Confirm the model number on the chainsaw matches the manual and your purchase records․
Installing the Guide Bar and Chain
Before installation, ensure the chainsaw is switched off and the chain brake is engaged․ Remove the bar cover by loosening the retaining screws․ Position the guide bar onto the chainsaw body, aligning the bar mounting studs with the holes in the bar․ Secure the bar with the bar nuts, tightening them finger-tight initially․
Next, install the saw chain around the guide bar, ensuring the cutting teeth face in the correct direction – typically towards the base of the bar․ Align the drive links with the sprocket․ Carefully fit the chain into the bar groove․ Once the chain is seated, adjust the bar nuts to provide initial tension․
Refer to the manual for specific diagrams illustrating the correct chain and bar orientation․
Chain Tensioning Procedures
Proper chain tension is crucial for safe and efficient operation․ With the bar mounted, loosen the bar nuts slightly․ Use the tensioning screw, typically located on the chainsaw body, to adjust the chain tension․ Rotate the screw until the chain is snug but can still be pulled around the bar by hand․
A correctly tensioned chain should not sag excessively on the underside of the bar, nor should it bind or feel overly tight․ Refer to the Husqvarna 455 Rancher manual for specific tensioning guidelines․ After adjustment, firmly tighten the bar nuts to secure the bar and maintain tension․
Always check chain tension before each use and after the first few cuts when a new chain is installed․

Operating Instructions
Follow the Husqvarna 455 Rancher manual’s detailed instructions for starting, cutting, and throttle control․ Utilize the chain brake for safety during operation․
Starting the Chainsaw (Cold & Warm Start)
Before starting, ensure the chainsaw is on a flat, clear surface․ For a cold start, engage the choke, set the throttle to the starting position, and firmly hold the saw․ Pull the starter cord with a smooth, deliberate motion until the engine attempts to start․
Disengage the choke once the engine sputters or runs briefly․ Continue pulling the starter cord until the engine runs steadily․ For a warm start, the choke may not be necessary; instead, set the throttle and pull the starter cord directly․
Always maintain a firm grip and be prepared for the saw to kickback․ Refer to the Husqvarna 455 Rancher manual for detailed illustrations and specific instructions related to your model’s carburetor adjustments․
Proper Cutting Techniques
Always maintain a firm grip with both hands while operating the Husqvarna 455 Rancher․ Plan your cuts, ensuring a clear escape path in case of kickback․ Use the correct cutting technique for the type of wood and cut size․ Avoid pinching the bar, which can cause kickback and damage the saw․
Begin with the chain at full speed and apply gentle pressure․ Let the saw do the work; do not force it․ When felling trees, use appropriate notching and back-cutting techniques․ Consult the manual for detailed diagrams illustrating safe felling procedures․
Remember to keep your body positioned to the side of the cutting plane, never directly behind the saw․ Prioritize safety and always wear appropriate personal protective equipment․
Throttle Control and Chain Brake Usage
Understanding throttle control is crucial for safe operation of the Husqvarna 455 Rancher․ Engage the throttle progressively for controlled cutting speed․ Avoid full throttle when starting or performing delicate cuts․ The chain brake is a vital safety feature; always engage it before starting the saw and when transporting it․
Regularly check the chain brake’s functionality as outlined in the manual․ Familiarize yourself with the quick-stop chain brake, designed to halt the chain instantly in emergencies․ Practice activating the chain brake until it becomes second nature․
Never disable or tamper with the chain brake․ Proper use of throttle control and the chain brake significantly reduces the risk of accidents and ensures safe operation․

Maintenance and Servicing
Regular maintenance, including air filter cleaning, spark plug checks, and chain sharpening, is vital for optimal Husqvarna 455 Rancher performance and longevity․
Air Filter Cleaning and Replacement
Maintaining a clean air filter is crucial for the Husqvarna 455 Rancher’s engine health․ A dirty filter restricts airflow, reducing power and increasing fuel consumption․ Regularly inspect the air filter before each use, and clean it more frequently in dusty conditions․
To clean, gently tap the filter to remove loose debris․ For stubborn dirt, wash with warm water and mild soap, ensuring it’s completely dry before reinstalling․ Replace the air filter when it becomes damaged or excessively dirty, as a compromised filter can lead to engine wear․ Husqvarna recommends checking the filter frequently for optimal performance․
Proper filter maintenance ensures efficient engine operation and extends the lifespan of your chainsaw․ Ignoring this step can result in costly repairs and reduced cutting performance․
Spark Plug Inspection and Replacement
Regular spark plug inspection is vital for maintaining optimal engine performance in your Husqvarna 455 Rancher․ A faulty spark plug can cause starting difficulties, reduced power, and increased fuel consumption․ Inspect the plug periodically for signs of fouling, wear, or damage․
To inspect, remove the spark plug and examine the electrode․ A healthy plug should have a tan or light gray color․ Replace the spark plug if it’s blackened, oily, or shows signs of erosion․ Use the correct spark plug specified in your Husqvarna manual for optimal results․
Proper spark plug maintenance ensures reliable starting and efficient engine operation․ Always disconnect the spark plug wire before performing any inspection or replacement to prevent accidental starting․
Chain Sharpening Guide
Maintaining a sharp chain is crucial for safe and efficient cutting with your Husqvarna 455 Rancher․ A dull chain requires more force, increasing the risk of kickback and reducing cutting performance․ Regular sharpening extends chain life and improves overall productivity․
Use a round file of the correct size, guided by a sharpening guide, to maintain the proper cutting angle․ File each tooth consistently, ensuring uniform length and depth․ Pay attention to the depth gauges, filing them down slightly to maintain optimal cutting action․

Sharpening frequently, even a small amount, is better than waiting until the chain is severely dull․ Refer to your Husqvarna manual for detailed instructions and recommended sharpening angles․
Bar Maintenance and Flip Instructions
Proper bar maintenance is vital for the longevity and performance of your Husqvarna 455 Rancher chainsaw․ Regularly inspect the bar for wear, burrs, and damage․ Clean the bar groove to remove sawdust and debris, ensuring smooth chain travel․ Lubricate the bar and chain frequently with bar and chain oil during operation․
Flipping the bar reverses wear patterns, extending its lifespan․ Remove the chain and bar, then flip the bar over and reinstall it․ Ensure the oil holes align correctly for proper lubrication․ Check chain tension after flipping, adjusting as needed․
Refer to your Husqvarna manual for specific instructions and recommended maintenance schedules․ Consistent care will maximize bar life and cutting efficiency․
Fuel System Maintenance (Fuel Mix Ratio)
Maintaining the fuel system of your Husqvarna 455 Rancher is crucial for reliable operation․ Always use a fresh fuel mix of gasoline and two-stroke oil․ The recommended fuel mix ratio is 50:1 (50 parts gasoline to 1 part two-stroke oil)․ Use high-quality, name-brand two-stroke oil specifically designed for air-cooled engines․
Before each use, shake the fuel container thoroughly to ensure proper mixing․ Avoid using fuel mixtures that have been sitting for extended periods, as the oil can separate․ Inspect the fuel filter regularly and replace it if it becomes clogged․ Clean the fuel tank periodically to remove sediment․
