Status1: QUIET mode

Select QUIET mode when mowing in everyday
conditions, removing approximately 20mm of grass at
a time.

Status2: TURBO mode

Set the dial to TURBO mode when cutting dense or
overgrown grass.

3. BATTERY STATUS LED’S (See Fig. G)
NOTE: The Status LED’s will indicate the battery
condition when the button on the battery is
pressed.

The LED’s constantly senses and displays the battery
condition as follows:
Press the button “POWERTEST”, the light button is
illuminated.
When the three green lights are illuminated, the battery
is in a highly charged condition.
When two lights ( ) are illuminated, the battery is
in a moderately charged condition.
When only one green light ( ) is illuminated, the
battery charge is depleted.
Before using your new mower for the first time, it is
recommended that the unit be charged overnight to
ensure that the battery is fully charged.

IMPORTANT
When only one light is illuminated, your battery
is overly discharged, even though the mower
may still be capable of cutting grass. Continuing
to operate your lawnmower with the battery in
this discharged condition may reduce the life and
performance of your battery.

4. ADJUSTING THE CUTTING HEIGHT (See Fig. H)

WARNING! Stop, release switch lever and wait

until the motor stops before adjusting height. The
blades continue to rotate after the machine is switched
off, a rotating blade can cause injury.

CAUTION: Do not touch rotating blades.

For the first cutting of the season, a high cutting
adjustment should be selected. The lawnmower can be
set to 5 cutting heights between 20mm and 60mm. For

can follow as below:

M2

Empty status: flap floats (a)

Fully status: flap falls down (b)

6. REAR DISCHARGE (See Fig. J)

The mower provides a rear discharge function, so that
you can mower without bag collection. The debris will
be discharged from the rear chute.

7. 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.

14

Cutting Conditions

Grass Conditions Cutting Height

Very thin, dry
grass

Thin, dry grass cut 8cm to 4cm 150m2 *

* Used with a fully charged battery pack

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.

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 can not 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.

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

cut 6cm to 4cm

Cutting Area

(maximum)

Cordless Lawn Mower WG776E WG776E.9

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.

6. ALWAYS RELEASE SWITCH LEVER TO TURN
MOWER “OFF” AND REMOVE SAFETY KEY
WHEN LEAVING IT UNATTENDED EVEN FOR A
SHORT PERIOD OF TIME.

15

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

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.

TO SHARPEN BLADE IN A VISE
(See Fig. K)

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 K-1 in a vise K-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 K-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. L)

Check balance of blade by placing center hole in blade
L-1 over a nail or screwdriver shank L -2, clamped
horizontally in a vise L-3. If either
end of the blade rotates downward, file that end. Blade
is properly balanced when neither end drops.

BLADE MAINTENANCE (See Fig. M1,M2)

Renew your metal blade after 50 hours mowing or 2
years, which ever 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 (15) and unscrew the blade bolt (14)
counter-clockwise using a spanner wrench, and then
remove blade.
To re-assemble, position the blade (15) with the cutting
edges towards the ground. Then securely tighten the
blade bolt (14).
