Tire and Wheel Maintenance
Check tire air pressure every 30 operating hours. The recommended pressure for tilling is 10 psi to 20 psi. Both tires should be inflated equally. (Unequal pressure can cause the tiller to pull to one side.)
Wheel Shaft Maintenance
After every 10 operating hours, remove the wheels and clear away dirt and debris that has accumulated on the wheel shaft Please follow this maintenance recommendation, as debris can cause premature wear to the wheel shaft and its oil seals.
1.Prop the transmission up with a sturdy block to raise the wheels off the ground.
2.Remove the wheels by removing the hex bolt and lock nut which secures each to the wheel shaft.
WARNING
Wear safety goggles when driving the roll pin into or from the wheel hub to protect your eyes from the possibility of flying metal particles.
After cleaning away any debris and removing old grease, apply fresh grease to the wheel shaft before
the engine when it is low on oil will quickly ruin the engine.
It is recommended that you change the oil every ten (10) operating hours and even sooner when operating in extremely dirty or dusty conditions. Refer to the separate Engine Owner’s Manual for detailed service instructions.
Air Cleaner Maintenance
The engine is equipped with a dual element air cleaner that filters the air twice before it enters the carburetor to mix with the fuel.
The engine air cleaner filters dirt and dust out of the air before it enters the carburetor. Operating the engine with a dirty, clogged air filter can cause poor performance and damage to the engine. Never operate the engine without the air cleaner installed. Inspect and service the air cleaner more often if operating in very dusty or dirty conditions.
It is critical that the filters be kept clean and properly installed at all times. See the location of the air cleaner assembly on your engine by referring to Figure
Refer to the engine manufacturer’s litera- ture supplied with your tiller for complete air cleaner service and maintenance infor- mation.
Throttle Cable Maintenance
The throttle lever settings are factory- adjusted, so unnecessary adjustments should not be made. However, if the engine does not start or stop, or respond immediately to various throttle lever settings, then adjustments may be necessary. Please refer to the engine manufacturer literature supplied with your tiller for specific adjustment instructions.
system other than adjusting or replacing the spark plug.
Spark Plug Maintenance
The spark plug must be in good condition for proper engine operation. Remove and inspect the plug every 50 operating hours or annually, whichever occurs first.
The correct electrode gap is .030". Check the gap with a feeler gauge. Do not use a spark plug if the porcelain is cracked, the electrodes are pitted or burned, or if other visible damage is present.
NOTE: Do not wire brush or sandblast the spark plug to clean it – loose particles can enter the engine, causing damage!
To replace the plug, first tighten it securely by hand, then use a spark plug wrench to tighten the plug an extra 1/4 turn.
Battery Care and Maintenance
The battery is sealed and is maintenence- free. Acid levels cannot be checked.
•Always keep the battery cables and terminals clean and free of corrosive
•After cleaning the battery and terminals, apply a light coat of petroleum jelly or grease to the terminals and cover both terminals with the rubber boots.
WARNING
When removing the battery, always disconnect the negative
wheels.
