Safe Handling of Gasoline:  
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. If you feel uneasy on a  
slope, do not mow it. Before operating this unit on a  
slope or hilly area, use the slope gauge on page 6 to  
measure slopes. If the slope is greater than 15 degrees,  
do not mow it.  
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.  
2. Wash your skin and change clothes immediately.  
3. Use only an approved gasoline container.  
4. Never fill containers inside a vehicle or on a truck or  
trailer bed with a plastic liner. Always place  
containers on the ground away from your vehicle  
before filling.  
5. If possible, remove gas-powered equipment from  
the truck or trailer and refuel it on the ground. If this  
is not possible, then refuel such equipment on a  
trailer with a portable container, rather than from a  
gasoline dispenser nozzle.  
Do:  
1. Mow across the face of slopes; never up and down.  
Exercise caution when changing direction.  
2. Watch for holes, ruts, rocks, hidden objects, or  
bumps which can cause you to slip or trip. Tall  
grass can hide obstacles.  
3. 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  
within 3 seconds.  
6. Keep the nozzle in contact with the rim of the fuel  
tank or container opening at all times until fueling is  
complete. Do not use a nozzle lock-open device.  
7. Extinguish all cigarettes, cigars, pipes and other  
sources of ignition.  
Do Not:  
1. Do not mow near drop-offs, ditches or  
embankments, you could lose your footing or  
balance.  
8. Never fuel machine indoors because flammable  
vapors will accumulate in the area.  
4

9. Never remove gas cap or add fuel while the engine  
is hot or running. Allow engine to cool at least two  
minutes before refueling.  
10. Never over fill fuel tank. Fill tank to no more than ½  
inch below bottom of filler neck to provide space for  
fuel expansion.  
11. Replace gasoline cap and tighten securely.  
12. If gasoline is spilled, wipe it off the engine and  
equipment. Move unit to another area. Wait 5  
minutes before starting the engine.  
13. Never store the machine or fuel container inside  
where there is an open flame, spark or pilot light as  
on a water heater, space heater, furnace, clothes  
dryer or other gas appliances.  
lead to improper performance and compromise  
safety!”  
4. Mower blades are sharp and can cut. Wrap the  
blade or wear gloves, and use extra caution when  
servicing them.  
5. Keep all nuts, bolts, and screws tight to be sure the  
equipment is in safe working condition.  
6. Never tamper with safety devices. Check their  
proper operation regularly.  
7. After striking a foreign object, stop the engine,  
disconnect the spark plug wire and ground against  
the engine. Thoroughly inspect the mower for any  
damage. Repair the damage before starting and  
operating the mower.  
14. To reduce fire hazard, keep mower free of grass,  
leaves, or other debris build-up. Clean up oil or fuel  
spillage and remove any fuel soaked debris.  
15. Allow a mower to cool at least 5 minutes before  
storing.  
8. Never attempt to make a wheel or cutting height  
adjustment while the engine is running.  
9. Grass catcher components, discharge cover, and  
trail shield are subject to wear and damage which  
could expose moving parts or allow objects to be  
thrown. For safety protection, frequently check  
components and replace immediately with original  
equipment manufacturer’s (O.E.M.) parts only,  
listed in this manual. “Use of parts which do not  
meet the original equipment specifications may  
lead to improper performance and compromise  
safety!”  
10. Do not change the engine governor setting or  
overspeed the engine. The governor controls the  
maximum safe operating speed of the engine.  
11. Maintain or replace safety and instruction labels, as  
necessary.  
General Service:  
1. Never run an engine indoors or in a poorly  
ventilated area. Engine exhaust contains carbon  
monoxide, an odorless and deadly gas.  
2. Before cleaning, repairing, or inspecting, make  
certain the blade and all moving parts have  
stopped. Disconnect the spark plug wire and  
ground against the engine to prevent unintended  
starting.  
3. 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 manufacture’s (O.E.M.) blade only,  
listed in this manual. “Use of parts which do not  
meet the original equipment specifications may  
12. Observe proper disposal laws and regulations.  
Improper disposal of fluids and materials can harm  
the environment.

