Makita DHR202 Instruction Manual page 7

• 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 over-
heated. 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.
Switch action
► Fig.3: 1. Switch trigger
CAUTION:
• Before inserting the battery cartridge 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.
Lighting up the 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 light automatically goes out 10 - 15 seconds after
the switch trigger is released.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of
lamp. Be careful not to scratch the lens of lamp,
or it may lower the illumination.
• Do not use thinner or gasoline to clean the lamp.
Such solvents may damage it.
Reversing switch action
► Fig.5: 1. Reversing switch lever
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.
CAUTION:
• Always check the direction of rotation before
operation.
• Use the reversing switch only after the tool
comes to a complete stop. Changing the direc-
tion of rotation before the tool stops may dam-
age the tool.
• When not operating the tool, always set the
reversing switch lever to the neutral position.
Selecting the action mode
Rotation with hammering
► Fig.6: 1. Rotation with hammering 2. Lock button
3. Action mode changing knob
For drilling in concrete, masonry, etc., depress the lock
button and rotate the action mode changing knob to
the symbol. Use a tungsten-carbide tipped bit.
Rotation only
► Fig.7: 1. Rotation only
For drilling in wood, metal or plastic materials, depress
the lock button and rotate the action mode changing
knob to the symbol. Use a twist drill bit or wood bit.
Hammering only
► Fig.8: 1. Hammering only
For chipping, scaling or demolition operations, depress the
lock button and rotate the action mode changing knob to
the symbol. Use a bull point, cold chisel, scaling chisel, etc.
CAUTION:
• Do not rotate the action mode changing knob when
the tool is running. The tool will be damaged.
• To avoid rapid wear on the mode change mech-
anism, be sure that the action mode changing
knob is always positively located in one of the
three action mode positions.
Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the out-
put shaft. When this happens, the bit will stop turning.
CAUTION:
• As soon as the torque limiter actuates, switch
off the tool immediately. This will help prevent
premature wear of the tool.
• Hole saws cannot be used with this tool. They
tend to pinch or catch easily in the hole. This
will cause the torque limiter to actuate too
frequently.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before carrying
out any work on the tool.
