CALIFORNIA
Proposition 65 Warning
Use of this product may cause exposure to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
Safety
Danger
There may be buried utility lines in the work area. Digging into them may cause a shock or an explosion.
Have the property or work area marked for buried lines and do not dig in marked areas. Contact your local marking service or utility company to have the property marked (for example, in the US, call 811 or in Australia, call 1100 for the nationwide marking service).
General Safety
Always follow all safety instructions to avoid serious injury or death.
-
Do not exceed the rated operating capacity, as the machine may become unstable, which may result in loss of control.
-
Do not transport an attachment with the arms raised or extended (if applicable). Always transport the attachment close to the ground; refer to Transport Position.
-
Have the property or work area marked for buried lines and other objects, and do not dig in marked areas.
-
Read and understand the content of this Operator’s Manual before starting the machine.
-
Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.
-
Never allow children or untrained people to operate the machine.
-
Keep your hands and feet away from the moving components and attachments.
-
Do not operate the machine without the guards and other safety protective devices in place and working on the machine.
-
Keep bystanders and pets away from the machine.
-
Stop the machine, shut off the machine, and remove the key before servicing, fueling, or unclogging the machine.
Improperly using or maintaining this machine can result in injury.
To reduce the potential for injury, comply with these safety instructions
and always pay attention to the safety-alert symbol 
, which means Caution, Warning,
or Danger—personal safety instruction. Failure to comply with
these instructions may result in personal injury or death.
Slope Safety
-
Operate the machine up and down slopes with the heavy end of the machine uphill. Weight distribution changes with attachments. An empty load-bearing attachment makes the rear of the machine the heavy end, and a full load-bearing attachment makes the front of the machine the heavy end. Most other attachments make the front of machine the heavy end.
-
Raising or extending (if applicable) the loader arms on a slope affects the stability of the machine. Keep the loader arms in the lowered and retracted position when on slopes.
-
Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope or uneven terrain requires extra caution.
-
Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.
-
Slow down and use extra care on hillsides. Ground conditions can affect the stability of the machine.
-
Avoid starting or stopping on a slope. If the machine loses traction, proceed slowly, straight down the slope.
-
Avoid turning on slopes. If you must turn, turn slowly and keep the heavy end of the machine uphill.
-
Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.
-
If you feel uneasy operating the machine on a slope, do not do it.
-
Watch for holes, ruts, or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.
-
Use caution when operating on wet surfaces. Reduced traction could cause sliding.
-
Evaluate the area to ensure that the ground is stable enough to support the machine.
-
Use caution when operating the machine near the following:
-
Drop-offs
-
Ditches
-
Embankments
-
Bodies of water
The machine could suddenly roll over if a track goes over the edge or the edge caves in. Maintain a safe distance between the machine and any hazard.
-
-
Do not remove or add attachments on a slope.
-
Do not park the machine on a hillside or slope.
Bucket Safety
-
Always lower the attachment and shut off the machine each time you leave the operating position.
-
When lifting the attachment, keep it level and prevent the load from spilling backward.
Maintenance and Storage Safety
-
Check fasteners at frequent intervals for proper tightness to ensure that the equipment is in safe operating condition.
-
Refer to this Operator’s Manual for important details if you store the attachment for an extended period of time.
-
Maintain or replace safety and instruction labels, as necessary.
Safety and Instructional Decals

Maximum Material Density at Capacity
The density of the materials moved by the bucket varies and, therefore, so does the amount of material that the bucket can carry before reaching the maximum load rating. The first table lists the density of material that can be carried, both heaped and struck (i.e., leveled off), in the bucket. The Material Density table lists common materials and their densities.

Operation
Determine the left and right sides of the machine from the normal operating position.
Installing and Removing the Attachment
Refer to the Operator’s Manual for the traction unit for the installation and removal procedure.
Important: Before installing the attachment, position the machine on a level surface, ensure that the mount plates are free of any dirt or debris, and ensure that the pins rotate freely. If the pins do not rotate freely, grease them.
Note: Always use the traction unit to lift and move the attachment.
Warning
If you do not fully seat the quick-attach pins through the attachment mount plate, the attachment could fall off the machine, crushing you or bystanders.
Ensure that the quick-attach pins are fully seated in the attachment mount plate.
Filling the Bucket
-
Position the bucket level to the ground.
-
Drive forward and insert the bucket into the pile of material.
-
When the bucket is full, drive the machine in reverse and gently tilt the bucket rearward to decrease the lifting resistance when you lift the load.
Important: Always carry loads close to the ground; refer to Transport Position.
Transport Position
When transporting a load, keep the attachment as close to the ground as possible, no more than 15 cm (6 inches) above the ground. Tilt it rearward to keep the load level.
Storage
-
Before long-term storage, wash the attachment with mild detergent and water to remove dirt and grime.
-
Paint all scratched or bare metal surfaces.
Note: Paint is available from your Authorized Service Dealer.
-
Store the attachment in a clean, dry garage or storage area. Cover it to protect it and keep it clean.
