Such data is essential for several reasons. It allows potential buyers to compare different models and select the equipment that best suits their needs. This information also aids in maintenance and repair, as it specifies the correct parts and procedures. Furthermore, it provides a historical record of the tool’s design and capabilities within the context of chainsaw development.
The following discussion will delve into the specific engine details, physical dimensions, and operational capacities, providing a more complete understanding of this particular model.
1. Engine Displacement
Engine displacement, a key specification, directly defines the cylinder volume swept by the pistons during a single engine cycle. Within the context of this particular chainsaw model, engine displacement dictates the potential force generated, which in turn influences the tool’s cutting power. A larger displacement typically translates to greater torque, enabling the saw to tackle denser wood and larger diameter trees more effectively. The engine displacement value is a critical determinant when assessing suitability for heavy-duty tasks.
For example, a saw with a smaller displacement might struggle when felling a mature oak tree, experiencing significant bogging down and reduced cutting speed. Conversely, a higher displacement engine, as specified, would provide the necessary power to maintain consistent cutting performance under load. Furthermore, understanding the engine displacement is critical for proper fuel mixture calculations and maintenance procedures. Deviation from recommended fuel ratios can negatively impact engine performance and longevity.
In summary, engine displacement is an indispensable element, directly impacting cutting capability and influencing operational efficiency. Precise knowledge of this specification is vital for both users and maintenance personnel to ensure optimal performance and prolonged equipment lifespan. The specification’s implications extend from selecting the right tool for the job to performing necessary maintenance procedures with accuracy.
2. Power Output
Power output, a critical component of the specifications, defines the rate at which work can be performed. In the context of this particular chainsaw model, it dictates the efficiency and speed with which the tool can cut through various types of wood. Higher power output generally correlates with faster cutting times and the ability to handle more demanding tasks. A thorough understanding of the power output is therefore essential for assessing the tool’s suitability for specific applications.

Measurement and Units
Power output is commonly measured in horsepower (hp) or kilowatts (kW). This measurement represents the maximum energy the engine can deliver over a specific period. For example, a rating of 3.6 hp indicates the engine’s capacity to perform a substantial amount of work, translating into quicker and more efficient cutting. Failure to consider this rating could lead to selecting a saw inadequate for intended use.
-
Impact on Cutting Performance
A higher power output directly contributes to improved cutting performance, particularly when processing dense or hardwood materials. Insufficient power results in slower cutting speeds, increased strain on the engine, and potentially reduced lifespan of the tool. Conversely, adequate power ensures consistent performance and reduces the risk of damaging the engine under heavy loads. Real-world scenarios, such as felling large trees, demand substantial power output to maintain efficiency.
-
Fuel Consumption Correlation
While higher power output provides performance benefits, it is often correlated with increased fuel consumption. Efficient engine design aims to maximize power while minimizing fuel usage, but a general relationship exists. Users must consider the trade-off between power and fuel efficiency when selecting the appropriate model. For instance, prolonged use at maximum power will inevitably lead to greater fuel expenditure compared to operating at lower power levels.
-
Engine Durability and Longevity
Operating a chainsaw at its maximum power output for extended periods can place significant stress on the engine components, potentially reducing its lifespan. Understanding the power output specification helps users to operate the tool within its design limits, promoting engine durability and longevity. Regular maintenance, coupled with responsible usage, is critical for preserving optimal performance over time. Ignoring these factors can lead to premature wear and costly repairs.
The interrelated aspects of measurement units, cutting performance, fuel consumption, and engine longevity underscore the importance of considering power output within the overall specifications. This parameter has far-reaching implications for operational effectiveness and maintenance requirements, making its comprehension essential for users. Selecting the correct model necessitates a balance between power and other factors to ensure optimal performance and cost-effectiveness in the long run.
3. Bar Length
Bar length, a key dimension within the specifications, directly influences the cutting capacity and operational characteristics of the chainsaw. This measurement determines the maximum diameter of wood the saw can effectively process in a single pass, impacting its suitability for diverse applications.
-
Maximum Cutting Diameter
The bar length dictates the largest diameter tree or log that can be safely and efficiently cut. A longer bar permits cutting through thicker materials, whereas a shorter bar is better suited for smaller tasks and improved maneuverability. Selecting an appropriate bar length prevents overstressing the engine and chain, ensuring operator safety. For example, attempting to fell a tree exceeding the bar’s cutting capacity can lead to kickback or equipment damage. The specifications provide critical information to match bar length to expected workloads.
-
Chain Speed and Efficiency
Bar length affects chain speed, impacting the overall cutting efficiency. A longer bar requires more power to drive the chain at an optimal speed. This can strain the engine if the power output is insufficient, potentially leading to reduced cutting speed and increased wear on the chain. Ensuring the bar length is well-matched to the engine’s power is essential for maintaining efficiency. Improper matching may require more frequent chain sharpening or even premature engine failure.
-
Saw Weight and Balance
The bar length contributes significantly to the saw’s overall weight and balance, influencing operator fatigue and control. A longer bar adds weight to the front of the saw, potentially making it more difficult to handle, particularly for extended periods. Choosing a shorter bar can improve balance and reduce fatigue but might limit the tool’s cutting capacity. Therefore, the specifications should be reviewed to find a compromise between cutting capabilities and ease of handling.
-
Types of Cutting Tasks
The intended cutting tasks significantly impact the selection of an appropriate bar length. For limbing and pruning, a shorter bar offers improved maneuverability and precision. For felling larger trees, a longer bar is necessary to reach the center of the trunk. The bar length specification should align with the anticipated tasks to ensure optimal performance and operator safety. Selecting a bar length unsuited for the task will impair efficiency and potentially pose a safety risk.
The interrelationship between maximum cutting diameter, chain speed, saw weight, and task appropriateness underscores the importance of the bar length specification. It directly influences the performance, safety, and usability. Careful consideration of these facets enables users to select a chainsaw configuration that aligns with their needs, ensuring efficiency and minimizing risk. Bar length, therefore, plays a critical role in determining the overall effectiveness of the tool.
