Routine Inspection
In order to use the machine in the optimum condition, it is recommended to perform routine
inspections before loading and changing the material.
Read this section for determining the points and types of inspection.
Checking the operation of discharge damper
Move the discharge damper in the direction indicated by arrow, to make sure that the damper
returns to the original position.
Make sure that the circuit protector is not activated. (Refer to Section 1.2.1, Table 2 No. 14.)
If the circuit protector is activated,
discharge operation is disabled. (Refer
to Section 4.2.2
Troubleshooting B.)
Normal status
When the circuit protector is
activated
Checking operation with a test piece (*1)
To check the detection sensitivity, confirm that a test piece will be discharged to the discharge
chute properly.
If the test piece cannot be discharged properly, contact SAIKA.
(*1): Test pieces are optional.
Important
In order to prevent the test piece being lost in the line or mixed with the
material, provide a protection to the discharge port.
Checking the cooling fan operation
Ensure that air flows out from the cooling fan.
If the cooling fan does not blow air, or if the fan abnormally sounds, it needs replacement.
If cooling fan replacement is required, contact us.
