  If the exhaust air does not exit the hopper efficiently,
  May not be able to control temperature normally.
  "Upper Limit Alarm" may appear on panel lamp.

(3)
Suction Filter
(travelon filter)
Monthly Remove filter from dryer, blow clean dry air and remove particles.

(4)
U-Bolt
Sensors
Check to see if the U-bolt is securely fitted or if the sensor is deformed or installed on the correct position.
  If the U-bolt is loose, drying air will leak outside. May not be able to control temperature because of this. Temperature may be inconsistent if the sensor is deforming.
(5)
MC-1 Wear
Inspection
(Solenoid contactor)
Every 3 Months Open the control panel to see if black powder is stuck on the surface of the MC-1.
  If the MC-1 is used at a high temperature, this may reduce the life span of the contactor.

Screws, Bolts,
Nuts
Every 6 Months Check looseness of each screw, bolt and nut. Also check the looseness of fitting bolts on the molding units as well as the connections of the drying units.
* Check looseness on any bolt or nuts. Tighten if loose.
  If either the fitting bolts or the connecting bolts are loose, machine may tip over and cause damage.

* For safety purposes, please turn off power of unit when performing inspections.
If the filter is worn or if particles cannot be removed, replace with a new filter.
