3. Regulating the guide (Fig. 17)

The cutting position can be regulated by moving

the guide to the left or right after loosening its knob

bolt. The guide may be mounted on either the right

or left side of the tool.

HOW TO USE

1. Operation of switch (Fig. 18)

(switch trigger and light switch)

(1) For safe operation of the machine, a “switch lock”

is provided on the side of a handle.

If the “switch trigger” is pulled in a state where

“switch lock” is pressed in the direction of the

arrow mark, the main switch can be turned ON.

And the “switch lock” is used as the “light switch”.

If the “switch lock (light switch)” is pressed in a

state, the light is turned ON.

(2) After the switch is turned ON, even when you

release your hand from the switch lock, the body

continues running and the light continues being

turned ON as long as you keep on pulling the

switch trigger.

(3) If you release the switch trigger, you can turn OFF

the switch and the “switch lock” returns to the

original position automatically and the light turns

OFF too.

CAUTION

⅜ Do not fix and secure the switch lock. Besides, keep

your finger off the switch trigger when the circular

saw is being carried around. Otherwise, the main

body switch can be inadvertently turned ON,

resulting in unexpected accidents.

⅜ Keep the light ON during cutting operation only.

If it is lit ON in other cases, the main body switch

can be inadvertently turned ON, resulting in

unexpected accidents.

⅜ If the main body is left as it is with the battery

inserted, there can be a case where the [switch lock]

touches the floor and/or wall surface and lights up

continuously, depending on the direction of the

body. Be careful, since continuous lighting can easily

make a full-charged battery go dead in about 3

hours.

2. Cutting procedures

CAUTION

⅜ Recheck that the saw blade is securely clamped.

⅜ Confirm that the wing nut for adjusting the slot

depth, the wing bolt for adjusting the angle of

inclination are securely clamped.

(1) Place the base on the material, then align the

premarked line and the sawblade with the notch

at the front of the base (Fig. 16).

When the base is not slanted, use the large cutout

as the guide (Fig. 16, Fig. 19(A)).

If the base is slanted (45 degrees), use the small

front scale as the guide (Fig. 16, Fig. 19(B)).

(2) Ensure that the switch is turned to the ON position

before the saw blade comes in contact with the

lumber. The switch is turned ON when the trigger

is squeezed; and OFF when the trigger is released.

Moving the saw straight at a constant speed will

produce optimum cutting.

As the internal chemical substance of new batteries

and batteries that have not been used for an

extended period is not activated, the electric

discharge might be low when using them the first

and second time. This is a temporary phenomenon,

and normal time required for recharging will be

restored by recharging the batteries 2 – 3 times.

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. Setting up and checking the work environment

Check if the work environment is suitable by

following the precautions.

2. Prepare a wooden workbench (Fig. 13)

Since the saw blade will extend beyond the lower

surface of the lumber, place the lumber on a

workbench when cutting. If a square block is utilized

as a workbench, select level ground to ensure it

is properly stabilized. An unstable workbench will

result in hazardous operation.

CAUTION

To avoid possible accident, always ensure that the

portion of lumber remaining after cutting is securely

anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE

CAUTION

Pull out battery before doing any adjusting.

1. Adjusting the cutting depth

As shown in Fig. 14, hold the handle with one hand

while loosening the wing nut with the other.

The cutting depth can be adjusted by moving the

base to the desired position. In such manner adjust

the cutting depth and then securely retighten the

wing nut.

2. Adjusting the angle of inclination

As shown in Fig. 15 by loosening the wing bolt on

the incline gauge, the saw blade may be inclined

to a maximum angle of 50° in relation to the base.

After having completed the adjustment, reconfirm

that the wing bolt are firmly tightened.

NOTE

Values of the inclined gauge provided on the base

merely serve as a rough guideline. For cutting

operation at an inclined posture, use the circular

saw after adjusting the angle between the base and

the saw blade with a protractor, etc.
