3.2 INSTALL DRIVE WHEELS

3.2.1 Mount drive wheels with the valve stem to the outside of the unit. Secure using
four (4) 1/2-20 x 7/8"UNF wheel bolts (installed in hubs) or 1/2-20 wheel nuts
(installed on studs in hubs) for each wheel. Torque to 95 ft-lbs (128 N!M).
NOTE: Earlier models require the UNF wheel bolts. Later models have studs
installed in the wheel hub and require wheel nuts.

3.3 CHECK TIRE PRESSURE.

3.3.1 Check tire pressure in caster and drive tires. Proper inflation pressure for all
four (4) tires is 13 psi (90 kPa). Adjust if necessary.

3.4 INSTALL SEAT RETAINING ROD.

3.4.1 Tilt seat up. Remove 5/16" nylock nut from bolt attaching seat retaining rod to
seat frame. Remove ignition keys attached to bolt. Remove retaining rod from
seat and insert the "L" shaped end of the rod into the hole directly above the
left-side hydraulic pump (the "L" must be positioned to the left or pointing up).
Position the seat retaining rod to the outside of the mounting tab on the seat
frame and secure with 5/16" x 1" bolt and nyloc nut. Tighten until snug, then
loosen just enough so the rod pivots freely.

3.5 INSTALL MOTION CONTROL LEVERS.

3.5.1 Loosen and remove the two (2) 3/8" x 1" bolts and spring disc washers which
attach the motion control levers to the control arm shafts for shipping and the
two (2) 3/8" x 1" bolts and spring disc washers which are screwed into the
control arm shafts.
a) Install the left motion control lever onto the control arm shaft (See Fig 1)
on the left side of the console. Place the lever (with the mounting plate
towards the rear) on the outside of the control arm shaft and secure with
the bolts and washers. Position the lever so the bolts are in the center of
the slots on the lever mounting plate and tighten until snug. Repeat on
opposite side of unit.
