General
A thorough knowledge of the operating characteristics
and limitations of the machine is always the first require-
ment for any user, regardless of the user’s experience with
similar types of equipment.
Placards
Important points to remember during operation are pro-
vided at the control stations by DANGER, WARNING,
CAUTION, IMPORTANT and INSTRUCTION placards. This
information is placed at various locations for the express
purpose of alerting personnel of potential hazards consti-
tuted by the operating characteristics and load limitations
of the machine. See FOREWORD for definitions of the
above placards.

surface.
2. Load is within manufacturer’s rated design capacity.
3. All machine systems are functioning properly.
4. Proper tire pressure exists in the tires.
