FAQ
Q:How often should gear oil be changed?
A: Oil replacement after each irrigation season is recommended. For year-round heavy continuous operation, change oil every 6 months to prevent oil degradation and internal wear.
Q:What key points should be followed during installation?
A:Clean mating surface of output shaft; fill oil to specified level; keep breather valve unblocked to avoid pressure buildup and oil seepage.
Q:Is frequent forward-reverse switching allowed?
A:Forward and reverse cyclic operation is supported, but frequent rapid direction changes are not advised. Repeated impact accelerates gear wear and shortens service life.
