Worx WG771 Mode D'emploi page 17

the cutting height to remove about one
third of the grass blade length, ideally
no more than 1.5" inches 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.
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(6) 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 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 Collection Bag.
Note: To ensure long and reliable service,

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 1-866-354-

3-in-1 Cordless Lawn Mower
BLADE (18) 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. M)
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.
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. 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)
Replace your metal Blade (18) 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
and unscrew the Blade Bolt (17) counter-
clockwise using a spanner wrench, and then
remove the Blade.
To re-assemble, position the Blade with the
cutting edges towards the ground. Then
securely tighten the Blade Bolt.
