Cordless Lawn Mower   WG730E WG730E.X
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 bail handle 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 bail handle 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 
bail handle 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 BAIL HANDLE TO TURN 
MOWER “OFF” AND REMOVE SAFETY KEY WHEN 
LEAVING IT UNATTENDED EVEN FOR A SHORT 
PERIOD OF TIME.
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.
Cutting Height
Cutting Area 
(maximum)
Cutting 7 cm to 5 cm 200m

  (4.0Ah battery)
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 two fully 
charged battery packs at the same time 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.
6. MAINTENANCE
WARNING: Stop the mower, remove the safety 
key and battery before removing the grass 
collection 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 mainte-
nance, 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 AND BATTERIES ARE 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 to keep 
it balanced, removing equal amounts of material from 
both ends.
NOTE 
1. Be sure the mower is turned off . Remove the key and 
batteries. 
2. Place the mower in stand up storage mode.
TO SHARPEN BLADE IN A VISE (SEE Fig. K)
1.   Be sure the bail handle is released, the blade has 
stopped and the safety key and battery 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 your-
self.
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.
