7.1 Safety Considerations
Before attempting any repair work, review
these safety steps and precautions to protect
yourself and the unit.
• Safety should be the primary concern of
anyone performing repair work on the
unit.
• Except where specically directed, make
sure the power is turned OFF at the main
disconnect switch.
WARNING
Always use extreme caution
when performing any repair
procedure requiring the unit
to be operating.
Take every precaution
to keep hands and loose
clothing from coming into
contact with any of the
moving rolls or
other moving parts.
Serious Injury Could Result.
Whenever the unit is running,
one person should be ready
at a red safety STOP button
at all times to stop the unit
if necessary.
• Only work on the unit when it has been
completely cooled down. For more
information, refer to Shut-Down on
page 3-11.
• Make sure the TEMPERATURE control
dial is set to OFF.
• All maintenance procedures should
be handled by at least two qualied
persons. Using the “buddy system”
facilitates a quicker procedure and
decreases the risk of an accident.
• Always keep hands and clothing away
from the moving parts of the machine
when it must be running to make repairs
or adjustments.
• Never bypass any of the unit’s safety
features. Only operate the unit with
endframe doors and all guards in
place and all safety features operating
correctly.
• Never stand, sit, or kneel on a receiving
shelf.
• Your site should have lockout/tagout
procedures in place that comply with
government standards for performing
maintenance and repair. Ask your
supervisor for specic information.
• The JOG REVERSE button remains
powered even when one of the safety
interlock switches is open. This keeps it
available for emergency use. It is very
important that the unit is properly tagged
according to the site’s government-
approved procedures whenever repair
work is being done.
