ENGINE SAFETY PRECAUTIONS

Warning Carbon Monoxide Poisoning Engines give off carbon monoxide, an odorless, colorless,

poisonous gas. Carbon monoxide may be present even if you do not smell or see any engine exhaust. Breathing carbon monoxide can cause nausea, fainting or death, in addition to drowsiness, dizziness and confusion. If you experience any of these symptoms, seek fresh air and medical attention immediately.

If your product comes with a separate engine manual, be sure to read and follow all safety and warning precautions outlined there, in addition to any in this manual.

Preventing Carbon Monoxide Poisoning

• Always start and run engine outdoors. Do not start or run engine in an enclosed area, even if doors or windows are open.

• Never try to ventilate engine exhaust indoors. Carbon monoxide can reach dangerous levels very quickly.

• Never run engine outdoors where exhaust fumes may be pulled into a building.

• Never run engine outdoors in a poorly ventilated area where the exhaust fumes may be trapped and not easily taken away. (Examples include: in a large hole or areas where hills surround your working area.)

• Never run engine in an enclosed or partially enclosed area. (Examples include: buildings that are enclosed on one or more sides, under tents, car ports or basements.)

• Always run the engine with the exhaust and muffler pointed in the direction away from the operator.

• Never point the exhaust muffler towards anyone. People should always be many feet away from the operation of the engine and its attachments.

• Do not change the engine governor settings or over-speed the engine.

Gasoline Fires and Handling Fuel Safely

Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.

• When storing extra fuel be sure that it is in an appropriate container and away from any fire hazards.

• Prevent fire and explosion caused by static electric discharge. Use only nonmetal, portable fuel containers approved by the Underwriter’s Laboratory (U.L.) or the American Society for Testing & Materials (ASTM).

• Always fill fuel tank outside in a well ventilated area. Never fill your fuel tank with fuel indoors. (Examples include: basement, garage, barn, shed, house, porch, etc.) Never fill tank near appliances with pilot lights, heaters, or other ignition sources. If the fuel has to be drained, this should

MAINTENANCE AND STORAGE

STEPS FOR WORKING ON EQUIPMENT

1. Flip the ON/OFF switch to the OFF position.

2. Replace or repair the part on the MC440.

3. Check all parts that were repaired, or removed during repair, that they are secure and fit correctly.

NOTE: All repair parts must come from the factory. Never replace parts that are not specifically designed for the cultivator.

MC440 MAINTENANCE

1. The transmission case has grease installed at the factory. It is recommended that once a year the gear case be split by a qualified service professional and the grease level checked. Add a molylithium type grease only if level of grease is below top of the gears. DO NOT OVERFILL.

2. Keep all screws, nuts, and bolts tight.

3. For cold weather operation, store the unit in a cool environment. Transferring the unit from a cold to a warm place can cause the build up of harmful condensation.

CAUTION

PRACTICE SAFETY AT ALL TIMES. ENGINE MUST BE TURNED OFF AND ALLOWED TO COOL BEFORE ATTEMPTING ANY MAINTENANCE OR REPAIR.

TO PREVENT ACCIDENTAL STARTING: ENGINE MUST BE TURNED OFF AND COOL BEFORE

CHECKING AND ADJUSTING ENGINE OR EQUIPMENT. TEMPERATURE OF MUFFLER AND NEARBY AREAS

MAY EXCEED 150° F 65° C. AVOID THESE AREAS. CHECK CULTIVATOR OFTEN FOR LOOSE NUTS AND

BOLTS. KEEP THESE ITEMS TIGHTENED. NEVER STORE ENGINE WITH FUEL IN THE TANK INSIDE

A BUILDING. POTENTIAL SPARKS MAY BE PRESENT FOR IGNITION OF FUEL AND FUEL VAPORS.

AN ADULT ONLY MUST DO MAINTENANCE AND REPAIR ON ENGINE AND CULTIVATOR.

ENGINE MUST BE TURNED OFF AND COOL BEFORE ANY REPAIR OR MAINTENANCE CAN BE DONE.

