Restricted Operation
CAUTION
• Use caution when operating work equipment
while the machine is traveling.
• When the engine auto idle is on, moving any
control lever increases the engine speed.
• Avoid sudden stops when operating work
equipment. Hydraulic shock can damage the
hydraulic system.
• Avoid any working conditions that may cause the
machine to tip over.
• Avoid moving any control lever or pedal to
abruptly change the direction of the machine.
• Do not operate the machine on any ground that
lacks sufficient support.

scraping, digging, etc., with the hydraulic
cylinder fully extended.
Failure to follow these precautions could result in
injury or damage to the machine.
