SECTION 6 – SET-UP INSTRUCTIONS CABLE AUTO-FOLD (20 Ft. Hitches)
CABLE AUTO FOLD, 20 Ft. Hitch
Refer to Fig. 29 and follow these steps:
PIVOT MOUNTING BRACKETS
AND CABLE FOLD ARMS
Mount the left and right pivot mounting brackets to the out-
side of the hitch frame against the welded stops. Secure
with 5/8” U-bolts, lock washers and nuts – do not completely
tighten.
Attach the left and right cable fold arms to the mounting brack-
ets and secure with 1-1/4” x 14” pins, bolts, flatwashers and
locknuts.
LOCK ASSEMBLY AND HYDRAULIC CYLINDER
Attach Auto-Fold lock with 1” bolt and bushing. Install hy-
draulic cylinder. Adjust pivot mount brackets and hydraulic
cylinder rod end clevis so Auto-Fold lock fully engages over
Auto-Fold arms when the cylinder is retracted. Also check
that the Auto-Fold arms do not bind when lifted into transport
position. If Auto-Fold does not release, adjust the 3/4” x 2-1/
4” bolt and jamnut (Ref. 25 & 28) to provide clearance be-
tween the guide (A) and the hitch tube. Tighten 5/8” U-bolts
on pivot mounting brackets when adjustments are complete.
TENSION SPRINGS
Attach tension springs with 3/4” eyebolts and locknuts.
Tighten eyebolts on long springs (8C1940) until the spring
coils begin to separate. Tighten eyebolts on lock spring
(8C1950) 1/4” past the point that the spring coils begin to
separate.
HYDRAULIC SYSTEMS
Assemble hoses and fittings as shown.
The Auto-Fold warning decals must be clearly visible to the
operators. The Auto-Fold arms must rest on the hitch frame
while the hydraulic cylinder is being retracted. If Auto-Fold
arms do not rest on hitch frame, back up machine further or
readjust if necessary.
