Set-Up
Tires
The tires on your tiller may be over-inflated for shipping
purposes. Reduce the tire pressure before operating the tiller.
Recommended operating tire pressure is approximately 20
p.s.i. (check the sidewall of the tire for the manufacturer’s
recommended pressure).
WARNING! Maximum tire pressure under any
circumstances is 30 p.s.i. Equal tire pressure should
be maintained on both tires.
Gas & Oil Fill-Up
Service the engine with gasoline and oil as instructed in the
separate engine manual packed with your tiller. Read the
instructions carefully.
WARNING! Use extreme care when handling
gasoline. Gasoline is extremely flammable and the
vapors are explosive. Never fuel the machine
indoors or while the engine is hot or running.
