Filling the bucket
There are two basic methods of filling a bucket from a pile: arc penetration and step penetration. Judge the type of
penetration needed for loading and vary the methods to suit the materials.
Arc penetration
With the arc penetration method, the bucket is forced into the pile and rolled back while raised in a continuous upward
arc until the bucket is filled. When using this method, remember that too much roll back may over load the lift system.
When activating both the lift and bucket hydraulic systems at the same time, the lift system may occasionally stall.
When this happens, disengage either the lift or roll back function to allow maximum hydraulic force to act upon one
set of cylinders.

Step penetration
With the step penetration method, the bucket is forced into the pile at ground level with the bucket bottom horizontal.
Force the bucket into the pile as far as possible during the initial thrust. Raise the bucket about
0.3 m ( 1 ft ) and then
force it further into the pile. Repeat this cycle as many times as necessary to fill the bucket.
