Speed adjusting dial
For model 3612C only
003802
The tool speed can be changed by turning the speed adjust-
ing dial to a given number setting from 1 to 5.
Higher speed is obtained when the dial is turned in the direc-
tion of number 5. And lower speed is obtained when it is
turned in the direction of number 1.
This allows the ideal speed to be selected for optimum mate-
rial processing, i.e. the speed can be correctly adjusted to
suit the material and bit diameter.
Refer to the table for the relationship between the number
RPM
settings on the dial and the approximate tool speed.

• If the tool is operated continuously at low speeds for a
23,000
long time, the motor will get overloaded, resulting in tool
malfunction.
• 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.
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.

Installing or removing the bit

003670
CAUTION:
• Install the bit securely. Always use only the wrench
provided with the tool. A loose or overtightened bit can
be dangerous.
• Do not tighten the collet nut without inserting a bit or
install small shank bits without using a collet sleeve.
Either can lead to breakage of the collet cone.
Insert the bit all the way into the collet cone. Press the shaft
lock to keep the shaft stationary and use the wrench to
tighten the collet nut securely. When using router bits with
smaller shank diameter, first insert the appropriate collet
sleeve into the collet cone, then install the bit as described
above.
To remove the bit, follow the installation procedure in reverse.
