INSTALLATION INSTRUCTIONS
WARNING !
To avoid serious injury or death, GUARDS, INTERLOCKS, SAFETY
DEVICES and ELECTRICAL CIRCUIT must be restored to correct operation
when installing parts or making adjustments or repairs.
PRESSURE SWITCH SETTING
Though set at the factory, it is recommended that the pressure switch setting be
checked prior to placing the unit in service to ensure that the power unit motor is
turning off when the carriage reaches the fully raised position.
8. Make sure top stop bolts and nuts are installed and tightened per instructions
above.
9. Raise the lift carriage to full travel against the top stops. Pressure gauge reading
should be 2800 psi (all air must have already been bled from the hydraulic circuit
before this is done).
10. If pressure does not read 2800 psi or the motor does not automatically shut off, cut
off electrical power to the motor at the main disconnect.
11. Adjust the pressure switch setting per the steps shown in Figure 23.
12. After adjustment, reconnect power to the motor and raise the lift to the top stops
again. If the pressure is at 2800 psi and the motor turns off, make sure pressure
switch adjusting nut is locked in place.
13. Run the lift carriage few travel a few more times to ensure that the setting is
correct.
