Lifting Arm
165
To adjust arm speed:
1.
Lock out and tag out the vehicle (see
Locking Out and Tagging Out the Vehicle
2.
Secure the area around the path of the arm with barrier tape or barricades.
3.
Put the transmission in Neutral.
4.
Start the engine and engage the hydraulic system.
5.
Clearly identify the stopper screw on the valve that corresponds to the proper function (arm
extension/retraction, gripper open/close).
6.
Move the lever to evaluate arm speed, then release the lever.
Make sure the Speed-Up feature is activated. Engine speed should be at 1200
rpm.
7.
Loosen the locknut.
8.
Turn the restrictor adjustment screw only one eighth (1/8th) of a turn at a time to see a
significant change in the arm speed.
9.
Move the lever again to evaluate arm speed. Repeat until cycle times are properly set (see table
below).
10.
Tighten back the locknut.
Danger!
Do not stand in the path of the arm while carrying out these adjustments.
Caution!
When adjusting tilt movement speed, make sure the auto-closing feature allows the gripper
to close sufficiently to avoid gripper fingers hitting the hopper walls.
