Mowing Tips

m
WARNING!
Inspect the area prior to mowing/mulching
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 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.
• Verify that the lawn is free of stone, sticks, wires, and other
foreign objects that could damage the blade or the motor.
These objects could accidentally be picked up and thrown
by the mower in any direction, which could lead to serious
personal 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 a circle. Travel back and forth across the
lawn following the path outlined below (Fig. 11).
• 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.

7. 2.87 in. (73 mm)
• 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 mower. The stones can be picked up
and thrown by the rotating blade.
• Set the 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 mower
for any damage. Repair any damage before operating the
mower.

Mulching Tips

m
WARNING!
Inspect the area prior to mowing/mulching
and remove all the stones, sticks, wires, and other debris that
might be thrown by the rotating blade.
• The unit is sent in mulching mower mode with the mulch
plug being assembled already. If you have used the unit
as a lawn mower and want to convert your lawn mower to
a mulching mower, lift up the grass collection bag cover
and remove the grass collection bag. Insert the mulch plug
(Fig. 12) and close the grass collection bag cover.

• For effective mulching, do not cut wet grass because 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 to the maximum of 3¼ in. (8.3 cm).
• Walk at a steady pace. Overlap the cutting rows. Do not
let the grass get too tall. If the grass gets too long, start at
the highest cutting position and work down to the desired
cutting height.
