To help you properly care for your engine, the following pages include a maintenance schedule, routine inspection procedures, and simple maintenance procedures using basic hand tools. Other service tasks that are more difficult, or require special tools, are best handled by professionals and are normally performed by a technician or other qualified mechanic.
Maintenance, replacement or repair of the emissions control devices and systems may be performed by any non-road engine repair establishment or individuals. However, items must be serviced by a service center to obtain “no charge” emissions control warranty service.

The maintenance schedule applies to normal operating conditions. If you operate your tiller under unusual conditions, such as sustained high-load or high-temperature operation, or use in unusually wet or dusty conditions, consult your servicing dealer for recommendations applicable to your individual needs and use.

SERVICING THE ROTOTILLER
The following information will help you make the necessary checks and perform the procedures required to follow the normal care recommendations made for your unit. If you prefer, your local authorized dealer can make these checks and perform the required procedures for you.

BELT MAINTENANCE

Check Belt Tension as follows:
Belt tension may decrease over time. It may need to be adjusted within the first half hour of operation, and should be checked after every ten hours of operation. Proper adjustment will assure long belt life. Too much or too little belt tension will cause premature belt failure.
An indication that the belt may need to be adjusted can be heard as a continuous squealing sound when the engagement lever is compressed, or the belt slips and tines won’t turn (see page 19).
NOTE: A short buzzing noise can be heard when engagement lever is released. This is normal, caused by the teeth of the cog belt catching the wire guide, stopping the rotation of the belt. This does not require the belt tension to be adjusted.

To check and adjust the forward belt tension:

Turn off engine. Engine must be cool.
Remove spark plug wire from spark plug and secure.
Remove pulley box cover by removing four cover bolts. SEE FIGURE 16.
With drive safety control lever in the neutral position, measure length of spring when in its relaxed state.
Pull down on drive safety control lever and measure length of spring when extended. Ideal length is 1/8″ – 1/4″ longer. SEE FIGURE 17.
Replace pulley box cover.

Change Drive Belt as follows:

Turn off engine. Engine must be cool.
Remove spark plug wire from spark plug and secure.
Remove pulley box cover by removing four bolts. SEE FIGURE 16.
Remove the belt from the engine pulley as follows:
a. Gently pull the engine recoil rope to rotate the pulley.
b. With the pulley turning, force the belt out of the groove and slide the belt free of the engine pulley.
c. Pull the belt down and out of the way.
d. Push the belt down and away from the transmission pulley to remove.
Install new belt as follows:
a. Place belt in transmission pulley groove.
b. Gently pull the engine recoil rope to rotate the pulley while forcing the belt into the engine pulley groove.
Recheck belt tension and adjust if necessary
Replace pulley box cover.
Attach spark plug wire.

WARNING

**** TO PREVENT ACCIDENTAL STARTING:

ENGINE MUST BE TURNED OFF AND COOL, AND SPARK PLUG CAP/WIRE MUST BE REMOVED AND SECURED FROM SPARK PLUG BEFORE CHECKING
AND ADJUSTING ENGINE OR EQUIPMENT.

**** PRACTICE SAFETY AT ALL TIMES. ENGINE MUST BE TURNED OFF AND ALLOWED TO COOL, AND SPARK PLUG WIRE MUST BE DISCONNECTED AND SECURED BEFORE ATTEMPTING ANY MAINTENANCE OR REPAIR.

DANGER
DO NOT STORE TILLER IN AN UNVENTILATED AREA WHERE FUEL FUMES MAY REACH FLAME, SPARKS, PILOT LIGHTS, OR AN IGNITED OBJECT. DRAIN FUEL OUTDOORS AWAY FROM ANY IGNITION SOURCES. USE ONLY APPROVED FUEL CONTAINERS.
ENGINE AND SURROUNDING PARTS BECOME EXTREMELY HOT DURING NORMAL OPERATION.
TEMPERATURE OF MUFFLER AND NEARBY AREAS MAY EXCEED 150°F (66°C). AVOID THESE AREAS. ALLOW ENGINE TO COOL COMPLETELY BEFORE TOUCHING THESE HOT SURFACES. THESE AREAS WILL CAUSE SERIOUS BURN INJURIES IF TOUCHED BEFORE THE ENGINE HAS COOLED.
ALWAYS KEEP HANDS AND FEET CLEAR OF ROTATING MACHINE PARTS.

