VIBRATION INFORMATION
Typical weighted vibration ah=xx m/s2
uncertainty K=1.5m/s²
WARNING:The vibration emission value during actual use of the power tool can differ from the
declared value depending on the ways in which the tool is used dependant on the following examples
and other variations on how the tool is used:
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained
Using the correct accessory for the tool and ensuring it is sharp and in good condition.
The tightness of the grip on the handles and if any anti vibration accessories are used.
And the tool is being used as intended by its design and these instructions.
This tool may cause hand-arm vibration syndrome if its use is not adequately managed
WARNING: To be accurate, an estimation of exposure level in the actual conditions of use should also
take account of all parts of the operating cycle such as the times when the tool is switched off and when
it is running idle but not actually doing the job.This may significantly reduce the exposure level over the total
working period.
Helping to minimise your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades
Maintain this tool in accordance with these instructions and keep well lubricated (where appropriate)
If the tool is to be used regularly then invest in anti vibration accessories.
Plan your work schedule to spread any high vibration tool use across a number of days.

CUTTING AREA
The cutting area can be affected by several factors,
such as cutting height, lawn humidity, grass length
and density. Besides, starting and stopping the mower
too many times during operation will reduce the
cutting area.
The table below gives the relationship between cutting
conditions and cutting area.

Thin, dry
grass cut 8cm
to 4cm 140m2*230m2*11 5 m 2*
* Used with two fully charged battery packs.
TIPS:
1) It is recommended to mow your lawn more
frequently, walk at normal pace, and not to start/
stop the mower too often during operation. Please
always use the same two batteries and charge the
two batteries at same time.
2) For best performance, please ensure use a fully
charged battery pack and always cut off 1/3 or less
of the grass height.
3) Walk slowly when cutting long grass, so as to have
more effective cutting and properly discharge the
clippings.
4) Avoid cutting wet grass, otherwise it will stick to
the underside of the deck and the clippings cannot
be collected or discharged properly.
5) A higher cutting height shall be applied to new or
thick grass and it will extend the battery duration.
BATTERY STATUS (See Fig. F)
Before starting or after use, press the button
“POWERTEST” on the machine to check the battery
capacity. During operation, the battery capacity will be
indicated automatically by the battery power indicator.
The indicator constantly senses and displays the
battery condition as follows:
Battery power

Five green lights
() are
illuminated.
The two batteries are in a
highly charged condition.
Two, three or four
green lights are
illuminated.
The two batteries have a
remaining charge.The more
lights are illuminated, the
more battery capacity.
Only one green
light ( )
is illuminated.
At least one battery is deplet-
ed and needs to be charged.
No light is
illuminated.
At least one battery is not
fully installed or battery is
defective.
Only one light
() is
flashing twice per
cycle.
At least one battery is over
discharged, please recharge
the two batteries at once be-
fore use again or storage.
Only one light
() is
flashing three
times per cycle.
At least one battery is hot,
wait for them cool down
before start again.
Only one light
() is
flashing four
times per cycle.
The machine is over load.
Raise the cutting height or
push slowly.
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 collection 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.

19
Cordless Lawn Mower EN
6. ALWAYS RELEASE SWITCH LEVER TO TURN
MOWER “OFF” AND REMOVE SAFETY KEY
WHEN LEAVING IT UNATTENDED EVEN FOR
A SHORT PERIOD OF TIME.
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.
WEAR PROPER EYE PROTECTION WHILE REMOVING,
SHARPENING, AND INSTALLING BLADE. ENSURE
THAT 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,
removing equal amounts of material from both
ends.
Note: 1. Be sure the mower is turned off and remove
the key.
2. Place the mower in stand up storage mode.
TO SHARPEN BLADE IN A VISE (SEE Fig. M)
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 M-1 in a vise M-2.
4. Wear safety glasses and be careful not to cut
yourself.
5. Carefully file the cutting edges of the blade with a
fine tooth file M-3 or sharpening stone.
6. Check balance of blade. See instructions for blade
balancing.
7. Replace blade on mower and tighten securely.
Refer to instructions below.
BLADE BALANCING (SEE Fig. N)
Check balance of blade by placing center hole in blade
N-1 over a nail or screwdriver shank N-2, clamped
horizontally in a vise N-3. If either end of the blade
rotates downward, file that end. Blade is properly
balanced when neither end drops.
BLADE MAINTENANCE (See Fig. O1, O2)
Renew your metal blade after 50 hours mowing or 2
years, whichever is the sooner-regardless of condition.
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.
Hold the blade (16) and unscrew the blade bolt (15)
counter-clockwise using a spanner wrench, and then
remove blade.
To re-assemble, position the blade (16) with the
cutting edges towards the ground.Then securely
tighten the blade bolt (15).
STORAGE (See Fig. L1, L2)
Stop the mower and always remove the safety key.
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, release the handle knob, and fold the
upper handle as shown in Fig. L1 & L2.
ENVIRONMENTAL
PROTECTION
