat, 190° or greater, can be
damaging to the hydraulic system.
Feel various parts of the system to
make sure there are no “hot spots”
which may indicate a problem.
• For easy hookup of the couplers, shut
switch “off” and activate control valve
switches with the ignition “on”. This
will release the pressure in the lines.
• In the off season, run the bed at least
twice a month to prevent valve
condensation.
