INTERLOCK SYSTEM
The interlock system prevents the grinding motor and spin motor from running unless the door safety
switches are engaged.
NEVER OPERATE EQUIPMENT WITH THE INTERLOCK SYSTEM DISCONNECTED OR
MALFUNCTIONING. NEVER DISCONNECT OR BYPASS ANY SWITCH OR GUARDING.
To verify the interlock system is working correctly, perform the following test procedure:
1.
Remove the grinding wheel.
2.
Close all doors and start the grinding motor.
3.
With the grinding motor running, open the doors.
4.
If the grinding motor continues to run, shut off and unplug the machine. Contact a qualified technician
to service the machine.
5.
With the spin motor not connected to a cutting unit, close all doors.
6.
Start the spin motor.
7.
With the spin motor running, open the door.
8.
If the spin motor continues to run, shut off and unplug the machine. Contact a qualified technician to
service the machine.
DO NOT USE COMPRESSED AIR TO CLEAN GRINDING DUST FROM GRINDER.
LOW VOLTAGE RELAY
The grinder is equipped with a high-low voltage monitor which is factory preset
at 100-140 VAC. If the voltage inside the control panel falls outside of the range of
100-140 VAC under load, the relay will open and trip out the magnetic starter. If
this occurs, your power supply line is inadequate to run this machine and must be
corrected before proceeding further with the grinder.
DAILY INSPECTION
THE DAILY INSPECTION SHOULD BE
PERFORMED ONLY WHEN THE MACHINE IS
OFF AND ALL MOTORS HAVE STOPPED.
1.
Perform a visual inspection of the entire unit. Look
for signs of wear, loose hardware, and missing or
damaged components. Ensure connections are tight
and hoses and tubes are in good condition.
2.
Clean the machine by wiping it off.
3.
Remove all grinding grit from the grinding head and
bellows area.
4.
Contact your company's maintenance department if
damaged for defective parts are found
