ASSEMBLY
WARNING:
• Always be sure that the lock key and battery car-
tridge are removed before carrying out any work on
the mower. Failure to remove the lock key and the bat-
tery cartridge may result in serious personal injury from
accidental start-up.
• Never start the tool unless it is completely assem-
bled. Operation of the tool in a partially assembled
state may result in serious personal injury from acci-
dental start-up.
Installing the handle (Fig. 12, 13, 14, 15, 16 & 17)
WARNING:
• When installing handles, position the wires so that they
are not caught by anything in between the handles.
1. Loosen the clamping screws (two pcs).
Expand the lower handle to its both sides and with it
expanded in that position pivot it backward and then fit it
in the groove in the deck.
2. Tighten the clamping screws on both sides to secure
the lower handle.
3. Raise the upper handle and align the screw holes in
the upper handle with those in the lower handle and
then secure it with the supplied screws and clamp-
ing nuts.
NOTE:
• At this time, keep a firm grip on the upper handle so
that it does not drop off your hand.
NOTE:
• Install the upper handle so that the direction of the
upper handle and the power supply cord are positioned
as shown in the figure.
NOTE:
• The upper handle has two holes each on both sides.
Using the different position holes for the screws and
clamping nuts allows the handle height adjustment.
Removing or installing the blade (Fig. 18 & 19)
WARNING:
• Always remove the lock key and battery cartridge when
removing or installing the blade. Failure to remove the
lock key and battery cartridge may cause a serious
injury.
• The blade coasts for a few seconds after releasing the
switch. Make sure that the blade has come to a com-
plete stop.
• Always wear gloves when handling the blade.
1. Put the mower on its side so that the mowing height
adjusting lever is placed on the upper side.
2. To lock the blade, insert a screwdriver available or
the similars in market into a hole in the mower.
3. Loosen the bolt counterclockwise with the wrench.
4. Remove the bolt, outer flange, blade and inner
flange in order.
To install the blade, take the blade removal procedure in
reverse.
WARNING:
• Install the inner flange, the blade and the outer flange
carefully as these have a top/bottom facing.
• Tighten the bolt clockwise firmly to secure the blade.
• Put the blade so that the blade side with a rotational
direction arrow faces outward.
• Make sure that the blade is installed securely.
• Always take away the screwdriver or similars inserted
in a hole to lock the blade.
Installing the grass basket (Fig. 20 & 21)
Remove the lock key.
Raise the rear guard of the mower unit and hook the
grass basket on the groove of the mower unit.
OPERATION
Mowing
WARNING:
• Before mowing, clear away sticks and stones from
mowing area. Furthermore, clear away any weeds from
mowing area in advance.
• Always wear the safety goggles or safety glasses with
side shields when operating the mower.
Firmly hold the lawn mower handle with both hands
when mowing.
The front wheel outside edges of the main unit provide a
guideline to mowing width. Using the two front wheel out-
side edges as a guideline, mow in strips, overlapping by
one half to one third the previous strip, to mow the lawn
evenly.
Periodically check the level of the grass basket, and
empty before it becomes full. Before every periodical
checks, be sure to stop the mower and remove the lock
key and the battery cartridge.
NOTE:
• Using the lawn mower with the grass basket full pre-
vents smooth blade rotation and places an extra load
on the motor, which may cause breakdown.
Mowing a long-grass lawn (Fig. 22)
Do not try to cut long grass all in one go. Instead, mow
the lawn in stages, leaving it for a day or two between
mows, until the lawn is evenly short.
NOTE:
• Mowing long grass to a short length all in one go may
cause the grass to die and/or block up the inside of the
main unit.
Emptying the grass basket (Fig. 23)
WARNING:
• To reduce a risk of accident, regularly check the grass
basket for any damage or weakened strength and
replace it if necessary.
1. Release the switch lever.
2. Remove the lock key.
3. Open the rear guard and take out the grass basket
with its handle.
4. Empty the grass basket.
