2. Raise the lift arms and carrier frame fully.
3. Press down on one end of the carrier frame until the up
stop on the opposite end contacts the underside of the
foot step (Fig. 4). The distance between the up stop and
the underside of the foot step, on the end pressed down,
should be approximately 1/4 in. (6 mm). If the distance
is not 1/4 in. (6 mm), an adjustment to the lift cylinder
is required. If the distance is correct, remove the carrier
frame and proceed with the setup instructions.
4. If an adjustment to the lift cylinder is required, proceed
as follows:
A. Remove the clevis pin securing the rod end of the
lift cylinder to the lift arm (Fig. 4).
B. Loosen the hex nut securing the clevis to the
cylinder rod.
C. Rotate the clevis end in or out until 1/4 in. (6 mm)
clearance is attained. Check the adjustment and
repeat steps 2–3 as required.
D. Tighten the hex nut and connect the cylinder rod end
to the lift arm (Fig. 4).
