1. With the bucket installed, lower it into the
ground until the front tires are off of the ground.
2. Stop the engine and remove the key.
3. Turn the front wheel forward on one side of the
traction unit until the top span of the drive chain
is tight.
4. Measure the distance between the bottom of the
chain guard and the lower chain span (Fig. 22).
If the slack in the chain is not within 1–1/2 to
2–1/2 inches, adjust the tension (refer to
Adjusting the Tension).

IMPORTANT: Under sandy conditions, sand
can build up on the sprockets. This enlarges the
sprocket and the chain tightens. Under these
conditions the chains should have 2–1/2 to 3–1/2
inches of slack between the bottom of the chain
guard and the lower chain span.
5. Repeat steps 3 and 4 for the other drive chain.
6. Start the engine and raise the bucket to return the
front wheels to the ground.

IMPORTANT: In sandy conditions, an
additional 1/2 inch of slack may improve chain
performance.
