⚡ Brushless Motor

The BLACK 53743 uses a brushless electric motor, eliminating conventional carbon brushes.

This design reduces components subject to mechanical wear while providing efficient use of battery power. It is particularly useful for cordless cutting applications where the load changes depending on the size and hardness of the wood.

⭐ 12" / 30 cm Guide Bar

The chainsaw is equipped with a 12-inch (approximately 30 cm) guide bar, making it compact enough for convenient handling while providing useful cutting capacity for everyday jobs.

It is well suited for:

• Cutting and preparing firewood
• Pruning branches and smaller limbs
• Garden and property maintenance
• Cutting suitable timber and wooden material
• General tree-care tasks
• Farm and household work

⚙️ Tool-Free Chain Tensioning

The integrated keyless chain tensioning system allows the operator to adjust chain tension without reaching for a separate wrench for routine adjustments.

Correct chain tension is important for both cutting performance and safe operation, so the chain should always be checked before use.

🔋 2× 21V 4.0Ah Batteries

The package includes two 21V 4.0Ah (4000 mAh) Li-Ion batteries.

Having two batteries provides greater flexibility during longer jobs: one battery can be used while the second is kept ready as a replacement.

Cordless operation is especially convenient in gardens, woodland areas and other locations where mains electricity is unavailable.

⚡ Chain Lubrication System

A built-in 50 ml oil reservoir supplies lubrication for the guide bar and chain.

Correct lubrication helps reduce friction and wear on the cutting components. The oil level, chain condition and guide bar should be checked regularly before and during operation.
