Show/hide table

Personal injury or death can result from machine articulation or movement. Machine frames can move and a person can be crushed. Connect the steering frame lock between the front and rear frames before working on the machine. Before operating the machine, place the steering frame lock in the stored position. Failure to place the steering frame lock into the stored position before operating can result in loss of steering.

Failure to follow the instruction below for the installation of the steering frame lock pin may result in personal injury. Special care must be taken if more than one person is installing the steering frame lock pin. Confirm the verbal communication and the hand signals that will be used during the installation. Be alert for the sudden movement of the machine frames or the steering frame lock pin. Do not insert fingers into the steering frame lock bores when the bores are being aligned. Do not stand on the machine or within one meter of the machine while the steering control is moved in order to allow the steering frame lock pin to move into the fully installed position.

Install the steering frame lock when the machine is being lifted and when the machine is being transported. Also install the steering frame lock if you are performing service work near the articulating hitch.

The steering frame lock is located at the articulating hitch in the center of the machine.

1. Move the machine to a hard, level surface. Park the machine in the straight ahead position and engage the parking brake.
