These steps are essential for those operating this type of equipment.
1. Chain Identification
Proper chain identification is a prerequisite for any replacement procedure on a Husqvarna chainsaw. Selection of a compatible chain ensures safe and efficient operation. The following facets address the key considerations for accurate chain identification.
-
Chain Pitch
Chain pitch, the distance between three consecutive rivets divided by two, determines compatibility with the chainsaw’s sprocket and bar. An incorrect pitch can result in improper meshing, leading to chain slippage or damage to the saw. Measurement tools are used to precisely determine the pitch.
-
Chain Gauge
Chain gauge refers to the thickness of the drive links, the parts of the chain that fit into the guide bar groove. A mismatch in gauge can prevent the chain from properly seating on the bar, causing instability and potential kickback. Calipers are commonly used to verify gauge.
-
Drive Link Count
The number of drive links directly corresponds to the length of the chain required for a specific bar. An incorrect drive link count results in a chain that is either too short to fit or too long to maintain proper tension. Counting the drive links is a fundamental step in chain identification.
-
Chain Type
Different chain types, such as full chisel, semi-chisel, or low-kickback, are designed for specific cutting applications. Selecting the appropriate chain type ensures optimal cutting performance and safety. Full chisel chains offer aggressive cutting, while low-kickback chains prioritize user safety.
The parameters above are critical in chain selection. Failure to consider these aspects during the procurement of a replacement chain will compromise the performance and safety of the chainsaw.
2. Tension Adjustment
Tension adjustment directly influences the performance and longevity of a newly installed chain. Improper tension can lead to several adverse effects. A chain lacking sufficient tension is prone to derailment from the guide bar, potentially causing damage to the saw components or injury to the operator. Conversely, excessive tension increases friction, resulting in accelerated wear on both the chain and the guide bar. Furthermore, an overtightened chain requires more power to drive, reducing cutting efficiency and potentially overloading the engine. Correct chain tension ensures the chain sits properly in the guide bar groove, providing smooth and efficient cutting action. Example: a chain that sags noticeably on the underside of the bar indicates insufficient tension. Proper tension is achieved when the chain can be pulled slightly away from the bar but snaps back readily.
The practical application of proper tension adjustment involves a systematic approach. After installing a new chain, the adjustment screw on the chainsaw should be manipulated to achieve the specified tension. Regular checks during operation are essential, as the chain will stretch during initial use, requiring readjustment. Environmental factors, such as temperature, also affect tension, necessitating adjustments in different conditions. Chainsaw manuals provide precise guidelines for appropriate tension levels based on chain type and operating conditions. Ignoring these guidelines can lead to premature chain failure, increased fuel consumption, and elevated risk of kickback.
In summary, tension adjustment is an indispensable step in the chain replacement process. It directly impacts cutting performance, chain lifespan, and operator safety. Mastering this skill requires attention to detail and adherence to manufacturer recommendations. Challenges arise from variations in chain types and environmental conditions, highlighting the need for continuous monitoring and adaptation of tension levels. Understanding tension adjustment contributes significantly to realizing the full potential of a Husqvarna chainsaw after a chain replacement.
