Safety Instructions
All Operators Must Read These 

Instructions Before Use

Always follow these safety guidelines. Failure to do so may 

result in serious bodily injury or death.

General Safety WARNINGS!

When using this electric lawn mower, basic safety precautions 

should always be followed to reduce the risk of fire, electric 

shock, and personal injury. These precautions include:

m

WARNING! 

Do not operate without the entire grass 

collection bag, discharge guard, rear flap, or other safety 

protective devices in place and in proper working order.

m

WARNING! 

The use of any other accessory or 

attachment might increase the risk of injury.

m

WARNING! 

To reduce the risk of injury, inspect the 

grass collection bag frequently and replace with recommended 

replacement if there are signs of wear or deterioration.
Before using the lawn mower, take the time to familiarize 

yourself with the controls, especially how to stop the lawn 

mower in an emergency. The only individuals who should use 

the lawn mower are those who have a thorough understanding 

of the instructions and who know how to operate the machine. 

Children should never be allowed access to the lawn mower.
Retain this manual for future reference and reread it at the start 

of each mowing season.

FOR DOUBLE-INSULATED  

LAWN MOWERS

1.  Replacement parts – When servicing this unit, use only 

identical replacement parts. Replace or repair damaged 

cords immediately.

2.  Polarized plug – Polarized appliance connections reduce 

the risk of electric shock. This lawn mower has a polarized 

plug (one blade is wider than the other) and will require the 

use of a polarized extension cord. There is only one way 

the lawn mower’s plug will fit into a polarized extension 

cord. If the plug does not fit fully into the extension cord, 

reverse the plug. If the plug still does not fit, obtain a 

correct polarized extension cord. A polarized extension 

cord will require the use of a polarized wall outlet. There 

is only one way the plug will fit into a polarized wall 

outlet. If the plug does not fit fully into the wall outlet, 

reverse the plug. If the plug still does not fit, contact a 

qualified electrician to install the proper wall outlet. Do not 

change the equipment plug, extension cord receptacle, or 

extension cord plug in any way.

m

WARNING! 

Contact with moving parts may cause 

entanglement, dismemberment, or other serious bodily 

injury. Always keep body parts (i.e. hands, feet) a safe 

distance away from moving parts. Ensure all covers and 

guards are securely in place before use.

Hot surfaces (i.e. the motor) may ignite flammable or 

combustible items and cause a fire or explosion, which 

can result in serious bodily injury. Keep the lawn mower a 

safe distance away from flammable or combustible items 

until surfaces that are hot have completely cooled. Do 

not store the lawn mower near flammable or combustible 

items.

A damaged blade or worn blade nut may break off the lawn 

mower assembly and cause serious injury. Replace the 

damaged blade or blade nut before using the lawn mower.

FOR ALL LAWN MOWERS

1.  Avoid dangerous conditions – Do not use the lawn 

mower in the rain or when the grass is damp or wet.

2.  Keep children, bystanders, and pets away – Always 

keep children and spectators a safe distance away from 

the lawn mower during operation and as the machine 

cools.

3.  Dress properly – Always wear personal safety gear (i.e. 

glasses, rubber gloves, protective footwear, and dust 

masks) and proper clothing when using the lawn mower. 

Loose clothing, long hair, or jewelry may get caught in the 

moving parts. Wear a protective covering to contain long 

hair.

4.  Use the right appliance – Do not use the lawn mower 

for any applications other than those for which it was 

intended.

5.  Do not force the lawn mower – It will perform better with 

less likelihood of personal or mechanical injury if it is used 

at the rate for which it was designed.

6.  Do not overreach – Keep proper footing and balance at 

all times. 

7.  Stay alert – Always be alert and watch what you are 

doing. Use common sense. Do not operate the lawn
