OPERA

T

ION

OPERATING WITH FLOAT CONTROL

During hard surface operation, keep bucket level
and put lift control in float position to permit
bucket to float on working surface. If hydraulic
down pressure is exerted on bucket, it will wear
faster than normal.

Float will also prevent mixing of surface material
with stockpile material. Float position will reduce
the chance of surface gouging when removing
snow or other material. 

LOADING FROM A BANK

Choose a forward gear that provides sufficient
ground speed for loading.

Exercise caution when undercutting high banks.
Dirt slides can be dangerous. Load from as low
as possible for maximum efficiency. Loader lift
and breakaway capacity diminish as loading
height is increased.
