Check the machine body oil strainers and filters, if any obstruction should be promptly removed. Crude oil filter using copper wire mesh.
4, manual greasing requirements of the machine refer to (Figure IV)
5, Always check the electrical system for loose joints, fever, contact burning and so on. Tighten the plate bolts, repair or replace the contact.
6, Take minor repairs every six months from the production date and overhaul once a year.
