The amount of pressure the GRL arms use to clamp the container is controlled with a pressure relief valve in the GRL
control valve. This valve is preset at the factory to operate with most containers. However, if the lifter seems to be
crushing or loosing grip on your specific containers, refer to Figure A-3 while performing the following steps to properly
adjust the clamping pressure.
1. Loosen the lock nut on the pressure relief valve in the GRL control valve.
2. If the lifter is crushing the waste container, turn the adjustment screw counterclockwise 1/4 turn. If the lifter is loosing
grip on the waste container, turn the adjustment screw clockwise 1/4 turn.
3. Repeat clamping and dumping the container, making necessary adjustments to the pressure relief valve in 1/4 turn
increments until the lifter securely holds the container without crushing it.
4. Tighten the lock nut on the pressure relief valve to secure the correct pressure setting.

D.Final operation and mounting:
1. Start the truck’s engine and engage the hydraulic system.
2. Operate the lifter and bleed all air from the hydraulic system.
3. Place a cart on the lifter and operate to make sure there are no clearance problems and that the lifter engages the
cart properly. Make any adjustments to the mounting position of the lifter to ensure correct operation.
4. After locating an acceptable mounting position, complete the welding of the lifter to the truck.
