This document is an operator's manual for the Husqvarna 36/41 chainsaw, providing detailed instructions on its safe operation, maintenance, and various cutting techniques.
The chainsaw is designed for two-handed use and is equipped with a two-stroke engine that requires a specific fuel mixture of gasoline and two-stroke oil. It features an automatic chain lubrication system, which necessitates the use of special chain oil with good adhesive characteristics. Users are warned against using waste oil, as it can damage the oil pump, bar, and chain. The manual emphasizes the importance of using chain oil with the correct viscosity for the ambient temperature, especially in cold conditions.
The manual highlights several critical safety precautions. It warns against kickback, which can occur when the guide bar tip touches an object or when the wood pinches the saw chain. To mitigate kickback, users are advised to maintain a firm grip with both hands, keep the cutting area free from obstacles, cut at high engine speeds, and avoid overreaching or cutting above shoulder height. The chainsaw is equipped with a chain brake, designed to stop the chain immediately in the event of kickback. This brake can be manually activated by pushing the front hand guard forward or automatically via an inertia-activated mechanism. Regular daily checks of the chain brake's function are mandatory.
Detailed instructions are provided for starting both cold and warm engines. For a cold start, the chain brake must be disengaged, the ignition switch moved to the left, and the choke control pulled out. The starter handle is then pulled sharply until the engine ignites. For a warm start, the same procedure is followed but without the choke. To stop the engine, the ignition switch is moved to the right. Users are cautioned never to start the saw without the bar, chain, and clutch cover assembled, as this can cause the clutch to come loose and result in personal injuries.
Proper maintenance of the chain and guide bar is crucial for safe and efficient operation. The chain tension must be checked frequently, as a loose chain can jump off the bar, causing injury and damage. The manual describes how to tension the chain using a combination wrench until it fits snugly on the underside of the bar but can still be turned easily by hand. Sharpening instructions are provided, emphasizing the use of specific tools like a round file, file gauge, and flat file to maintain correct cutting angles and depth gauge settings. The depth gauge setting is critical; a too-small setting can make the chain dangerously aggressive, increasing the risk of kickback. The drive sprocket should be changed each time a new chain is fitted to ensure optimal performance and longevity.
The air filter requires daily cleaning, especially in dusty conditions, to prevent carburettor malfunctions, starting problems, reduced engine power, and abnormal fuel consumption. The muffler, which reduces noise and directs exhaust gases, should have its screen cleaned weekly to prevent overheating and damage to the cylinder and piston.
The carburettor has three adjustment possibilities: low speed (L), high speed (H), and idle speed (T). These needles regulate the fuel-air mixture, affecting engine speed and performance. The manual explains that turning the needles clockwise creates a leaner mixture (higher RPMs), while counter-clockwise creates a richer mixture (lower RPMs). The chainsaw is factory-set with a basic carburettor adjustment, which should be maintained for the first five hours of operation. After this "break-in" period, a final adjustment by qualified service personnel is recommended to ensure peak performance and minimal emissions.
The manual advises against cutting in adverse weather conditions and emphasizes the importance of a secure footing and clear work area. It details techniques for felling trees, including notching and making the felling cut, and provides guidance on limbing and cross-cutting logs under various conditions. Users are warned against using the saw to pry or for any unintended purpose. If the saw gets stuck, the engine should be stopped, and the log repositioned using a lever, rather than attempting to pull the saw free.
Essential tools for routine maintenance include a T-wrench for chain tension adjustment, a small screwdriver for carburettor adjustment, and various files and gauges for chain sharpening. The manual also recommends wearing appropriate safety clothing and carrying a first aid kit and forestry tools like wedges, an axe, and a felling lever.
Overall, the manual serves as a comprehensive guide to operating and maintaining the Husqvarna 36/41 chainsaw safely and effectively, stressing the importance of regular checks and adherence to recommended procedures.