ENGINE MAINTENANCE

Please read the maintenance schedule and observe these recommendations to extend the life of your engine.

Good maintenance is essential for safe, economical, and troublefree operation. It will also help reduce air pollution. 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 an authorized dealer to obtain “no charge” emissions control warranty service.

The maintenance schedule applies to normal operating conditions. If you operate your engine 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.

Check for parts online at www.getearthquake.com or call 800-345-6007 M-F 8-5 13

LUBRICATION

Choose engine oil that meets or surpasses the latest API service classification. For temperatures higher than 32º F, use 10W-30 motor oil. Use SAE 5W-30 if temperatures are below 32º F.

OIL MAINTENANCE

After the first five hours of operating a new Viper engine the oil should be replaced, and every 50 hours of operating time thereafter. The oil should be changed every 25 hours if used under severe conditions, such as in high temperatures or under heavy loads. Check oil periodically; do not overfill!

CHANGING OIL

Be sure the engine is not operating and is located on a level surface before checking or refilling oil. Engine should be warm for easy removal of oil.

IMPORTANT

PROPER POSITION FOR CHECKING OIL LEVEL OR REFILLING OIL IS FACE DOWN, WITH THE GAS TANK OF THE MC440 DOWN ON A HORIZONTAL SURFACE. SEE FIGURE 3A ON PAGE 10. FAILURE TO MAINTAIN THIS POSITION CAN RESULT IN OVER FILLING THE ENGINE WITH OIL WHICH WILL IMPAIR THE ENGINE’S PERFORMANCE.

STEPS FOR CHANGING OIL

1. Flip the ON/OFF switch to the OFF position.

2. Unscrew oil drain screw and empty oil into suitable oil container. (SEE FIGURE 3A on PAGE 10) Dispose of oil properly.

3. Reinsert drain screw and remove oil dipstick.

4. Fill with appropriate oil to “FULL“ or top line of dipstick (SEE FIGURE 3B on page 10).

5. Reinsert dipstick or oil fill cap and tighten.

Operator's Manual

MC440 4-Cycle Cultivator

CAUTION

TO AVOID INJURY OR DEATH, NEVER SIPHON FUEL BY MOUTH.

NEVER STORE CULTIVATOR WITH FUEL IN THE FUEL TANK INSIDE AN ENCLOSED AREA OR BUILDING.

COOLING FINS

Cooling fins, air inlets and linkages must be free from any debris before each use.

AIR FILTER

Never run engine without air cleaner properly installed. Added wear and engine failure may occur if air cleaner is not installed on engine.

Service air cleaner every 3 months or after 20 hours of operation. Clean filter daily in extremely dusty conditions.

Steps for Replacing and Cleaning Air Filter (Block Style Foam Filter)

1. Before removing the air filter cover, move the choke lever to the CHOKE position.

2. To remove air filter cover, unscrew the cover bolt with a screw driver and gently pop out the front latch tab. The cover then can be slid off the back latch tabs and away from the engine.

SEE FIGURE 9

3. Remove the foam filter and fiber filter elements. Replace with a new fiber filter and a new oiled foam filter (SEE FIGURE 10), or clean the original foam and fiber filters with warm water and mild soap. Remember to thoroughly oil the foam filter with 30 or 40 weight motor oil and squeeze out any excess oil before reinstalling it. Make sure to press the foam filter evenly into place over the fiber filter to ensure that the foam is fully seated into its sealed position.

4. Replace the air filter cover by first connecting the back latch tabs then swinging the cover, making sure the foam filter block stays fully seated and in its proper position, and connect the front latch tab so that it is secured into place.

5. Screw the cover bolt back into place. Check that the cover is securely attached by pulling slightly on the cover. If the cover doesn’t move when pulled, it is secure.

IMPORTANT

NEVER TWIST AIR FILTERS WHEN CLEANING. ALWAYS PRESS.

MC440 4-Cycle Cultivator

TRANSPORTING YOUR MC440

1. After using the cultivator, and before transporting it in a truck bed, check that the gas cap is screwed on (clockwise) tightly. The gas cap will not leak during transporting if gas cap is tight. Never transport engine inside an enclosed space within a vehicle. Fuel or fuel vapors may ignite causing serious injury or death.

