 WARNING: 

Do not mow a slope that has an angle of 

greater than 15° (a rise of approximately 2-1/2 ft. every 10 ft.). 
Mow across the face of a slope, and never up and down. 

Mowing Tips

NOTE: 

A sharp blade will greatly enhance the performance of 

the mower, especially when cutting high grass.

Be sure to check the blade and to sharpen it at least once per 
year, as described in the Maintenance section.

• Verify that the lawn is free of stones, sticks, wires, and 

other objects that could damage the blades or the motor 
before use.

These objects could be accidentally thrown by the mower in 
any direction, and could cause serious injury to the operator 
and to others.

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

mower in damp or wet conditions.

•  Do not mow in circles. Travel back and forth across the lawn.
• When cutting thick grass, reduce walking speed in order to 

allow for a more effective cut and proper discharge of the 
clippings. For a healthy lawn, always cut off one-third or less 
of the total length of the grass. The average lawn should 
be approximately 1.5 to 2 in. (3.8 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.

Mulching Tips

NOTE:

 INSPECT THE AREA WHERE THE MOWER IS TO 

BE USED AND REMOVE ALL STONES, STICKS, WIRE, 
AND OTHER DEBRIS THAT MIGHT BE THROWN BY THE 
ROTATING BLADE.

1.  

Release the switch to turn the mower OFF when 
crossing any graveled area (stones can be thrown by 
the blade).

2.  

Set mower to the highest cutting height when mowing 
on uneven ground or in tall weeds.

3.  

For effective mulching, do not cut wet grass, be-
cause it tends to stick to the underside of the deck, 
preventing proper mulching of grass clippings. New 
or thick grass may require a narrower cut. The ground 
speed should be adjusted to the condition of the 
lawn. If mowing has been delayed and the grass has 
been allowed to grow longer than 4 in. (10 cm), mow 
the lawn twice in order to reduce the grass height to 
maximum of 3-1/4 in. (8.3 cm).

4. 

Walk at a steady pace. Overlap the cutting rows. Do 
not let the grass get too tall. If the grass gets too tall, 
start at the highest cutting position and work down to 
the desired cutting height.

m

 WARNING:

 If you strike a foreign object, stop 

the motor and disconnect the power cord. Thoroughly 
inspect the mower for indication of damage. 
Thoroughly inspect the mower for any damage. If 
damaged, repair any damage before operating the 
mower. Excessive vibration of the mower during 
operation is an indication of damage. 

5.  

Please install the mulch plug when mulching.

m

 WARNING: 

Always protect your hands by wearing heavy 

gloves and/or wrapping the cutting edges with rags or other 
materials when performing any maintenance on the blades.

1. 

Release the switch lever to turn the mower OFF, wait 
for the blade to come to a complete stop, and then 
remove the battery.
