The GD40CS18 Overview

Greenworks GD40CS18 is an affordable cordless 40-cm bar chainsaw suitable for cutting small trees or pruning branches.

This design, along with its advanced brushless drive system, ensures powerful yet easy and convenient cutting operation with extreme user convenience and safety.

Some Unique Features Of This Product

  • Drive System: Greenworks GD40CS18 utilizes the advanced brushless motor technology for its drive system. Brushless motors are the hallmark of motor-driven power tools. They afford 30 per cent more power, better energy efficiency; thus, longer run time, zero maintenance, and less weight. This advanced drive option eliminates the use of carbon brushes and the friction produced when they move. Therefore, the tool remains relatively cool throughout its operation and will last longer.

Overall, this drive system delivers chain speeds of 20m/s and a 3/8-inch pitch suitable for light to medium-scale cutting of branches and trunks.

  • Automatic Chain Oiling: All chainsaws require oiling when working. Yet, the lubrication technique differs from brands and products. This tool comes with a see-through calibrated oil tank that allows users to monitor the oil level while the machine is in use. Frequent refilling of the tank is required, but the lubrication process is automatic. Thus, improving its ease of use.
  • Electronic Chain brake: Chain brakes, as the name implies, provide clamping force to halt the chain, and they secure the chain in two conditions. First, when changing position, moving between cuts, or starting a cold saw, all require the tool’s throttle to be partly open.  The second condition is to act as an anti-kickback function to prevent the user from being struck by a running chain.

This chainsaw comes with an advanced and effective braking system- the electronic chain brake that guarantees effective and quick braking action when triggered.

  • Two-Button Safety Control: Chainsaws poses great risks of accidents and severe injuries if not handled carefully. As such, there have been advancements in its design to improve its safety. One such innovation is the two-button safety control. This option lets the device only come on when both buttons are triggered. Hence, reducing the risk of accidental starting of the tool.
  • Ergonomic Grip Handles: The operator’s overall cutting success and safety when using a chainsaw significantly depends on its handling. In this wise, the tool features the ergonomic rubberized soft handle for comfortable but firm grip and to minimize the shock and vibration from the device from being transferred to the operator.
  • Design: This tool comes with a compact, lightweight design, only weighing about 3.8kg but perfectly balanced for easy and convenient use.
