Battery protection system

The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life.
The tool will automatically stop during operation if the
tool or battery is placed under one of the following con-
ditions. In some conditions, the indicators light up.
Overload protection
When the tool is operated in a manner that causes it to
draw an abnormally high current, the tool automatically
stops without any indication. In this situation, turn the
tool off and stop the application that caused the tool to
become overloaded. Then turn the tool on to restart.
Overheat protection
When the tool or battery is overheated, the tool stops
automatically without any indications. The tool does not
start even if turning on the tool. In this situation, let the
tool or battery cool before turning the tool on again.
NOTE: The battery overheat protection works only
with a battery cartridge with a star marking. The tool
overheat protection system works with any battery
cartridges.

lights up about 10 seconds. In this situation, charge the
battery cartridge.

Power switch action
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 cartridges. Insert the lock key
into the interlock switch and then close the battery
cover.
