General Safety Instructions

Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Keep this manual for future reference.

• Work Area Safety: Keep the work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators.
• Personal Safety: Always wear eye protection. Use hearing protection when operating the tool for extended periods. Wear a dust mask if working in dusty conditions. Dress properly; avoid loose clothing or jewelry.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
• Service: 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.

Setup and Assembly

Before starting any work, ensure the tool is disconnected from the power supply.

1. Unpacking: Carefully remove the demolition hammer and all accessories from the packaging. Inspect for any damage.
2. Attaching the Auxiliary Handle: Loosen the auxiliary handle clamp. Position the handle to a comfortable and secure operating position, then tighten the clamp firmly.
3. Inserting the Chisel/Breaker Bit:
   • Clean the shank of the chisel/breaker bit.
   • Apply a small amount of grease to the bit shank.
   • Insert the bit into the tool holder until it locks into place. Pull on the bit to ensure it is securely fastened.
4. Power Connection: Ensure the power switch is in the "OFF" position. Connect the power cord to a suitable power outlet (12 Volts, 900W capacity recommended).

Operating Instructions

Always wear appropriate personal protective equipment (PPE) including safety glasses, hearing protection, and gloves during operation.

1. Starting the Tool:
   • Hold the tool firmly with both hands using the main handle and auxiliary handle.
   • Press the ON/OFF switch to start the tool.
   • The tool features a Lock Speed Button for continuous operation without holding the trigger. Press the trigger, then press the lock button. To release, press the trigger again.
2. Demolition Work:
   • Position the chisel bit against the material to be broken.
   • Apply moderate pressure. Allow the tool to do the work; excessive force can reduce efficiency and damage the tool.

3. Stopping the Tool: Release the ON/OFF switch. If the lock speed button was engaged, press the trigger once to disengage it, then release.

Important: Do not operate the tool without a bit inserted, as this can cause damage to the hammering mechanism.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your tool. Always disconnect the tool from the power supply before performing any maintenance.

• Cleaning:
  • After each use, clean the tool housing with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
  • Clear any dust or debris from the ventilation openings to prevent overheating.
  • Clean the tool holder and bit shank regularly to ensure smooth bit insertion and removal.
• Lubrication: The internal hammering mechanism requires periodic lubrication. Refer to the service center for proper lubrication procedures, typically every 50 hours of operation or annually.
