10. Retract the jack fully. Remove and store the caster, if
applicable.
11. Check for proper truck-trailer hook-up; the tow vehicle and
trailer should be level with a positive tongue load. For further
information, consult a dealer or Atwood Service Center.
12. The direction lever must be positioned in the “Towing
Position” (Figure 41).
BACKING UP
1. Refer to the previous steps 1 through 14 for Towing.
2. Before backing up a slope or through soft ground, pull the
trailer forward slightly to assure that the actuator socket is in
the fully forward position.
3. Move the directional lever on the side of the actuator
downward from the “TOWING” position along the curved slot
in the actuator frame to the “BACK-UP” position (Figure 41).
The slot has a notch at the bottom of its travel. Push the
directional lever down to engage the locking notch.
4. Back the trailer up.
ST-45 — TOWING INFORMATION
Before towing the pump, always ensure that
the directional lever (Figure 41) has been
disengaged and is in the “Towing Position.”
5. If the pump is to be uncoupled from the tow vehicle after
backing with the lever knob engaged, block all pump wheels
and pull forward slightly to take strain off of the actuator.
Uncouple the actuator by lifting the release handle and raising
the trailer tongue. Make sure the lever knob is in the “Towing
Position” when uncoupling from the trailer.
Avoid sharp turns. This could bend, create
extreme stress or fracture either the actuator
or trailer tongue.
