GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings and all 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 fl ammable liquids, gases or dust. Power tools create sparks which may ignite the dust or 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.

b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch is in the off -position before connecting to power source and/or battery pack, picking up or carrying the tool.

Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on.

A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts.

Loose clothes, jewellery or long hair can be caught in moving parts.

g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.

Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools' operation.

If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Service

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

PRECAUTION

Keep children and infi rm persons away.

When not in use, tools should be stored out of reach of children and infi rm persons.

PRECAUTIONS ON USING CUTTER

1. Do NOT use any cutting tool other than a diamond wheel.
2. Don't use it for cutting of metallic materials. Diamond wheel may be broken or its service life may be remarkably reduced when it is used for cutting of metallic materials. Be sure not to use the wheel for cutting of metals.
3. Be sure to take an earth leakage breaker or isolating transformer as electric shock-preventive measures.
4. Pour on water while cutting or scribing concrete, tile or stone.
5. Keep the motor interior free of water.

6. Wear protective glasses to protect your eyes while cutting.

7. Prior to use, be sure to check the diamond wheel in such details as crack, broken part, bent part and the like. Don't use a diamond wheel if any of the above detect is found on the wheel. Also confi rm that no abnormality exists by actual test running.

8. Proceed with cutting operation when full speed has been reached.
9. Do NOT apply excessive force.
10. When cutting concrete, tile, or stone, the maximum cutting depth should be held to within 20mm.
11. Never touch diamond wheel while operating.
12. Never lay down the cutter while the diamond wheel is revolving.
13. Exercise care to position the cutter at a safe, stable spot when cutting.
14. Take good care of the power tool and keep it clean.

PRIOR TO OPERATION

1. Confirming the earth leakage breaker or isolating transformer

Before using this Cutter, confirm that an earth leakage breaker or isolating transformer as electric shock preventive measures is installed at the power supply to which the Cutter is connected.

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

1. Power switch

Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, and can cause serious injury.

1. Extension cord

When the work area is far away from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

5. Mounting the diamond wheel

For details, refer to the item "Mounting and dismounting the diamond wheel".

1. Confirm that the cutting depth adjusting lever is securely clamped.

7. Cutting depth adjustment (Fig. 1)

○ Loosen the cutting depth adjusting wing bolt and move the base to adjust the depth.

○ Tighten the wing bolt securely after adjusting the cutting depth.

CAUTION

○ Leaving the wing bolt loosened may result in injury. Securely tighten the wing bolt after adjusting the cutting depth.

When the cutting depth exceeds 20 mm, concrete, and so on must be cut in two steps. Never try to cut in one step; otherwise, the motor is liable to be overloaded and damaged may result. Also, cutting efficiency will be lower in such an instance.

MOUNTING AND DISMOUNTING THE DIAMOND WHEEL

CAUTION

○ Be sure to disconnect the attachment plug from the power receptacle to avoid serious trouble.

- Stop pouring water and select a moisture-free location for the operation mentioned above.

1. Mounting the diamond wheel

(1) Thoroughly remove dust accumulated on the spindle and washers.

(2) As shown in Fig. 2, the concave portions of washers (A) and (B) must be on the diamond wheel side.

(3) Thoroughly clamp the bolt.

2. Dismounting the diamond wheel

Use the provided wrenches to remove the bolt. (Fig. 3)

CAUTION

A diamond wheel for mounting on this equipment must have 20 mm internal diameter. No other sized diamond wheel should be used.

CUTTING PROCEDURES

1. Set the machine body (base) on the material to be cut; use the side on the base to align the diamond wheel with the cutting line. (Fig. 4)

2. Turn the switch ON with the diamond wheel initially kept off the material to be cut.

The power switch is turned ON when the trigger is pulled by one's finger, and is turned OFF when the trigger is released. The stopper is designed to prevent inadvertent operation of the machine and the trigger will not operate unless the stopper has first been pushed in. Turn the machine ON with the diamond wheel initially kept off the material to be cut. The power switch is turned ON by first depressing and holding down the stopper, and then pulling the trigger with one's finger. Once the trigger is ON, the stopper may be released and the tool may be operated by continuing to hold the trigger. The power switch is turned OFF when the trigger is released.

CAUTION

Do NOT use the diamond wheel for cutting along curves or at angles; otherwise, it may be damaged, resulting in extremely shortened service life.

Before starting to cut, confirm that the diamond wheel has attained full-speed revolution.

- Should the diamond wheel stop or make an abnormal noise while operating, promptly turn OFF the switch.

○ Always take care in preventing the power cord from coming near to the revolving diamond wheel.
When finished with a job, pull out the plug from the power receptacle.

MAINTENANCE AND INSPECTION

CAUTION

Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection. Using cracked, deformed or damaged wheels can lead to wheel breakage and resulting serious injury.

1. Inspecting the diamond wheel

Since use of a dull diamond wheel will cause motor malfunctioning and degraded efficiently, replace with a new one without delay when abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all screws and ensure that they are fully tightened. Should any of the screws be loosened, retighten them immediately. Failure to do so could result in serious hazard.

3. 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.

4. Inspecting the carbon brushes (Fig. 5)

The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon brush can result in motor trouble, replace the carbon brush with a new one having the same carbon brush No. shown in the figure when it becomes worn to or near the "wear limit". In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

5. Replacing carbon brushes

Remove the brush caps and carbon brushes. After replacing the carbon brushes, do not forget to tighten the brush caps properly.
