WARNING: Be sure to identify safety measures
to protect the operator that are based on an estima-
tion of exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it is

While operating the mower, always wear sub-
stantial footwear and long trousers. Do not
operate the mower when barefoot or wearing
open sandals. Avoid wearing clothing or jewelry
that is loose tting or that has hanging cords or

7. Operate the mower only in daylight or in good
articial light.
8. Avoid operating the mower in wet grass.
9. Never operate the mower in the rain.
10. Battery tool use and care
- Recharge only with the charger specied by
the manufacturer. Achargerthatissuitablefor
one type of battery cartridge may create a risk of
rewhenusedwithanotherbatterycartridge.
- Use power tools only with specically desig-
nated battery cartridges. Use of any other bat-
terycartridgesmaycreateariskofinjuryandre.
- When battery cartridge is not in use, keep
it away from other metal objects, like paper
clips, coins, keys, nails, screws or other small
metal objects, that can make a connection
from one terminal to another. Shorting the bat-
teryterminalstogethermaycauseburnsorare.
- Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If con-
tact accidentally occurs, ush with water. If
liquid contacts eyes, additionally seek medical
help.Liquidejectedfromthebatterymaycause
irritation or burns.
11. Always keep a rm hold on the handle.
12. Always be sure of your footing on slopes.
13. Walk, never run.
14. Don't grasp the exposed cutting blades or
cutting edges when picking up or holding the
mower.

while under the inuence of drugs, alcohol, or
any medication.
16. Keep hands and feet away from rotating
blades. Caution - Blades coast after the mower
is switched off.
17. Use only the manufacturer genuine blades
specied in this manual.
18. Check the blades carefully for cracks or dam-
age before operation. Replace cracked or
damaged blades immediately.
19. Be sure the area is clear of other people before
mowing. Stop mower if anyone enters the area.
20. Remove foreign matters such as rocks, wire,
bottles, bones and large sticks from the work
area before mowing to prevent personal injury
or damage to the mower.
21. Stop operation immediately if you notice
anything unusual. Switch off the mower and
remove the key. Then inspect the mower.
22. Never attempt to make wheel height adjust-
ments while mower is running.
23. Release switch lever and wait for blade rota-
tion to stop before crossing driveways, walks,
roads, and any gravel-covered areas. Also
remove the key if you leave the mower, reach
to pick up or remove something out of your
way, or for any other reason that may distract
you from what you are doing.
24. Objects struck by the mower blade can cause
severe injuries to persons. The lawn should
always be carefully examined and cleared of
all objects prior to each mowing.
25. If the mower strikes a foreign object, follow
these steps:
- Stop the mower, release the switch lever and
wait until the blade comes to a complete stop.
- Remove the key and the battery cartridge.
- Thoroughly inspect the mower for any
damage.
- Replace the blade if it is damaged in any way.
Repair any damage before restarting and con-
tinuing to operate the mower.

the mower towards you.
28. Stop the blade(s) if the mower has to be tilted
for transportation when crossing surfaces
other than grass, and when transporting the
mower to and from the area to be used.
29. Never operate the mower with defective
guards or shields, or without safety devices,
for example deectors and/or grass basket, in
place.

4ENGLISH
30. Switch on the mower carefully according to
instructions and with feet well away from the
blade(s).
31. Do not tilt the mower when switching on the
motor, except if the mower has to be tilted for
starting. In this case, do not tilt it more than
absolutely necessary and lift only the part,
which is away from the operator.
32. Do not start the mower when standing in front
of the discharge opening.
33. Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at
all times.
34. Do not transport the mower while the mower is

MISUSE or failure to follow the safety rules stated
in this instruction manual may cause serious
personal injury.
Important safety instructions for
battery cartridge
1. Before using battery cartridge, read all instruc-
tions and cautionary markings on (1) battery char-
ger, (2) battery, and (3) product using battery.
2. Do not disassemble battery cartridge.
3. If operating time has become excessively
shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.
4. If electrolyte gets into your eyes, rinse them
out with clear water and seek medical atten-
tion right away. It may result in loss of your
eyesight.
5. Do not short the battery cartridge:
(1) Do not touch the terminals with any con-
ductive material.
(2) Avoid storing battery cartridge in a con-
tainer with other metal objects such as
nails, coins, etc.
(3) Do not expose battery cartridge to water
or rain.
A battery short can cause a large current
ow, overheating, possible burns and even a
breakdown.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50 °C (122 °F).
7. Do not incinerate the battery cartridge even if
it is severely damaged or is completely worn
out. The battery cartridge can explode in a re.
8. Be careful not to drop or strike battery.
9. Do not use a damaged battery.
10.
The contained lithium-ion batteries are subject to
the Dangerous Goods Legislation requirements.
For commercial transports e.g. by third parties,
forwardingagents,specialrequirementonpack-
aging and labeling must be observed.
For preparation of the item being shipped, consult-
inganexpertforhazardousmaterialisrequired.
Pleasealsoobservepossiblymoredetailed
national regulations.
Tapeormaskoffopencontactsandpackupthe
battery in such a manner that it cannot move
around in the packaging.
11. Follow your local regulations relating to dis-
posal of battery.
SAVE THESE INSTRUCTIONS.
CAUTION: Only use genuine Makita batteries.
Use of non-genuine Makita batteries, or batteries that
have been altered, may result in the battery bursting
causingres,personalinjuryanddamage.Itwill
also void the Makita warranty for the Makita tool and
charger.
Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice
less tool power.

5ENGLISH
2. Never recharge a fully charged battery car-
tridge. Overcharging shortens the battery
service life.
3. Charge the battery cartridge with room tem-
perature at 10 °C - 40 °C (50 °F - 104 °F). Let
a hot battery cartridge cool down before
charging it.
4. Charge the battery cartridge if you do not use
it for a long period (more than six months).

OPERATION
Mowing
WARNING: Before mowing, clear away sticks
and stones from mowing area. Furthermore, clear
away any weeds from mowing area in advance.
WARNING: 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outsideedgesofthefrontwheelsistheguideline
for mowing width. Using the two front wheel outside
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grassbasketformowedgrass.
Emptythegrassbeforeitbecomesfull.Beforeevery
periodical check, be sure to stop the mower then
remove the lock key and the battery cartridge.
NOTE: Using the mower with the grass basket full
prevents smooth blade rotation and places an extra
load on the motor, which may cause breakdown.
Mowing a long-grass lawn
Do not try to cut long grass all in one go. Instead, mow
the lawn in some steps. Leave a day or two between
mows until the lawn becomes evenly short.
NOTE: Mowing long grass to a short length all in one
gomaycausethegrasstodie.Thecutgrassmay
also block up inside of the mower body.
Emptying the grass basket
WARNING: To reduce a risk of accident, reg-
ularly check the grass basket for any damage or
weakened strength. Replace the grass basket if
necessary.
1. Release the switch lever.
2. Remove the lock key.
3. Lift the rear guard and take out the grass basket
by holding the handle.
