Installation of blade guard (Fig. 9, 10)

NOTE

The guard bracket may come already mounted to the gear case on some models.

Install the blade guard on drive shaft tube against angle transmission. Tighten the guard bracket firmly so that the blade guard does not swing or move down during operation.

Install the blade guard to the guard bracket, which also secures the guard to the gear case using the two guard mounting screws.