2. If fuel is present in the fuel tank, transport in an open vehicle in an upright position.

3. If an enclosed vehicle must be used, remove gas into an approved red fuel container. DO NOT siphon by mouth.

4. Wipe away any spilled fuel from engine and cultivator. Allow to dry.

5. Run engine to use up the fuel in the carburetor and fuel tank. Always run engine in a well ventilated area.

6. Gas cap should be screwed down tightly before transporting your MC440 in a vehicle.

LONGTERM STORAGE

If your MC440 will not be used for more than one month, prepare it for long-term storage.

Steps for Long-Term Storage

1. Mix an appropriate amount of fuel stabilizer, such as STABIL®, to fresh gasoline, in the ratio recommended on the stabilizer packaging. Run the engine for five minutes to distribute the stabilizer mixture throughout the fuel system. This will prevent gum, varnish and corrosion build up in your fuel system during long-term storage for up to 12 months.

2. Store 4-cycle cultivator engine in a vertical position.

3. Remove all debris from cultivator tines and engine.

FEDERAL EMISSION CONTROL WARRANTY STATEMENT

Operator's Manual

MC440 4-Cycle Cultivator

YOUR WARRANTY RIGHTS AND OBLIGATIONS

The United States Environmental Protection Agency (EPA), together with Ardisam, Inc. (Ardisam), are pleased to explain the Emission Control System Warranty on your small off-road engine (SORE). New small off-road engines must be designed, built and equipped to meet stringent anti-smog standards the federal government. Ardisam will warrant the emission control system on your engine for the periods of time listed below provided there has been no abuse, neglect, modification or improper maintenance of your engine.

The emission control system includes all components whose failure would increase the emissions of any regulated pollutant. These components are listed in the emission-related parts list located in a subsequent section of this emissions warranty statement. Ardisam will repair your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur.

MANUFACTURER’S WARRANTY COVERAGE:

The emission control system is warranted for two years. If, during such warranty period, any emission-related part on your engine is found to be defective in materials or workmanship, repairs or replacement will be performed by a Ardisam Authorized Warranty Service Facility.

PURCHASER’S/OWNER’S WARRANTY RESPONSIBILITIES:

As the SORE purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory supplied Manual(s). For warranty purposes, Ardisam recommends that you retain all receipts covering maintenance on your SORE. However, Ardisam cannot deny warranty solely because of the lack of receipts or for your failure to ensure the completion of all scheduled maintenance.

As the SORE purchaser/owner, you should, however, be aware that Ardisam may deny any and/or all warranty coverage or responsibility if your SORE or a part/component thereof, has failed due to abuse, neglect, improper maintenance or modifications, or the use of counterfeit and/or “grey market” parts not made, supplied or approved by Ardisam.

You are responsible for presenting your SORE to an Ardisam Authorized Warranty Service Facility as soon as a problem occurs. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.

Warranty service can be arranged by contacting either your selling dealer or a Ardisam Authorized Warranty Service Facility. To locate the Ardisam Authorized Warranty Service Facility nearest you, call our free number:

800-345-6007

IMPORTANT NOTE: This warranty statement explains your rights

and obligations under the Emission Control System Warranty (ECS Warranty), which is provided to you by Ardisam pursuant to federal law. See also the Ardisam “Product Warranty” (non-emission warranties), which is enclosed herewith on a separate sheet or located in additional materials accompanying this product. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in terms between the ECS Warranty

and the Ardisam Warranty, the ECS Warranty shall apply except in circumstances where the Ardisam Warranty may provide a longer warranty period. Both the ECS Warranty and the Ardisam Warranty describe important rights and obligations with respect to your new engine.

Warranty service can be performed only by an Ardisam Authorized Warranty Service Facility. When requesting warranty service, evidence must be presented showing the date of the sale to the original purchaser/owner. Ardisam will not be responsible for any and/or all damages or losses incurred while the engine is being transported/ shipped for inspection or warranty repairs.
