User Manual

7. Lubricate yokes in head support (27) with heavy oil or chassis grease.

8. Install outer tubular handle (35) over solid inner handle (17) and pin together with cotter pin (34). Bend cotter pin to hold in place.

9. Place head assembly (26) into yokes in head support (27) and secure with two short pull pins (23), with grooved end toward

tailgate of truck. Install spring cotter pins (12) into grooves in pull pins.

BEFORE EACH TRIP:

1. Lubricate skid plate surface of the hitch (see figure on cover of Manual) with automotive type chassis grease or use a plastic lube

plate to provide a lubricated surface. Use engine oil to lubricate pivot points of moving parts within the hitch.

2. Plastic lube plates can be used to avoid messy grease. The plastic lube plate must not exceed 3/16 of an inch in thickness to

ensure hitch will operate properly. Lube plates must be 10 inches in diameter or larger to properly distribute king pin weight.

3. Before each trip or maneuver, operate the handle and check that the locking bar opens and closes freely without trailer attached.

4. See that all hitch pull pins (# 11 on Fig. 19) are in place and the spring retaining pins (#12 on Fig. 19) are installed.

WRONG

1. Place blocks (sometimes called “chocks”) firmly against front and rear of each trailer wheel to prevent any possible forwardor

rearward motion. DO NOT REMOVE BLOCKS UNTIL EACH OF THE FOLLOWING STEPS AND THE PULL TEST

HAVE BEEN

COMPLETED. Lower tailgate if necessary.

2. Using trailer jacks, adjust trailer height following the directions in the trailer manual so that bottom of trailer pin box (“A” in Fig. 6)

is ½ to 1 inch below skid plate (See “B” in Fig. 8). During the hitching maneuver, the bottom of the trailer in box should come in

contact with skid plate ramp (“C” in Fig. 8).

WARNING:

Failure to follow this instruction may result in king pin being too high and coming to rest on top of closed

locking bar or not completely inside locking bar. (See Fig. 9). This could result in trailer separating from hitch.

Trailer separation may result in death or serious injury if anyone is under the trailer or between truck and

trailer when separation occurs.
