6. Never operate the mower in bare feet, sandals, slippery or light-weight (e.g. canvas) shoes.
7. Never overfill fuel tank. Fill tank to no more than 1” (2.5 cm) below the bottom of filler neck to allow space for fuel expansion.
8. Replace the gasoline cap and tighten it securely.
9. Use only accessories and attachments approved for this mower by the mower manufacturer. Read, understand and follow all instructions provided with the approved accessory or attachment.

Operating

1. Data indicates that operators, aged 65 years and above, are involved in a large percentage of mower-related injuries. These operators should evaluate their ability to operate the mower safely enough to protect themselves and others from serious injury.

2. Many injuries occur as a result of the mower being pulled over the foot during a fall caused by slipping or tripping. Do not hold on to the mower if you are losing your balance or footing; immediately release the handle.

3. Never pull the mower back toward you while you are walking. If you must back the mower away from a wall or obstruction first look down and behind to avoid tripping and then follow these steps:
   a. Step back from the mower to fully extend your arms.
   b. Be sure you are well balanced with sure footing.
   c. Pull the mower back slowly, no more than halfway toward you.
   d. Repeat these steps as needed.

4. Do not engage the drive control (if equipped) while starting the engine.

5. The blade control is a safety device. Never attempt to bypass its operation. Doing so makes the safety device inoperative and may result in personal injury through contact with the rotating blade. The blade control must operate freely in both directions and automatically return to the disengaged (off) position when released. The cutting blade continues to rotate for up to three seconds after the blade control is released. Never place any part of othe body in the blade area until you are certain the blade has stopped rotating.

6. If the mower should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.

7. Never operate a mower without the proper trail shield, discharge cover, grass catcher, blade control or other safety protective devices in place and working. Never operate a mower with damaged safety devices. Failure to do so can result in personal injury.

8. When starting the engine, pull cord slowly until resistance is felt, then pull rapidly. Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go. Broken bones, fractures, bruises or sprains could result.

9. Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade(s) can amputate hands and feet.

10. Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain or hidden objects could cause a slip and/or trip accident. Tall grass can hide obstacles.

11. Your mower is designed to cut normal residential grass of a height no more than 7” (17.5 cm). Do not attempt to mow through unusually tall, dry grass (e.g., pasture) or piles of dry leaves.

12. Plan your mowing pattern to avoid the discharge of material toward roads, sidewalks, helpers, and the like. Avoid discharging material against a wall or obstruction which may cause discharged material to ricochet back toward the operator.

13. Shut the engine off and wait until the blade comes to a complete stop before removing the grass catcher or unclogging the chute. The cutting blade continues to rotate for up to three seconds after the blade control is released. Never place any part of the body in the blade area until you are certain the engine is off and the blade has stopped rotating.

14. A missing or damaged discharge door, chute or mulch plug can cause blade contact or thrown object injuries.

15. Do not operate the mower without the discharge door, chute, mulch plug or the entire grass catcher in its proper place.

16. Stop the mower blade when crossing gravel drives, walksor roads and while not cutting grass.

17. Mow only in daylight or good artificial light.

18. Do not operate the mower while under the influence of alcohol or drugs.

19. The muffler and engine become very hot and can cause serious burn injuries. Do not touch. Allow the mower to cool for at least five minutes before storing or attempting
    any service.

20. Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas.

Children

1. Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the mower and the mowing activity. They do not understand the dangers. Never assume that children will remain where you last saw them.
2. Keep bystanders, children and pets inside while the mower is in operation under the watchful care of a responsible adult other than the operator. Stop mower if anyone enters the area.
3. Be alert and turn the mower off if a child or bystander enters the area.
4. Never allow children under 14 years of age to operate this mower. Children 14 and over should read and understand the instructions and safe operation practices in this manual and on the mower and should be trained and supervised by an adult.
5. This mower is a precision piece of power equipment, not a plaything. Therefore, exercise extreme caution at all times. This mower has been designed to perform one job: to mow grass. Do not use it for any other purpose.
6. Use extreme care when approaching blind corners, doorways, shrubs, trees or other objects that may block your vision of a child who may run into the path of the mower.
7. Keep children away from hot or running engines. They can suffer burns from a hot engine or muffler.
8. If your mower is equipped with an Electric Start Push Key, remove the key when the mower is unattended to prevent unauthorized operation. Make certain the key is inaccessible to small children.

