Overload Protection; Overheat Protection - Makita DHP484 Manual De Instrucciones

NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off the power 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 conditions:

Overload protection

This protection works when the tool is operated in a
manner that causes it to draw an abnormally high cur-
rent. In this situation, turn the tool off and stop the appli-
cation that caused the tool to become overloaded. Then
turn the tool on to restart.

Overheat protection

This protection works when the tool or battery is over-
heated. In this situation, let the tool and battery cool
before turning the tool on again.
Overdischarge protection
This protection works when the remaining battery
capacity gets low. In this situation, remove the battery
from the tool and charge the battery.
Switch action
► Fig.3: 1. Switch trigger
CAUTION:
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.
NOTE: The tool automatically stops if you keep pull-
ing the switch trigger for about 6 minutes.
Lighting up the front lamp
► Fig.4: 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.
NOTE: When the tool is overheated, the tool stops
automatically and the lamp starts flashing. In this
case, release the switch trigger. The lamp turns off in
one minute.
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.
Reversing switch action
► Fig.5: 1. Reversing switch lever
CAUTION:
Always check the direction of
rotation before operation.
CAUTION:
Use the reversing switch only after
the tool comes to a complete stop. Changing the direc-
tion of rotation before the tool stops may damage the tool.
CAUTION:
When not operating the tool, always
set the reversing switch lever to the neutral position.
This tool has a reversing switch to change the direction of rota-
tion. Depress the reversing switch lever from the A side for clock-
wise rotation or from the B side for counterclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
Speed change
► Fig.6: 1. Speed change lever
CAUTION:
Always set the speed change lever
fully to the correct position. If you operate the tool with
the speed change lever positioned halfway between the
"1" side and "2" side, the tool may be damaged.
CAUTION:
Do not use the speed change lever
while the tool is running. The tool may be damaged.

display "2", push the lever to display "1" and restart the operation.
Selecting the action mode
CAUTION:
Always set the ring correctly to
your desired mode mark. If you operate the tool
with the ring positioned halfway between the
