Overload Protection; Overheat Protection - Makita HR008G Betriebsanleitung

NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
NOTE: The first (far left) indicator lamp will blink when
the battery protection system works.
Tool / 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 auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:

Overload protection

When the battery is operated in a manner that causes
it to draw an abnormally high current, the tool automat-
ically 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. In this case, let the tool and battery cool
before turning the tool on again.
NOTE: When the tool is overheated, the lamp blinks.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
Protections against other causes
Protection system is also designed for other causes
that could damage the tool and allows the tool to stop
automatically. Take all the following steps to clear the
causes, when the tool has been brought to a temporary
halt or stop in operation.
1. Turn the tool off, and then turn it on again to
restart.
2. Charge the battery(ies) or replace it/them with
recharged battery(ies).
3. Let the tool and battery(ies) cool down.
If no improvement can be found by restoring protection
system, then contact your local Makita Service Center.
Switch action
WARNING:
Before installing the battery car-
tridge into the tool, always check to see that the
switch trigger actuates properly and returns to
the "OFF" position when released.

To start the tool, simply pull the switch trigger. Tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop.
Speed change
The revolutions and blows per minute can be changed
by turning the adjusting dial to a given number setting
from 1 to 5. Higher speed is obtained when the dial
is turned in the direction of number 5. Lower speed is
obtained when the dial is turned in the direction of num-
ber 1. A target speed can be obtained when the switch
trigger is fully squeezed.

Refer to the table for the relationship between the num-
ber settings on the adjusting dial and the approximate
revolutions and blows per minute.

CAUTION:
Do not turn the adjusting dial when
the tool is running. Failure to do so may result in
the loss of control of the tool and cause an injury.
NOTICE:
If the tool is operated continuously at
low speed for a long time, the motor will get over-
loaded, resulting in tool malfunction.
NOTICE:
The adjusting dial turns between num-
ber setting 1 and 5. Avoid turning the dial back
and forwards further as it may cause damage to
the tool.
Lighting up the front lamp
► Fig.5: 1. Lamp
CAUTION:
Do not look in the light or see the
source of light directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out approximately 10 seconds after
releasing the switch trigger.
CAUTION:
If the lamp goes off after blinking
for a few seconds, the active feedback sensing
technology is not working properly. Ask your
local Makita Service Center for repair.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
NOTE: When the tool is overheated, the lamp
flashes. In this case, release the switch trigger and
then cool down the tool/battery before operating
again.
NOTE: The front lamp cannot be used while the dust
collection system (optional accessory) is installed in
the tool.
