Ê Hazards During Servicing and Maintenance
SHOCK HAZARD—Electrical power can cause death or severe injury. Lock OFF
and tag out power to the machine main bus at the wall disconnect before serv-
icing. Power switches on machine control panel disable only control circuit
power in certain electrical boxes.
CRUSHING AND ENTANGLEMENT HAZARD—Rotating machinery can entangle
and crush body parts. Lock OFF and tag out power to the machine main bus at
the wall disconnect before servicing.
CRUSHING AND ENTANGLEMENT HAZARD—Rotating machinery can entangle
and crush body parts.
Keep body parts away from exposed rotating motor belts and pulleys during
service procedures.
Limit switches absolutely must function properly to ensure the safe operation of the ma-
chine. INSPECT SWITCHES REGULARLY, AND NEVER OPERATE A MACHINE WITH A
MALFUNCTIONING LIMIT SWITCH.
Ê Additional Hazards During Gas Machine Maintenance
CRUSHING AND ENTANGLEMENT HAZARD—Rotating machinery can entangle
and crush body parts. Keep away from rotating belts and pulleys. Ensure
blower motor belt guard is in place at all times.
EXPLOSION AND FIRE HAZARD—Pilot Gas Pressure/Pilot Gas Flame proce-
dure has potential for gas release. Follow instructions carefully.
Ê Additional Hazards During Steam Machine Maintenance
BURN HAZARD—Hot surfaces will cause severe burns. Lock OFF and tag out
steam flow to machine at an external shut-off valve. Allow piping to cool before
servicing.
DRYERS WITH STEAM TRAPS RATED 85-180 PSI (6-12 ATU) WILL NOT OPERATE PROP-
ERLY BELOW 60 PSI (4 ATU). STEAM TRAPS RATED 160-225 PSI (11-15 ATU) WILL NOT
OPERATE PROPERLY BELOW 115 PSI (8 ATU). These pressure ranges refer only to the
range of pressures through which the trap may be reasonably expected to operate prop-
erly. They are not necessarily an indication of the safe operating pressure for the steam
coil. Always refer to the nameplate for the specific dryer to determine the maximum permis-
sible pressures.
Ê Additional Hazards During Hot Oil Machine Maintenance
BURN HAZARD—Hot surfaces will cause severe burns. Lock OFF and tag out
hot oil flow to machine at an external shut-off valve and allow piping to cool
before servicing.
ELECTRIC SHOCK HAZARD—Machine power is on and positioner covers re-
moved for the calibrating and verifying procedures. Exposed terminals are en-
ergized at 120VAC or greater. You can be killed or severely injured by contact
with these terminals. Do not touch any wire terminals when calibrating or
verifying settings.
