ENGINE SAFETY
WARNING This machine is equipped with
an internal combustion engine and should not be used on or near any unimproved forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrestor meeting applicable local or state laws (if any).
If a spark arrestor is used, it should be maintained in effective working order by the operator. In the State of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands.
Never start or run the engine inside a closed area. The exhaust fumes are dangerous, containing carbon monoxide, an odorless and deadly gas.
Operate this unit only in a well-ventilated outdoor area.
Do not tamper with the engine to run it at excessive speeds. The maximum engine speed is preset by the manufacturer and is within safety limits. See engine manual.
The muffler keeps the noise levels to a minimum and sends the exhaust fumes away from the operator. Do not use the product if
7 | Safety

the muffler is missing or defective. A defective muffler increases the noise level and the risk of fire. Examine the muffler regularly to make sure that it is attached correctly and not damaged.
Muffler and engine become hot and can cause burns. Do not touch.
Do not modify engine. To avoid serious injury or death, do not modify engine in any way. Tampering with the governor setting can lead to a runaway engine and cause it to operate at unsafe speeds. Never tamper with factory setting of engine governor.
FUEL SAFETY Fuel is highly flammable, and its vapors can explode if ignited. Take precautions when using to reduce the chance of serious personal injury.
When refilling or draining the fuel tank, use an approved fuel storage container while in a clean, well-ventilated outdoor area. Do not smoke, or allow sparks, open flames, or other sources of ignition near the area while adding fuel or operating the unit. Never fill the fuel tank indoors.
Keep grounded conductive objects, such as tools, away from exposed, live electrical parts and connections to avoid sparking or arcing. These events could ignite fumes or vapors.
Always stop the engine and allow it to cool before filling the fuel tank. Never remove the cap of the fuel tank or add fuel while the engine is running or when the engine is hot. Do not operate the machine with known leaks in the fuel system.
Loosen the fuel tank cap slowly to relieve any pressure in the tank.
Never overfill the fuel tank. Fill the tank to no more than 1/2″ below the bottom of the filler neck to provide space for expansion as the heat of the engine can cause fuel to expand.
Replace all fuel tank and container caps securely and wipe up spilled fuel. Never operate the unit without the fuel cap securely in place.
Avoid creating a source of ignition for spilled fuel. If fuel is spilled, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated.
Do not start the product if there is fuel or engine oil on the product. Remove the unwanted fuel/oil and let the product dry.
When fuel is spilled on yourself or your clothes, wash your skin and change clothes immediately.
Store fuel in containers specifically designed and approved for this purpose.

Walk-Behind Lawn Mower » Operator’s Manual

Store fuel in a cool, well-ventilated area, safely away from sparks, open flames, or other sources of ignition.
Never store fuel or a machine with fuel in the tank inside a building where fumes may reach a spark, open flame, or any other source of ignition, such as a water heater, furnace, or clothes dryer. Allow the engine to cool before storing in any enclosure.

SPECIFIC SAFETY RULES

OPERATION SAFETY
This machine has been designed to perform one job: to mow grass. Do not use it for any other purpose.

protective footwear that will protect your feet and improve your footing on slippery surfaces. Keep proper footing and balance at all times. This enables better control of the machine in unexpected situations.

Operate the product only in daylight or in good artificial light. Walk, never run.

Do not engage the self-propelled mechanism on machines so equipped while starting engine.

Stop the blade when crossing gravel drives, walks or roads.
A missing or damaged discharge cover can cause blade contact or thrown object injuries.
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 falling: release the handle immediately.
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 mower to fully extend your arms forward.
b. Be sure you are well balanced with sure footing.
c. Pull the mower back slowly, no more than half way toward you.
d. Repeat these steps as needed.
Do not touch parts that are hot from operation. Allow parts to cool before attempting to maintain, adjust, or service. Serious burns may result. Engine parts, especially the muffler, become extremely hot during operation. Allow engine and muffler to cool before touching.

The blade control handle 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 handle must operate easily in both directions and automatically return to the disengaged position when released.
Never operate the mower on wet grass. Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your footing, release the blade control handle immediately and the blade will stop rotating within three seconds.
Shut the engine off and wait until the blade comes to a complete stop before removing the grass bagger or unclogging the chute. The cutting blade continues to rotate for a few seconds after the blade control is released. Never place any part of the body in the blade area until you are sure the blade has stopped rotating.
Never operate mower without proper trail shield, discharge cover, grass bagger, blade control handle or other safety protective devices in place and working. Never operate mower with damaged safety devices. Failure to do so can result in personal injury.
Never attempt to make a wheel or cutting height adjustment while the engine is running.

Stay alert, watch what you are doing, and use common sense when operating the machine.
Do not overreach. Do not operate the machine while barefoot or when wearing sandals or similar lightweight footwear. Wear

When starting 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.

