with perforated angle (not supplied). A representative
mounting is shown. (Fig. 9) Connect angle and vibration

and M6 Flanged Head Nuts (2) and secure the hanger
straps to the anti vibration brackets as per the diagrams .
The brackets may have to be pushed lightly on an angle
to allow the bolts to be fitted. Strips should not extend
more than 18mm below centre of drive unit mounting
holes. (Fig. 9).
