The GT-770 Petrol Power Cutter is a versatile and high-performance cutting tool designed for various heavy-duty tasks, including concrete, stone, and metal cutting. Here are the key technical aspects and features:

Key Features:

1. Engine & Power:

   • Powered by a 2-stroke petrol engine, typically in the range of 70-80cc displacement.
   • High power output, usually around 5-6 HP (horsepower), providing enough torque for tough cutting applications.
   • Longer operational life thanks to a reliable, efficient engine design.

2. Cutting Capacity:

   • Maximum cutting depth generally between 120-140 mm (depending on the blade size).
   • Capable of using diamond blades, abrasive blades, or carbide blades to handle different materials, such as reinforced concrete, brick, stone, and asphalt.
   • A high-speed blade rotation, typically around 5000-6000 RPM, ensures clean and fast cuts.

3. Blade Size:

   • Typically equipped with a 12-inch (300mm) cutting blade as standard, but may support larger sizes depending on the model.
   • Universal blade compatibility, making it easy to switch blades for different materials or cutting needs.

4. Air Filtration System:

   • Features an advanced air filtration system designed to extend the engine’s life by preventing dust and debris from clogging internal components.
   • Dual-stage air filtration ensures cleaner air intake, reducing wear and tear on the engine.

5. Ergonomics & Handling:

   • Comfortable and vibration-reducing handle design to improve user control and reduce operator fatigue during extended use.
   • Adjustable handles for better ergonomics and to suit various cutting positions, especially for vertical or angled cuts.
   • Low vibration technology for smoother operation and less strain on the operator.

6. Easy Start Mechanism:

   • Spring-assisted recoil starter makes starting easier and quicker.
   • Equipped with a primer pump for easy fueling, ensuring reliable starts in various weather conditions.

7. Water Kit:

   • Integrated water attachment (or available as an accessory) for wet cutting, minimizing dust and extending blade life while maintaining better visibility during operation.

8. Safety Features:

   • Blade guard provides extra protection during operation.
   • Overload protection system that prevents engine damage by monitoring operational load and automatically adjusting.

9. Portability:

   • Lightweight design, typically weighing around 9-10 kg (without blade), making it relatively easy to transport and maneuver in tight spaces.
   • A robust frame and design ensure durability and can withstand the rigors of demanding cutting jobs.

Background & Usage:

• Applications: The GT-770 is primarily used in construction, demolition, roadwork, and renovation projects where fast and clean cutting of hard materials like concrete, brick, stone, and metal is required.
• Durability: Built to handle tough conditions, these power cutters are engineered to withstand high operational stress, ensuring reliability for both professional and industrial use.
• Maintenance: Regular maintenance includes checking the air filter, spark plug, and fuel system, along with blade replacement, to ensure optimal performance and longevity.

The GT-770 is an essential tool for contractors, builders, and operators working in challenging environments where high-quality, durable cutting performance is paramount.
