9.1 Maintenance Safety
• Good maintenance is your responsibility. Poor maintenance
is an invitation to trouble.
• Read and understand all of the information in the Safety
section that starts on page 8 .
• Follow good shop practices that include, but are not limited
to the following:
-
Keep the service area clean and dry.
-
Ground electrical outlets and tools correctly.
-
Make sure that there is an adequate amount of light for
the current task.
• Never operate the tow vehicle in a closed building. The
exhaust fumes may cause asphyxiation.
• Never work underneath equipment unless it is securely
supported by blocks.
• Always wear the appropriate PPE.
• When replacement parts are required, only use genuine
original equipment manufacturer (OEM) parts. Bush Hog
cannot be held responsible for damage or injuries that are
caused by use of unapproved parts or accessories.
• Inspect and tighten all bolts, nuts, and screws.
• Reinstall all safety shields and covers after completing
service or maintenance.
• Use regular cleaners to clean parts. Do not use gasoline.
• Always use the correct tools for the task, make sure that
the tools are in good condition, and understand how to use
them.
• Have a qualified tire dealer or repair service complete all
required tire maintenance. Do not attempt to mount a tire
unless you have the proper equipment and experience for
this task. Failure to follow the correct procedures when
mounting a tire on a wheel or rim can cause an explosion,
which may result in serious injury or death.
• When replacing worn tires, make sure that they meet the
original tire specifications. Never undersize a tire.
