In general, use any good-quality 30-weight hydraulic oil. More
specifically, you should use premium-quality hydraulic oil with
a viscosity range of 150-300 SUS at 100°F. Normal operating
viscosity range is between 80-1000 SUS. Maximum start
up viscosity should not exceed 4000 SUS. Oil should have
maximum anti-wear properties, rust and oxidation inhibitors.
Check the hydraulic fluid level before every use. The system
holds approximately 35-40 gallons of fluid. A sight gauge
located on the reservoir will indicate the fluid level. Fluid
should fill at least three-quarters of the way up the gauge.
Change the filter after the first 50 hours of initial use, and
then every 250 operating hours. The replacement filter
should be rated for 10 micron filtration.

DO NOT
check for leaks while system is operating, as high-pressure oil
leaks can be dangerous!
DO NOT
check for leaks adjacent to moving parts while system is
operating, as there may be danger of entanglement.
WARNING!

Hydraulic Maintenance
Under normal operating conditions, the temperature of the hydraulic oil should
be approximately 135-165°F.
For no reason should the oil temperature be above 185°F.
Overheated oil can cause damage to the hydraulic system, shortening the life
of pumps, motors, and other components.
High Duty cycle optioned units will have an oil cooler installed. Normal
operating temperatures will be in the 135

-145

range.
