Mowing Tips

m

WARNING! 

Inspect the area prior to mowing and 

remove all the stones, sticks, wires, and other debris that might 

be thrown by the rotating blade.
NOTE: A sharp blade will greatly enhance the performance of 

the lawn mower, especially when cutting tall blades of grass.

•  Be sure to check the blade periodically for signs of wear 

and sharpen it at least once per year, as described in the 

maintenance section.

• 

In order to prevent electric shock, do not operate the lawn 

mower in damp or wet conditions. 

•  Do not mow in a circle. Travel back and forth across the 

lawn following the path outlined below (Fig. 15).

•  When cutting thick grass, reduce your walking speed 

in order to allow for a more effective cut and a proper 

discharge of the clippings. For a healthy lawn, always  

cut off one-third or less from the total length of the grass. 

The average lawn should be approximately 1.5 to 2 in.  

(3.8 cm to 5 cm) long during cool months, and more than 

2 in. (5 cm) long during hot months. If there is growth,  

the lawn should be cut in the fall.

•  While mowing, make sure that the electric cable is always 

behind you and resting on the area of grass already cut.

•  The lawn will look better if it is always cut to the same 

height and in alternate directions.

•  When crossing any graveled area, release the switch bar 

lever to turn off the lawn mower. The stones can be picked 

up and thrown by the rotating blade.

•  Set the lawn mower to the highest cutting height when 

mowing on uneven ground or in tall weeds.

WARNING! 

If you strike a foreign object, stop the motor 

and disconnect the power cord. Thoroughly inspect the lawn 

mower for any damage. Repair any damage before operating 

the lawn mower. 

Maintenance

m

WARNING!

 Before cleaning, repairing, or inspecting the 

lawn mower, disconnect the power supply to the unit and verify 

that all moving parts have come to a complete stop.

General

•  Always keep the lawn mower clean and free of grass, dirt, 

or other debris.

•  Keep the handles dry, clean, and free of oil and grease. 
•  After each cutting session, remove accumulated grass 

clippings and debris using either a dry cloth or hand 

brush. You may also clean the equipment with a damp 

cloth. Do not use cleaning agents or harsh solvents as 

they may damage the equipment's plastic components. 

Make sure that no water penetrates the equipment's 

interior as intake of water can destroy the switch/plug 

mechanism and the electric motor.

•  Do not clean the lawn mower with running water, 

particularly with high-pressure water. 

•  Check all nuts, bolts, and screws for proper tightness 

before each use.

•  Frequently inspect the grass collection bag for signs of 

wear and replace immediately with a genuine Snow Joe

 part if damage is found.

•  Replace excessively worn or damaged parts immediately.
