Troy-Bilt 682J, E686N, E682L manual Tine Shaft Maintenance, Tire and Wheel Maintenance

Section 5: Maintenance

WARNING

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key, if so equipped.

Failure to follow these instructions can result in serious personal injury or property damage.

Tine Shaft Maintenance

After every 10 operating hours, remove the left- and right-side Bolo Tine holders and clear away dirt and debris that have accumulated on the tine shaft or inside the tine holders. Please follow this main- tenance recommendation, as debris can cause premature wear to the tine shaft and its oil seals. Refer to the previous tine holder removal instructions. After cleaning away any debris and removing old grease from the tine shaft, apply fresh grease to the tine shaft.

Tire and Wheel Maintenance

Check tire air pressure every 30 operating hours. The recommended pressure for tilling is 10-to-20 psi (pounds per square inch). Both tires should be inflated equally. (Unequal pressure can cause the tiller to pull to one side.)

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 5-39 or Figure 5-40.

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 build-up.

•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.

SLOW or FAST position to prevent the

wheels from turning.

3. Use a 5/16" drift pin (or a blunt point

16-penny nail) to drive the roll pin free.

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 (-) cable first followed by the positive (+) cable. Re- verse this procedure when reinstalling the battery.

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.

Ignition System Maintenance

Your engine is equipped with electronic ignition. It does not have a condenser or points, so there is no need to perform any regular tune-up maintenance on this system other than adjusting or replacing the spark plug.
