GENERAL SAFETY TOOLS

(For All 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.
Warning: The body of the machine may get warm after extended use. If this occurs, turn off the machine and let it cool down to avoid risk of damaging the unit, or 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. Power tool plugs must match the outlet. Never modify the plugs in any way. Do not use any adapter plugs with grounded power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. Do not change the plug in any way.
   Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system.

5. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.

6. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

7. Do not abuse the cord. Never use the cord to carry the tool or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

8. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.” These cords are rated for outdoor use and reduce the risk of electric shock.
   PERSONAL SAFETY

9. 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.

10. 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.

11. Avoid accidental starting. Be sure switch is off before plug- ging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.

12. 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.

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

14. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, and hearing protection must be used for appropriate conditions. Ordinary eye or sun glasses are NOT eye protection.
    TOOL USE AND CARE

15. Use clamps or other practical ways to secure and support the workplace to a stable platform. Holding the workpiece by hand or against your body is unstable and may lead to loss of control.

16. 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.

17. 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.

18. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventative safety measures reduce the risk of starting the tool accidentally.

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

20. 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.

21. 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.

22. Use only proper 7” DiamaPro Systems tools with this model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.

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

24. When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of the manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electric shock or injury.

25. Always use with a DiamaPro Systems dust shroud.

26. Failure to follow proper use guidelines will result in void of warranty.

SPECIFIC SAFETY RULES

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

1. Always use a DiamaPro Systems dust shroud. Shrouds protect opera- tor from broken wheel fragments.
2. Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories running over rated speed can fly apart and cause injury.
3. Do not let the tool come in contact with live wire. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
4. Always use safety glasses or goggles. Ordinary eye or sun glasses are NOT safety glasses.
5. Check the wheel carefully for cracks or damages before operation. Replace cracked or damaged wheel immediately. Run the tool (with guard) at no load for about a minute, holding tool away from others. If wheel is flawed, it will likely separate during this  est.
6. Only use with DiamaPro Systems 7” cupwheels and abrasives.
7. Be careful not to damage the spindle, the flange (especially the installing surface) or the outer flange. Damage to these parts could result in wheel breakage.
8. NEVER use tool with wood cutting blades or other saw blades. Such blades when used on a grinder frequently kick and cause loss of control leading to personal injury.
9. Hold the tool firmly.
10. Keep hands away from rotating parts.
11. Make sure cord is clear of wheel. Do not wrap cord around your arm or wrist. If control of tool is lost, cord may become wrapped around you and cause personal injury.
12. Make sure the wheel is not contacting the workpiece before the switch is turned on.
13. Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel.
14. Use the specified surface of the wheel to perform the grinding.
15. Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons or flammable materials.
16. Do not leave the tool running. Operate the tool only when handheld.
17. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin.
18. ALWAYS wear proper apparel including long sleeve shirts. Leather gloves and shop aprons to protect skin from contact with hot grindings.
19. Use of this tool to grind or sand some products. Paints and wood could expose user to dust containing hazardous substances. Use appropriate respiratory protection.
20. Must use with DiamaPro Hepa Filtered Dust Collector

Installing or removing grinding wheel
CAUTION:

• When using an abrasive cut-off wheel, be sure to use only the supplied wheel guard, inner flange, and outer flange designed for use with cut-off wheels.

1. Mount the inner flange onto the spindle. Fit the wheel/disc on the inner flange and screw the outer flange onto the spindle (Fig 3).
2. To tighten the outer flange, press the shaft lock firmly so that the spindle cannot revolve, then use the lock nut wrench and securely tighten clockwise (Fig 4). 3. To remove the wheel, follow the installation procedure in reverse.
   ※NOTICE: The groove of INNER FLANGE must align the flatness of spindle when you install the wheel and tighten enough.

 Side grip (Fig 5).
CAUTION:
Always be sure that the side grip is installed securely before operation. Screw the side grip securely on the position of the tool as shown in Fig5.
Hold the side grip firmly by hand to better control the tool.

 Switch Action (Fig 6).
CAUTION:

• Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.
• Switch cannot be locked in “ON” position for safety of operator during use. Apply caution when using tool and maintain firm grasp on tool.
