Set-Up

Gas and Oil Fill-Up

Refer to the separate engine owner’s manual for additional engine information.

1. Add the oil provided before starting the unit for the first time out of the box.
2. Service the engine with gasoline as instructed in the separate engine owner’s manual.

WARNING: Use extreme care when handling gasoline. Gasoline is extremely flammable, and the vapors are explosive. Never fuel the machine indoors or while the engine is hot or running. Extinguish cigarettes, cigars, pipes, and other sources of ignition.

Controls and Features

Blade Control

The blade control is attached to the upper handle of the mower. Depress and squeeze it against the upper handle to operate the unit. Release it to stop the engine and blade. WARNING: This blade control is a safety device. Never attempt to bypass its operations.

Cutting Height Adjustment Lever

One adjustment lever is located near the right rear wheel, and one is located near the right front wheel. Both levers have to be at the same relative position to ensure a uniform cut. To adjust the cutting height, refer to the “Assembly & Set-Up” Section.

Grass Catcher

The grass catcher, located at the rear of the mower, is used to bag the grass clippings for disposal at another site. Once the bag is full, lift it up through the handles using the strap provided and empty it before any further mowing.

Mulch Plug

The mulch plug is used for mulching purposes. Instead of collecting the grass clippings in a grass catcher or using the side discharge chute, some mower models have the option of recirculating the clippings back to the lawn. This is called mulching.

Side Discharge Chute

Your mower is shipped as a mulcher. To discharge the grass clippings to the side instead, follow the instructions in the “Assembly & Set-Up” section to attach the side discharge chute.

WARNING: Keep hands and feet away from the chute area on the cutting deck. Refer to the warning label on the unit.

Recoil Starter

The recoil starter is attached to the right upper handle. Stand behind the unit and pull the recoil starter rope to start the unit.

Operation

Starting Engine

WARNING: Be sure no one other than the operator is standing near the lawn mower while starting the engine or operating the mower. Never run the engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and deadly gas. Keep hands, feet, hair, and loose clothing away from any moving parts on the engine and lawn mower.

Follow the set of instructions pertaining to your unit. Refer to the engine manual for help with the engine.

Briggs & Stratton Engine:

1.  Standing behind the mower, squeeze the blade control against the upper handle. See Figure 5-1.
2. Holding these two handles together firmly, grasp the recoil starter handle and pull the rope out with a rapid, continuous, full arm stroke. See Figure 5-1. Keeping a firm grip on the starter handle, let the rope rewind slowly. Repeat until the engine cranks. Let the rope rewind slowly each time.

Honda Engine:

1. Place the fuel valve lever found on the left side of the engine into the ON (OPEN) position. See Figure 5-2.
2. Move the choke lever all the way backward into the choke position.
3. Standing behind the mower, squeeze the blade control against the upper handle. The choke will now begin to slowly return to the off choke position after activating the blade control. Therefore, quickly move on to step four below.
4. Holding these two handles together firmly, grasp the recoil starter handle and pull the rope out with a rapid, continuous, full arm stroke. See Figure 5-2. Keeping a firm grip on the starter handle, let the rope rewind slowly. Repeat until the engine cranks. Let the rope rewind slowly each time.

Stopping Engine

1. Release the blade control to stop the engine and blade.

WARNING: Wait for the blade to stop completely before performing any work on the mower or removing the grass catcher.

Using Your Lawn Mower

Be sure the lawn is clear of stones, sticks, wire, or other objects that could damage the lawn mower or engine. Such objects could be accidentally thrown by the mower in any direction and cause serious personal injury to the operator and others.

WARNING: The operation of any lawnmower can result in foreign objects being thrown into the eyes, which can damage your eyes severely. Always wear safety glasses while operating the mower or while performing any adjustments or repairs on it.

Using as Mulcher

For mulching grass, remove the grass catcher and allow the rear discharge door to close the rear opening of the mower. For effective mulching, do not cut wet grass. If the grass has been allowed to grow in excess of four inches, mulching is not recommended. Use the grass catcher to bag clippings instead.

Using Grass Catcher

You can use the grass catcher to collect clippings while you are operating the mower.

1. Attach the grass catcher following the instructions in the “Assembly & Set-Up” section. Grass clippings will automatically collect in the bag as you run the mower. Operate the mower till the grass bag is full.
2. Stop the engine completely by releasing the blade control. Make sure that the unit has come to a complete stop.
3. Lift the discharge door and pull the grass bag up and away from the mower to remove the bag. Dispose of the grass clippings and reinstall the bag when complete.

