MULCHING MOWING TIPS
When in mulch mode, your new mower is designed
to cut the grass clippings into small pieces and
distribute them back into the lawn, using mulching
ns located inside the mower deck.
Under normal conditions, the mulched grass will
biodegrade quickly to provide nutrients to the lawn.
Please review the following recommendations for
optimum mulching performance,
1) Avoid mowing when the grass is wet from rain
or dew. Wet grass may form clumps which
interfere with the mulching action and reduce
runtime. The best time to mow grass is in the
late afternoon when the grass is dry and the
newly cut area will not be exposed to direct
sunlight.
2) For best mulching performance, set the cutting
height to remove about one third of the grass
blade length, ideally no more than 1.5” at
one time. If the lawn is overgrown, it may be
necessary to increase the cut height to reduce
the pushing effort and prevent overloading the
motor. The side-discharge chute can also be
used to evacuate excessively grown grass and
minimize overloading the motor. For extremely
heavy mulching, it is advisable to rst cut at a
high cut height setting, and then re-cut to the
nal cut height. Otherwise, make narrower cuts
and mow slowly.
3) For best performance, keep the mower deck free
of built-up grass. From time to time turn mower
off, remove batteries and wait for the blade to
come to a complete stop. Turn mower on its
side. Using an object such as a stick, wipe out
any accumulation of grass in the blade area. Be
careful of the sharp edges of the blade. Clean
often in wet, new grass, and always after every
use.
4) Certain types of grass or grass conditions may
require that an area be mulched a second time
to fully disperse the grass throughout the lawn.
If cutting a second time, it is advisable to cut
perpendicular (across) the rst cut pattern.
DO NOT CHANGE CUT PATTERN IN ANY WAY
THAT WOULD CAUSE MOWING DOWN A HILL.
5) Change your cutting pattern from week to week.
This will help prevent matting and graining of
the lawn.
CUTTING AREA
The cutting area can be affected by many factors
including: cutting height, operation practices (ex:
starting/stopping), lawn moisture levels, grass
length and thi ckness.
It is ideal for mowing ¼ acre to
1
/2 acre lot sizes.
TIPS:
1) Mowing the lawn frequently and reducing the
15
2x20V 21inch Cordless Brush-
less Self-Propelled Lawn Mower
EN
amount of starting/stopping procedures will help
conserve battery runtime. It is recommended to
always use the same two batteries during operation
with fully charged levels.
2) For the best cutting performance, it is
recommended to only mow up to 1/3 or less of the
current grass height at a time. Mow at a slower
pace when cutting long/thick grass to allow the
mower time to cut and to properly discharge the
clippings.
6. MAINTENANCE
WARNING: Stop the mower and remove
batteriesbefore removing the grass
collection bag.
NOTE: To ensure long and reliable service,
perform the following maintenance procedures
regularly. Check for obvious defects such as a
loose, dislodged or a damaged blade, loose ttings,
and worn or damaged components. Check that
the covers and guards are all undamaged and
are correctly attached to mower. Carry out any
necessary maintenance or repairs before operating
mower. If the mower should happen to fail despite
regular maintenance, please call our customer
helpline for advice.
BLADE SHARPENING
KEEP BLADE SHARP FOR BEST MOWER
PERFORMANCE. A DULL BLADE DOES NOT CUT
GRASS CLEANLY OR MULCH PROPERLY.
WEAR PROPER EYE PROTECTION WHILE
REMOVING, SHARPENING, AND INSTALLING
BLADE. ENSURE THE BATTERIES ARE REMOVED.
Sharpening the blade twice during a mowing
season is usually sucient under normal
circumstances. Sand causes the blade to dull
quickly. If your lawn has sandy soil, more frequent
sharpening may be required.
REPLACE BENT OR DAMAGED BLADE
IMMEDIATELY.
WHEN SHARPENING THE BLADE (See Fig. L)
1. Make sure blade remains balanced.
2. Sharpen blade at the original cutting angle.
3. Sharpen cutting edges on both ends of blade to
keep it balanced, removing equal amounts of
material from both ends.
NOTE:
1. Be sure the mower is turned off and remove
batteries
2. Place the mower in stand up storage mode.
BLADE BALANCING (See Fig. M)
Check balance of blade by placing center hole in
blade M-1 over a screwdriver shank M-2, clamped
horizontally in a vise M-3. If either end of the blade
rotates downward, le that end. Blade is properly
balanced when neither end drops.
BLADE MAINTENANCE (See Fig. N1, N2)
Replace your Mower Blade after 50 hours of
mowing or 2 years of use, whichever comes rst.
Follow these procedures to remove and replace the
Blade. You will need garden gloves (not provided)
and a spanner wrench (not provided) to remove the
Blade. Make sure batteries are not installed. Wedge
a block of wood between the blade and the mower
deck to prevent the blade from turning and unscrew
the Blade Bolt counter-clockwise using a spanner
wrench, and then remove the Blade.
To re-assemble, position the Blade with the cutting
edges towards the ground. Then securely tighten
the Blade Bolt.
7. STORAGE (SEE FIG. K1,
K2)
Stop the mower and remove batteries. Clean the
exterior of the machine thoroughly using a soft
brush and cloth. Do not use water, solvents or
polishes. Remove all grass and debris, especially
from the ventilation slots.
Turn the machine on its side and clean the blade
area. If grass cuttings are compacted in the blade
area, remove with a wooden or plastic implement.
Store the machine in a dry place. Do not place other
objects on top of the machine.
To aid storage, pinch the Quick-release button and
pull it out, and then rotate the Quick-release button,
and fold the Handle bar. The mower can also be
stored in a vertical orientation to conserve space
(g. K2).
NOTE: After the Handle bar is folded, the Quick-
release button needs to be screwed back into place.
