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 power unit access panel
(see
Figure 82).
4. Check fluid temperature on thermome-
ter mounted to hydraulic fluid tank (see
Figure 84). The temperature should read
between 50–95°F (10–35°C).
— If fluid temperature exceeds 140°F (60°C),
stop machine immediately and allow fluid
to cool down. Review
Troubleshooting
on
Page 60 for solutions. If you still cannot
fix the problem, contact a qualified hydrau-
lic service technician or Tech Support.
5. Remove tank cap (see Figure 84) and inspect
for burnt-smelling or tan-colored, water-con-
taminated hydraulic fluid.
— If fluid is contaminated,
proceed to
Changing Hydraulic Fluid.

3. Remove hydraulic power unit access panel
(see Figure 82).

4. Check pressure gauges shown in Figure 83.
Gauges should read less than 498 PSI.
— If vise pressure gauge reads more than 498
PSI, refer to Adjusting Vise Clamping
Pressure on Page 42 to adjust pressure.
— If manifold pressure gauge reads more
than 498 PSI, proceed to Step 5.
— If both gauges reads 498 PSI or less, no
adjustment is necessary. Install hydraulic
power unit access panel.

5. Adjust pressure relief valve until mani-
fold gauge displays 498 PSI or less (see
Hydraulic System Diagram on Page 77).
Note: Connect machine to power and
run hydraulic system to check pressure
adjustment.
