关于新买的产雪机

[birdfly]

新买的产雪机, 已加了机油和汽油, 但在第一次往前推的时候不停的发出 z......z......z 的声音,请问谁有经验知道是怎么回事儿吗?
谢谢!

检查下Throttling.

打火时Throttling开到最大,进油气最多,易于点火,

一但开始吃雪时, 就要Throttling最小, 控制燃暴增加功率.

不灵就要试试其他原因了.

Where is it came from , engine or scrach the driveway.

I think the z....z....z.... is the sound coming out from the auger-the spiral cutting blad. The auger is only supported with two copper bush bearings on two side.

The sound can also coming out from the wheel drive assembly (the clutch assy). There's a small rubber wheel running on a larger metal disc, the control of the wheel speed is by positioning the small rubber wheel running on the metal disc, the snowblower will move slowly when the small rubber wheel is close to the center of the disc...it could generate the z..z... sound as well.

In both cases, this is normal.
