Working On Slopes; Unauthorized Operations - Komatsu PC27R-8 Operation & Maintenance Manual

PRECAUTIONS TO BE TAKEN WHEN WORKING

2.4.6 WORKING ON SLOPES

When working on slopes, if possible avoid rotating the upper
structure, since the machine may lose balance and overturn.
It is particularly dangerous to swing on slopes when the bucket
is full.
If these operations must last longer, accumulate soil in such a
way as to create a horizontal platform on which the machine
can be positioned.

2.4.7 UNAUTHORIZED OPERATIONS

Do not dig under overhangs.
The protruding surface, in fact, may collapse on the machine.
Do not dig too deeply under the front part of the machine,
since the ground may collapse and cause the machine to fall
down.
