Lifting Arm
163
To adjust the end cushioning of the In/Out cylinder:
1.
Secure the arm working area using barrier tape or barricades.
2.
Put the transmission in neutral.
3.
Start the engine and engage the hydraulic pump.
4.
Fully extend and retract the Helping Hand
TM
to check if more cushioning is needed.
The arm should not hit hard at the end of its strokes. End of stroke cushioning should provide
smooth operation of the arm.
5.
If cushion adjustment is necessary, stop the hydraulic pump and turn off the engine.
6.
Tighten the corresponding adjustment screw to achieve a smoother movement at the end of the
stroke or loosen the screw if the movement is too slow (no shock should occur).
Use the adjustment screw on the curb side for the end-of-stroke extension motion (See A in
Figure 10-11); use the adjustment screw on the street side for the end-of-stroke retraction
motion (See B in Figure 10-11).

6.
Tighten the corresponding adjustment screw to achieve a smoother movement at the end of the
stroke or loosen the screw if the movement is too slow (no shock should occur).
Use the adjustment screw on the curb side for the end-of-stroke lowering motion (See A in
Figure 10-12); use the adjustment screw on the street side for the end-of-stroke raising motion
(See B in Figure 10-12).
