PARTS ORDERING/SERVICE ....................Rear Cover

This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forest covered, brush covered, or grass covered land unless the engine's exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it should be maintained in effective working order by the operator.

In the state of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on

federal lands. A spark arrester mufer is available at your

WARNING: Always stop engine and

disconnect spark plug wire before cleaning, lubricating or before performing any repairs or maintenance.

• Check oil level before each use and every 8 hours.

• Maintain engine oil as instructed in the separate

engine manual.

• Service air cleaner every 25 hours under normal conditions. Clean every few hours under extremely dusty conditions. Poor engine performance and

ooding usually indicates that the air cleaner should

be serviced. To service the air cleaner, refer to the separate engine manual.

• Spark plug replacement is recommended every 100 hours or yearly. Check the engine manual for correct

plug type and gap specications.

SERVICE AND ADJUSTMENTS

WARNING: Shut off (disengage) the Tine

Clutch Lever, the Tiller Engine and the Tractor Engine before making any repairs.

TINE CARE

• For best results — Tine Blades should be kept

reasonably sharp. The Tine Blade can be sharpened on a grinding wheel. Do not attempt to sharpen Tines while they are mounted to Tiller.

SPARE TINE DRIVE BOLTS

• The Tiller drive components are protected from

damage by (shearable) Grade 5 hex bolts in the Tine Assemblies. The hex bolts drive the tines and hold them in the proper location. Should the Tine

Assemblies strike or pick up a large hidden object or become jammed, the hex bolts will break and the

drive components will not be damaged.

• Two extra tine hex bolts and nuts are included with

the tiller. They are located in the Tiller Stake Support Bracket on the rear of the Tiller.

• The tine hex bolts are designed to be loose t. Do not

attempt to use a bolt or pin that is larger or harder than the original Grade 5 hex bolts.

STORAGE

Immediately prepare your tiller for storage at the end of the season or if the unit will not be used for 30 days or more.

CAUTION: Never store the tiller with gasoline in the tank inside a building, where

fumes may reach an open ame or spark.

Allow the engine to cool before storing in any enclosure.

ENGiNE

• Follow the instructions in the "Service & Storage"

section of the Engine Manual.

TiLLER

• Clean entire tiller (See "CLEANING" in the Customer

Responsibilities section of the manual).

• Inspect and replace belts, if necessary (See

belt replacement instructions in the Service and

Adjustments section of this manual.

• Lubricate as instructed in the Customer

Responsibilities section of this manual.

• Be sure that all nuts, bolts and screws are securely

fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary.

• Touch up all rusted or chipped paint surfaces; sand

lightly before painting.

• If possible, store tiller indoors and cover it to protect

from dust and dirt.

• Cover tiller with a suitable protective cover that does

not retain moisture. Do not use plastic. Plastic cannot breathe, which allows condensation to form and will cause your unit to rust.

WARNING: Never cover Tiller while engine and exhaust areas are still warm.
