GENERAL POWER TOOL SAFETY WARNINGS

WARNING:

Read all safety warnings and instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
Power tools create sparks which may ignite the dust of fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply.
Use of an RCD reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication.

A moment of inattention while operating power tools may result in serious personal injury.

HOW TO USE THE CORDLESS MINI SAW

CAUTION:

○ Avoid carrying it with your finger on the switch. A sudden startup can result in an unexpected injury.
○ 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.
During use, press the base against the material while cutting.

Vibration can damage the saw blade if the base is not pressed firmly against the workpiece.

Furthermore, a tip of the saw blade can sometimes contact the inner wall of the pipe, damaging the saw blade.

○ Select a saw blade of the most appropriate length. Ideally, the length protruding from the base of the saw blade after subtracting the stroke should be larger than the material (see Fig. 16).
If you cut a large block of wood, etc., that exceeds the cutting capacity of a blade; there is a risk that the blade may contact with the inner wall of wood, etc., resulting in damage. (Fig. 17)
To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. Therefore, if the tool is overloaded, the motor may stop. However, this is not the trouble but the result of protection function. In this case, release the switch of tool and eliminate the causes of overloading.

1. Switch operation

(1) The tool is equipped with a lock-off button. To activate the trigger lock, move the button to the right position. Move the button to the left to operate the tool. (Fig. 18, Fig. 19)

Fig. 18

Fig. 19

CAUTION:

Always lock the switch when carrying or storing the tool eliminate unintentional starting.

(2) Trigger switch

This tool is equipped with a variable speed controlled trigger switch. The tool can be turned "ON" or "OFF" by squeezing or releasing the trigger. The blade plunger stroke rate can be adjusted from the minimum to maximum nameplate stroke rate by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed.

2. Cutting lumber

When cutting lumber, make sure that the workpiece is fastened firmly before beginning. (Fig. 20)

Line drawing of hands using a tool to cut or repair a wooden object (no text or symbols present)

Fig. 20

CAUTION:

Never apply any unreasonable force to the saw blade when cutting. Also remember to press the base against the lumber firmly.

Delay the feed speed when cutting the material into small circular arcs. An unreasonably fast feed may break the blade.

3. Cutting metallic materials

CAUTION:

○ Press the base firmly against the workpiece.

Never apply any unreasonable force to the saw blade when cutting. Doing so can easily break the blade.

The motor can be locked sometimes, depending on the combination of the material to be cut and the blade. Whenever the motor gets locked, switch it off immediately.

(1) Fasten a workpiece firmly before operation. (Fig. 21)

Fig. 21

(2) When cutting metallic materials, use proper machine oil (turbine oil, etc.). When not using liquid machine oil, apply grease over the workpiece.

CAUTION:

The service life of the saw blade will be drastically shortened if you don't use machine oil.

4. Plunge cutting

With this tool, you can perform pocket cutting on plywood panels and thin board materials. You can carry out pocket cutting quite easily with the saw blade installed in reverse as illustrated in Fig. 23, Fig. 25, and Fig. 27. Use the saw blade that is as short and thick as possible. Be sure to use caution during the cutting operation and observe the following procedures.

(1) Press the lower part (or the upper part) of the base against the material. Pull the switch trigger while keeping the tip of the saw blade apart from the material. (Fig. 22, Fig. 23)

(2) Raise the handle slowly and cut in with the saw blade little by little. (Fig. 24, Fig. 25)

(3) Hold the body firmly until the saw blade completely cuts into the material. (Fig. 26, Fig. 27)

CAUTION:

○ Avoid plunge cutting for metallic materials. This can easily damage the blade.
Never pull the switch trigger while the tip of the saw blade is pressed against the material. If you do so, the blade can easily be damaged when it collides with the material.
○ Make absolutely sure that you cut slowly while holding the body firmly. If you apply any unreasonable force to the saw blade during the cutting operation, the blade can easily be damaged.

5. Using the light

Pull the trigger switch to light up the light. The light keeps on lighting while the trigger switch is being pulled. The light goes out after releasing the trigger switch. (Fig. 28)

Fig. 28

CAUTION:

Do not look directly into the light. Such actions could result in eye injury.

6. Battery level warning lamp

The battery level can be checked by pulling the trigger switch while the power tool is in a no-load state. The battery level warning lamp lights when the battery power is very low. If this happens, charge the battery. (Fig. 29)

Fig. 29

NOTE:

☐ The level at which the battery level warning lamp lights may vary due to the ambient temperature, characteristics of the battery, etc. and is intended only as a guide.
☐ The battery level warning lamp may light when the power tool is overloaded. This does not mean that the battery power is very low.
Be sure to check the battery level while the tool is in a no-load state.

MAINTENANCE AND INSPECTION

CAUTION: Pull out battery before doing any inspection or maintenance.

1. Inspecting the blade

Continued use of a dull or damaged blade will result in reduced cutting efficiency and may cause overloading of the motor. Replace the blade with a new one as soon as excessive abrasion is noted.

1. Check the Screws

Loose screws are dangerous. Regularly inspect them and make sure they are tight.

CAUTION:

Using this power tool with loosened screws is extremely dangerous.

1. 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.

1. Check for Dust

Dust may be removed with a soft cloth or a cloth dampened with soapy water.

Do not use bleach, chlorine, gasoline or thinner, for they may damage the plastics.

1. Disposal of the exhausted battery
