4.0 Operation
4.1 System Check - Initial Start-Up
9
Read through this manual. If there is any confusion, contact a KEITH representative and resolve
any concerns before operation of this system
9
Inspect all fasteners and fittings for proper torque.
9
Ensure there are no leaks and that all lines are secure before putting the trailer in service.
4.2 Normal Operation
1.
Verify that the tarp is fully retracted and that there is 12”-14” [305-356 mm] of tarp covering the floor
slats prior to loading the trailer. It is recommended that a viewing window/port be installed in the
top of the front trailer wall so the operator can verify that the tarp is fully retracted from the winch
operating position prior to loading.
2.
DO NOT let material build up on tarp.
It is recommended that the trailer be moved forward
periodically during unloading and especially near the end of the unloading cycle, move it 6’-10’ [1830-
3050 mm] to reduce the amount of material unloaded on top of the tarp.
3.
After unloading the trailer make sure to stop the floor with all of the slats to the front of the trailer.
Dislodge the tarp by hand from underneath any material that may have been unloaded on top of
the tarp.
DO NOT attempt to pull the tarp from under a load by using the winch or moving the
trailer
– this may damage the winch, tarp, strap or trailer. Installing catch hooks (optional) on the
end of the trailer will catch and hold the tarp and make sure that it doesn’t get buried in the load.
4. Ensure hydraulic power is supplied to the trailer and engage the winch by activating the power switch
(electric systems) or pulling out the manual valve knob (manual systems).
5.
The tarp takes 10-20 seconds to retract and when fully retracted hydraulic fluid delivered to the
winch is redirected through the relief valve in the manifold. Full retraction can be verified through
the viewing window/port (if installed), otherwise it is signified by an audible bang as the tarp top pipe
impacts the strap roller, as well as an audible change in the hydraulic system sound as the fluid is
directed through the relief valve. At this point disengage the winch and verify that the tarp is fully
retracted.
