12. Remove the Hitch Pins of the Rear Stabilizers and rotate them into their
upright position until the holes are aligned (Figure 27).
13. Reinstall Hitch Pins into the Rear Stabilizers and secure with the Lynch Pins.
14. Close the Latch Assembly on the Tow Hitch Assembly to lock the Tow Hitch
Assembly onto the Tow Ball (Figure 28). Attach the towing Safety Chains to
the tow vehicle ensuring there is enough slack for turning.
15. Make sure the hitch coupler is properly and securely attached to the tow ball.
16. Insert the Locking Pin into the hole of the Latch Assembly to lock it in the
closed position (Figure 29).
17. For extra safety and security, you may want to purchase a lock to install into
the hole of the latch assembly.
Hitch Coupler Adjustment Check
1. Place the proper size ball in the socket of the coupler and close the latch
assembly (Figure 30). Verify that the locking trigger is properly engaged in its
detent.
2. Pull on the ball and/or coupler, trying to remove the ball from the socket. If
the ball moves more than 1/16" in the coupler’s socket, the clamp requires
adjustment. Follow the proper adjustment procedure in the following steps.
Hitch Coupler Adjustment
1. With the proper size ball in the socket of the hitch coupler, close the latch of
the coupler completely (Figure 31). Verify that the locking trigger is properly
engaged in its detent.
2. Tighten the lock nut on the underside of the coupler until the spring
between the nut and the clamp is fully compressed. Then back off the lock
nut 1/2 turn or just enough that the latch is able to clamp and unclamp from
the ball.
Making sure the backhoe is securely attached to the vehicle is the responsibility
of the owner/operator. Failure to securely attach the backhoe can cause loss of
control of the vehicle or the backhoe being separated from the towing vehicle,
resulting in serious injury or death. ALWAYS use accessory lights and devices
when transporting on a road or highway to warn operators of other vehicles.
Check your local government regulations.
