The information in this section is written for dealer ser-
vice personnel. The repair described here requires
special skills and tools. If your shop is not properly
equipped or your mechanics are not properly trained in
this type of repair, you may be time and money ahead
to replace complete assemblies.
Never go underneath equipment (lowered to the
ground or raised) unless it is properly blocked and
secured. Never place any part of the body under-
neath equipment or between moveable parts even
when the engine has been turned off. Hydraulic
system leak down, hydraulic system failures,
mechanical failures, or movement of control levers
can cause equipment to drop or rotate unexpect-
edly and cause severe injury or death. Follow Oper-
ator's Manual instructions for working underneath
and blocking requirements or have work done by a
qualified dealer.
Do not allow bystanders in the area when oper-
ating, attaching, removing, assembling, or servic-
ing equipment.
Do not modify or alter or permit anyone else to
modify or alter the equipment or any of its compo-
nents in any way.
Do not disconnect hydraulic lines until machine
is securely blocked or placed in lowest position
and system pressure is released by operating
valve levers.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
Make sure all safety decals are installed.
Replace if damaged. (See Safety Decals section for
location.)
Make sure shields and guards are properly
installed and in good condition. Replace if damaged.
CAUTION
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
