CAUTIONS

⅜ Before starting to saw, ensure that the saw blade

has reached full speed revolution.

⅜ Should the saw blade be stopped or made an

abnormal noise during operation, turn off the switch

immediately.

⅜ When finished with a job, pull out the battery from

the main body.

⅜ Twisting and forcibly pressing the saw during cutting

can result in unreasonable pressure on the motor,

so try to go straight quietly.

⅜ In the situation where the circular saw is continuously

operated while replacing the battery with stocked

spare batteries one after another, the motor tends

to overheat. Therefore, whenever the housing

becomes hot, give the saw a break for a while.

⅜ Avoid cutting operation in a state where the base

bottom is afloat from the material being cut.

Otherwise, the motor can get locked.

MOUNTING AND DISMOUNTING THE SAW

BLADE

CAUTION

To avoid serious accident, ensure the switch is in

the OFF position, and pull out the battery.

1. Dismounting the saw blade

(1) Set the cutting volume at maximum, and place the

Circular Saw as shown in Fig. 19.

(2) Depress the lock lever, lock the spindle, and remove

the hexagonal-head bolt and washer (B) with the

box wrench.

(3) While holding the safety cover lever to keep the

safety cover fully retracted into the saw cover,

remove the saw blade. (Fig. 20)

2. Mounting the Saw Blade:

CAUTION:

If the bolt is worked using other tools than the

provided box wrench, excessive tightening and

insufficient tightening may take place resulting in

injury.

(1) Thoroughly remove any sawdust which has

accumulated on the spindle, bolt and washers.

(2) As shown in Fig. 21, the side of Washer (A) with

a projected center the same diameter as the inner

diameter of the saw blade and the concave side

of Washer (B) must be fitted to the saw blade sides.

* Washer (A) is supplied for 2 types of saw blades

with the hole diameters of 16 mm and 30 mm.

(When buying the Circular Saw, one type of

washer (A) is spplied.)

In case the hole diameter of your saw blade

does not correspond to that of washer (A), please

contact the shop where you purchased the

Circular Saw.

(3) To assure proper rotation direction of the saw blade,

the arrow direction on the saw blade must coincide

with the arrow direction on the saw cover.

(4) Using the fingers, tighten the hexagonal-head bolt

retaining the saw blade as much as possible. Then

depress the lock lever, lock the spindle, and

thoroughly tighten the hexagonal-head bolt.

CAUTION

After having attached the saw blade, reconfirm that

the lock lever is firmly secured in the prescribed

position.

REPLACING LIGHT BULB

CAUTION:

⅜ Make absolutely sure that the battery is removed

from the main body before replacing the light bulb.

⅜ Immediately after the light is turned OFF, the bulb

retains high temperature. Make sure to cool down

the light bulb thoroughly before replacing it so as

to prevent burns.

⅜ When replacing the light bulb, check the shape of

base as well as the rating (12 V, 5 W), and then

carry out perfect mounting. Otherwise, the light

bulb can come off and/or cause overheat.

1. Detaching light bulb

(1) Remove the convex part of the light cover from the

concave part of the handle cover, and then pull out

the light cover in the arrow-marked direction as

shown in Fig. 22.

(2) Push the back of the socket, and remove the socket

and the light bulb together from the handle cover

(Fig. 23).

(3) Remove the light bulb from the socket. (Fig. 24).

2. Attaching light bulb

Take procedures here that are contrary to the

detaching procedures.

NOTE:

⅜ When attaching the light bulb to the socket, insert

the light bulb until it lightly bumps against the

socket.

⅜ When attaching the socket to the handle cover,

align the socket with the hole of housing while

watching the back of the socket shown in Fig. 24,

and insert the socket until it lightly bumps against

the handle cover.

MAINTENANCE AND INSPECTION

CAUTION:

Pull out battery before doing any inspection or

maintenance.

1. Inspecting the saw blade:

Since use of a dull saw blade will degrade efficiency

and cause possible motor malfunction, sharpen or

replace the saw blade as soon as abrasion is noted.

CAUTION:

If a dull saw blade is used, reactive force is increased

during cutting operation. Avoid the use of the dull

saw blade without repair.

2. Inspecting the mounting screws:

Regularly inspect all mounting screws and ensure

that they are properly tightened. Should any of the

screws be loose, retighten them immediately. Failure

to do so could result in serious hazard.

3. Maintenance of the motor

The motor unit winding is the very "heart" of the

power tool.

Exercise due care to ensure the winding does not

become damaged and/or wet with oil or water.

4. Inspecting the carbon brushes (Fig. 25)

The motor employs carbon brushes which are

consumable parts. Since and excessively worn

carbon brush can result in motor trouble, replace

the carbon brush with new ones when it becomes

worn to or near the "wear limit". In addition, always

keep carbon brushes clean and ensure that they

slide freely whthin the brush holders.
