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
To check hydraulic fluid:
1. Raise/lower headstock repeatedly for approx-
imately 10 minutes to warm up hydraulic fluid.
2. DISCONNECT MACHINE FROM POWER!
3. Remove hydraulic unit access panel on rear
of machine
.
4. Check fluid temperature on thermome-
ter mounted to hydraulic fluid tank (see
Figure 68). The temperature should read
between 50–95°F (10–35°C).
— If fluid temperature exceeds 140°F (60°C),
then review
Troubleshooting on Page 51
for solutions. If you still cannot fix the prob-
lem, contact a qualified hydraulic service
technician or Tech Support.
8. Re-install tank cap, slide hydraulic unit back
into base, and re-install front access panel.
Always wear safety gog-
gles when servicing the
hydraulic system.
5. Slide hydraulic unit out of machine base and
support weight of hydraulic unit with wood
blocks (see
Figure 68).
6. Remove tank cap (see Figure 68) and inspect
for burnt-smelling or tan-colored, water-con-
taminated hydraulic fluid.
— If fluid is contaminated,
proceed to
Changing Hydraulic Fluid on Page 47.

The hydraulic fluid level and temperature should

screen.
