Remove the Cutting Attachment

The gear housing gets hot with use and can result in injury to the operator. When the unit is turned off it remains hot for a short time. Do not touch the gear housing until it has cooled.

1.Align the shaft bushing hole with the locking rod slot and insert the locking rod into the shaft bush- ing hole (Fig. 3-8).

2.Hold the locking rod in place by grasping it next to the boom of the unit (Fig. 3-9).

3.While holding the locking rod, remove the cutting attachment by turning it clockwise off of the out- put shaft (Fig. 3-10). Store the cutting attachment for future use.

NOTE: The blade retainer under the cutting attach- ment will be used when installing the cutting blade.

Install the Cutting Blade

To avoid serious personal injury, always wear gloves while handling or installing the blade.

4.Place the cutting blade on the output shaft bushing (Fig. 3-11).

5.Make sure that the cutting blade is centered on the pilot step and sitting flat against the output shaft bushing (Fig. 3-12).

If the cutting blade is off-center, the unit will vibrate, and the blade may fly off, which can cause serious personal injury.
