1. Introduction

This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your Berserker 45HM SDS-Max Demolition Hammer. Please read these instructions carefully before using the tool to ensure proper function and user safety. The Berserker 45HM is designed for demolition, chipping, and breaking applications in concrete, block, brick, tile, and stucco. It features a powerful 1300W motor and an SDS-Max bit system for efficient material removal.

2. General Safety Instructions

Always observe the following safety precautions when operating the demolition hammer to prevent electric shock, fire, and serious injury.

• 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. Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges, or moving parts.
• Personal Safety: Always wear eye protection (safety goggles) and hearing protection (earplugs or earmuffs). Use a dust mask if operations create dust. Wear heavy-duty gloves. Dress properly; do not wear loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts.
• 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. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
• Specific Demolition Hammer Safety: The Berserker 45HM has a "hammer only" function and "variable-lock positioning" function. NO DRILLING function is available. Adapts only to SDS-Max type chisels. Be aware of hidden electrical wires, water pipes, or gas lines when working on walls or floors.

6.4 Demolition Techniques

• Always hold the tool firmly with both hands.
• Apply steady, moderate pressure. Do not lean heavily on the tool; let the hammer mechanism do the work.
• Start chipping at the edge of the material or at pre-drilled holes for easier breaking.
• Work in small sections to maintain control and prevent material from falling unexpectedly.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your demolition hammer. Always unplug the tool before performing any maintenance.

7.1 Lubrication (Greasing)

The Berserker 45HM features an external grease filler for easy lubrication. Refer to the included grease container for recommended type and frequency. Typically, grease should be applied every 40-50 hours of operation or as needed.

2. Unscrew the cap.
3. Using the provided grease or a suitable equivalent, inject a small amount of grease into the opening. Do not overfill.
4. Replace and tighten the cap securely.

7.2 Carbon Brush Replacement

Carbon brushes wear down over time and need replacement to maintain motor performance. The tool is supplied with a replaceable set of carbon brushes.

1. Locate the carbon brush caps on the sides of the motor housing.
2. Using a screwdriver or the provided wrench, unscrew the caps.
3. Carefully remove the old carbon brushes.
4. Insert the new carbon brushes, ensuring they are oriented correctly.
5. Replace and tighten the carbon brush caps.
