Precautions on Operating Attachments
WARNING
Long attachments reduce machine stability. When traveling down steep slopes or
slewing on slopes, the machine may loose its balance and tip over.
The following operations are particularly dangerous. Do not perform them.
�
When heavy attachments are installed, the overslew (the distance from where the
operation to stop slewing is performed until slewing stops completely) increases
and mistakes in judgment may result in the attachment hitting surrounding objects.
Allow for plenty of room between the attachment and obstacles.
In addition, the natural drop (the gradual dropping of the attachment under its own
weight when it is stopped in midair) also increases when heavy attachments are
installed.
�
The machine can tip over more easily in the lateral direction than in the longitudinal
direction.
• Do not slew (swing) sideways with excessive weight at the front. In particular do
not slew sideways on slopes.
• The front is heavier for machines equipped with breakers, crushers or telescopic
arms than for machines equipped with the standard bucket. Do not operate such
machines sideways, especially with the digging arm (boom) downhill.
�
When a long arm or a telescopic arm is installed, the operating range suddenly
increases and mistakes in judgment may result in the attachment hitting surrounding
objects. Allow for plenty of room between the attachment and obstacles.
�
Install a swing stopper when a bucket wider than the standard bucket, long arm and
telescopic arm is installed and when using a cab version.