Using Your Lawn Mower  
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.  
You can use your mower as a mulcher or a rear  
bagger or for side discharge of grass.  
Be sure that the 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.  
Before Starting Mower  
For best results, do not cut wet grass because it  
tends to stick to the underside of the mower.  
For a healthy lawn, always cut off one-third or less  
of the total length of the grass. Lawn should be  
trimmed in fall as long as there is growth.  
Attach spark plug wire to spark plug. Make certain  
the metal cap on the end of the spark plug wire  
(inside the rubber boot) is fastened securely over  
the metal tip on the spark plug.  
WARNING: If the mower strikes a foreign  
object, stop the engine. Remove spark plug  
wire from the spark plug and thoroughly inspect  
for any damage. Repair the damage promptly  
before restarting and operating the mower.  
Throttle Speed  
Your lawn mower engine is equipped with a constant  
speed throttle, which is set at full throttle for best  
performance.  
Starting Engine  
Adjusting Cutting Height  
WARNING: Be sure no one other than the  
operator is standing near the lawn mower while  
starting engine or operating mower.  
Refer to height adjustments section of this manual on  
page 14 for instruction on how to adjust the cutting  
height and the handle height.  
For best results in mowing, keep the cutting height  
position high until you can determine a suitable height.  
WARNING: Never run engine indoors or in  
enclosed, poorly ventilated areas. Engine  
exhaust contains carbon monoxide, an  
odorless and deadly gas.  
Bagging Grass Clippings  
You can use the grass catcher bag to collect clippings  
while you are operating the mower.  
WARNING: Keep hands, feet, hair and  
loose clothing away from any moving parts on  
engine and lawn mower.  
Attach grass catcher following instructions on page  
8. Grass clippings will automatically collect in the  
bag as you run the mower. Operate the mower till  
the grass bag is full.  
Push primer three times. Wait about two seconds  
between each push. In cold weather around 55o F  
or below, prime five times. Do not prime to restart a  
warm engine after a short shutdown.  
Once the bag is full, stop the engine and the mower  
completely. Lift discharge door and pull grass bag  
up and away from the mower to dispose of the  
grass clippings.  
Standing behind the mower, depress the blade  
control handle and hold it against the upper handle.

exceed 150o F.  
Cleaning Mower  
The underside of the mower deck should be cleaned  
after each use to prevent any build-up of grass  
clippings, leaves, dirt, or other debris. If this debris is  
allowed to accumulate, it will result in rust and  
corrosion.  
Lubrication  
NOTE: We do not recommend the use of pressure  
washers or garden hose to clean your unit. These may  
cause damage to pulleys, bearings, or the engine. The  
use of water will result in shortened life and reduce  
serviceability.  
Disconnect spark plug wire.  
Drain the gasoline from the lawn mower, or place a  
piece of plastic under the gas cap.  
Lube  
Tip the mower so that it rests on the housing. Keep  
the side with the air cleaner facing up. Hold the  
mower firmly.  
Lube  
Scrape and clean the underside of the deck with a  
suitable tool. Do not spray with water.  
Put the mower back on its wheels on the ground. If  
you had put plastic under the gas cap, make sure to  
remove it now.  
WARNING: Never tip the mower more than  
90 degrees in any directions 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.

Adjusting Carburetor  
If the engine is running rough, minor adjustments to the  
carburetor may be required to compensate for  
differences in fuel, temperature, altitude and load.  
Adjusting Cutting Height  
IMPORTANT: All wheels must be placed in the same  
relative position. For rough or uneven lawns, move the  
height adjustment lever to a higher position. This will  
help stop scalping of the grass.  
NOTE: Dirty air cleaner may cause an engine to run  
rough.Before adjusting carburetor, check air cleaner.  
To adjust the carburetor, please follow the  
recommendations and instructions on carburetor  
adjustment in the engine manual.  
An adjusting plate and thumb lever at each wheel  
provides cutting height adjustment. Each adjusting  
plate has nine height positions. Height of cut will be  
changed when you move the thumb lever from one  
position to another.  
WARNING: If any adjustments are made to  
the engine (e.g. carburetor) while the engine is  
running, keep clear of all moving parts. Be  
careful of heated surfaces like the muffler.  
Simply depress the lever towards the wheel and  
move the lever assembly to desired position. See  
SECTION 8: OFF-SEASON STORAGE

season or if the unit will not be used for 30 days or  
more. Store the mower in a clean, dry area.

off-season storage of the engine.  
Change oil if it has not been changed in the last  
three months. For instructions on how to change oil,  
refer to the engine manual.

You can fold your mower’s handle for convenient  
storage: Remove the starter rope from the rope  
guide; loosen the two hand knobs on the sides of  
the handle, and let the upper handle fold down to  
the rear. Move the hairpin clips to the outer hole in  
the weld pins on the handle mounting brackets.  
Spread the sides of the lower handle, and push it  
forward and down.  
Other  
Do not store gasoline from one season to another.  
Replace your gasoline can if it starts to rust. Rust  
and/or dirt in the gasoline will cause problems.
