Switch Action - Makita HP330DZ Instruction Manual

In this situation, release the switch trigger on the tool
and stop the application that caused the tool to become
overloaded. Then pull the switch trigger again to restart.
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.

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.

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 just after the switch trigger is
released.
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.

To change the speed, switch off the tool first. Select
the "2" side for high speed or "1" for low speed but high
torque. Be sure that the speed change lever is set to the
correct position before operation.
If the tool speed is coming down extremely during the
operation with "2", slide the lever to the "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
mode marks, the tool may be damaged.

When you change the position
from " " to other modes, it may be a little dif-
ficulty to slide the action mode changing ring. In
this case, switch on and run the tool for a second
at the " " position, then stop the tool and slide
the ring to your desired position.

Adjusting the fastening torque
► Fig.7: 1. Adjusting ring 2. Graduation 3. Arrow
The fastening torque can be adjusted in 18 levels by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum fas-
tening torque at 1 and maximum torque at 18.
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.
NOTE: The fastening torque can be adjusted only
when the arrow points toward the
ring.
