WARNING
: Hot melt materials can cause severe burns
resulting in disfigurement or blindness. Take the
following precautions before beginning any
maintenance:
•
Wear protective clothing, safety goggles, and safety
gloves.
•
Turn pump motor switch off position. Depressurize
applicator(s) by triggering.
•
Unless stated otherwise, always allow melt unit to
cool before beginning any maintenance.
•
Disconnect hose electrical connector when hose
fittings are disconnected and power is off.
CAUTION
: To prevent damage to components (hose
fittings, etc.), heat part(s) being serviced to
approximately 121 °C (250 °F) prior to dismantling,
assembling, or adjusting. Heat parts by applying power
to the unit using a hand held hot air gun or placing parts
on a hot plate. Failure to do this will result in stripped
threads and ruining both parts and tools.
CAUTION
: To avoid arcing of electrical contacts and
possible failure of components, do not connect
electrical connectors when the hose power switch is on.
