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 

mower when you are tired or under the influence of 

alcohol or drugs.

8.  Disconnect the lawn mower – Disconnect the lawn 

mower from the power supply when it is not in use, 

before servicing, when changing accessories, and when 

performing any other maintenance task.

9.  Store idle lawn mower indoors – When not in use, the 

lawn mower should be stored indoors in a dry, locked 

place out of the reach of children.

10. Maintain the lawn mower with care – Keep cutting 

edges sharp and clean for best and safest performance.

Inspect the lawn mower cord periodically and if damage 

is found have it repaired by an authorized service facility. 

Extension cords should also be inspected periodically 

and immediately replaced if damaged. Keep handles dry, 

clean, and free from oil and grease.

Electrical Safety

1.  Ground fault circuit interrupter (GFCI) protection should 

be provided on the circuit(s) or outlet(s) to be used for 

the lawn mower. Receptacles are available having built-in 

GFCI protection and may be used for this  

measure of safety.

2.  To reduce the risk of electric shock, this appliance has 

a polarized plug (i.e. one blade is wider than the other). 

Use this appliance only with a polarized, UL-listed (CSA 

certified in Canada) extension cord recommended for 

outdoor use. The appliance plug will fit into a polarized 

extension cord only one way.

  If the appliance 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. The 

extension cord plug will fit into the polarized wall outlet 

only one way. 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 modify the appliance plug, extension cord 

receptacle, or extension cord plug in any way.

3.  To prevent electric shock, use only with an extension cord 

suitable for outdoor use, such as SW, SOW, STW, STOW, 

SJTW, or SJTOW.

  Before use, check that the extension cord is in good 

condition. When using an extension cord, make sure to 

use one heavy enough to carry the current your product 

will draw. For lengths less than 50 feet, a No. 14 AWG 

extension cord should be used. An undersized cord will 

cause a drop in line voltage resulting in loss of power and 

overheating.

4.  To prevent the appliance cord from disconnecting from the 

extension cord during operation, make a knot with the two 

cords as shown in Table 1.

5.  Do not abuse the cord. Never pull the lawn mower by the 

cord or yank the cord to disconnect it from the receptacle. 

Keep the cord away from heat, oil, and sharp edges.

Double-Insulated Appliances

In a double-insulated appliance, two systems of insulation 

are provided instead of grounding. No grounding means are 

provided on a double-insulated appliance, nor should a means 

for grounding be added to the appliance. Servicing a double-

WARNING! 

m

Electric shock may cause SEVERE INJURY or 

DEATH. Heed these warnings:

•  Do not allow any part of the lawn mower to make 

contact with water while it is in operation. If the 

appliance becomes wet while turned off, wipe dry 

before starting. 

•  Use only a UL-rated extension cord for outdoor, 

all-weather use. Do not use an extension cord over 

100 ft (30 m).

•  Do not touch the appliance or its plug with wet hands 

or while standing in water. Wearing rubber boots 

offers some protection.
