How to make the batteries perform longer

(1) Recharge the batteries before they become

completely exhausted.

When you feel that the power of the tool becomes

weaker, stop using the tool and recharge its battery.

If you continue to use the tool and exhaust the

electric current, the battery may be damaged and

its life will become shorter.

(2) Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after

use. If such a battery is recharged immediately after

use, its internal chemical substance will deteriorate,

and the battery life will be shortened. Leave the

battery and recharge it after it has cooled for a

while.

PRIOR TO OPERATION

1. Mounting the blade

This unit employs a detachable mechanism that

enables mounting and removal of saw blades

without the use of a wrench or other tools.

(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

remove the battery (Fig. 6).

CAUTION

Be absolutely sure to keep the switch turned off

and the battery removed to prevent any accident.

(2) Push the lever in the direction of the arrow mark

shown in Fig. 7 marked on the lever (Fig. 7).

(3) Insert the saw blade all the way into the small slit

of the plunger tip with the lever pushing. You can

mount this blade either in the upward or downward

direction (Fig. 8, Fig. 9).

(4) When you release the lever, the spring force will

return the lever to the correct position automatically

(Fig. 10).

(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. 11).

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.

2. 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

remove the battery (Fig. 6).

CAUTION

Be absolutely sure to keep the switch turned off

and the battery removed to prevent any accident.

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

of the arrow mark shown in Fig. 7 and secured it,

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. 12).

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. 13, 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. 14 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. 15).

3. Moving the base

Loosen the set screw and move the base forward,

as shown in Fig. 16, Fig. 17. Tighten the set screw

slightly, ensure the base does not move back and

forth, and firmly tighten the set screw. Ensure that

the base does not contact the blade.

4. Confirm that the battery is mounted correctly

HOW TO USE

CAUTION

⅜ Do not carry tools 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 (refer to Fig. 6).
