IMPORTANT: Do not spray engine with water to clean because water could contaminate fuel. Using a garden hose or pressure washing equipment can also force water into the air cleaner or muffler opening. Water in the air cleaner will soak the paper element, and water that passes through the element or muffler can enter the cylinder, causing damage.

WARNING

Accumulation of debris around muffler could cause a fire. Inspect and clean before every use.

Storage

CAUTION

Failure to use a fuel stabilizing additive or completely run the engine until it's out of fuel before off-season storage may result in damage to your engine's carburetor.

Subsequent damage would not be covered under the manufacturer's warranty.

Fuel that will be stored longer than 30 days needs to be pre-treated upon purchase with fuel stabilizer to prevent gum and varnish from forming in the engines fuel and intake system. Improper fuel storage can result in hard starting, no starting, stalling and poor performance. If the fuel in your engine deteriorates during storage, you may need to have the carburetor, and other fuel system components, serviced or replaced.

1. Remove all fuel from fuel tank by running engine until it stops from lack of fuel.

WARNING

Never leave engine unattended while running.

1. Change oil. See Oil Change on page 10.
2. Remove spark plug and pour about 1/2 an ounce of engine oil into cylinder. Replace spark plug and crank slowly to distribute oil.
3. Clean debris from around engine, under finger guard, and under, around and behind muffler. Touch up any damaged paint, and coat other areas that may rust with a light film of oil.
4. Store in a clean, dry and well ventilated area away from any appliance that operates with a flame or pilot light, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark producing electric motor, or where power tools are operated.
5. If possible, also avoid storage areas with high humidity, because that promotes rust and corrosion.
6. Keep the engine level in storage. Tilting can cause fuel or oil leakage.

Removing From Storage

1. Check your engine as described in Pre-Operation Check on page 8.
2. If the fuel was drained during storage preparation, fill the fuel tank with fresh fuel. If you keep a container of gasoline for refueling, make certain it contains only fresh fuel. Gasoline oxidizes and deteriorates over time, causing hard starting.
3. If the cylinder was coated with oil during storage preparation, the engine will smoke briefly at startup. This is normal.

THE EZ START PROMISE

PROVISIONS OF YOUR LIMITED WARRANTY

In addition to the other terms and conditions of the Limited Warranty applicable to your new mower, MTD LLC ("MTD") hereby warrants that your mower's engine will start on the first or second attempt by an able-bodied adult (subject to the limitations described below) for the duration of the manufacturer's limited warranty applicable to your product. If the engine on your mower fails to conform to this limited warranty, MTD will cover the cost of parts and labor associated with any adjustments and/or repairs necessary to return your engine to its warranted condition. In order to make a claim under these provisions of your warranty, you must bring the product and proof of purchase to an authorized MTD service provider. In many cases, the retailer who sold you your mower is not equipped to provide warranty service, so please locate the authorized service dealer nearest you by either calling the phone number provided in your Operators Manual or looking up an authorized service dealer on-line at www.mtdproducts.com.

ITEMS AND CONDITIONS NOT COVERED

The EZ Start Promise does not cover and/or apply to the following:

• Cost of regular maintenance service or parts, such as filters, fuel, lubricants, oil changes, spark plugs, air filter, blade sharpening, worn blades, cable/linkage adjustments, or brake and clutch adjustments
• Transportation costs to and from an authorized MTD service provider
• Any engine used for commercial, rental, institutional, governmental, or non-residential applications
  Any product or part that has been altered or misused or required replacement or repair due to misuse, accidents, or lack of proper maintenance
• Repairs necessary due to improper battery care, electrical supply irregularities, or failure to properly prepare the mower prior to any period of non-use over three months
• Pickup and/or delivery charges

• Operational misuse, neglect, accidents, unauthorized repairs or attempted repairs of the engine or its components by anyone other than an authorized MTD service provider.

• Repairs or adjustments to correct starting difficulties due to any of the following: failure to follow proper maintenance procedures — rotary mower blade striking an object — contaminants in the fuel system — improper fuel or fuel/ oil mixture (consult your Operator's Manual if in doubt) — failure to drain the fuel system prior to any period of non-use over three months.

• Any starting problem which results from the use of inappropriate fuels, lubricants, or additives.
• Special conditions or circumstances that normally require more than two pulls to start, specifically: 1) First start-up following your initial purchase, 2) first time starts after extended period(s) of non-use over one month or seasonal storage, 3) cool temperature starts such as those found in early spring and late autumn, and 4) difficult starting that results from the operator's failure to follow the proper starting procedures identified in the Operator's Manual. If you are having difficulty starting your unit, please check the Operator's Manual to ensure that you are using the correct starting procedures. This can save an unnecessary visit to a Service Dealer.

OWNER RESPONSIBILITIES

You must maintain your mower (including its engine) by following the maintenance procedures and starting instructions described in the Operator's Manual. Such routine maintenance, whether performed by a dealer or by you, is at your expense. In addition, please retain your proof of purchase and service receipts as these may be required to validate a claim.

GENERAL CONDITIONS

An authorized MTD service provider using approved replacement parts must perform all repairs covered by the EZ Start Promise. Repair by an MTD authorized service dealer is your sole remedy under this warranty. MTD is not liable for indirect, incidental, or consequential damages in connection with the use of the products covered by these warranties, including any cost or expense of providing substitute equipment or service during reasonable periods of malfunction or non-use pending completion of repairs under this warranty.

Some states do not allow exclusions of incidental or consequential damages, or limitations on how long an implied warranty lasts, so certain exclusions and limitations may not apply to you.
