
If you have the commercial or self-propelled model, also change the oil filter at this time. See the next page.

Be certain to fill with oil before starting the engine. See page 10.
NOTE: The new Wheel will have a red Sleeve inside the Hub. This Sleeve keeps the Wheel Splines in place during shipment. As the
Wheel moves onto the Axle, the Sleeve will push out of the Wheel Hub. You can then remove and discard the Sleeve.
8. Install the Axle Nut and tighten it firmly. The installation is now complete.
NOTE: You have properly installed the Wheel when the Wheel locks against the Axle when you pull the Trimmer backward, and will
freewheel when pushed forward. The design of the Wheel Bearings is to be directional.
9. Repeat steps 2 through 8 for the opposite Wheel.

the Wheel Clutch Cable.

stop the engine, wait five (5) minutes to allow parts to cool and disconnect
the spark plug wire, keeping it away from the spark plug.
