INSTALLATION INSTRUCTIONS
7. Run the FREIGHTLIFT to the top floor and check the alignment of the platform
carriage. Re-adjust the stops as necessary to achieve alignment with the upper
floor. Be sure that at least 1” clearance is present between the carriage and all
building structures, and other site constraints.
8. Adjust the top level limit switch to make contact with the carriage limit switch cam.
9. Lower the FREIGHTLIFT a few feet and raise it back to its full travel. Run it hard
against the mechanical stops and check carriage alignment once more.
H. FINAL ADJUSTMENTS
1. Run the system through is paces if you have a complete electrical system.
2. To change the actuation direction of the limit switch, remove the switch head.
Change the actuating control knob/mechanism to the desired actuation direction.
RELIEF VALVE SETTING
Though set at the factory, it is recommended that the pressure relief setting be
checked prior to placing the unit in service.
3. Make sure top stop bolts and nuts are installed and tightened per instructions
above.
4. Qualified electrician can temporarily place a jumper wire between terminal blocks 9
and 10 for testing the relief circuit.
5. Once placed, raise the lift carriage to full travel against the top stops. Pressure
gauge reading should be 3200 psi (all air must have already been bled from the
hydraulic circuit before this is done).
CAUTION!
Do not operate motor at relief pressure! The motor should not be
operated for more than a few seconds when the unit is operating at relief
pressure. Longer running times could result in damage to the pump.
6. If pressure does not read 3200 psi, adjust the relief valve setting per the steps
shown in Figure 22.
7. After adjustment, check the setting one more time before removing the jumper
from the motor control panel.
NOTE: This jumper MUST be removed from the circuit.
