Maintenance
Hydraulic System
Checking Hydraulic Fluid

To check hydraulic fluid level, first ensure that
all cylinders: (
levelwind and jacks) are
retracted, and that the pump is off.

View the hydraulic fluid level in reservoir
through the sight gauge.

Fluid should show within (High/Low) limits of
the sight gauge.
Adding Hydraulic Fluid

Clean around hydraulic fluid reservoir, and
then remove reservoir cap or panel.

Carefully pour fluid into tank so that it reaches
within the (HIGH/LOW) limits of the sight
gauge- about ¾ of the way full just below the
HIGH mark is recommended.

Replace and tighten the fluid reservoir access
(cap/panel).
NOTE: If adding a small amount of fluid to the
system, use the small oil fill cap for access. Cap
must be reinstalled and hydraulic system cycled
(use jacks) before sight gauge will read added fluid.
If adding a large amount of fluid, remove the center
panel, gasket, and filter, then pour fluid into center
hole. Reinstall filter, gasket, and panel once
complete.
NOTE: If the tank is overfilled, or there is air in the
system, hydraulic oil may pour out of the bottom of
the breather cap when the hydraulic system is
charged. Use a drip pan where appropriate.
