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.
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed
within a few hours by a doctor familiar with
this form of injury; otherwise, gangrene may
result.
• Ensure that all hydraulic-fluid hoses
and lines are in good condition and all
hydraulic connections and fittings are tight
before applying pressure to the hydraulic
system.
• Keep your body and hands away from
pinhole leaks or nozzles that eject
high-pressure hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks; never use your hands.
