LDL Dock Lift Owners Manual
BREAK-IN AND PERFORMANCE CHECK
NOTE: IN SOME CASES THERE IS A CONSIDERABLE AMOUNT OF TIME BETWEEN THE SHIPMENT DATE AND
USE OF YOUR DOCK LIFT. THIS INITIAL BREAK-IN AND PERFORMANCE CHECK SHOULD BE PERFORMED
BEFORE YOU BEGIN REGULAR USE OF YOUR DOCK LIFT TO ENSURE THAT IT IS OPERATING PROPERLY.
BEFORE DOING ANY ELECTRICAL WORK, BE CERTAIN THAT THE POWER IS
DISCONNECTED WITH A FUSED DISCONNECT, PROPERLY TAGGED AND LOCKED
OUT. FUSED DISCONNECT AND LOCKOUT DEVICE (SUPPLIED AND INSTALLED
BY OTHERS) MUST MEET WITH ALL APPLICABLE CODES AND REGULATIONS.
ALL ELECTRICAL WORK MUST BE PERFORMED BY A QUALIFIED ELECTRICIAN IN
ACCORDANCE WITH ALL APPLICABLE CODES AND REGULATIONS.
ARC FLASH AND SHOCK HAZARD PPE (PERSONAL PROTECTION EQUIPMENT)
REQUIRED. DE-ENERGIZE EQUIPMENT BEFORE WORKING ON OR INSIDE. DO
NOT OPEN COVER WITHOUT APPROPRIATE PPE. REFER TO NFPA 70E FOR PPE
REQUIREMENTS. THIS PANEL MAY CONTAIN MORE THAN ONE POWER SOURCE.
HAZARDOUS VOLTAGE WILL CAUSE SEVERE INJURY OR DEATH.
NEVER GO BENEATH THE DOCK LIFT FOR ANY REASON UNLESS THE PLATFORM
AND HINGED BRIDGE(S) ARE PROPERLY SUPPORTED (See “Figure 10: How to Support
the Dock Lift for Maintenance” on page 15) AND THE POWER IS DISCONNECTED,
PROPERLY TAGGED AND LOCKED OUT. IT IS THE RESPONSIBILITY OF THE OWNER
TO ENSURE THAT NO LOAD OR TRAFFIC IS PLACED ON THE PLATFORM WHILE THE
MAINTENANCE STAND IS ENGAGED. THE CONSTRUCTION OF THE MAINTENANCE
STAND IS INTENDED TO SUPPORT THE WEIGHT OF THE UNLOADED DOCK LIFT ONLY.
BEFORE DOING ANY INSTALLATION, MAINTENANCE, INSPECTION OR TROUBLE
SHOOTING, BARRICADE ALL AREAS FROM TRAFFIC AROUND THE WORK AREA
INSIDE (& OUTSIDE IF APPLICABLE) FOR SAFETY, POST APPROPRIATE WARNING
SIGNS AND BE CERTAIN THAT THE POWER IS DISCONNECTED, PROPERLY TAGGED
AND LOCKED OUT. ALL ELECTRICAL WORK MUST BE PERFORMED BY A QUALIFIED
ELECTRICIAN IN ACCORDANCE WITH ALL APPLICABLE CODES.
1.
Ensure that any specified interlocks (e.g. overhead doors, restraints) are fully functional.
2.
It is important to purge air from the hydraulic system. To do this, raise the unit to its maximum raised height and allow
the power unit to run for a minimum of 30 seconds additional time. Fully lower the unit. Discontinue use of the unit for 20
minutes to allow air to dissipate from the oil in the reservoir.
NOTE:
Units equipped with an up travel limit switch will not
reach their “maximum raised height” unless the limit switch is
removed. The up travel limit switch must be removed to purge the air.
DO NOT remove the up travel limit switch
until first ensuring there are no obstructions in the operating path of the equipment.
After the air has been
purged, lower the dock lift to its desired raised height and reinstall the limit switch.
3. Raise the dock lift and install the maintenance stand as outlined on page 15.
4.
Inspect hydraulic system for leaks, especially at fittings and hose connections.
5. Dock Lifts do not require lubrication of the pivot points. For ease of maintenance, lifetime lubricated bushings have been
used on all rollers, leg pivot points as well as the upper cylinder pivot. However, units installed outdoors or in wet and dirty
environments should be lubricated. See the Maintenance and Lubrication Section, page 16.
6.
Ensure the toe sensor (if equipped) is functional.
NOTE:
The toe sensor option is an electrical safety device with an actuator suspended beneath the platform which halts
downward travel of the dock lift if it contacts with an obstruction.
NOTE:
This feature is not functional in the event of hydraulic failure.
7. Completely raise and lower the dock lift three times.
As the performance test is being conducted, watch closely for any signs that the dock lift
might not be operating properly. If you are in doubt, refer to Operating Instructions on page
13 and Troubleshooting Guide on page 19 or contact your Pentalift representative.
NOTE:
Read the SAFETY INFORMATION AND WARNINGS before operating the dock leveler. (See page iii)