WARNING: If you strike a foreign object, stop the engine. Remove the wire from the spark plug, thoroughly inspect the mower for any damage, and repair damage before restarting and operating. Extensive vibration of the mower during operation is an indication of damage. The unit should be promptly inspected and repaired.

Maintenance & Adjustments

Maintenance

General Recommendations

• Always observe safety rules when performing any maintenance.
• 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, the operator must maintain the lawn mower as instructed here.
• Changing of engine-governed speed will void the engine warranty.
• All adjustments should be checked at least once each season.
• Periodically check all fasteners and make sure these are tight.

WARNING: Always stop the engine, disconnect the spark plug, and ground against engine before performing any type of maintenance on your machine.

Lubrication

1. Lubricate pivot points on the blade control at least once a season with light oil. The blade control must operate freely in both directions. See Figure 6-1.
2. Follow the accompanying engine manual for the lubrication schedule and instructions for engine lubrication.

Deck Care

Clean the underside of the mower deck after each use to prevent the buildup of grass clippings or other debris. Follow the steps below for this job.

1. Disconnect the spark plug wire. Drain gasoline from the lawn mower or place a piece of plastic under the gas cap.
2. Tip the mower so that it rests on the housing. Keep the side with the air cleaner facing up. Hold the mower firmly.WARNING: Never tip the mower more than 90° in any direction, and do not leave the mower tipped for any length of time. Oil can drain into the upper part of the engine, causing a starting problem.
3. Scrape and clean the underside of the deck with a suitable tool.
4. Put the mower back on its wheels on the ground. If you had put plastic under the gas cap earlier, make sure to remove it now.

Engine Care

A list of key engine maintenance jobs required for good performance by the mower is given below. Follow the accompanying engine manual for a detailed list and instructions.

• Maintain oil level as instructed in the engine manual.
• Service the air cleaner every 25 hours under normal conditions. Clean every few hours under extremely dusty conditions. Poor engine performance and flooding usually indicate that the air cleaner should be serviced. To service the air cleaner, refer to the engine manual.
• Clean the spark plug and reset the gap once a season. Spark plug replacement is recommended at the start of each mowing season. Check the engine manual for the correct plug type and gap specifications.
• Clean the engine regularly with a cloth or brush. Keep the top of the engine clean to permit proper air circulation. Remove all grass, dirt, and combustible debris from the muffler area.
• Engines stored between 30 and 90 days need to be treated with a gasoline stabilizer such as STA-BIL® to prevent deterioration and gum from forming in the fuel system or on essential carburetor parts.

Service

Blade Care

WARNING: When removing the cutting blade for sharpening or replacement, protect your hands with a pair of heavy gloves or use a heavy rag to hold the blade.

Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary. Follow the steps below for blade service.

1. Disconnect the spark plug boot from the spark plug. Turn the mower on its side, making sure that the air filter and the carburetor are facing up (not pointed toward the ground).
2. Remove the bolt and the blade bell support that hold the blade and the blade adapter to the engine crankshaft. See Figure 7-1.
3. Remove the blade and adapter from the crankshaft.
4. Remove the blade from the adapter for testing balance. Balance the blade on a round shaft screwdriver to check. Remove metal from the heavy side until it balances evenly. When sharpening the blade, follow the original angle of grind. Grind each cutting edge equally to keep the blade balanced.
5. Lubricate the engine crankshaft and the inner surface of the blade adapter with light oil. Slide the blade adapter onto the engine crankshaft. Place the blade on the adapter such that the side of the blade marked “Bottom” (or with part number) faces the ground when the mower is in the operating position. Make sure that the blade is aligned and seated on the blade adapter flanges. See Figure 7-1 inset.
6. Place the blade bell support on the blade. Align notches on the blade bell support with small holes in the blade.
7. Replace the hex bolt and tighten the hex bolt to torque: 450 in. lbs. min, 600 in. lbs. max.
   To ensure safe operation of your mower, periodically check the blade bolt for correct torque.

Off-Season Storage

The following steps should be taken to prepare your lawn mower for storage.

• Clean and lubricate the mower thoroughly as described in the lubrication instructions.
• Coat mower’s cutting blade with chassis grease to prevent rusting.
• Refer to the engine manual for correct engine storage instructions.
• If applicable, secure the side discharge chute to handle as shown in Figure 7-2.
• Store mower in a dry, clean area. Do not store next to corrosive materials, such as fertilizer.
