Safety Warnings

Electrical Safety

• Ensure electrical tool plugs match the outlet. Never modify the plug in any way or use adapter plugs with earthed (grounded) power tools. Properly matched, unmodified plugs and outlets reduce the risk of electric shock.
• Avoid contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. Contact with these surfaces increases the risk of electric shock.
• Keep electrical tools away from rain or wet conditions. Water entering a power tool significantly raises the risk of electric shock.
• If using an electrical tool in a damp location is unavoidable, ensure the power supply is protected by a Ground Fault Circuit Interrupter (GFCI). A GFCI reduces the risk of electric shock in such conditions.

Personal Safety

• Stay alert and focused. Always pay attention to what you are doing and use common sense when operating a power tool. Avoid using power tools if tired or under the influence of drugs, alcohol, or medication. A moment of inattention can result in serious personal injury.
• Prevent unintentional starting. Ensure the switch is in the OFF position before connecting the tool to a power source, attaching a battery pack, picking up, or carrying the tool. Carrying tools with your finger on the switch or connecting power while the tool is on increases the risk of accidental activation.
• Remove all adjusting keys or wrenches before turning on the tool. Leaving these attached to rotating parts can cause serious personal injury.
• Maintain proper footing and balance. Avoid overreaching, and always keep a stable stance to retain control of the tool in unexpected situations.
• Use dust extraction and collection systems if available. Properly connecting and using these systems helps reduce dust-related hazards.

Power Tool Use and Care

• Use the correct tool for the job. Do not force the power tool to perform tasks it is not designed for. The appropriate power tool will complete the task more efficiently and safely when used as intended.
• Ensure proper operation of the switch. Do not use the power tool if the switch does not properly turn it on and off. A tool that cannot be controlled via the switch is hazardous and should be repaired before use.
• Disconnect the power source before adjustments. Always unplug the tool or remove the battery pack before adjusting, changing accessories, or storing the tool. This precaution prevents accidental activation.
• Store tools securely and out of reach of children. Keep idle power tools in a safe location, away from children and individuals unfamiliar with their operation. Tools in the hands of untrained users can be dangerous.
• Maintain tools. Regularly inspect power tools for misalignment, binding of moving parts, breakage, or any condition that may affect their performance. Damaged tools should be repaired before use, as poorly maintained tools are a common cause of accidents.
• Keep cutting tools sharp and clean. Properly maintained and sharp cutting edges reduce the likelihood of binding and make the tool easier to control.
• Follow the tool's instructions and intended use. Use the power tool, accessories, and bits according to the provided instructions and the conditions of the task. Using tools for unintended applications can lead to hazardous situations.

Service

• Always have tools serviced by a qualified repair technician at Adendorff Machinery Mart www.adendorff.co.za, ensuring that only identical replacement parts are used. This guarantees the safety and performance of the tool.
• Adhere to maintenance guidelines. Follow the manufacturer's instructions for lubrication and accessory changes to maintain the tool's functionality and longevity.
• Maintain cleanliness. Keep handles and external surfaces dry, clean, and free from oil and grease. A clean tool provides better grip and reduces the risk of slipping during use.

PPE Requirements

• Use appropriate personal protective equipment. Always wear eye protection, and use additional protective equipment such as a dust mask, non-skid safety shoes, a hard hat, or hearing protection, depending on the conditions. These measures reduce the risk of injury.
• Dress appropriately. Avoid wearing loose clothing or jewellery, and ensure long hair is tied back. Keep hair, clothing, and gloves away from moving parts to prevent entanglement.

Operating Environment Requirements

• Keep the work area clean and well-lit. Cluttered or poorly lit spaces increase the risk of accidents.
• Avoid operating power tools in explosive atmospheres. Do not use tools in environments with flammable liquids, gases, or dust, as power tools generate sparks that could ignite these substances.
• Keep children and bystanders at a safe distance while operating a power tool. Distractions can lead to a loss of control, increasing the risk of injury.
• Disconnect the power before opening or maintenance.

Operating Instructions

Assembly

1. When unpacking the carton, you will notice that the base of the drill stand is positioned incorrectly. Remove it using a wrench and reinstall it in the correct direction.

2. Measure the distance from the center of the intended cut to the mounting slot location in the base. Follow the concrete anchor manufacturer's instructions for installation. Using a suitable tool (e.g., a rotary hammer), drill the correct sized hole for the anchor. Drive the anchor below flush.
3. Move the base into position and insert the anchor bolt, washer, and nut. Leave the nut finger-tight at this stage.

4. Using the bubble level (on top of the motor), adjust the four leveling bolts until the stand is level. Once level, fully tighten the center anchor bolt. If precise leveling is required, a carpenter's level may also be used.

Drilling Instructions

1. Press the "Reset" button on the PRCD interrupter device to energize the machine circuit. Then turn the machine on.

2. Open the water valve slightly and begin the cut gently. Apply very light feed pressure to prevent the bit from wandering until it has fully entered the cut.

3. Adjust the water feed as required: The exiting water should be a consistent slurry with the appearance of milk.
   • If the water is clear → reduce the flow.
   • If the water is thick and muddy → increase the flow.
   Ensure the water pressure is sufficient to flush cutting debris from the cut.
4. Once the bit is engaged, apply steady feed pressure for about 30 seconds. Then release feed pressure briefly to allow debris to escape and the bit to cool. Repeat this cycle until the cut is complete.
5. When nearing breakthrough, reduce feed pressure. At this stage, the bit is prone to sticking. Grip the machine firmly and proceed carefully.

Mounting the Core Bit

Steps:

• Make sure both the core bit and spindle are clean. Debris can cause excessive run-out, which may result in premature bit failure or safety hazards.
• Mount the core bit onto the spindle and tighten using two correct-sized wrenches. Do not use incorrect tools, as this may damage the spindle or bit.

Choosing the Correct Core Bit

Always ensure the core bit is suitable for the material you are drilling.

Maintenance & Service Intervals

Storage Instructions

• Keep the tool stored in a dry, level area, away from dampness, moisture, and rainfall.
• Allow the tool to cool down completely before storing.
• Ensure the tool is clean and dry before storage.
• Store the tool in a position where it cannot be accidentally stepped on or moved, especially to reach higher items.

DO NOT:

• Do not store the tool near an ignition source, such as a wood stove, gas or electric heater, or any appliance with a pilot light.
• Do not stack heavy or other items on top of the tool during storage.

IMPORTANT:

• Store the tool out of reach of children or individuals unfamiliar with its operation.
• Avoid direct sunlight or extreme temperatures. Store the tool indoors or in a safe, frost-free area.

Troubleshooting

When troubleshooting electric tools, start by checking the power source – ensure the tool is properly plugged into a functional outlet. Inspect the power switch, fuses, and any reset buttons for signs of malfunction. Look for visible damage to cords, connectors, or terminals, as these can interrupt the power flow. If the tool still doesn't operate, remove any obstructions, clean the contacts, and verify that all safety features or interlocks are properly engaged. Contact Adendorff Machinery Mart Authorised Service Centres to avoid further damage or safety hazards.

Disposal Guidelines

When disposing of electric and battery-operated tools, always follow local regulations and environmental guidelines. Start by removing any batteries, as they require separate handling due to their hazardous materials – recycle them at designated battery recycling centres or collection points.

For the tool itself, do not throw it in regular trash; instead, take it to an authorised e-waste recycling facility or a community hazardous waste disposal event.

Always erase any personal data stored in smart tools and ensure components are safely handled to prevent environmental contamination or injury.