Slope Operation for Walk-Behind Mowers

1. Slopes are a major factor related to slip and fall accidents which can result in severe injury or death. All slopes require extra caution. If you feel uneasy on the slope, do not mow it.
2. For your safety, measure any slope before using the mower on the sloped area. Use a slope measuring device in addition to the slope gauge included as part of this manual to measure slopes before operating this mower on a sloped or hilly area. Smartphone applications can be also utilized to measure slopes. If the slope is greater than 15 degrees (25%) as shown on the slope gauge or a slope measuring device, do not operate this mower on that area or serious injury could result.
3. Do not mow on slopes greater than 15 degrees (25%).
4. Only mow across slopes, never mow up and down slopes.
5. The mower may speed up when turning downhill, always turn uphill. Maintain control of the mower at all times.
6. Do not mow on wet grass. Unstable footing could cause slipping.
7. Do not operate the mower under any conditions where traction or stability is in question. Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your balance or footing, release the blade control handle immediately and the blade will stop rotating within three (3) seconds.
8. Stay at least 3 feet (1 meter) from drop-offs, ditches, embankments or the edge of the water. You could lose your balance or footing.

Fire & Fuel

1. To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately.
2. Extinguish all cigarettes, cigars, pipes and other sources of ignition.
3. Only use an approved portable fuel (gasoline) container. Use only containers certified by EPA, CARB, and/or OSHA.

Engine Maintenance Refer to the Engine Operator’s Manual packed with your mower for a detailed description of all engine-related service specifications.
Clean Engine

• Daily or before every use, clean grass, chaff or accumulated debris from the engine. Keep linkage, spring, and controls clean. Keep area around and behind muffler free of any combustible debris
• Keeping the engine clean allows air movement around the engine.
• Engine parts should be kept clean to reduce the risk of overheating and ignition of accumulated debris.

CAUTION Do not use water to clean engine parts. Water could contaminate fuel system. Use a brush or dry cloth.
Mower Maintenance
Deck Wash (If Equipped)
Your mower’s deck may be equipped with a deck wash system. Use the deck wash to rinse grass clippings from the deck’s underside and prevent the buildup of corrosive chemicals. Complete the following steps AFTER EACH MOWING:

1. Push the mower to a level, clear location on your lawn. Ensure your garden hose can reach your mower.
   **CAUTION** Make certain the mower’s discharge chute is directed AWAY from your house, garage, parked cars, etc.

2. Remove the fast attach deck wash nozzle from the mower deck and thread it onto the end of your garden hose.

3. Attach the garden hose with the deck wash nozzle to the water port on your deck’s surface. See Figure 13.

4. Turn the water ON.

5. Start the engine as described in the Engine Operator’s Manual.

6. Run the engine for a minimum of two minutes, allowing the underside of the cutting deck to thoroughly rinse. Figure 13 d

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

8. Turn the water OFF and detach the deck wash nozzle from the water port on your deck’s surface.

9. 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.

Deck Cleaning
At least once a season cleans the underside of the mower deck to prevent the build-up of grass clippings or other debris.

1. Allow the engine to run until it is out of fuel. Do not attempt to pour fuel from the engine. Disconnect spark plug wire. Refer to Engine Operator’s Manual.

2. Turn the mower on its side keeping the muffler side down and making sure that the air filter and the carburetor are facing up. Hold mower firmly.

3. Scrape and clean the underside of the deck with a suitable tool. Do not spray with water.
   IMPORTANT: Do not use a pressure washer or garden hose to clean your mower. These may cause damage to bearings or the engine. The use of water will results in shortened life and reduce serviceability.

4. Put the mower back on its wheels on the ground.

Drive Adjustment
The drive system consists of pulleys, a belt, and a cable linking the transmission to the drive control. As these components wear, an adjustment may be needed. To adjust the drive perform the following:

1. Weak drive. See Figure 14 –
   a. Loosen jam nut (a).
   b. Thread adjustment nut (b) down, towards the mower base to lengthen the drive cable. Figure 14 c. Securely tighten jam nut. (a) (b)

2. Drive control is tight or difficult to pull back. See Figure 15 –
   a. Loosen jam nut (a).
   b. Thread adjustment nut (b) up, towards the handle to shorten the drive cable.
   c. Securely tighten jam nut. Figure 15

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.
