The OT8C104S Mini Electric Chain Saw is a thoughtfully engineered solution for those seeking both portability and performance in pruning and cutting tasks. Designed with user convenience in mind, this tool strikes a balance between lightweight handling and impressive cutting capability, making it well-suited for both professional landscapers and DIY garden enthusiasts.

Compact and Powerful Performance
At the core of the OT8C104S is a high-efficiency brushless DC motor powered by a 20V battery pack. This advanced motor design delivers stable torque with reduced noise and vibration, enhancing comfort during prolonged use. The cordless structure ensures mobility, allowing users to tackle tree branches and shrubs in tight or remote areas without the restriction of power cords.

The tool supports both 2Ah and 4Ah battery packs with a 20V series connection, allowing flexible runtime depending on the task. With a full charge using the 4Ah battery, users can expect to cut up to 75 pieces of 120mm diameter wood or 38 pieces of 140–180mm diameter wood, making it a reliable performer for a wide range of applications.

Flexible Bar and Chain System
To accommodate different cutting requirements, the OT8C104S comes equipped with two interchangeable bar and chain options — 6-inch (150mm) and 8-inch (200mm) setups. This allows users to easily switch between precision pruning and slightly larger cutting jobs. The chain runs at a speed of 8 meters per second, supported by a chain brand/model 030 with 0.043-inch gauge and 39 links, offering smooth and efficient cutting results.

The chain tensioning system is fully tool-free, utilizing an SDS (self-tightening) mechanism for fast, convenient adjustments on the go. Whether you’re in the workshop or out in the field, chain maintenance is straightforward and efficient.

User-Centric Safety and Design
Safety is a key focus in the design of the OT8C104S. This model includes both chain guard and hand guard protection, effectively minimizing user exposure to debris and chain movement. The integrated brake function provides added control and responsiveness, helping to reduce risks during sudden kickbacks or operational errors.

Additionally, the saw is designed for ambidextrous use, enabling both left- and right-handed operation comfortably. Its balanced structure and ergonomic handle allow extended cutting sessions with reduced fatigue.

Automatic Lubrication and Pole Extension
An automatic oiling system ensures continuous lubrication of the chain, reducing wear and maintaining performance. This feature extends the tool’s lifespan and reduces the need for frequent maintenance.

For overhead or hard-to-reach branches, the OT8C104S can be paired with an extension pole assembly, extending the reach to 3 meters. This makes it ideal for trimming higher limbs without requiring a ladder, thereby improving safety and convenience.

Certified for Peace of Mind
The OT8C104S is manufactured to high quality and safety standards, with certifications including EMC, GS, and RoHS. These approvals reflect our commitment to environmentally responsible design and operational safety.
