Use Lifting Equipment Safely
!
WARNING
• Always use a lifting device with a lifting capacity
greater than the weight of the item being lifted.
• Secure the load to the lifting device using cables,
chains, or slings rated to handle the load being lifted.
Fasteners being used to connect lifting devices must
be strong enough to handle the load. Also be sure
the mounting point of load is strong enough to handle
the load.
• When using a lifting device, always connect the load
so it is balanced.
• Always use a lifting device on a hard, level surface.
• Lower the lifting device to the lowest point before
moving. Move the load slowly.
• Always support the load as soon as possible; never
leave a load suspended in mid-air.
Support Machine Securely

WARNING
Use Compressed Air and Air
Tools Safely
!
WARNING
• Compressed air is a useful tool when used in a safe
manner.
• Always use eye and ear protection while using
compressed air and air tools.
• When using air tools, do not exceed the air pressure
rating for the tool.
• When using an impact wrench, always use approved
impact sockets. Never use standard sockets on an
impact wrench.
• Disconnect the air supply before changing air tool
attachments.
• Never point air nozzles or air tools at another person.
• Always maintain air tools properly.
• Permanent damage to the turbocharger may
occur if the engine is shut down without
allowing the turbocharger time to cool.
• To prevent damage, operate the engine with
no load and at half throttle for 3 to 5 minutes
before shutting off engine.
Always check the lifting capacity and condition of
hoists, slings, cables, or chains before use.
Using underrated or worn lifting components can
result in death or serious injury.
• Support the machine using properly rated
jackstands. Never work under a machine
supported only by a jack.
• Do not use wood or concrete blocks to
support the machine. Failure to properly
support the machine may result in death or
serious injury.
Always wear approved eye and ear protection
while using compressed air. Misuse of
compressed air could result in death or serious
injury.
• When using air nozzles, air pressure should
not exceed 30 psi (206.8 kPa).
• Never direct air nozzles or tools at a person.
• Never point air nozzles directly at skin.
