pulling the lawnmower towards you;
i) Stop the blade(s) if the lawnmower has to

be tilted for transportation when crossing

surfaces other than grass, and when

transporting the lawnmower to and from

the area to be mowed;
j) Never operate the lawnmower with

defective guards, or without safety

devices, for example deflectors and/or

grass catchers, in place;
k) Switch on the motor carefully according to

instructions and with feet well away from

the blade(s);
l) Do not tilt the lawnmower when switching

on the motor, except if the lawnmower

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 and
deliver 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 the runtime. The best
time to mow the 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 the best mulching performance, set

the cutting height to remove about one
third of the grass blade length, ideally no
more than 40mm at one time. If the lawn
is overgrown, it may be necessary to
increase the cutting 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

Cordless Lawn Mower WG770E WG770E.9

14

cut height. Otherwise, make narrower
cuts and mow slowly.

3) For the best performance, keep the
mower housing free of built-up grass.
From time to time turn off mower and
wait for the blades 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 around the blade area. Be careful
of the sharp edges of the blade. Ensure
to clean the blade area often when
cutting wet or new grass and every time
after the machine is used.

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 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.

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. 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:
(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, 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.

BLADE BALANCING (See Fig. M)

To check the balance of the blade, place
the center hole of the blade M-1 on a nail
or screwdriver shank M -2 that is securely
clamped horizontally in a vice M-3., If either
end of the blade rotates downward, file that
end. The blade is properly balanced when
neither end drops.

BLADE MAINTENANCE (See Fig. N1, N2)

Replace your metal blade after 50 hours
of use or 2 years, whichever is the sooner­regardless of the 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 (17)
counter-clockwise using a spanner wrench,
and then remove blade and fan.
To re-assemble, position the blade and fan (16)
with the cutting edges towards the ground.
Then securely tighten the blade bolt (14).

STORAGE: (See Fig. O1, O2, O3 )

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, press the Handle quick adjust
lever and fold the handle to the position.
Then the mower could stand to save space.
