Lower guard function
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
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
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
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 lower guard moves smoothly and freely.
19.Never use the circular saw with its lower guard 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 diameter should be 125 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 (Fig. 2). 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.
To avoid kickback, do support board or panel near the cut.
