Never Operate with Bucket Force

0002866
Never use the force of the bucket for excavating, digging,
breaking, or pile-driving operations. Such operations may
considerably reduce the service life of the machine.
To avoid cylinder damage, do not use the bucket to strike
or compact the ground.
WARNING!
•
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.
•
Do not attempt work operations such as scraping, digging, etc., with the hydraulic cylinder
fully extended.
Failure to follow these precautions could result in injury or damage to the machine.
