Safe  

Operation 

Practices

General Operation

1.  Read this operator’s manual  carefully in its entirety before 

attempting to assemble this machine. Read, understand, and 

follow all instructions on the machine and in the manual(s) 

before operation. Keep this manual in a safe place for future 

and regular reference and for ordering replacement parts.

2.  Be completely familiar with the controls and the proper use of 

this machine before operating it. 

3.  This machine is a precision piece of power equipment, not a 

plaything. Therefore, exercise extreme caution at all times. 

Your unit has been designed to perform one job: to mow grass. 

Do not use it for any other purpose.

4.  Never allow children under 14 years old to operate this 

machine. Children 14 years old and over should read and 

understand the instructions in this manual and should be 

trained and supervised by a adult.

5.  Only responsible individuals who are familiar with these rules 

of safe operation should be allowed to use this machine.

6.  Thoroughly inspect the area where the equipment is to be 

used. Remove all stones, sticks, wire, bones, toys and other 

foreign objects which could be tripped over or picked up 

and thrown by the blade. Thrown objects can cause serious 

personal injury.

7.  Plan your mowing pattern to avoid discharge of material toward 

roads, sidewalks, bystanders and the like. Also, avoid discharg-

ing material against a wall or obstruction which may cause 

discharged material to ricochet back toward the operator. 

8.  To help avoid blade contact or a thrown object injury, stay 

in the operator zone behind the handles and keep children, 

bystanders, helpers and pets at least 75 feet from the mower 

while it is in operation. Stop machine if anyone enters the area.

9.  Always wear safety glasses or safety goggles during operation 

and while performing an adjustment or repair to protect your eyes. 

Thrown objects which ricochet can cause serious injury to the 

eyes.

10. Wear sturdy, rough-soled work shoes and close-fitting slacks 

and shirts. Shirts and pants that cover the arms and  legs 

and steel-toed shoes are recommended. Never operate this 

machine in bare feet, sandals, slippery or light weight (e.g. 

canvas) shoes.

11.  Do not put hands or feet near rotating parts or under the cutting 

deck. Contact with the blade can amputate hands and feet.

12. A missing or damaged discharge cover can cause blade 

contact or thrown object injuries.

13. 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. 

14.  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 half way toward you.
d.  Repeat these steps as needed.

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

drugs.

16. Do not engage the self-propelled mechanism on units so 

equipped while starting engine.

17.  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.

18. Never operate the mower in 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.

19.  Mow only in daylight or in good artificial light. Walk, never run. 
20. Stop the blade when crossing gravel drives, walks or roads.
21.  If the equipment should start to vibrate abnormally, stop the 

engine and check immediately for the cause. Vibration is gener-

ally a warning of trouble.

22. 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 a few seconds after the 

engine is shut off. Never place any part of the body in the blade 

area until you are sure the blade has stopped rotating.

23. Never operate mower without proper trail shield, discharge cover, 

grass catcher, 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.

24. Muffler and engine become hot and can cause a burn. Do not 

touch.

25. Never attempt to make a wheel or cutting height adjustment while 

the engine is running.

26. Only use parts and accessories made for this machine by the 

manufacturer. Failure to do so can result in personal injury.

27. 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.

28. If situations occur which are not covered in this manual, use care 

and good judgment.  Call customer assistance for the name of 

your nearest servicing dealer.

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. For your safety, use 

the slope gauge included as part of this manual to measure slopes 

before operating this unit on a sloped or hilly area. If the slope is 

greater than 15 degrees, do not mow it.

Do:

1.  Mow

 across the face of slopes; never up and down. Exercise 

extreme caution when changing direction on slopes.

2.  Watch for holes, ruts, rocks, hidden objects, or bumps which can

 

cause you to slip or trip. Ta

ll grass can hide obstacles.

WARNING:

 Engine Exhaust, some of its constituents, and certain vehicle components contain 

or emit chemicals known to the State of California to cause cancer and birth defects or other 
reproductive harm.
