• Avoid personal injury. Use a chain hoist, or get assistance, when lifting components that
weigh
50
lb. (23 kg) or more. Make sure all lifting devices (chains, hooks, or slings) are
in good condition and are
of
the correct capacity. Make sure hooks are positioned
correctly. Always use a spreader bar when necessary. The lifting hooks
must not be
side loaded.
•
To
avoid burns, be alert for hot parts on components that have just been turned off.
• Always use tools that are in good condition. Make sure you understand how to use them
before performing any preventive maintenance work.
• Use ONLY genuine NLB replacement parts.
• Do not make any unauthorized alterations
to
the equipment or components.
• Do not attempt pressurization
of
the power end with dry gas to exclude contaminants
without a special oil level indicator. With a standard indicator, all oil will be lost
through the vent hole in the top
of
the indicator.
