OPERATION

BLADE CONTROL

The blade control is attached to the upper handle of the mower. Depress and hold 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 operation.

DRIVE CONTROL

The drive control is located on the upper handle and is used to engage the drive. Pushing the control forward will engage the drive. Once pressure is released from the control it will return to the neutral position and the drive will be disengaged.

CUTTING HEIGHT ADJUSTMENT LEVER

The cutting height adjustment lever is located above the right rear wheel. To adjust the cutting height, refer to the Assembly Section.

DECK WASH

Your mower's deck is equipped with a water port on its surface as part of its deck wash system. Use the deck wash to rinse grass clippings from the deck's underside.

MULCHING COVER

The mulching cover 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 COVER

Your mower is shipped as a mulcher. To discharge the grass clippings to the side instead, follow the instructions in the Assembly section to attach the side discharge cover.

WARNING

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

RECOIL STARTER

The recoil starter is attached to the right upper handle. Stand behind the unit, depress and hold the blade control handle, then pull the recoil starter rope to start the unit.

WARNING

Make sure no one other than the operator is standing near the lawn mower while starting engine or operating mower. Never run 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 engine and lawn mower.

TO START ENGINE

1. Standing behind the mower, pull the blade control handle back against the upper handle (Figure 11).

2. While holding the blade control against the upper handle, grasp the recoil starter handle and pull rope out with a rapid, continuous, full arm stroke (Figure 11). Keeping a firm grip on the starter handle, let the rope rewind slowly. Repeat until engine starts. Let the rope rewind each time slowly.

Figure 11

WARNING

Keep a firm grip on the starter cord handle to prevent rapid retraction of starter |cord (kickback). Rapid retraction can pull hand and arm toward engine faster than you can let go, and result in broken bones, fractures, bruises or sprains.

TO STOP 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.

USING YOUR LAWN MOWER

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

WARNING

The operation of any lawn mower 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.

WARNING

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

Using Your Lawn Mower

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

1. Hold the blade control against the upper handle (Figure 11).

2. Start the engine (Figure 11).

3. Once the engine is running, pull and hold the drive control handle together with the blade control handle to propel the mower forward at the speed set on the speed control lever (Figure 11). Once pressure is released from the drive control it will return to the neutral position and the drive will be disengaged.

Using as Mulcher

For mulching grass, remove the grass catcher and side discharge chute from 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 grass catcher following instructions in the Assembly Section. Grass

clippings will automatically collect in bag as you run mower. Operate mower until grass bag is full.

2. Stop engine completely by releasing the blade control. Make sure that the unit

has come to a complete stop.

3. Lift discharge door and pull grass bag up and away from the mower to remove the bag. Dispose of the grass clippings and reinstall the bag when complete.

NOTE: Make sure to clean any excess grass from around the rear opening of the mower, especially between the transmission cover and sidewall on the left hand side and along the bottom, to ensure tight fit of bag onto mower.

Variable Drive Control

Ground speed varies with terrain, slope, grass height, etc. Increasing or decreasing the mower speed allows you to maintain the desired speed under changing mowing conditions. Four speeds are available, position 1 is slowest speed, position 4 is the fastest speed.

With the engine running and the blades rotating, set the drive control lever to position 1. Push the drive control handle forward to propel the mower. Ground speed will increase as the drive control lever is moved from position 1 to position 4 (Figure 12).

Release the drive control handle to disengage the drive when mowing around trees and obstacles. Push the mower around obstacles for better control.

SERVICE AND MAINTENANCE

DECK WASH

1. Push the mower to a level, clear spot on your lawn, near enough for your garden hose to reach. Remove the grass bag if attached.

CAUTION

Make sure the discharge chute is directed AWAY from your house, garage, parked cars, etc.

2. Thread the hose coupler (user-supplied) onto the end of your garden hose.

3. Attach the hose coupler to the water port on your deck's surface (Figure 13).

4. Turn the water on.

5. Start the engine as described in the Operation section.

6. Run the engine for a minimum of two minutes, allowing the underside of the cutting deck to thoroughly rinse.

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

8. Turn the water off and detach the hose coupler from the water port on your deck's surface.

After cleaning your deck, restart the mower. Keep the engine and blade running for a minimum of two minutes, allowing the underside of the cutting deck to thoroughly dry.

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 spark plug boot from spark plug. Turn mower on its side making sure that the air filter and the carburetor are facing up.

2. Remove the bolt and the blade bell support which hold the blade and the blade adapter to the engine crankshaft (Figure 14).

3. To be careful not to lose or remove self propel pulley and washers.

4. Remove 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 14 insert.

6. Place blade bell support on the blade. Align notches on the blade bell support with small holes in blade.

7. Replace hex bolt and tighten hex bolt to torque: 29.5-33.2 ft-lb (40-45 Nm) max.

WARNING

An unbalanced blade will cause excessive vibration when rotating at high speeds. It may cause damage to mower and could break causing personal injury.
