WARNING
LIFT WEIGHT IS APPROXIMATELY 350-375 LBS. TAKE EXTREME CARE WHEN POSITIONING BECAUSE
STEPWELL BRACKETS MAY TIP. THIS PROCEDURE SHOULD NOT BE ATTEMPTED BY ONE PERSON.
a. With doors fully open, position lift in vehicle doorway as close as possible to inside surface of door. Lift
baseplate must be parallel to side of vehicle.
b. Refer to
Figure 2-8
. Mark and drill ten 25/64" baseplate mounting holes (1 thru 10) through vehicle floor.
CAUTION
Before drilling holes, verify that underlying wires and tubing will not be damaged.
c. Fasten Lift:
1) Insert ten 4" x 3/8" carriage bolts through baseplate and vehicle floor.
2) Refer to
Figure 2-7
. Install four clamping bars to bolts underneath vehicle floor across baseplate, i.e.,
from 1 to 6, 2 to 7, etc, and secure lift to vehicle floor with 3/8" washers, lock washers and hex-nuts.
3) Tightening carriage bolts requires special care to keep baseplate assembly from warping when secured
to vehicle floor. If baseplate assembly warps, vertical arms will not be parallel. Make corrections by
shimming at appropriate locations. To help prevent warping, tighten the eight carriage bolts to 28 ft.
lbs. in the following sequence:
3, 8, 1, 2, 4, 5, 6, 7, 9, 10
NOTE:
Vertical arms must be parallel for proper operation. Adjust bolts as required. Best results are obtained
when lift is mounted on plywood. Shims, although best avoided, may be used if required.
