SAFETY INSTRUCTIONS FOR SAWS WITH

PENDULUM GUARD OR TOW GUARD

a) Check lower guard for proper closing before each use.

Do not operate the saw if lower guard does not move

freely and close instantly. Never clamp or tie the

lower guard into the open position.

If saw is accidentally dropped, lower guard may be

bent.

Raise the lower guard with the retracting handle

and make sure it moves freely and does not touch

the blade or any other part, in all angles and depths

of cut.

b) Check the operation of the lower guard spring. If the

guard and the spring are not operating properly, they

must be serviced before use.

Lower guard may operate sluggishly due to damaged

parts, gummy deposits, or a build-up of debris.

c) Lower guard may be retracted manually only for

special cuts such as “plunge cuts“ and “compound

cuts“. Raise lower guard by retracting handle and as

soon as blade enters the material, the lower guard

must be released.

For all other sawing, the lower guard should operate

automatically.

d) Always observe that the lower guard is covering the

blade before placing saw down on bench or floor.

An unprotected, coasting blade will cause the saw to

walk backwards, cutting whatever is in its path.

Be aware of the time it takes for the blade to stop

after switch is released.

PRECAUTIONS ON USING CORDLESS

CIRCULAR SAW

1. Always charge the battery at a temperature of 10

– 40°C. A temperature of less than 10°C will result

in over charging which is dangerous. The battery

cannot be charged at a temperature higher than

40°C.

The most suitable temperature for charging is that

of 20 – 25°C.

2. When one charging is completed, leave the charger

for about 15 minutes before the next charging of

battery.

Do not charge more than two batteries

consecutively.

3. Do not allow foreign matter to enter the hole for

connecting the rechargeable battery.

4. Never disassemble the rechargeable battery and

charger.

5. Never short-circuit the rechargeable battery. Short-

circuiting the battery will cause a great electric

current and overheat. It results in burn or damage

to the battery.

6. Do not dispose of the battery in fire.

If the battery is burnt, it may explode.

7. When using this unit continuously, the unit may

overheat, leading to damage in the motor and

switch. Please leave it without using it for

approximately 15 minutes.

8. Do not insert object into the air ventilation slots

of the charger.

Inserting metal objects or inflammables into the

charger air ventilation slots will result in electrical

shock hazard or damaged charger.

9. Using an exhausted battery will damage the

charger.

10. Bring the battery to the shop from which it was

purchased as soon as the post-charging battery

life becomes too short for practical use. Do not

dispose of the exhausted battery.

11. Wear earplugs to protect your ears during

operation.

12. Always hold the handle of the power tool firmly.

Otherwise the counterforce produced may result

in inaccurate and even dangerous operation.

13. Do not use saw blades which are deformed or

cracked.

14. Do not use saw blades made of high speed steel.

15. Do not use saw blades which do not comply with

the characteristics specified in these instructions.

16. Do not stop the saw blades by lateral pressure

on the disc.

17. Always keep the saw blades sharp.

18. Ensure that the safety cover moves smoothly and

freely.

19. Never use the circular saw with its safety cover

fixed in the open position.

20. Ensure that the retraction mechanism of the guard

system operates correctly.

21. The saw blades body must be thinner than the

riving knife and the width of cut, or kerf (with

teeth set) must be greater than the thickness of

the riving knife.

22. Never operate the circular saw with the saw blade

turned upward or the side.

23. Ensure that the material is free of foreign matters

such as nails.

24. The riving knife should always be used except

when plunging in the middle of the workpiece.

25. The saw blades range should be from 165 mm

to 150 mm.

26. Be careful of brake kickback.

This circular saw features an electric brake that

functions when the switch is released. As there

is some kickback when the brake functions, be

sure to hold the main body securely.

27. Avoid cutting in the state where the base has

floated up from the material.

When blade is binding, or when interrupting a cut

for any reason, release the trigger and hold the

saw motionless in the material until the blade

comes to a complete stop. Never attempt to

remove the saw from the work or pull the saw

backward while the blade is in motion or KICKBACK

may occur. Investigate and take corrective actions

to eliminate the cause of blade binding.

28. Support large panels to minimize the risk of blade

pinching and KICKBACK. Large panels tend to sag

under their own weight. Supports must be placed

under the panel on both sides, near the line of

cut and near the edge of the panel as shown in

Fig. 1.

To minimize the risk of blade pinching and kickback.

When cutting operation requires the resting of the

saw on the work piece, the saw shall be rested

on the larger portion and the smaller piece cut

off.

29. Use extra caution when making a “Pocket Cut”

into existing walls or other blind areas. The

protruding blade may cut objects that can cause

KICKBACK.

NEVER place your hand or fingers behind the saw

(Fig. 3). If kickback occurs, the saw could easily

jump backwards over your hand, possibly causing

severe injury.
