2. Set the main electrical shutoff switch to the
OFF position.

3. Trip circuit breakers CB2 & CB6.

4. Disconnect the chassis ground cable “00”
(GND) from the appropriate battery post
(figure on your right).

CAUTION
Position welding machine ground clamp as close as possible to the work. Ensure that
the welding machine ground return clamp is well secured and makes a good electrical
contact with a large metallic area of the chassis located as close as possible to the
welding point.
5. Once the welding works completed, perform the previous steps in reverse order. Torque the ground
cable nut according to specifications found in Section 06 Electrical.

PROCEDURE

DANGER
Park vehicle safely, apply parking brake, stop the engine. Prior to working on the vehicle, set the
ignition switch to the OFF position and trip the main circuit breakers equipped with a trip button.

1. Park the vehicle with truck wheel blocks.

FIGURE 1

2. Apply the disconnection procedure shown at
the beginning of this instruction sheet prior
welding.
3. Extend the slide-out completely.
4. Gently remove the membrane covering the
lower side walls and the lower center wall and
avoid breaking the insolation panels behind.

IMPORTANT NOTE
There are isolation panels and aluminum
structure behind the membrane. The panels
are to be removed and preserved for
reinstallation. The membrane as a sticky side
in contact with the isolation panels and glue
was applied for the contact with the aluminum
structure. Remove the membrane gently to
avoid breaking the panels.

6. Remove gently both isolation panels on the
right lower wall of the slide-out
7. Keep the panels in a safe place.

10. On the left side of the lower center wall, mark a
horizontal line on the insulation panel of 310
mm high from the slide-out floor.
11. Extend this cutting line up to the last insulation
panel on the right side of the lower center wall.

12. Make two spacer blocks at 135 mm high.

FIGURE 6

13. Make one spacer block at 163.4 mm high.

14. Install reinforcement tubing on the center wall
structure. Adjust the vertical position of the
tubing with a 135 mm high spacer block at both
ends and a 163.4 mm high spacer block in the
middle.
15. Make sure the 135 mm high spacer blocks
stand on the aluminum slide-out structure and
not on the wooden floor.

16. Mark a line on all insulation panels using the
top of the reinforcement tubing as reference.
17. Mark a line on all insulation panels using the
bottom of the reinforcement tubing as
reference.

18. On each insulation panel, write down marks to
each section (A to E) as shown in Figure 10.

FIGURE 10

19. Use a professional cutter and cut all sections of
the insulation panels following the cutting lines.
Set the blade to 25 mm out of the blade holder.

20. Remove all insulation panel sections and keep
in a safe place.

21. With the professional cutter, remove all the old
membrane bottom sealant on the slide-out
floor.

22. Prepare a mini air polisher with a new sand
paper.

IMPORTANT NOTE
The polisher is to be used to clean the glue on
the existing aluminum structure to prepare the
welding areas. It is important to use a new
sand paper to avoid contamination of the
aluminum.

23. Install the reinforcement tubing with the spacer
blocks. Make sure the 135 mm high spacer
blocks stand on the aluminum slide-out
structure and not on the wooden floor.
24. On the left-hand side of the lower center wall,
use air polisher to clean old glue on the
existing aluminum structure (pole). Clear a
minimum of 50 mm all around the
reinforcement tubing future welding area.

FIGURE 14

25. Repeat previous steps for all the diagonal
square existing tubing and the existing pole on
the right hand.

FIGURE 15

26. With a new sand paper grind the reinforcement
tubing at each weld location over and under to
remove the natural aluminum oxide layer
protector.
