8. MOWING TIPS
NOTE: Always inspect area where mower
is to be used and remove all stones,
sticks, wire, metal and other debris
which might be thrown by the rotating
blade.
1) Mow across the face of slopes, never up-
and-down. Exercise extreme caution when
changing direction on slopes. Do not mow
excessively steep slopes. Always maintain
good footing.
2) Release switch lever to turn mower “OFF”
when crossing any graveled area (stones
can be thrown by the blade).
3) Set mower at highest cutting height when
mowing in rough ground or in tall weeds.
Removing too much grass at one time can
cause circuit breaker to trip, which stops
mower.
4) If a grass bag is used during the fast
growing season, the grass may tend to clog
up at the discharge opening. Release switch
lever to turn mower “OFF” and remove
the safety key. Remove the grass bag and
shake the grass down to the back end of
the bag. Also clean out any grass or debris
which may be packed around the discharge
opening. Replace the grass bag.
5) If mower should start to vibrate abnormally,
release switch lever to turn mower “OFF”
and remove safety key. Check immediately
for cause. Vibration is a warning of trouble.
Do not operate mower until a service check
has been made.
6) ALWAYS RELEASE SWITCH LEVERTO
TURN MOWER “OFF” AND REMOVE
SAFETY KEY WHEN LEAVING IT
UNATTENDED EVEN FOR A SHORT PERIOD
OFTIME.
9. MULCHING MOWING TIPS
While mulching, your new mower is designed
to cut the grass clippings into small pieces
and distribute them back into the lawn. 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 inch 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. For
extremely heavy mulching, it is advisable
to first cut at a high cut height setting,
and then re-cut to the final cut height.
Otherwise, make narrower cuts and mow
slowly.
NOTE:The motor is protected by a safety
cut out which is activated when the
blade becomes jammed or if the motor
is overloaded. The safety cut out will
only reset when the switch lever 2 is
released. Clear any obstruction and
wait for a few minutes for the safety
cut out to reset before continuing to
use the mower. At this time do not
operate the switch lever 2 as this will
prolong the reset time of the safety
cut out. If the mower cuts out again
increase the height of cut to reduce
the load on the motor.
3) For best performance, keep the mower
housing free of built-up grass. From time to
time turn off mower and wait for the blade
to come to a complete stop.Then unplug
the safety key and 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 first cut
pattern. DO NOT CHANGE CUT PATTERN

1716
Cordless self-propelled lawn mower
EN
1716
IN ANY WAYTHAT 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.
MAINTENANCE
WARNING: Stop the mower and
remove the safety key before
removing the grass 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 fittings, 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. ENSURETHAT SAFETY KEY IS
REMOVED.
Sharpening the blade twice during a mowing
season is usually sufficient 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:
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.
TO SHARPEN BLADE IN A VISE (See O)
1. Be sure the switch lever is released, the
blade has stopped and the safety key
removed before removing the blade.
2. Remove blade from mower. See
instructions for removing and attaching
blade.
3. Secure blade O-1 in a vise O-2.
4. Wear safety glasses and be careful not to

replace the blade. You will need garden
gloves (not provided) and a spanner wrench
(not provided) to remove the blade. Hold the
blade (R-2) and unscrew the blade nut (R-5)
counterclockwise using a spanner wrench.
Remove blade nut (R-5), square washer (R-4),
insulator washer (R-3), and blade (R-2).
To re-assemble, first position the blade
with the cutting edges towards the ground.
Assemble the components.
Ensure that the edges of the insulator washer
hook over the edge of the blade. Align the flats
on the square washer (R-4) with the flats on
the shaft.
Then securely tighten the blade nut.
