General safety rules

Warning! Read and understand all instructions, failure to follow all instructions listed below may result in electric shock, fire, and serious personal injury.

Work area

1. keep the work area clean and benches invite injuries
2. do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids gases or dust power tools create sparks that may ignite the dust or fumes
3. keep bystanders children and visitors away while operating a power tool, distraction can cause you to lose control of Electrical safety
4. Power tools must be plugged into an outlet properly installed or grounded in accordance with all codes and ordinances. Never modify the Plug in any way. Do not use any adaptor plugs with grounded (earthed) power tools. The original Plug and proper outlet may reduce the risk of electric shock.
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 tools or pull their plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged or entangled cords increase the risk of electric shock.
8. When operating a power tool outside, use only extension cords intended for outdoor use. These cords may 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 tools 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 the switch is off before plugging 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 enable better control of the tool in unexpected situations.
14. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Ordinary eye or sunglasses are NOT eye protection.
15. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards. Tool Use and Care
16. Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer when used for the applications which it is designed for.
17. Do not use the tool if the 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 preventive safety measures reduce the risk of starting the tool accidentally.
19. Store idle tools out of 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 operation of the tool. If damaged have the tool serviced before using. Many accidents are caused by poorly maintained tools.
22. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
23. Service
24. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
25. 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 electric shock or injury.

Voltage warning
Before connecting the tool to a power source (receptacle, outlet, etc.), be sure the voltage supplied is the same as that specified on the nameplate of the tool. A power source with a voltage greater than that specified for the tool can result in SERIOUS INJURY to the user, as well as damage to the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage less than the nameplate rating is harmful to the motor.
Additional safety rules

1. Always use an RCD (residual current-operated device) interrupter protection, with actuating current not more than 30mA and actuating time not more than 0,1s, and regularly check the operation sensitivity of the protector; or use an isolating transformer to connect with the mains network, with the main technical parameters of which should keep accordance with the following table.
2. Check the earth (ground) connection of the plug before plugging in the machine.
3. Always check the fault-current safety switch for correct functioning before starting a drilling operation.
4. Wear sensible, protective clothing and footwear plus safety goggles, work gloves, ear protectors, and a hard hat (or helmet).
5. Do not switch on the machine under load conditions; this might cause personal injury or damage to the machine.
6. Ensure the work area is tidy, well-lit, and ventilated. In case of operation in a closed room or basement, make sure that the air is in good condition (plenty of oxygen, no toxic gas) before operation.
7. Hold the machine only by insulated surfaces when performing an operation where the cutting tool may contact hidden wiring brown cord, contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
8. Ensure that no water is allowed to get into the drive unit during operation, do not expose the motor to rain or snow.
9. Do not work near flammable/explosive gases, liquids or solids. Never drill into walls/floors containing gas/water pipes or electrical cables. If in doubt, check both sides using a metal detector or cable-avoiding tool.
10. Take appropriate precautions to ensure that, in the event of a drilling core dropping out, no personal injury or material damage will result.
11. Keep cable and hose away from the cutting area, and away from the heat, oil, and sharp edges.
12. Keep hands away from cutting edges and all rotating parts.
13. Ensure the core bit has an adequate, constant supply of water for cooling lubrication. This also allows the drilled-out material to be swilled from the borehole.
14. Do not use this machine for dry boring.
15. Do not block the air intake of the motor as its cooling capacity would then decrease and the motor could burn out.
16. This machine is not for hand-held use. Always install the machine securely.
17. In case ceiling drilling is required, be sure to fix the water collector securely and pay attention so that the water will not leak out of the collector.
18. Do not leave this machine unattended while the motor is running.
19. Keep the machine clean, paying special attention to the motor and switch. Clean up regularly rather than at end of the hire period.
20. Treat core bits with care. Avoid knocking them or allowing them to drop onto the work surface.

Operation

Attention: Our company does not assume any responsibility because the machine is not solid or fixed safety facilities are not in appropriate place cause accident.

1. The fixation of expansion bolt: Drill a hole by impact drill in the set position, screw the expansion bolt, make sure it is tight, fix the diamond drill machine on it, and adjust the four regulating screws to keep the drill machine from swinging.
2. The fixation of support rod: determine the drilling location, and supporting rod, adjust the length of the push rod, and adjust the fastening screws, so that the drilling rig substructure has full contact face, and ensure the drill bit and drill vertical face, no swing.
3. Fix the drill bit, connect the power and water supply, move adjusting tools, switch on when the drill machine is not loaded, and check the drill bit and sound, if everything is fine, then open the water tap, the machine can start to drill when water flow from the drill bit.
4. Take it slow when at first, when the drill bit is cut in the wall, change to normal speed.
5. Both mechanical and electronic protections exist in drill machines. When drilling, if the motor is working, while the drill bit is not moving, means the drill bit needs to be sharpened or the feeding speed is too fast, please pull out the drill bit and then re-feed. If the motor stops short when drilling, please return the machine and slow down the feed speed.
6. After using a period of time, the abrasion of the friction plate may cause a slip. Please take the clutch gear out of the gearbox and change friction plates to a unified size, tight the screws. Then put the gear back to the gearbox (This step should be done by a trained person).

Instruction of Shifting Gear

In order to improve efficiency, some machines are designed with a 2-speed gear shift, high speed(H speed), and low speed(L speed). H speed is for drilling on soft material with a small drill bit, and L speed is for drilling on hard material with a large drill bit. Shift when the machine stops or will stop. The shift in place. If the spindle doesn’t rotate or there is some noise after starting up, the gear may not shift in place. Turn off the machine immediately, and then shift the gear to the proper place, rotate the spindle back and forth (easy to shift) at the same time till the shift is in place. Do not shift when the machine is full-speed operated, overloaded, or stuck.

Maintenance

Warning: Always and on principle pull the mains plug before beginning with works of maintenance or repairs.
Clean the machine with a dry or moist cleaning rag and not with a jet of water, make sure the water does not go into the motor and switch box. Keep the ventilation apertures clean, do not forget to clean the core bit thread and grease it, get all screws checked, and tighten. Have your tool only repaired by qualified personnel and only with original spare parts. Or else, it may cause damage to a person or machine.

Carbon Brush

After you have used the machine for about 300 hours you should check the carbon brushes for wear and replace them if necessary. Like any other work on the motor, this must be done by an electrical specialist.
