Apparatus Pointed Down-Hill
Figure 4-3: Wheel Chock Placement - Pointed Down Hill
POM0850A
NOTE: If the set-up at the scene is more than a 5° down-hill slope or compound down-hill angle (with some
side-to-side slope), it is recommended to install the front stabilizer jack extensions (See
“Front
Stabilizer Jack Extensions (Optional)”
on
page 4-29
.) to achieve Apparatus Leveling Safe
Operating Limits. See
“Load Chart and Level Chart Information”
on
page 3-1
.
1. Prepare apparatus for stabilizer deployment. See
“Preparing Apparatus for Stabilizer Deployment”
on
page 4-5
.
NOTE: If Short-Jacking apparatus, both middle stabilizer beams may not be fully extended. See
“Short-
Jack Stabilizer Set-Up”
on
page 4-13
.
2. Extend the middle stabilizer beams, as conditions allow, until the middle stabilizer beam fully extended indicator
light is illuminated.
3. Lower the middle stabilizer jacks until the middle stabilizer jacks firm on ground indicator light is illuminated.
4. Push and hold the Level Assist Button until the front (bumper) and rear stabilizer jacks are down and the firm
on ground indicator is illuminated for all stabilizers. Level Assist sequence will be as follows:
a. Levels the side to side (slope).
b. Deploys the Front (Bumper) stabilizers before the Rear stabilizers.
c. Levels the Front to Rear (grade).
5. Lower each jack until the firm on ground indicator is illuminated for all stabilizers.
NOTE: The #2 axle tires can be on or off the ground as long as the on-ground indicators are illuminated
and the angle indicators show that the apparatus is within the safe level range in slope and grade.
6. Push and hold the Level Assist Button until the truck auto-levels and all the stabilizers stops moving.
7. If the apparatus will NOT level within the safe range of the angle indicators in slope and grade using the Level
Assist Button, proceed to step 8. If the apparatus WILL level within the safe range of the angle indicators in slope
and grade using the Level Assist Button, proceed to step 9.