Safety | 8

If the equipment should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.
This manual cannot include all situations that can occur when you use the product. Be careful and use your common sense. Do not operate the product or do maintenance to the product if you are not sure about the situation. Contact Customer Support for assistance.
SLOPE OPERATION Slopes are a major factor related to slip and fall accidents, which can result in severe injury. Operation on slopes requires extra caution. The machine is heavy and can speed up when going downhill. Be prepared to maintain control of the machine. If you feel uneasy on a slope, do not mow it. If the slope is greater than 15 degrees, do not mow it.
Mow across the face of slopes, never up and down, to avoid loss of control. Exercise extreme caution when changing direction on slopes; watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip. Tall grass can hide obstacles.
Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your balance, release the blade control handle immediately and the blade will stop rotating.
Do not mow near drop-offs, ditches or embankments, because you could lose your footing or balance.
WORK AREA SAFETY Remove branches, twigs, stones and other objects from the lawn before you start to cut.
Keep persons, including children, and animals at a safe distance from the work area.
Objects that hit against the cutting equipment can be ejected and cause damage to persons and objects.
Do not use the product in bad weather, including fog, rain, moist or wet locations, strong winds, intense cold and risk of lightning. Doing work in bad weather can cause fatigue and dangerous conditions, such as slippery surfaces.
Examine your work area to make sure that your control of the product cannot be prevented.
Be careful of roots, stones, twigs, pits and ditches.
High grass can conceal obstacles.
Operate the product only in daylight or in good artificial light.
Do not operate the product on wet grass.

Be careful when you go near hidden corners and objects that can prevent your view.
Maintain a high level of caution when you reverse or pull the product in your direction.
MAINTENANCE SAFETY Before cleaning, repairing, or inspecting the product, stop the engine and make certain the blade and all moving parts have stopped. Disconnect the spark plug wire and ground against the engine and remove Electric Start Push Key (if equipped) to prevent unintended starting.
Check the blade and engine mounting bolts at frequent intervals for proper tightness. Also, visually inspect blade for damage (e.g., bent, cracked, worn). Replace blade with the original equipment manufacturer’s (O.E.M.) blade only, listed in this manual. Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safety!
Mower blades are sharp and can cut. Wrap the blade or wear gloves, and use extra caution when servicing them.
Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.
Accessories and changes to the product that are not approved by the manufacturer can cause serious injury or death. Do not alter the product. Always use accessories that are approved by the manufacturer.
Deflectors, guards and shields decrease the risk of objects being ejected from the product in the direction of the operator or other persons. Make sure the deflectors, guards and shields are not damaged and that no defects are in view, such as cracks, broken springs or missing hardware. Replace any damaged or missing parts.
If the maintenance is not done correctly and regularly, the risk of injury and damage to the product increases.

Figure 10

NOTE

For rough or uneven lawns, move the height adjustment

lever to a higher position. This will prevent you from

cutting the grass too close to the ground.

17 | Operation

STARTING THE ENGINE

WARNING

Be 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.

Refer to the Engine Operator’s Manual for detailed

instructions on starting and stopping the engine.

1. Starting primer bulb operation is important operation of the starting engine. For cold starting, slightly press the primer bulb one to three times in succession and quickly pull the recoil cable grip. For hot starting, directly pull the starter cable grip.
2. Pull the starter grip lightly until resistance is felt, then, briskly pull to syncline upper 30 degree out.
BASIC CUTTING PROCEDURE
· Always cut with a sharp blade for the best results. A blade that is not sharp cuts unevenly and lets the grass become yellow on the surface of the cut.
· Do not cut more than 1/3 of the length of the grass. This especially applies during dry periods. Cut first with the cutting height set high. Then examine the result and lower to an applicable height. If the grass is too long, operate slowly and cut two times if necessary.
· For very heavy cutting, decrease the width of the cut by making an overlap of the cut path and cutting slowly.
· Cut in different directions each time to prevent stripes in the lawn.
· Regularly hose the grass catcher with water and let dry before use. Pores in cloth grass catchers can become filled with dirt and dust with operation. The grass catcher will then collect less grass.
· The side discharging mode of your product is the best cutting mode. If you try to cut a large quantity of grass and the product does not operate correctly, or has decreased operation time, change the product to side discharging mode for better performance and operation time.
BLADE CONTROL
1. Standing behind the mower, squeeze the engine start/stop control lever against upper handle.
2. Holding the engine start/stop control lever firmly, grasp recoil starter handle and pull rope out with a rapid, continuous, full arm stroke. Keeping a firm grip on the starter handle, let the rope rewind slowly.

Walk-Behind Lawn Mower » Operator’s Manual

3. Pull the recoil starter until engine compression has become difficult to pull. Let the recoil return to the home position, then pull quickly to start the engine. Repeat steps as needed. Fully open the choke and set the throttle to the FAST position before operating the unit.

