CHECK ROOF HEIGHT AND ADJUST IF NECESSARY. SET THE DOOR TO MAKE SURE
IT IS STILL FITTING CORRECTLY. ADJUSTING THE ROOF HEIGHT
1. Raise the roof. NOTE: USE ROOF SUPPORT ON CORNER BEING ADJUSTED
‘G’. Measure from the bottom of the ‘H’ on the ‘H’–rail to the
edge of the sidewall cap. The measurement should be 47 ¼”, no
more than 47 ¾” for earlier 4 stage units. If you don’t have
enough room for the upper door to fit properly, raise the rear
arms to 47 ¾”. NOTE: For later 4 stage units the measurement is 46
¼” with a maximum of 46 ¾”. Also, the 3 stage units with the
higher side wall measurement was 42 ¼” to 42 ¾”.
2. If the measurements are not right, adjust the length of the bolts
by moving the nuts one way or the other. Lengthen they eye bolt
to lower, shorten eye bolts to raise.
3. To find out which eye bolt goes to which arm, pull an individual
3/32 cable and watch which corner of the roof goes up.
4. After the roof height is adjusted properly, set the red vinyl
cable so it is tight. Adjust the cable at the roof sideboard and
move up. This cable will tell you when the roof is up to the
correct height.
5. MAKE SURE THE NUTS ON THE EYE BOLTS ARE TIGHT. L&W CRANK UP LIFT SYSTEM – PART NUMBER INDEX

Tent Camper Cable Drive Lifter Repair Procedure:---
SPRING CHANGE PROCEDURE
It is important when changing springs to do only one end of the camper at a time. The roof should be down before repairing to take pressure off of the system. Refer to attached drawing for parts (A through Q) locations.
- Remove the tie bar plates (K) by removing two (2) self-tapping screws.
- Remove the two (2) screws that attach the spring tubes (N for rear, S for front) to the master tube (L).
- Remove two (2) screws each from floor plates that attach the spring tubes to the frame of the camper.
- Pull the spring (P) out from the bottom of the telescoping posts (A, B, & C).
- Pull the spring tube off of the spring.
- Pull the spring assembly (2 springs attached) out of the master tube (L).
- Put the new spring assembly in the master tube and push all the way to the stop. Note: The cable (J) lays between the springs and must s
lide freely. - Put the spring tubes on the springs. (You may put some oil in tube to ease pushing spring through).
- Attach the spring tubes to the corner of the frame of the camper.
- Attach the spring tubes to the master tube.
- Attach the tie bar.
- Repeat the above procedure on the opposite end of the camper if necessary.
CABLE REPLACEMENT PROCEDURE
System should be ready to use. You may put more grease in the master tube. If front and back of the roof do not start up at the same time you need to adjust the pulley (M). To Raise front of roof earlier adjust pulley forward to raise rear move pulley toward back of unit. | ||||||
