SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Only qualified personnel should perform this maintenance.

•Turn the input power OFF at the disconnect switch or fuse box before working on this equipment.

•Do not touch electrically hot parts.

GENERAL MAINTENANCE

1.The fan motor has sealed bearings which require no service.

2.In extremely dusty locations, dirt may restrict the cooling air causing the welder to run hot with pre- mature tripping of thermal protection. Blow out the welder with low pressure air at regular intervals to eliminate excessive dirt and dust build-up on inter- nal parts.

3.Periodically check the welding cables. Inspect for any slits or punctures. Also make sure that all con- nections are tight.
