WALKING FLOOR
®
unloader with the doors of the truck/trailer closed. Catastrophic failure to the
truck/trailer, as well as serious injury or death may occur.
DANGER:
Use caution when opening doors. Material can become compacted against doors
and they can open violently causing serious injury or death.
DANGER:
NEVER allow anyone to stand or move through the area where the load is being
discharged or go under truck/trailer body or enter truck/trailer while the system is operating.
Burial, loss of limb or life may occur.
WARNING: While unloading, NEVER leave truck and trailer unattended.
1. Set parking brake on the truck/trailer and follow the Pre-Trip Check List.
2.
Inspect hydraulic hoses and quick connects for contamination or damage (if applicable), then
connect the floor to the truck wet kit.
3.
If the load is covered with a tarp, remove and secure the tarp prior to engaging the floor.
4.
Manually open truck/trailer rear door(s) fully and secure door(s) with provided chains or loop rings.

operate! Ball Valve handle is located between the pressure and return lines.
NOTE:
The ball valve
controls On/Off and is used as an emergency stop.

when the pile of material gets too high. Reduce engine RPM’s and move the truck/trailer forward
(load will begin to move again). Repeat until the material is completely unloaded.
12.
After loading/unloading is completed, reduce engine RPM’s to idle and stop the floor with all slats
in the forward position by pushing the ball valve handle in to the fully open position.
