Adjust Stored Limit Switch & Down Speed Flow Control
Stored Limit Switch Adjustment
Note: The dock leveler should lean towards the door
by the following amount when in the stored position:
• 5’ and 6’ levelers: 5 degrees from vertical
• 8’ levelers: 10 degrees from vertical
To change the angle, adjust the Stored Limit Switch:
1. Put the dock leveler in the stored position with the
lip folded.
2. Turn OFF all electrical power to the leveler.
3. Lock out and tag out the dock leveler, then ensure
the storage prop is locked with the prop pin and clip.
4. Loosen set screw ( A ) on switch arm.
5. With roller arm ( C ) contacting storage prop, rotate
adjustment screw ( B ) counter clockwise until a “click”
noise is heard.
6. Tighten set screw ( A ) on switch arm.
7. Remove prop pin and clip.
8. Remove lock out/tag out devices and turn ON
electrical power to the leveler.
9. Test leveler and repeat steps 1– 8 as necessary.
10. Once correct angle has been set, check storage
prop for play and adjust if needed (see page 31).
Down Speed Flow Control Adjustment
Note: The down speed flow control is factory set. If
original setting is lost, or if the dock leveler lowers
too rapidly or too slowly, the flow control valve ( D )
requires adjustment.
When properly adjusted, the dock leveler will take
15-20 seconds to descend from stored to full below
dock position. To adjust the flow control:
1. Put the dock leveler in the stored position with the
lip folded.
2. Turn OFF all electrical power to the leveler.
3. Lock out and tag out the dock leveler, then ensure
the storage prop is locked with the prop pin and clip.
4. Loosen the allen head set screw ( F ).
5. Set adjusting knob ( E ) as follows:
• To decrease the lowering speed, adjust knob ( E )
clockwise.
• To increase the lowering speed, adjust knob ( E )
counterclockwise.
6. Once ideal down speed flow control setting is
achieved, lock the adjustment in place by tightening
the hex screw ( F ) on the adjustment knob.
Note: Do not overtighten the set screw.
7. Remove prop pin and clip.
8. Remove lock out/tag out devices and turn ON
electrical power to the leveler.
9. Test leveler and repeat steps 1– 8 as necessary.
