(5) Pull the back of the saw blade two or three times

by hand and check that the blade is securely

mounted. When pulling the blade, you will know

it is properly mounted if it clicks and the lever

moves slightly. (Fig. 6)

CAUTION

When pulling the saw blade, be absolutely sure to

pull it from the back. Pulling other parts of the blade

will result in an injury.

6. Dismounting the blade

(1) Turn on and off the switching trigger several times

so that the lever can jump out of the front cover

completely. Thereafter, turn off the switch and

unplug the power cord. (Fig. 1)

CAUTION

Be absolutely sure to keep the switch turned off

and the power cord unplugged to prevent any

accident.

(2) After you have pushed the lever in the direction

of the arrow mark shown in Fig. 2, turn the blade

so it faces downward. The blade should fall out by

itself. If the blade doesn’t fall out, pull it out by

hand.

CAUTION

Never touch the saw blade immediately after use.

The metal is hot and can easily burn your skin.

WHEN THE BLADE IS BROKEN

Even when the saw blade is broken and remains

inside the small slit of the plunger, it should fall

out if you push the lever in the direction of the

arrow mark, and face the blade downward. If it

doesn’t fall out itself, take it out using the procedures

explained below.

(1) If a part of the broken saw blade is sticking out

of the small slit of the plunger, pull out the protruding

part and take the blade out.

(2) If the broken saw blade is hidden inside the small

slit, hook the broken blade using a tip of another

saw blade and take it out. (Fig. 7)

MAINTENANCE AND INSPECTION OF SAW BLADE

MOUNT

(1) After use, blow away sawdust, earth, sand, moisture,

etc., with air or brush them away with a brush, etc.,

to ensure that the blade mount can function

smoothly.

(2) As shown in Fig. 8, carry out lubrication around the

blade holder on a periodic basis by use of cutting

fluid, etc.

NOTE:

Continued use of the tool without cleaning and

lubricating the area where the saw blade is installed

can result in some slack movement of the lever due

to accumulated sawdust and chips. Under the

circumstances, pull a rubber cap provided on the

lever in the direction of an arrow mark as shown

in Fig. 9 and remove the rubber cap from the lever.

Then, clean up the inside of the blade holder with

air and the like and carry out sufficient lubrication.

The rubber cap can be fitted on if it is pressed firmly

onto the lever. At this time, make certain that there

exists no clearance between the blade holder and

the rubber cap, and furthermore ensure that the

saw-blade-installed area can function smoothly.

CAUTION:

Do not use any saw blade with a worn-out blade

hole. Otherwise, the saw blade can come off,

resulting in personal injury. (Fig. 10)

7. Adjusting the base

(1) Lift the front cover up as illustrated in Fig. 11.

(2) If a base setting screw is loosened with an attached

hexagonal bar wrench, you can adjust a base

installing position. (Fig. 12, Fig. 13)

(3) After adjusting the base installing position, tighten

the base setting screw with the attached hexagonal

bar wrench completely.

8. 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 by pulling a switching trigger. (Fig.

14)

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 sufficient cutting depth,

increase the cutting speed.

CAUTION

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.

HOW TO USE

CAUTION

⅜ Avoid carrying it plugged to the outlet with your

finger on the switch. A sudden startup can result

in an unexpected injury.

⅜ Be careful not to let sawdust, earth, moisture, etc.,

enter the inside of the machine through the plunger

section during operation. If sawdust and the like

accumulate in the plunger section, always clean it

before use.

⅜ Do not remove the front cover (refer to Fig. 1).

Be sure to hold the body from the top of the front

cover.

⅜ During use, press the base against the material

while cutting.

Vibration can damage the saw blade if the base is

not pressed firmly against the workpiece.

Furthermore, a tip of the saw blade can sometimes

contact the inner wall of the pipe, damaging the

saw blade.

⅜ Select a saw blade of the most appropriate length.

Ideally, the length protruding from the base of the

saw blade after subtracting the stroke quantity should

be larger than the material (see Fig. 15 and

Fig. 17).

If you cut a large pipe, large block of wood, etc.,

that exceeds the cutting capacity of a blade; there

is a risk that the blade may contact with the inner

wall of the pipe, wood, etc., resulting in damage.

(Fig. 16, Fig. 18)

1. Cutting metallic materials

CAUTION

⅜ Press the base firmly against the workpiece.

⅜ Never apply any unreasonable force to the saw

blade when cutting. Doing so can easily break the

blade.
