Raising Cab

1. Park the machine on level ground with dump body lowered. Engage park brake. Turn ignition switch OFF. Turn battery disconnect switch OFF.

2. Move mirrors to normal operating position. Ensure that no people or loose objects are inside cab or on right-side platform. Close cab door and right-side compartment access door securely.

3. Open hood.

4. Remove cab mounting cap screws, washers, and nuts (1) from left-front and left-rear cab mounts.

5. Rotate pump valve lever (8) counterclockwise to raise position.

6. NOTE: Pump handle is stored on floor of cab, to left of operator's seat.

   Remove pump handle (6) from storage position. Insert pump handle into pump socket (5).

7. Operate pump using long, firm strokes to raise the cab. When cab is fully raised, support pin (3) must line up with detent slot (2) at top of support strut (4).

8. CAUTION: DO NOT work under the raised cab unless the support strut is properly engaged.

   While pushing support strut handle (7) toward machine, slowly rotate pump valve lever clockwise to lower position. Cab will begin to “float” down. Support pin MUST be seated securely in detent slot at top of support strut.

9. Rotate pump valve lever counterclockwise to raise position.

Lowering Cab

1. Ensure that no people or foreign objects are present under the cab, and that the cab's movement is not obstructed.

2. Operate pump to raise cab fully. Support pin must slide free of detent slot at top of support strut.

3. CAUTION: Cab will “float” down when pump valve lever is rotated clockwise. Stay clear of cab while lowering.

   NOTE: Support strut handle must be pulled away from machine while cab is lowered, or support pin will engage secondary detent position on support strut.

   While pulling support strut handle away from machine, slowly rotate pump valve lever clockwise to lower position. Allow cab to lower until cab mounts are at rest.

4. CAUTION: Avoid possible injury from crushing and pinching. Use proper tools when installing cab mounting hardware. DO NOT grasp cab mounts with bare hands when support strut is not securely engaged.

   NOTE: Install new mounting hardware when cab is lowered.

   Install new cab mounting cap screws, washers, and nuts on left-side cab mounts. Tighten to specification.
