Hydraulic System - Grizzly G0812 Owner's Manual

Hydraulic System

The hydraulic system must be maintained on a
regular basis and kept in good operating condition
to avoid premature wear of moving parts, hoses,
and valves.
If you have never maintained a hydraulic system
before, WE STRONGLY RECOMMEND that you
read books, get formal training, or seek the help
of a qualified hydraulic service technician.
Checking Hydraulic Fluid
1. DISCONNECT MACHINE FROM POWER!
2. Remove front access panel (see Figure 70).

3.
Check fluid level and temperature on fluid
gauge mounted on front of hydraulic tank
(see Figure 71). Fluid level indicator should
be halfway between "L" (low) and "H" (high).
— If fluid level is low, proceed to Changing
Hydraulic Fluid.

IMPORTANT: The operating temperature of the
hydraulic fluid should not exceed 140°F (60°C)
with an optimum operating temperature window of
50–95°F (10–35°C). If the fluid temperature rises
above 140°F, stop the machine immediately and
allow the fluid to cool down.
If this condition continues during operation, stop
using the machine immediately, then review
Troubleshooting on Page 51. If you still cannot
remedy the problem, contact a qualified hydraulic
service technician or our Tech Support.
4. Remove tank fill cap and inspect for burnt-
smelling or tan-colored, water-contaminated
hydraulic fluid.
— If fluid is contaminated, proceed to
5.
Re-install tank cap and front access panel.
Changing Hydraulic Fluid
The hydraulic fluid should be changed after the
first 50 hours of use, then every 5,000 hours of
use after the initial changing.
