Battery protection system
Lithium-ion batteries are equipped with a protection
system. This system automatically cuts off power to the
tool to extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to draw
an abnormally high current.
In this situation, release the trigger switch on the tool
and stop the application that caused the tool to become
overloaded. Then pull the trigger switch again to
restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
trigger switch again.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and recharge
the battery.
Battery remaining capacity indicator (only for
models with Battery BL3622A)
Battery BL3622A is equipped with the battery remaining
capacity indicator. (Fig. 4)
Press the CHECK button to indicate the battery
remaining capacity. The indicator lamps will then light for
approx. three seconds.

Charge the battery.
The battery may have
malfunctioned.
• When only the lowermost indicator lamp (next to the
"E") blinks, or when none of the indicator lamps light,
the battery capacity has run out, so the tool does not
operate. In these cases, charge the battery or replace
the empty battery with a fully charged one.
• When two or more indicator lamps do not light even
after charging is complete, the battery has reached the
end of its service life.
• When the upper two and lower two indicator lamps light
alternately, the battery may have malfunctioned.
Contact your local Makita authorized service center.
NOTE:
• The indicated capacity may be lower than the actual
level during use or immediately after using the tool.
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
Power switch action (Fig. 5 & 6)
WARNING:
• Before installing the battery cartridge in the tool,
always check to see that the switch lever actuates
properly and returns to the original position when
released. Operating a tool with a switch that does not
actuate properly can lead to loss of control and serious
personal injury.
NOTE:
• Trying to mow much grass at a time may not allow the
motor to start due to the overload. At this time, change
the mowing height to higher level to restart.
• The mower does not start without pressing the switch
button even if the switch lever is pulled.
This mower is equipped with the interlock switch and
handle switch. If you notice anything unusual with either
of these switches, stop operation immediately and have
them checked by your nearest Makita Authorized Service
Center.
1. Install the battery cartridge. Insert the lock key into
the interlock switch and then close the battery cover.
2. Press the switch button.
3. Pull the switch lever toward you while pressing the
switch button.
4. Release the switch button as soon as the motor
starts running. The mower will continue to run until
you release the switch lever.
5. Release the switch lever to stop the motor.
6. When not in use, remove the lock key. Store the lock
key in a safe place out of reach of children.
Adjusting the mowing height (Fig. 7)
WARNING:
• Never put your hand or leg under the mower unit when
adjusting the mowing height.
• Always make sure that the lever fits in the groove
properly before operation.
The mowing height can be adjusted in the range of
between 25 mm – 75 mm.
1. Remove the lock key.
2. Pull the mowing height adjusting lever toward A
side. Move it to your desired mowing height level.
Make sure that the pins on the mowing height
adjusting lever fit in the holes and the lever returns
to B side.
