Speed adjusting dial
CAUTION:
The speed adjusting dial is not for
using low speed rated blades but for obtaining a
speed which is suitable to material of workpiece.
Use only blades which are rated for at least the maxi
-
mum no load speed stated in the SPECIFICATIONS.
CAUTION:
The speed adjusting dial can be
turned only as far as 6 and back to 1.
Do not force it
past 6 or 1, or the speed adjusting function may
no longer work.
The tool speed can be adjusted by turning the adjusting
dial. Higher speed is obtained when the dial is turned in
the direction of number 6; lower speed is obtained when
it is turned in the direction of number 1.
Refer to the table to select the proper speed for the
workpiece to be cut. However, the appropriate speed
may differ with the type or thickness of the workpiece. In
general, higher speeds will allow you to cut workpieces
faster but the service life of the blade will be reduced.

1.
Set the guide plate onto the guide rail near from
the cutting start point. The plate edge represents the
center of the groove cutter blade. Align the plate edge
with the cutting line.

Then, set again the guide plate on the guide rail
near the cutting end point. And align the plate edge with
the cutting line again.
Other features
The tools equipped with electronic function are easy to
operate because of the following features.
Overload protector
When the load on the tool exceeds admissible levels,
power to the motor is reduced to protect the motor from
overheating. When the load returns to admissible lev-
els, the tool will operate as normal.
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
Soft start because of suppressed starting shock.
