Self-Leveling
Feature
The self-leveling feature
maintains the attachment
tilt angle as the lift arm is
raised/lowered (Fig. 39)
AL 500 Series Limited
Self-Leveling
Without self-leveling, unintentional dumping
(tilting forward) of the attachment can occur
when the lift arm is raised or lowered. The pointer on self-level
indicator (B, Fig. 40) must be within in the zone of self-level decal (A)
or the attachment will not maintain the same attachment tilt angle
when the lift arm is raised and lowered.
AL 500 Series machines
use a special lift arm
design to enhance bucket
breakout forces and
improve digging ability.
With this lift arm design,
the tilt cylinder must be
positioned so self-leveling
is maintained.To maintain
self-leveling on AL 500
Series machines, adjust the
tilt cylinder until self-level
indicator pointer is within
the zone of self-level decal
(X).
Use of forks or unapproved attachments may
not allow self-leveling activation due to the
orientation of the All-Tach
®
to the attachment.
