Maintenance Instructions | REPLACING/REPAIRING |
Drive Chain
The drive chain should be replaced if, when adjusted properly, it can be pulled away from the front of the auger sprocket more than 1/2 of the height of a tooth on the sprocket. Running the snowblower with a worn chain increases wear on the sprock- ets.
1.Remove the chain guard cover and the LH au- ger guard. Refer to LUBRICATION of Drive Chain in this section for removing chain guard cover.
2.Loosen the chain tension block mounting nut and bolt. Position the chain tension block so the chain has as much slack as possible. Tighten the chain tension block mounting nut and bolt slightly to hold the chain tension block in this position.
