Backhoe Operation
Fig. 4-35
0004373
Backhoe operation is for digging an area lower than the
machine. The digging range of the arm is 30° and 45°. The
angle may vary according to the digging depth.
Maximum digging force can be obtained when the angle
between the boom and the arm and the angle between the
bucket cylinder and the bucket bracket are both at 90°.
WARNING!
• Contact the site supervisor before any digging to make sure that all underground hazards
have been located.
• Never allow any personnel within the work area of the machine while it is being operated.
• Avoid moving any control lever or pedal to abruptly change the direction of the machine.
• Avoid sudden stops when lowering the boom. Hydraulic shock could damage the hydraulic
system.
Failure to follow these warnings could result in death or serious injury.
