After-sales visit Yifeng old customers

Recently, several problems were found in the three-pack service process of Yifeng's old customers to remind everyone to pay attention: Four years ago, the machine basically had loose bolts, aging lines, and slippage of the triangle belt. Some air filters did not know how to add oil and did not need diesel to clean them. The trenching blade was reversed, the gearbox was refueled too much, and even the entire diesel engine fell off and was still in use. Thank you for your trust in Yifeng Machinery, but you must maintain it in time!Thank you again for your valuable suggestions from Yifeng's old customers. If you have any questions, please call 400-1876-816, and the after-sales service hotline is 173 6206 7431. Thank you.
