DOCK LIFT EXTERNAL POWER PACK INFORMATION
NOTE: All lift times are calculated for a dock lift that requires (2) total cylinders. Lifting and lowering times will increase with the number
of cylinders required. Please consult factory for actual lift times for specific applications.
FIGURE #5
solve the issue see the trouble shooting section or
contact the factory.
If the motor is rotating in the incorrect directions this
could cause damage to the pump. Never let the
motor run longer than 3 seconds in the incorrect
direction. Always verify that the motor is turning in
the correct direction after installation.
14. Raise the dock lift to it’s full raised height.
15. Insert both maintenance bars as directed in the
maintenance section of this manual.
16. Lower the dock lift onto the maintenance bars.
(For single-acting cylinders only) continue to
depress the down button for 10 seconds to
relieve all pressure in the hydraulic system.
17. Clean up and clear the entire area around the
dock lift. Remove any material that is not
necessary for the use or function of the dock lift.
Make sure to remove all hydraulic oil from the
area. Hydraulic oil can cause unsafe work areas
and can be a fire hazard.
Any material or foreign objects in the area of the
dock lift could interfere with the movement of
the lift and cause damage. Because of pinch
points and geometry foreign objects that get
caught in the table could become projectiles and
cause personal injury or death.
Clean all hydraulic oil that is not contained in
the system. Failure to do so could result in fire
or unsafe working conditions which could cause
personal injury or death.
18. Raise the lift table to it’s full raised position.
19. Warn all personnel the lift table will be in use.
Raise the dock lift to it’s full raised height.
20. Remove both maintenance bars and place in a
safe place where it will not interfere with the use
of the dock lift.
21. Lower the dock lift to the fully lowered height.
Check the hydraulic oil level on the sight on the
side of the power unit. Fill as needed see the
maintenance section of this manual for
instructions.
22. Raise and lower the lift a few times making sure
to go from the fully raised height to the fully
lowered height. At the lowered height depress
the down button for 5-10 extra seconds to
relieve the system of it’s pressure. Verify that all
air is purged from the system. Make sure the
motor is running smoothly and quietly. The lift
should raise and lower smoothly.
23. Once the lift table has been tested fill in the se-
rial number, model number and date on the front
cover of this manual. On the back cover fill in
your company information, date installed and
contact number. By doing this you are agreeing
that the lift was installed as per the instructions
manual’s directions and per local codes and
regulations.
