Understanding Your 20 inch poulan pro chainsaw: Power and Performance
When you step up to a saw of this size, you are moving into the realm of heavy-duty property maintenance. The 20 inch poulan pro chainsaw is designed for those who need to tackle larger diameter logs that smaller homeowner saws simply cannot handle. Its 50cc 2-cycle engine provides the necessary torque to pull a long chain through dense hardwoods.
One of the standout features of this model is the OxyPower engine technology. This system offers better fuel efficiency and lower emission levels without sacrificing the “grunt” needed for tough cuts. For the off-grid explorer or homesteader, this means your fuel supply lasts longer during extended clearing sessions.
The 20-inch guide bar allows you to fell medium to large trees with a single pass in many scenarios. This length provides a significant reach, which is helpful when bucking logs on the ground. It reduces the amount of bending you have to do, saving your back during long workdays.
The Benefits of the Pull-Assist Starting System
Starting a large gas-powered saw can often be a physical challenge, especially in cold weather. This model features a SuperClean centrifugal air cleaning system and a professional-style pull-start. The pull-assist mechanism reduces the force needed to engage the engine by up to 30 percent.
For solo travelers or smaller-framed users, this feature is a game-changer. It ensures that you can get the tool running quickly when you encounter a downed tree blocking a remote forest road. Reliability in starting is a core pillar of outdoor safety and efficiency.
Ergonomics and Vibration Dampening
Extended use of a chainsaw can lead to “white finger” or significant hand fatigue due to engine vibrations. Poulan Pro integrates an advanced anti-vibration system into the handle design. This isolates the engine’s movement from your hands and arms.
Good ergonomics allow for more precise cuts and better control over the tool. When you are limbing a tree or performing delicate felling notches, control is your best friend. A steady hand leads to a safer workspace for everyone involved.
Initial Setup and Safety Protocols for First-Time Users
Before you pull the starter cord, you must ensure the machine is assembled and fueled correctly. Most issues with the 20 inch poulan pro chainsaw stem from improper fuel mixtures or incorrect chain tension. Always use a fresh 50:1 ratio of unleaded gasoline and high-quality 2-cycle air-cooled engine oil.
Check the chain tension by pulling the chain away from the guide bar. It should snap back into place but still move freely when pulled by hand (wear gloves!). If the chain is too loose, it can jump off the bar; if it is too tight, it will overheat and damage the engine.
Safety is the most important part of any outdoor task. Never operate a saw without the proper Personal Protective Equipment (PPE). This includes chainsaw chaps, a helmet with a face shield, hearing protection, and steel-toed boots.
Understanding Kickback and the Chain Brake
Kickback occurs when the upper quadrant of the bar nose hits an object, causing the bar to fly upward toward the operator. It is the leading cause of chainsaw injuries. To prevent this, never cut with the tip of the bar and always maintain a firm, two-handed grip.
The 20 inch poulan pro chainsaw comes equipped with an inertia-activated chain brake. If a kickback event occurs, the brake is designed to stop the chain instantly. Always test this brake before you start cutting by pushing the handguard forward to ensure it clicks into place.
Creating a Safe Work Zone
Before you begin felling or bucking, clear the area of trip hazards like loose branches or rocks. Establish a “no-go” zone for bystanders that is at least twice the height of the tree you are cutting. If you are working alone, always let someone know your location and expected return time.
Identify at least two escape paths that lead away from the direction of the fall at a 45-degree angle. Nature is unpredictable, and trees can “chair-back” or split unexpectedly. Having a clear exit strategy is a hallmark of an experienced woodsman.
Operating Techniques: From Bucking to Felling
Once your saw is running and your safety gear is on, it is time to put the 20 inch poulan pro chainsaw to work. For beginners, start with bucking, which is the process of cutting a downed log into smaller sections. Ensure the log is stable and will not roll once the cut is completed.
Use the bucking spikes (the metal teeth near the base of the bar) to pivot the saw through the wood. This provides leverage and reduces the physical effort required to push the saw. Let the weight of the machine and the sharpness of the chain do the work.