NOTICE
CHECK FORWARD BELT TENSION REGULARLY. TOO MUCH OR TOOL LITTLE TENSION WILL CAUSE PREMATURE BELT FAILURE.
DO NOT USE CHOKE CONTROL TO STOP ENGINE. BACKFIRE OR ENGINE DAMAGE MAY OCCUR!
TO STOP THE ENGINE AT ANY TIME, MOVE THROTTLE CONTROL TO THE OF OR STOP POSITION, OR SET THE ON/ OFF SWITCH TO OFF.
NEVER RUN ENGINE WITHOUT COMPLETE AIR CLEANER INSTALLED ON ENGINE. ENGINE CAN OVERHEAT AND BECOME DAMAGED IF DEBRIS BLOCKS THE COOLING SYSTEM OR ROTATING SCREEN.

ENGINE MAINTENANCE

Refer to the engine manual included in your parts packet for information on engine maintenance. Your engine manual provides information and a maintenance schedule for performing the following tasks:

Check oil level before each use or after every 8 hours of operation.
Change oil after first 5-8 hours of operation. Change oil while engine is warm. Refill with new oil of recommended grade.
Check spark plug seasonally or every 100 hours of operation.
Service air cleaner.
Keep engine and parts clean.
Check engine and equipment often for loose nuts and bolts, keep these items tightened.

CHECK OR FILL ENGINE CRANKCASE

To change the oil, first remove the left side shield from the tiller. Then lock drag stake into deepest position and gently tip tiller to the left, resting it in a tilted position on its left outer tine, wheel, and drag stake. Remove oil fill plug with the tiller resting in the tilted position until all of the oil has been drained into an appropriate receptacle. SEE FIGURE 18. Wipe up any spilled oil residue and dispose of oil properly according to local laws and/or ordinances.
Return tiller back to its upright level position and add oil according to engine manual. Do not overfill. Use a clean, high quality detergent oil. Use no special additives with recommended oils. Do not mix oil with gasoline. Oil level must be full. Check the oil level by removing oil fill plug. Oil level should be up to the bottom of the fill plug opening on most engines.
Always check oil level before starting engine. Refer to engine manual for capacity and type of oil to use.

CLEAN TINE AXLE SHAFT

Turn off engine. Engine must be cool.
Remove spark plug wire and secure from spark plug.
Remove all vegetation, string, wire, and other material that may have accumulated on the axle between the inside set of tines and the seal on the transmission housing.
Replace spark plug wire.

LUBRICATION

Proper lubrication of moving mechanical parts is critical for proper care and maintenance. Oil the moving parts using a 30 weight oil.
STORAGE

PREPARE FOR STORAGE
Follow the steps below to prepare your tiller for storage. Read your engine manual for detailed instructions on preparing the engine for storage.

Protect tines and tine shafts from rust: – Coat the tine shaft lightly with axle grease.
Drain fuel system completely following engine manufacturer’s instructions or add fuel stabilizer to prevent fuel from gumming up during extended storage period.
While engine is still warm, drain the oil from the engine. Refill with fresh oil of the recommended grade.
Clean external surfaces, engine and cooling fan.
Remove spark plug, pour one ounce of SAE 30 oil into spark plug hole.
Plug hole and pull starter cord slowly to distribute oil evenly in cylinder head area.
Reinstall spark plug.
Transport unit to a suitable storage location. If you have chosen to use a fuel stabilizer and have not drained the fuel system, follow all safety instructions and storage precautions in this manual to prevent the possibility of fire from the ignition of gasoline fumes. Remember, gasoline fumes can travel to distant sources of ignition and ignite, causing risk of explosion and fire.
If there is any possibility of unauthorized use or tampering, remove the spark plug and store it in a safe place before storing the unit. Be sure to plug the spark plug hole to prevent foreign material from entering.
