Thin, dry
cut 8cm to
grass
4cm
* 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 the 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.
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
18 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.
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. L)
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 L-1 in a vise L-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 L-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. M)
Check balance of blade by placing center hole in blade
M-1 over a nail or screwdriver shank M -2, clamped
horizontally in a vise M-3. If either end of the blade
rotates downward, file that end. Blade is properly
balanced when neither end drops.
BLADE MAINTENANCE (See Fig. N1, N2)
Renew your metal blade after 50 hours mowing
