To check hydraulic pressure on C7 - E6 revision LT30HD/LT40HD mills:
1. Disconnect power from the pump by moving the saw head forward until it no longer con-
tacts the power strip.
2. Locate the fitting on the front toe board cylinder. Disconnect the hydraulic hose from the
fitting and install a gauge to the fitting. NOTE: Installing the gauge at the front toe board
fitting port will insure the pressure reading is not affected by a relief valve.
3. Restore power to the pump by moving the saw head back until it contacts the power strip.
4. Operate the toe board hydraulic lever and read the pressure on the gauge. Hydraulic
pressure is factory-set at 2000 ±100 psi and should not need to be readjusted. Contact
the factory for service.
CAUTION!
Pressure should not exceed 2100 psi. If it does,
the amp draw will rise above the maximum of 200 amps,
and could cause battery and system problems.
