2 Check the water cooler and accessory hoses for kinks, internal obstructions or block- age, or ruptures. If such problems were found then correct them and turn the machine off and on to check if the beeping has been elimi- nated.

3.Check the water cooler fluid level. Low coolant level could cause the flow rate to drop.

4.Prime the water cooler. Refer to the Setup Overlay section of this manual for instructions.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, con- tact your local authorized Lincoln Electric Field Service Facility for technical assistance.
