OPERATION
BEFORE STARTING ENGINE
ADD OIL
Your lawnmower is shipped without oil in the engine. For type and grade of oil to use, see “ENGINE” in the Maintenance section of this manual.
CAUTION: DO NOT overfill engine with oil, or it will smoke heavily from the muffler on startup.
1.Be sure lawnmower is level.
2.Remove dipstick from oil fill spout (Figure 15).
3.You receive a container of oil with the unit. Slowly pour the entire container down the oil fill spout into the engine.
NOTE: Initial oil fill requires only 18 oz. due to residual oil in engine from the manufacturers 100% quality testing. When changing oil you may need 20 oz.
4. Insert and tighten dipstick.
IMPORTANT: Check oil level before each use. Add oil if needed. Fill to full line on dipstick.
IMPORTANT: Change the oil after every 25 hours of operation or each season. You may need to change the oil more often under dusty, dirty conditions. See “TO CHANGE ENGINE OIL” in the Maintenance section of this manual.

ADD GASOLINE
IMPORTANT: Fill fuel tank to bottom of tank filler neck. Do not overfill. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness (Figure 15).
CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.
Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Empty the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

MOWING TIPS
CAUTION: Do not use de-thatcher blade attachments on your mower. Such attachments arehazardous,willdamageyourmowerandcould void your warranty.
•Under certain conditions, such as very tall grass, it may be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of grass clippings. It may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time.
•For extremely heavy cutting, reduce the width of cut by overlapping previously cut path and mow slowly.
•For better grass bagging and most cutting conditions, the engine speed should be set in the FAST position.
•When using a rear discharge lawn mower in moist, heavy grass, clumps of cut grass may not enter the grass catcher. Reduce ground speed (pushing speed) and/or run the lawn mower over the area a second time.
•If a trail of clippings is left on the right side of a rear discharge mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass.
•Pores in cloth grass catchers can become filled with dirt and dust with use and catchers will collect less grass. To prevent this, regularly hose catcher off with water and let dry before using.
•Keep top of engine around starter clear and clean of grass clippings and chaff. This will help engine air flow and extend engine life.

OPERATION
MULCHING MOWING TIPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE “CLEANING”INTHEMAINTENANCESECTIONOFTHISMANUAL.
•The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients for the lawn. Always mulch with your highest engine (blade) speed as this will provide the best recutting action of the blades.
•Avoid cutting your lawn when it is wet. Wet grass tends to form clumps and interferes with the mulching action. The best time to mow your lawn is the early afternoon. At this time the grass has dried, yet the newly cut area will not be exposed to direct sunlight.
•For best results, adjust the lawn mower cutting height so that the lawn mower cuts off only the top one-third of the grass blades (Figure 19). If the lawn is overgrown it will be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of mulched grass. For extremely heavy mulching, reduce your width of cut by overlapping previously cut path and mow slowly.
MAX 1/3
Figure 19
•Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings. When doing a second cut, mow across (perpendicular) to the first cut path.
•Change your cutting pattern from week to week. Mow north to south one week then east to west the next week. This will help prevent matting and graining of the lawn.

GENERAL RECOMMENDATIONS
The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain mower as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your unit. At least once a season, check to see if you should make any of the adjustments described in the Service and Adjustments section of this manual.
•At least once a year, replace the spark plug, clean or replace air filter element and check blade for wear. A new spark plug and clean/new air filter element assure proper air-fuel mixture and help your engine run better and last longer.
•Follow the maintenance schedule in this manual.
BEFORE EACH USE
1.Check engine oil level.
2.Check for loose fasteners.
LUBRICATION
Keep unit well lubricated (See “LUBRICATION CHART”).
IMPORTANT: DO NOT OIL OR GREASE PLASTIC WHEEL BEARINGS. VISCOUS LUBRICANTS WILL ATTRACT DUST AND DIRT THAT WILL SHORTEN THE LIFE OF THE SELFLUBRICATING BEARINGS. IF YOU FEEL THEY MUST BE LUBRICATED, USE ONLY A DRY, POWDERED GRAPHITE

MAINTENANCE
TO SHARPEN BLADE
NOTE: We do not recommend sharpening blade - but if you do, be sure the blade is balanced. An unbalanced blade will cause eventual damage to lawn mower or engine.
•The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower.
•To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer, follow the instructions supplied with balancer.)
NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not.
1.Slide blade on to an unthreaded portion of the steel bolt or pin and hold the bolt or pin parallel with the ground. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced (Figure 21).

GRASS CATCHER
•The grass catcher may be hosed with water, but must be dry when used.
•Check your grass catcher often for damage or deterioration. Through normal use it will wear. If catcher needs replacing, replace only with approved replacement catcher. Give the lawn mower model number when ordering.
GEAR CASE
•To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season.
•The gear case is filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case.
ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service classification SG–SL. Select the oil's SAE viscosity grade according to your expected operating temperature (Figure 22).
NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, and you should check your engine oil level frequently to avoid possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at least once a year if the lawn mower is not used for 25 hours in one year.
Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.

MAINTENANCE
TO CHANGE ENGINE OIL
NOTE: Before tipping lawn mower to drain oil, empty fuel tank by running engine until fuel tank is empty.
1.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.
2.Remove engine oil cap/dipstick; lay aside on a clean surface.
3.Tip lawn mower on its side as shown and drain oil into a suitable container. Rock lawn mower back and forth to remove any oil trapped inside of engine (Figure 23).
4.Wipe off any spilled oil from lawn mower or side of engine.
5.Slowly pour oil down the oil fill spout, stopping every few ounces to check the oil level with the dipstick.
6.Stop adding oil when you reach the FULL mark on the dipstick. Wait a minute to allow oil to settle.
7.Continue adding small amounts of oil, rechecking the dipstick until oil level settles at FULL. DO NOT overfill, or engine will smoke heavily from the muffler on startup.
8.Always be sure to retighten oil dipstick before starting engine.
9.Reconnect spark plug wire to spark plug.

AIR FILTER
Your engine will not run properly using a dirty air filter. Replace paper cartridge every 100 hours of operation or every season, whichever occurs first. Service air cleaner more often under dusty conditions.
NOTE: The air cleaner system uses a pleated filter with an optional pre-cleaner. The pre-cleaner can be washed and reused.
1.Loosen the fastener that holds the cover. Remove the cover (Figure 24).
2.Remove the pre-cleaner and the filter.
3.To loosen debris, gently tap the filter on a hard surface. If the filter is excessively dirty, replace with a new filter.
4.Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air dry. Do not oil the precleaner.
CAUTION: Petroleumsolvents,suchaskerosene, are not to be used to clean cartridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge.
5.Assemble the dry pre-cleaner to the filter.
6.Install the filter and pre-cleaner into the base. Make sure filter fits securely in the base.
7.Install air filter cover and secure with fastener. Make sure the fastener is tight.
