Engineered for demanding landscaping, arboriculture, and property maintenance professionals, the OT8C105S Cordless Brushless Chain Saw represents a significant advancement in portable, powerful, and user-focused cutting technology. Leveraging a sophisticated 2X20V battery platform and brushless motor innovation, this saw is crafted to deliver robust performance, extended runtime, and enhanced durability, setting a new standard for cordless chainsaw capability.

1. Uncompromised Power & Endurance with the 2X20V Series System:
The core of the OT8C105S's impressive performance lies in its unique 40V-equivalent power system. By utilizing two high-capacity 20V 4.0Ah Lithium-Ion battery packs connected in series, the saw achieves the operational voltage necessary for tackling demanding cutting tasks while maintaining the ergonomic and logistical benefits of the 20V platform. This intelligent configuration translates into substantial cutting power capable of handling limbs and logs up to 16 inches (406mm) in diameter. Combined with the efficiency of the brushless motor, this system facilitates extended runtime, demonstrated by the capability to make approximately 110 cuts through 120mm of wood on a single charge cycle. The inclusion of a low-voltage indicator provides clear communication, allowing users to manage battery usage effectively and plan recharges without unexpected power loss.

2. Advanced Brushless Motor & Drive System:
At the heart of the OT8C105S is a high-performance brushless DC motor, renowned for its efficiency, durability, and power delivery compared to traditional brushed motors. This motor design incorporates high-quality copper wire windings, enhancing conductivity for stronger torque output and faster chain speeds reaching 16 meters per second. A critical advantage is the motor's efficient heat dissipation system. By significantly reducing operational heat build-up, the saw maintains consistent power delivery during prolonged use, minimizing the risk of motor overload and contributing directly to the prevention of jamming. This results in smooth, fast cutting performance that professionals can rely on for continuous operation.

3. Engineered for Productivity & User Convenience:
Understanding the demands of professional use, the OT8C105S integrates several features designed to maximize productivity and minimize downtime:

Automatic Chain Oiling System: This essential feature continuously lubricates the chain and bar during operation. Consistent lubrication reduces friction significantly, which not only protects the chain and bar from premature wear but also ensures smoother cutting action and directly contributes to extending the overall service life of your saw chain.

Tool-Free SDS Chain Tensioning: Adjusting chain tension is quick, simple, and requires no tools. This SDS (Simple Tensioning System) allows operators to maintain chain tension effortlessly in the field, ensuring peak cutting efficiency and safety without interrupting workflow.

Optimized Ergonomics: A soft grip rear handle enhances operator comfort and control, reducing fatigue during extended cutting sessions and improving overall handling precision.

4. Comprehensive Safety & Protection Systems:
Safety and equipment protection are paramount in professional power tool design. The OT8C105S incorporates multiple layers of safeguards:

Anti Self-Locking Switch: This critical safety feature prevents accidental activation, ensuring the saw only operates when intentionally engaged by the user.

Ultra-Fast Emergency Brake: Engineered for immediate response, the brake system activates within an impressive 0.15 seconds upon kickback detection or when the hand guard is triggered, providing a vital layer of operator protection.

Brake Board Warning Indicator: Offers clear visual feedback on the status of the critical brake system, enhancing user confidence.

Multi-Circuit Electronic Protection: The saw and its battery system incorporate sophisticated protection against potential hazards:

Over-Current Protection: Safeguards the motor and electronics from damage due to excessive current draw.

Thermal Protection: Monitors temperature to prevent overheating of the motor and control board.

Overcharging Protection: Integrated within the battery management system to ensure safe charging cycles for the 20V/4.0Ah packs using the included 21.5V/2A charger.

5. Robust Construction & Global Compliance:
Built to withstand the rigors of professional use, the main body of the OT8C105S utilizes high-strength PA6 polymer, offering a balance of durability, impact resistance, and lighter weight. The saw comes equipped with a quality Chinese chain (3/8" pitch, 0.043" or 0.050" gauge) compatible with 355mm (14") or 406mm (16") bars. Furthermore, adherence to stringent international safety and environmental standards is confirmed through GS (Tested Safety), EMC (Electromagnetic Compatibility), and RoHS (Restriction of Hazardous Substances) certifications, assuring global market suitability and responsible manufacturing.

The OT8C105S 2X20V 4.0Ah Brushless DC Side Motor Electric Chain Saw is more than just a tool; it's a comprehensive solution designed for the professional user who demands power without the cord, reliability without compromise, and features that enhance both productivity and safety. Its advanced series battery system, efficient brushless motor, automated lubrication, tool-free maintenance, and multi-layered protection deliver a potent combination for tackling demanding cutting tasks efficiently and dependably.
