Operation - Makita DF330DSP1A Instruction Manual

Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. If you pull the switch trigger, the motor
runs again but stops soon. In this situation, remove and
recharge the battery.
Switch action
► Fig.2: 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.
Lighting up the front lamp
► Fig.3: 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: Use a dry cloth to wipe the dirt off the lens
of the lamp. Be careful not to scratch the lens of the
lamp, or it may lower the illumination.
Reversing switch action
► Fig.4: 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
direction of rotation before the tool stops may dam-
age the tool.
CAUTION:
When not operating the tool,
always set the reversing switch lever to the neu-
tral position.
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for coun-
terclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
Speed change
► Fig.5: 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.

operation with "2", slide the lever to the "1" and restart
the operation.
Adjusting the fastening torque
► Fig.6: 1. Adjusting ring 2. Graduation 3. Arrow
The fastening torque can be adjusted in 19 levels by

tening torque at 1 and maximum torque at
The clutch will slip at various torque levels when set
at the number 1 to 18. The clutch does not work at
the marking.
Before actual operation, drive a trial screw into your
material or a piece of duplicate material to deter-
mine which torque level is required for a particular
application.