WARNING Rapid retraction of the starter
cord (kickback) will pull your hand and arm toward the engine faster than you can let go. Broken bones, fractures, bruises, or sprains could result.
USING AS MULCHER
For mulching grass, remove the side discharge chute from the mower. When you remove the side discharge chute, the mulch cover will close. 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.
SIDE DISCHARGE MODE
Open the mulch cover and install the side discharge deflector. (See Figure 11)

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 warranty, operator must maintain the lawn mower as instructed here.
· Changing of engine-governed speed will void engine warranty. · All adjustments should be checked at least once each season. · Periodically check all fasteners and make sure these are tight.
19 | Maintenance

LUBRICATION
1. Lubricate pivot points on the blade and drive controls at least once a season with light oil. These controls must operate freely in both directions. (See Figure 14)

Figure 14

Walk-Behind Lawn Mower » Operator’s Manual

2. The transmission is pre-lubricated and sealed at the factory and does not require lubrication.
3. Follow the Engine Operator’s Manual for lubrication schedule and instructions for engine lubrication.
DECK CARE
Clean underside of the mower deck after each use to prevent buildup of grass clippings or other debris. Follow steps below for proper cleaning.
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. Tip mower so that it rests on the housing. Keep the side with the air cleaner facing up. Hold mower firmly.
WARNING Never tip mower more than
90º in any direction and do not leave mower tipped for any length of time. Oil can drain into 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.
ENGINE CARE
A list of key engine maintenance jobs required for good performance by the mower are listed below. Follow the Engine Operator’s Manual for a detailed list and instructions. · Maintain oil level as instructed in Engine Operator’s Manual.
· Service air cleaner every 25 hours of use under normal conditions. Clean every few hours under extremely dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced. To service the air cleaner, refer to the Engine Operator’s Manual.
· Clean spark plug and reset the gap once a season. Spark plug replacement is recommended at the start of each mowing season. Check Engine Operator’s Manual for correct plug type and gap specifications.
· Clean 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 muffler area.
· Engines stored between 30 and 90 days need to be treated with a gasoline stabilizer to prevent deterioration and gum from forming in fuel system or on essential carburetor parts.

CLEANING THE GRASS CATCHER
Pores in cloth grass catchers can become filled with dirt and dust during operation. This causes the grass catcher to collect less grass. To prevent this, regularly hose the grass catcher off with water and let dry before using.
· Examine the grass catcher frequently for wear or deterioration. Replace if necessary.

CHANGING THE ENGINE OIL
See Maintenance schedule on page 19 for more information about when to change the oil. To change the oil, use the following procedure.

NOTE

Run the engine for a few minutes before changing the

oil to warm it. Warm oil flows better and carries more

contaminants. We recommend that you use API

SERVICE Category SJ class or high oil.

1. Move the machine to a level surface.
2. Refer to the maintenance safety section on page 9 before doing oil change.
3. Remove the dipstick by rotating the cap counterclockwise and pulling it out. (See Figure 15)

MAX MIN

Figure 15
Maintenance | 20

4. Tip the machine onto its side (so that the air filter is up) to drain the used oil from the oil-fill tube. (See Figure 16)

Figure 16
5. After draining the used oil, return the machine to the operating position.
6. Carefully pour about 3/4 of the engine capacity of oil into the oilfill tube.
7. Wait 3 minutes for the oil to settle in the engine.
8. Wipe the dipstick clean with a clean cloth. 9. Insert the dipstick into the oil-fill tube, then remove the dipstick.
10. Read the oil level on the dipstick. (See Figure 15)
· If the oil level on the dipstick is too low, carefully pour a small amount of oil into the oil-fill tube, wait 3 minutes, and repeat steps 8 through 10 until the oil level on the dipstick is correct.
· If the oil level on the dipstick is too high, drain the excess oil until the oil level on the dipstick is correct.

WARNING

If the oil level in the engine is too low or too high and you

run the engine, you may damage the engine.

11. Install the dipstick into the oil-fill tube securely. 12. Recycle the used oil properly.

BLADE CARE
WARNING Always stop the engine before
you do work on the blade. The blade continues to rotate after the throttle has been released. Make sure that the blade is fully stopped and disconnect the spark plug cap before you start work.
WARNING The blade is sharp; contact
with the blade can result in serious personal injury. Wear gloves when servicing the blade.
1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug. (See Figure 17)
Figure 17
2. Examine the blade whenever you run out of fuel. If the blade is damaged or cracked, replace it immediately. If the blade edge is dull or nicked, have it sharpened and balanced, or replace it.
3. Tip the machine onto its side with the air filter and carburetor facing up. Use a block of wood to hold the blade steady. (See Figure 18)

21 | Maintenance

Walk-Behind Lawn Mower » Operator’s Manual

NOTE

You will need a torque wrench to install the blade properly.

CAUTION Use only a replacement
blade approved by the manufacturer of your mower. Using a blade not approved by the manufacturer of your mower is hazardous, could damage your mower and void your warranty.

WARNING

Position the curved ends of the blade to point toward the

machine housing.

5. Install the new blade. Use a block of wood between the blade and lawn mower housing and tighten the blade bolt, turning clockwise. The recommended tightening torque is 45-55 Nm. (See Figure 20)

Figure 18
4. Remove the blade, saving all mounting hardware. Examine the blade support and blade bolt to see if there is damage. Examine the motor shaft to make sure that it is not bent. (See Figure 19)
