3.2INSTALL DRIVE WHEELS.

3.2.1Mount 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.

3.3CHECK TIRE PRESSURE.

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

3.4INSTALL SEAT RETAINING ROD.

3.4.1Tilt 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.

3.5INSTALL MOTION CONTROL LEVERS.

3.5.1Loosen 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.
