HYDRAULIC PRESSURE ADJUSTMENT PROCEDURES
♦
Before attempting to check and/or adjust pressure relief valves, operate the machine for
15 minutes or long enough to sufficiently warm the hydraulic fluid.
♦
Insert a 0-3500 psi gauge onto the pressure test port on the valve manifold using gauge
adapter fitting MEC part no. 8434

Pressure Adjustment Table
Check and Adjust Pressure (except counterbalance)
If adjustment is required, set pressure to the correct setting as follows:
♦
Connect pressure gauge (0-3500 psi) with a female quick disconnect to the main test port.
Main/System
♦
Disconnect forward or reverse coil of drive valve.
♦
Energize drive function by moving joystick (lever) in the direction of the already
disconnected coil.
♦
Hold the switch for 10 seconds to get an accurate reading on the pressure gauge.
Lift
♦
Energize the platform to full extension with
no load on platform
.
♦
Hold the switch for 10 seconds to get an accurate reading on the pressure gauge.
Steering
♦
Energize the steering to full left.
♦
Hold the switch for 10 seconds to get an accurate reading on the pressure gauge.
Early Models
Early models do not have a tamper proof cap.
♦
Turn adjustment screw “IN” to increase the pressure.
♦
Turn adjustment screw “OUT” to decrease the pressure.
Current Models
♦
Remove the tamper proof cap.
♦
Turn adjustment screw “IN” to increase the pressure.
♦
Turn adjustment screw “OUT” to decrease the pressure.
♦
When correct pressure is obtained replace tamper proof cap with a new one.
CAUTION: Do not operate pump with tamper proof cap removed as fluid will emit
under pressure.
