Adjusting the base (Fig. 5)
This unit employs a mechanism that can adjust the base
mounting position in three stages without the use of a
wrench or other tools.
(1) Press a pushbutton. When you do this, a base lever will
jump out to prepare the base for adjustment.
(2) Push up the base tip and jog the base back and forth.
(3) You can adjust the base position in three stages.
Move the base at an interval of about 15 mm, fi nd the
position where the base hooks, and press in the base
lever with your fi ngers. The base is secured when you
hear the clicking sound.
Adjusting the blade reciprocating speed
This unit has a built-in electronic control circuit that
makes it possible to adjust the variable speed of the saw
blade either both by pulling a switching trigger or turning
a dial. (Fig. 6)
(1) If you pull the trigger further in, the speed of the blade
accelerates. Begin cutting at a low speed to ensure
the accuracy of your target cut position. Once you've
obtained a suffi cient cutting depth, increase the cutting
speed.
(2) On the dial scale, "5" is the maximum speed and "1" the
minimum. The high speed is generally suitable for soft
materials such as wood, and the low speed is suitable
for hard materials such as metal. We recommend that
you use the following as a rough guide in selecting the
suitable speed for the materials you are cutting.
Example of materials to
be cut
Mild steel pipes /
cast-iron tubes /
L-shaped angle steel
Wood / wood with nails
driven in
Stainless steel
Aluminum / brass /
copper
Plaster board
Plastic / fi ber board

CAUTION
○ When cutting at low speed (scale of 1 – 2), never cut a
wooden board more than 10 mm thick or a mild steel
plate more than 2 mm thick. The load on the motor can
result in overheating and damage.
○ Although this unit employs a powerful motor, prolonged
use at a low speed will increase the load unduly and
may lead to overheating. Properly adjust the saw blade
to allow steady, smooth cutting operation, avoiding any
unreasonable use such as sudden stops during cutting
operation.
SELECTION OF BLADES
To ensure maximum operating effi ciency and results, it is
very important to select the appropriate blade best suited to
the type and thickness of the material to be cut.
NOTE
Dimensions of the workpiece mentioned in the table
represent the dimensions when the mounting position of
the base is set nearest to the body of the reciprocating
saw. Caution must be exercised since dimensions of the
workpiece will become smaller if the base is mounted far
away from the body of the reciprocating saw.
1. Selection of HCS blades
The blade number of HCS blades in Table 1 is engraved
in the vicinity of the mounting position of each blade.
Select appropriate blades by referring to Tables 1 and
4 below.
