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 check to see 
that the switch trigger actuates properly and returns 
to the "OFF" position when released. 
• 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, simply pull the switch trigger. Release 
the switch trigger to stop. 
For continuous operation, pull the switch trigger and then 
push in the lock button. 
To stop the tool from the locked position, pull the switch 
trigger fully, then release it. 
Speed adjusting dial 
Fig.3 
The tool speed can be infinitely adjusted by turning the 
speed adjusting dial. Higher speed is obtained when the 
speed adjusting 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 
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. 
Number on adjusting dial
4 - 5
Mildsteel 3 - 5
Stainless steel 3 - 4
Aluminum 3 - 5
Plastics 1 - 4

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. 
ASSEMBLY 
 
CAUTION: 
• 
Always be sure that the tool is switched off and 
unplugged before carrying out any work on the tool. 
Installing or removing saw blade 
 
CAUTION: 
• Always clean out all chips or foreign matter 
adhering to the blade and/or blade holder. Failure 
to do so may cause insufficient tightening of the 
blade, resulting in a serious personal injury. 
• Do not touch the blade or the workpiece 
immediately after operation; they may be extremely 
hot and could burn your skin. 
• Use only B type blades. Using blades other than B 
type blades causes insufficient tightening of the 
blade, resulting in a serious personal injury. 
• When you remove the saw blade, be careful not to 
hurt your fingers with the top of the blade or the tips 
of workpiece.

Before installing the blade, make sure that the blade 
clamp lever is in the released position. 
To install the blade, insert the blade (teeth facing forward) 
into the blade holder until it latches. The lever moves to 
the fixed position by itself and the blade is locked. Pull 
the blade lightly to make sure that the blade does not fall 
off during operation. 
 
CAUTION: 
• If the lever does not move to the fixed position by 
itself, the blade is not installed completely. Do not 
press the lever by hand to the fixed position. It may 
damage the tool. Make sure that the back edge of 
the blade fits into the roller. 
To remove the blade, push the lever forward as far as it 
will go. This allows the blade to be released.
