• NEVER stand or sit where you could slip or stumble
into the conveying system while working on it.
• DO NOT wear loose clothing or jewelry, which can
be caught while working on the conveying system. In
addition, cover or tie back long hair.
• Clean the conveying system and surrounding area DAILY, and
inspect the machine for loose, missing or broken parts.
• Shut off power to the conveying system when it is not in use.
Turn the switch to the OFF position, or unplug it from the

2-7 Maintenance Responsibility
Safety is essential to the good health of both operator and machine.
If you are a maintenance worker, you must make safety a priority
in order to effectively repair and maintain equipment.
BEFORE REMOVING, ADJUSTING, OR REPLACING
PARTS ON A MACHINE, REMEMBER TO DO THE
FOLLOWING:
• TURN OFF all air and electric supplies and all accessory
equipment at the machine.
• DISCONNECT AND LOCK OUT electrical and pneumatic
power, and attach warning tags to the disconnect switch and air
shutoff valve.
When you need to perform maintenance or repair work on the
conveying system above floor level, use a solid platform or a
hydraulic elevator. If there is a permanently installed catwalk on
your conveying system, use it. The work platform should have
secure footing and a place for tools and parts. DO NOT climb on
machines or work from ladders.
If you need to repair a large component, use appropriate handling
equipment. Before you use handling equipment (portable “A”
frames, electric boom trucks, fork trucks, overhead cranes) be sure
the load does not exceed the capacity of the handling equipment or
cause it to become unstable.
Carefully test the condition of lifting cables, chains, ropes, slings,
and hooks before using them to lift a load.
Be sure that all non-current carrying parts of electrical apparatus,
electrical component enclosures, and the conveying system frame
