Jacking Procedures

7. When the wheel and tire assembly is on the ground, detach the cable and leave it

payed out in readiness for lifting the flat.

b. Secure the flat tire and wheel in the stowed position.

Secure the hoist cable to the wheel and tire assembly by inserting the hook

through an opening in the wheel, wrapping the cable around the tire, and attach-

ing the hook to the cable (see step a. 1.).

2. To raise the wheel and tire assembly, turn the hoist crank clockwise (raise). You

will hear a clicking sound made by the internal ratchet. If you stop turning the

handle or if your hand should slip off the handle, the brake will apply auto-

matically and hold the load.

3. On the M915, raise the tire and wheel assembly high enough to clear the lowered

carrier side panel. Push it toward the center of the carrier, raise the side panel

and secure with the wing nut. Connect electrical cable at tractor.

4. On the M916, turn the wheel so the back side is facing outward and raise the

tire and wheel assembly. When the wheel and tire assembly is aligned with the

tire rack, press the wheel against the rack so that the round plate on the rack fits

inside the wheel hub opening. While maintaining pressure against the tire, install

retaining strap and nut. Tighten the nut with the lug wrench.

5. After the tire and wheel has been secured, the cable may be slightly loose but

should remain attached to the wheel.

6. Crank handle must be in the 6 o'clock position when not in use to avoid inter-

ference with trailer.

WARNING

The hydraulic jack is intended only for lifting the truck,
