Illustration 1	g00101105

The bulldozer blade can be positioned in several angles. Position (1) is the extended position. Position (2) is the neutral position. Position (3) is the retracted position.

1. Lower the bulldozer blade to the ground. Place the control for the lift cylinder in the FLOAT position.

2. Actuate the tilt cylinder in order to remove all force from the tilt brace. The rear pin between the tilt brace and the push arm must be loose. The rear pin must move freely. Stop the engine.

3. Place wooden strips under the edges of the tabs of the tilt brace. Maintain the holes in the tilt brace and the push arm bracket at the same elevation. Reassembly will be easier.

4. Remove the retainer bolts, the retainer, and the pin at the tilt brace in order to move the push arm. Start the engine.

Keep fingers clear. Do not place your fingers into the pin holes in the tilt brace and/or push arm bracket at any time during the adjustment procedure.

5. In order to slide the tilt brace forward, actuate the tilt cylinder. In order to slide the tilt brace rearward, actuate the tilt cylinder. If you extend the tilt cylinder, the brace will slide forward. If you retract the tilt cylinder, the brace will slide rearward.

6. Stop the engine. Align the holes in the tilt brace and in the push arm bracket. Reassemble the pin, the retainer, and the bolts in the desired location.
