3.3.10 Working with the wheel loader
Saving the tyres
When digging in piles of soil or blasted rock, the tyres may
become cut by slipping. This reduces the service life of the tyres.
Use the following guidelines to prevent tyre slip:

Keep the ground in the working are level, and remove any
fallen rocks.

Always drive into the stockpile in a straight line. This yields
the greatest digging force and lowest tyre wear.

Drive slowly when clearing away stockpiled material or load-
ing blasted rock (speed range 1).

When digging, raise the bucket when entering the stockpile.
This increases the load on the front wheels, prevents the
front wheels from slipping, and reduces tyre wear.

Lower the bucket to the ground slowly. If the bucket hits the
ground, the front tyres will come off the ground, and the tyres
will slip.

To prevent the front wheels from slipping, they should press
into the ground as much as possible. Therefore, slightly
raise the bucket as soon as it enters the stockpile.
