FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on
the tool.
Switch action
CAUTION:
• Before plugging in the tool, always check to see
that the slide switch actuates properly and returns
to the “OFF” position when the rear of the slide
switch is depressed.
• Switch can be locked in “ON” position for ease of
operator comfort during extended use. Apply
caution when locking tool in “ON” position and
maintain firm grasp on tool.
To start the tool, slide the slide switch toward the “I (ON)”
position. For continuous operation, press the front of the
slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the “O (OFF)” position.
Speed adjusting dial
The rotating speed can be changed by turning the speed
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. And lower speed is obtained when
it is turned in the direction of number 1.
Refer to the table for the relationship between the num-
ber settings on the dial and the approximate rotating
speed.
CAUTION:
• If the tool is operated continuously at low speeds for
a long time, the motor will get overloaded and
heated up.
• The speed adjusting dial can be turned only as far
as 5 and back to 1. Do not force it past 5 or 1, or the
speed adjusting function may no longer work.
The tools equipped with electronic function are easy to
operate because of the following features.
Constant speed control
Electronic speed control for obtaining constant speed.
Possible to get fine finish, because the rotating speed is
kept constant even under load condition.
Soft start feature
Safety and soft start because of suppressed starting
shock.
