3. If necessary to add oil because of some type of leakage, use a quality 20W50 motor oil and add only enough oil to bring the level to the "FULL COLD" line. Reinstall the cap and fully tighten. Note: Prior to the initial operation of the mower, the oil level in the reservoir may be slightly higher than the maximum due to air in the oil lines. Operation of the mower will eventually purge the air from the lines and the oil level will settle to the maximum. Mower Storage If your mower is not going to be operated for an extended period of time (30 days to approximately six months), the mower should be prepared for storage. Store the mower in a dry and protected location. If stored outside, cover the mower (including the tires) to protect it from the elements. The procedures outlined below should be performed whenever the mower is placed in storage. 1. Change the engine oil and filter following the instructions provided in the Engine Operator's Manual packed with this manual. WARNING Never store the mower with fuel in the tank indoors or in poorly ventilated enclosures, where fuel fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer, etc. 2. If storing the mower for 30 days or more: a. To prevent gum deposits from forming inside the engine's carburetor and causing possible malfunction of the engine, the fuel system must be either completely emptied, or the gasoline must be treated with a stabilizer to prevent deterioration. WARNING Fuel left in the fuel tank deteriorates and will cause serious starting problems. b. Use a fuel stabilizer for storage between 30 and 90 days: • Read the product manufacturer's instructions and recommendations. • Add to clean, fresh gasoline the correct amount of stabilizer for the capacity (approximately 3 gallons) of the fuel system. • Fill the fuel tank with treated fuel and run the engine for 2-3 minutes to get stabilized fuel into the carburetor. c. Emptying the fuel system for storage of more than 90 days: • Prior to putting the mower in storage, monitor fuel consumption with the goal of running the fuel tank empty. • Run the engine until it begins to stall. Use the choke to keep the engine running until all fuel in the carburetor has been exhausted. • Referring to the Engine Operator's Manual, drain the fuel from the carburetor bowl. 3. Clean the engine and the entire mower thoroughly. 4. Fully charge the battery, then disconnect the negative cable at the battery to prevent possible discharge. Recharge the battery periodically when in storage. Note: Remove the battery if exposed to prolonged periods of sub-freezing temperatures. Store in a cool, dry location where temperatures are above freezing. 5. Lubricate all lubrication points. Note: Using a pressure washer or garden hose is not recommended for cleaning your mower. It may cause damage to electrical components, spindles, pulleys, bearings or the engine. The use of water will result in shortened life and reduce serviceability. Removing The Mower From Storage 1. Check the engine oil. 2. Fully charge the battery and inflate the tires to the recommended pressure. 3. Fill the fuel tank with clean, fresh gasoline. 4. Start the engine and allow to idle for a few minutes to ensure engine is operating properly. 5. Drive the mower without a load to make certain all the mower systems are functioning properly. Adjustments WARNING Shut the engine off, remove the ignition key and engage the parking brake before making adjustments. Protect your hands by using heavy gloves when handling the blades. Deck Leveling WARNING Shut the engine off, remove the key and engage the parking brake before making adjustments. Protect your hands by using heavy gloves when handling the blades. Leveling the Deck Note: Check the mower's tire pressure before performing any deck leveling adjustments. Refer to Tires for information regarding tire pressure. Always level the deck side-to-side before front to rear. If the cutting deck appears to be mowing unevenly, a side-to-side adjustment can be performed. Adjust if necessary as follows: 1. Park the mower on a flat level surface. 2. Measure the distance from the outside of the left blade tip to the ground and the distance from the outside of the right blade tip to the ground. Both measurements taken should be equal. If they're not, proceed to the next step. 3. There are four adjustment points on the deck. Each of the deck lift adjustment pins has an adjustment bolt (a). See Figure 4-8. Raise or lower each side of the deck using the four bolts (a) until the side-to-side height is equal. (a) Figure 4-8 The front of the deck should be between 1⁄4-3⁄8" lower than the rear of the deck. Adjust if necessary as follows: 1. Raise or lower the front and/or rear of the deck using the four adjustment bolts (a) on the deck lift adjustment pins until the front of the deck is 1⁄4-3⁄8" lower than the rear of the deck. See Figure 4-8. Adjusting the Gauge Wheels (If Equipped) WARNING Keep hands and feet away from the discharge opening of the cutting deck. The front gauge wheels on the mower deck are an anti-scalp feature, and should not ride on the ground. The front gauge wheels should be approximately 1⁄4-1⁄2" above the ground when the deck is set in the desired height setting. Using the deck lift handle, set the deck in the desired height setting, then check the gauge wheel distance from the ground below. If necessary adjust the front gauge wheels as follows: 1. Visually check the distance between the front gauge wheels and the ground. If the gauge wheels are near or touching the ground, they should be raised. If more than 1⁄2" above the ground, they should be lowered. 2. Remove the lock nut (a) securing one of the front gauge wheel (b) to the deck. Remove the front gauge wheel (b), hex screw (c) and spacer (d). See Figure 4-9. (b) (a) (d) (e) (c) Figure 4-9 Section 4 - Product Care 15
