GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS

HITACHI C 14DMR - GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS - 1

WARNING: Read and understand all instructions.

Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

1. Work Area

(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
(2) 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.
(3) Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.

2. Electrical Safety

(1) A battery operated tool with integral batteries or a separate battery pack must be recharged only with the specified charger for the battery.
A charger that may be suitable for one type of battery may create a risk of fire when used with another battery.
(2) Use battery operated tool only with specifically designed battery pack.
Use of any other batteries may create a risk of fire.

3. Personal Safety

(1) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
(3) Avoid accidental starting. Be sure switch is off position before inserting battery. Carrying tools with your finger on the switch or inserting the battery pack into a tool with the switch on invites accidents.
(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.
(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.
(6) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

4. Tool Use and Care

(1) Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
(2) Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
(3) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
(4) Disconnect battery pack from tool or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tools. Such preventive safety measures reduce the risk of starting the tool accidentally.
(5) Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
(6) When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another.
Shorting the battery terminals together may cause sparks, burns, or a fire.
(7) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control.
(8) Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
(9) Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may create a risk of injury when used on another tool.

5. Service

(1) Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
(2) When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instruction may create a risk of electric shock or injury.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

  • Lead from lead-based paints,
  • Crystalline silica from bricks and cement and other masonry products, and
  • Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

SPECIFIC SAFETY RULES

  1. DANGER! Keep hands away from cutting area and blade. Keep your second hand on auxiliary handle or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
    Keep your body positioned to either side of the saw blade, but not in line with the saw blade. KICKBACK could cause the saw to jump backwards. (See KICKBACK)
    Do not reach underneath the work. The guard can not protect you from the blade below the work.
  2. Check lower guard for proper closing before each use. Do not operate 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.
  3. Check the operation and condition of the lower guard spring. If the guard 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 buildup of debris.
  4. lower guard should be retracted manually only for special cuts such as “Pocket Cuts” and “Compound Cuts.” Raise lower guard by Retracting Handle. As soon as blade enters the material, lower guard must be released. For all other sawing, the lower guard should operate automatically.
  5. 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.
  6. NEVER hold piece being cut in your hands or across your leg. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
  7. Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts of the tool "live" and shock the operator.
  8. When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance for blade binding.
  9. Always use blades with correct size and shape (diamond vs. round) arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
  10. Never use damaged or incorrect blade washers or bolts. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.
  11. Causes and Operator Prevention of Kickback:
    Kickback is a sudden reaction to a pinched, bound, or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator.
    When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator.
    If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.
    Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

  12. Maintain a firm grip on the saw and position your body and arm in a way that allows you to resist KICKBACK forces. KICKBACK forces can be controlled by the operator, if proper precautions are taken.

  13. 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.
  14. When restarting a saw in the workpiece, center the saw blade in the kerf and check that teeth are not engaged into the material. If saw blade is binding, it may walk up or KICKBACK from the workpiece as the saw is restarted.
  15. 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.

HITACHI C 14DMR - Remove the battery from the battery charger - 1

CAUTION:

  • When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging.
  • If the battery is recharged when it is warm due to battery use or exposure to sunlight, the pilot lamp may light in green.
    The battery will not be recharged. In such a case, let the battery cool before charging.
  • When the pilot lamp flickers rapidly in red (at 0.2-second intervals), check for and take out any foreign objects in the charger's battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to an authorized Service Center.

Regarding electric discharge in case of new batteries, etc.

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.

OPERAION

WARNING:

  • Never touch the moving parts.
  • Never operate the circular saw with the saw blade turned upward or to the side.
  • 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.
  • 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.

CAUTION:

  • Don't remove circular saw from workpiece during a cut while the saw blade is moving.
  • Pull out the battery after completing operation.

NOTE:

Take care not to lock the motor. If the motor is locked, immediately turn the power off. If the motor is locked for a while, the motor or battery may be burnt.

1. Operation of switch (Switch trigger and light switch)

For safe operation of the machine, a "switch lock" is provided on the side of a handle.

If the “switch lock” is pulled in a state where it is pressed in the direction of the arrow mark, the main switch can be turned ON.

(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.

(1) Switch lock is used as the "light switch". If the "switch lock (light switch)" is pulled 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.

2. Working performance per single charge (Reference data)

○ Cutting capability differs according to the condition of lumber, type of saw blade, ambient temperature, battery characteristics, etc.

3. Cutting procedures

CAUTION:

  • Recheck that the saw blade is securely clamped.
  • Confirm that the wing-nut for adjusting the slot depth, the wing-bolt for adjusting the angle of inclination.

(1) Place the base on the material, then align the premarked line and the saw blade with the notch at the front of the base (Fig. 14).
(2) When the base is not inclined, use the large notch (Fig. 14, Fig. 15). If the base is inclined (45 degrees), use the small notch (Fig. 14, Fig. 16).

NOTE: When using the saw at the inclination of 45 degrees, use both the marks of on the bevel plate and [45] on the inclined gauge of the base (Fig. 17). What's more, if it is absolutely essential to use the saw at a precise angle, make adjustment using a protractor, etc.

(3) 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.

CAUTION:

  • Before starting to saw, ensure that the saw blade has reached full speed revolution.
  • Should the saw blade be stopped or made an abnormal noise during operation, turn off the switch immediately.
  • When finished with a job, pull out the battery from the main body.
