TILLERLUBRICATION

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a

complete stop, disconnect spark plugD wire and move wire away from spark

plug. Remove ignition key on electric start models.

Failure to follow these instructions can result in serious personal injury or prop- erty damage.

CHECKHARDWARE

Besure to check the three end cap mounting screws locatedat the rear of the transmission (Figure 5-2). Lift the tine flap to service those screws.
