Removing the Wheels
Each wheel is secured by a roll (spirol) pin that passes through the wheel hub and the wheel shaft. Drive the roll pin out to remove a wheel.
1. | Prop the transmission up with a sturdy |
block to raise the wheel you want to | |
remove off the ground. | |
2. | Move the Wheel Speed Lever to either |
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 carbure- tor. Operating the engine with a dirty, clogged air filter can cause poor perfor- mance 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.
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
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.
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.
WARNING
When removing the battery, always dis- connect the negative
Engine Oil Maintenance
Check the engine oil level before starting the engine each day and after each 5 hours of continuous operation. Running the engine when it is low on oil will quickly ruin the engine.
