This document is an operator's manual for the Husqvarna 120 Mark II chainsaw, providing comprehensive instructions for its safe operation, assembly, maintenance, and transportation.
The chainsaw is designed for cutting wood, including felling trees, limbing, and bucking logs. It is a two-cycle engine product that requires a specific mixture of gasoline and two-cycle engine oil for proper function. The product is equipped with various safety features and protective devices to minimize the risk of injury during operation.
The Husqvarna 120 Mark II is a gasoline-powered chainsaw, primarily used for cutting wood. Its core function involves a saw chain that rotates around a guide bar, driven by a two-cycle engine. The saw chain features cutters designed to efficiently cut through wood. The product includes a starter handle for engine ignition, a throttle trigger for controlling engine speed, and a stop switch for immediate engine shutdown. A chain brake and front hand guard are integrated to enhance safety by stopping the saw chain in case of kickback or other hazards. The chainsaw also features a spiked bumper, which aids in stabilizing the saw against the wood during cutting, acting as a pivot point. An automatic lubrication system ensures that the saw chain and guide bar receive sufficient oil during operation, which is crucial for performance and longevity.
The manual details the correct procedures for starting both cold and warm engines, as well as addressing situations where the fuel might be too hot. For a cold start, the operator needs to engage the chain brake, pull out the choke control, push the air purge bulb multiple times, and then pull the starter rope handle with force until the engine starts or tries to start. Once the engine runs, the choke control is moved to the half-choke position, and the engine is allowed to run for a short period before disengaging the chain brake. For a warm start, the process is similar but typically requires fewer pulls of the starter rope.
The manual emphasizes the importance of proper handling, requiring the operator to hold the chainsaw with both hands—the left hand on the front handle and the right hand on the rear handle—and to keep the product on the right side of the body. It explicitly warns against one-handed operation due to the risk of serious injury. When felling trees, the manual instructs on creating a notch and a felling back cut to control the direction of the fall, and advises on planning a clear retreat path. For limbing, it suggests using larger limbs to support the log off the ground. When bucking logs, the operator is guided on making cuts from the top (overbucking) or bottom (underbucking) depending on how the log is supported, and to avoid letting the saw chain touch the ground. The spiked bumper is a key feature for controlled cutting, allowing the operator to pivot the chainsaw against the wood for precise cuts.
The manual outlines a comprehensive maintenance schedule, categorized into daily, weekly, monthly, and intermittent tasks, to ensure the product's safe and efficient operation.
The manual provides detailed instructions for specific maintenance tasks, such as cleaning the spark plug, air filter, and spark arrester screen. It also includes instructions for adjusting the idle speed and sharpening the saw chain, emphasizing the importance of correct filing angles and depth gauge settings for optimal cutting performance and safety. The document also covers procedures for resetting the chain brake if it is accidentally locked during clutch cover removal.
