11. Always switch off and wait for the blade to
come to a complete stop before removing the
blade from the workpiece.
12. Do not touch the blade or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
13. Do not operate the tool at no-load unneces-
sarily.
14. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material sup-
plier safety data.
15. Always use the correct dust mask/respirator
for the material and application you are work-
ing with.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated
in this instruction manual may cause serious
personal injury.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.
Selecting the cutting action (Fig. 1)
This tool can be operated with an orbital or a straight line (up and down) cutting action. The orbital cutting action
thrusts the blade forward on the cutting stroke and greatly increases cutting speed.
To change the cutting action, just turn the cutting action changing lever to the desired cutting action position.
Refer to the table to select the appropriate cutting action.
Switch action (Fig. 2)
CAUTION:
• Before plugging in the tool, always be sure that the tool
is switched off.
To start the tool, slide the switch lever to the “I” position.
To stop the tool, slide the switch lever to the “O” position.
Speed adjusting dial (Fig. 3)
For 4351CT, 4351FCT
The tool speed can be infinitely adjusted between 800
and 2,800 strokes per minute by turning the adjusting
dial. Higher speed is obtained when the dial is turned in
the direction of number 5; 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 work-
piece to be cut. However, the appropriate speed may dif-
fer 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.
CAUTION:
• 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.
