UNLOADING & ASSEMBLY
INSTALL TONGUE
IMPORTANT: If there is more than one machine to
be assembled, and they are different sizes (12 ft.,
14 ft., 16 ft.), be sure the proper tongue is matched
to each unit. Tongues are identified on a plastic
tag tied to the hose support near the front end.
Should this tag be missing, tongues can be
identified by length as follows:
HEADER SIZE TONGUE LENGTH *
12 ft. 17' 7" (5360 mm)
14 ft. 19' (5780 mm)
16 ft. 21' 7 1/2 " (6590 mm)
* Tongue length is measured from center of pivot
hole at back end to center of hitch pin hole at
front end.
1. Ensure plastic bushings are installed in pivot
hole at back end of tongue. Remove shipping
wire.
NOTE: The two shorter bushings (A) install
from top of tongue, the longer one (F) from the
bottom.
2. Install jack in working position at front of
tongue.
3. Attach chain from lifting vehicle or hoist to
tongue as described on page 69. Lower tongue
(B) onto pivot pin. NOTE: Use the jack to adjust
the pitch of the tongue for proper alignment
when installing onto pivot pin.
4. Install retainer (C) on top of tongue, over pivot
pin bolts (D).
5. Install two 5/8 lock nuts (E) and tighten to 160
ft.lbs. (215 N ⋅m).
6. Remove lifting brackets from tongue when
complete.
INSTALL WHEELS IN FIELD POSITION
1. Raise rear of machine and move wheels from
shipping position (A) to field position (B).
NOTE: For 12 ft. unit (both wheels) and 14 ft.
unit (left wheel only), remove spindle retaining
bolt and nut (C) and slide spindle outboard until
clearance to vertical float spring is adequate for
wheel removal from spindle. When reinstalling
wheel bolts, torque to 120 ft.lbs. (160 N ⋅m)
2. Torque the 1/2 inch lock nut (C) to 80 ft.lbs.
(110 N ⋅m).
3. Lower machine onto the tires.
