GENERAL SAFETY RULES

(FOR All BATTERY OPERATED TOOLS)
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

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 or fumes.

3. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.
   Electrical Safety
   

4. 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.

5. Use battery operated tool only with specifically designated battery pack. Use of any other batteries may create a risk of fire.
   Personal Safety

6. 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.

7. 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.

8. Avoid accidental starting. Be sure switch is in the locked or off position before inserting battery pack. Carrying tools with your finger on the switch or inserting the battery pack into a tool with the switch on invites accidents.

9. 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.

10. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations.

11. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.
    Tool Use and Care

12. 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.

13. 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.

14. Do not use tool if switch does not turn it on or off. A tool that cannot be controlled with the switch is dangerous and must be repaired.

15. Disconnect battery pack from tool or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tool.
    Such preventive safety measures reduce the risk of starting the tool accidentally.

16. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

17. 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.

18. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edge are less likely to bind and are easier to control.

19. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

20. 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.
    SERVICE

21. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may result in a risk of injury.

22. 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 instructions may create a risk of shock or injury.

SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to cordless cutter safety rules. If you use this tool unsafely or incorrectly, you can  suffer serious personal injury.

1. DANGER! Keep hands away from cutting area and wheel. Keep your second hand on auxiliary handle or motor housing. If both hands are holding the tool, they cannot be cut by the wheel.

2. Keep your body positioned to either side of the wheel, but not in line with the wheel. KICKBACK could cause the tool to jump backwards. (See “Causes and Operator Prevention of Kickback”)

3. Do not reach underneath the work.

4. Always observe that the wheel has stopped spinning before placing tool down on bench or floor. A coasting wheel will cause the tool to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the wheel to stop after switch is released.

5. NEVER hold piece being cut in your hands or across your leg. It is important to support the work properly to minimize body exposure, wheel binding, or loss of control.

6. 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.

7. When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance for wheel binding.

8. Always use wheels with correct size and shape (diamond vs. round) arbor holes. Wheels that do not match the mounting hardware of the tool will run eccentrically, causing loss of control.

9. Never use damaged or incorrect wheel washers or bolts. The wheel washers and bolt were specially designed for your tool, for optimum performance and safety of operation.

10. Causes and Operator Prevention of Kickback: Kickback is a sudden reaction to a pinched, bound, or misaligned wheel, causing an uncontrolled tool to lift up and out of the workpiece toward the operator. When the wheel is pinched or bound tightly by the kerf closing down, the wheel stalls and the motor reaction drives the unit rapidly back toward the operator. If the wheel becomes twisted or misaligned in the cut, the teeth at the back edge of the wheel can dig into the top surface of the wood causing the wheel 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:
    Maintain a firm grip on the tool 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. When wheel is binding, or when interrupting a cut for any reason, release the trigger and hold the tool motionless in the material until the wheel  comes to a complete stop. Never attempt to remove the tool from the work or pull the tool backward while the wheel is in motion or KICKBACK may occur. Investigate and take corrective actions to eliminate the cause of wheel binding. When restarting a tool in the workpiece, center the wheel in the kerf and check that teeth are not engaged into the material. If wheel is binding, it may walk up or KICKBACK from the workpiece as the tool is restarted. Support large panels to minimize the risk of wheel 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. To minimize the risk of wheel pinching and kickback. When cutting operation requires the resting of the tool on the workpiece, the tool shall be rested on the larger portion and the smaller piece cut off.
    Do not use dull or damaged wheel. Unsharpened or improperly set wheels produce narrow kerf causing excessive friction, wheel binding and KICKBACK. Wheel depth and bevel adjusting locking levers must be tight and secure before making cut. If wheel adjustment shifts while cutting, it will cause binding and KICKBACK. Use extra caution when making a “Pocket Cut” into existing walls or other blind areas. The protruding wheel may cut objects that can cause KICKBACK.

11. Use only diamond wheels. NEVER use tool with wood cutting blades or other sawblades. Such blades when used on this tool frequently kick and cause loss of control leading to personal injury.

12. Check the wheel carefully for cracks or damage before operation. Replace cracked or damaged wheel immediately.

13. Use only flanges specified for this tool.

14. Be careful not to damage the spindle, flanges (especially the installing surface) or bolt. Damage to these parts could result in wheel breakage.

15. Hold the tool firmly.

16. Make sure the wheel is not contacting the workpiece before the switch is turned on.

17. Wait until the wheel attains full speed before cutting.

18. Stop operation immediately if you notice anything abnormal.

19. Never attempt to cut with the tool held upside down in a vise. This can lead to serious accidents, because it is extremely dangerous.

20. Do not stop the wheel by lateral pressure on the disc.

21. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

OPERATION

1. Base

Hold the tool firmly. Set the base plate on the workpiece to be cut without the wheel making any contact. Then turn the tool on and wait until the wheel attains full speed. Feed water to the wheel by adjusting the water cock to obtain a gentle flow of water. Move the tool forward over the workpiece surface, keeping it flat and advancing smoothly until the cutting is completed. Keep your cutting line straight and your speed of advance uniform.
For fine, clean cuts, cut slowly. (When cutting glass plate 5 mm (3/16”) thick, cut at about 250 mm/min (9-7/8”/min). When cutting tile 10 mm (3/8”) thick, cut at about 300 mm/min (11-13/16”/min).) Also slow down as you complete a cut to avoid breaking or cracking the workpiece being cut.

CAUTION:

• Be sure to hold the workpiece firmly down on a stable bench or table during operation.
• Do not twist or force the tool in the cut, or the motor may be overloaded or the workpiece may break.
• Do not use the tool with the wheel in an upward or sideways position.
• When cutting glass plate, it is recommended to attach a rubber plate (optional accessory) on the base of the tool to prevent the workpiece surface from being scratched.
• The wheel for this tool is a wet-type wheel for glass and tile applications. Be sure to feed water to the wheel during operation.
• If the cutting action of the wheel begins to diminish, dress the cutting edge of the wheel using an old discarded coarse grit bench grinder wheel or concrete block. Dress by  pressing lightly on the outer edge of the wheel.
