Hitachi CR13VBYNS [5/156] English

English

(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

Recommended dial scale

Mild steel pipes /

cast-iron tubes /

L-shaped angle steel

2 ― 4

Wood / wood with nails

driven in

Stainless steel 1 ― 3

Aluminum / brass /

copper

2 ― 4

Plaster board 4 ― 5

Plastic / ﬁ ber board 1 ― 3

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
