Chainsaw Proline PROBUILDER 51800 — rear-handle model with cutting box

Proline PROBUILDER 51800 is a rear-handle chainsaw designed for cutting tasks in domestic and light professional environments. The rear-handle configuration provides balanced control for felling, limbing and general wood cutting. The integrated cutting box encloses the chain and bar assembly to simplify handling and protect the cutting components during storage and transport.

Advantages

This rear-handle model offers straightforward handling with a grip designed for controlled two-handed operation. The cutting box reduces exposure of the chain and bar, making maintenance and transport safer and neater. The design supports routine serviceability so users can perform chain tensioning and basic upkeep without specialised tools.

Suitable for

• Felling small to medium trees
• Limbing and pruning operations
• Cutting firewood and general yard maintenance
• Homeowners and light-duty professional users

Key specifications

• Rear-handle configuration for two-handed control and maneuverability
• Integrated cutting box enclosing chain and guide bar for safer handling
• Intended for domestic and light professional cutting tasks
• Suitable for use with standard chainsaw bars and cutting chains of corresponding size

How to use

Before starting, check chain tension, fuel or power source, and the general condition of the guide bar and chain. Hold the saw with both hands using the rear handle and front support, maintain a stable stance and clear the work area of obstacles. For felling, plan the cut and escape route; for limbing and cutting firewood, secure the log to prevent rolling. Follow the manufacturer’s routine maintenance intervals for chain sharpening, tension adjustment and air filter checks to ensure consistent performance.

Usage recommendations

Use appropriate personal protective equipment (helmet with face shield, hearing protection, gloves, cut-resistant trousers and boots). Operate the chainsaw on stable ground, avoid cutting above shoulder height, and allow the engine or motor to come to operating speed before engaging the chain. Regularly inspect the cutting box and chain condition and replace worn components as needed.