When felling a standing tree, the goal is to control exactly where it lands. Start by making a “notch” on the side of the tree facing the direction you want it to fall. This notch should consist of a top diagonal cut and a bottom horizontal cut that meet perfectly.
The Felling Back-Cut
The back-cut is made on the opposite side of the notch, about two inches higher than the notch’s floor. Do not cut all the way through to the notch; leave a strip of wood called the “hinge.” This hinge is what guides the tree safely to the ground.
If the tree begins to lean back on your saw, use a felling wedge. Drive the plastic wedge into the back-cut with a mallet to tip the tree forward. This prevents your bar from getting pinched and stuck in the trunk.
Limbing Safely
Limbing involves removing the branches from a fallen tree. This can be surprisingly dangerous because branches are often under tension. If you cut a “spring pole” (a branch bent under the weight of the tree), it can snap back and strike you.
Always stand on the opposite side of the trunk from the branch you are cutting. This uses the log as a protective barrier between you and the saw. Work from the base of the tree toward the top for the best stability.
Routine Maintenance for Your 20 inch poulan pro chainsaw
A well-maintained tool is a safe tool. To keep your 20 inch poulan pro chainsaw in peak condition, you must perform regular checks. After every few hours of use, remove the side cover and clean out the sawdust and oil gunk that accumulates around the sprocket.
Flip the guide bar regularly to ensure it wears evenly on both sides. This prevents the bar from developing “rails” that can cause the chain to cut at an angle. Use a flat file to remove any burrs that form along the edges of the bar.
The air filter is the lungs of your engine. If it becomes clogged with fine dust, the engine will run hot and lose power. Simply pop the top cover, remove the filter, and wash it in warm soapy water or replace it if it is damaged.
Sharpening the Chain
A dull chain is dangerous because it requires you to apply more pressure, increasing the risk of a slip. You know your chain is dull when it produces fine dust instead of large wood chips. Use a 7/32-inch round file to sharpen the cutters at the correct angle.
Maintain the depth gauges (the little metal fins in front of each cutter) using a flat file and a depth gauge tool. These determine how deep each tooth bites into the wood. If they are too high, the saw won’t cut; if they are too low, the saw will “chatter” and kick.
Managing the Oiling System
The chain needs constant lubrication to prevent friction and heat. Your saw features an automatic oiler that pumps bar and chain oil whenever the chain is spinning. Always refill your oil tank every time you refill your fuel tank.
Check the oil hole on the guide bar to ensure it isn’t plugged with debris. You can test the oiler by holding the nose of the bar near a clean stump and revving the engine. You should see a fine spray of oil appear on the wood surface.
Troubleshooting Common Engine and Chain Issues
Even the best gear can run into hiccups in the field. If your 20 inch poulan pro chainsaw won’t start, the first thing to check is the spark plug. A “fouled” plug covered in black soot or wet fuel will prevent the engine from firing.
Another common issue is a “flooded” engine. This happens when too much fuel enters the combustion chamber. To fix this, turn the switch to off, pull the choke out, and pull the starter cord several times to clear the excess gas.
If the saw starts but dies when you give it gas, you may have a clogged fuel filter or a dirty carburetor. In remote areas, fuel can sometimes sit too long and turn into “varnish,” which blocks the small passages in the engine. Always use a fuel stabilizer if you plan to store the saw for more than 30 days.
Adjusting the Carburetor
High altitudes or extreme temperature changes can affect how your engine runs. There are usually three adjustment screws: Idle (T), Low (L), and High (H). Only adjust these if you are comfortable with small engine mechanics.
The “T” screw adjusts the idle speed. If the chain moves while the saw is idling, the idle is too high. Turn the screw counter-clockwise until the chain stops moving. If you cannot get the saw to run smoothly, it is time to visit a professional service center.
Essential Gear and Accessories for Outdoor Work
To get the most out of your 20 inch poulan pro chainsaw, you need a supporting kit. A “scrench” (a combination screwdriver and wrench) is the most vital tool for adjusting chain tension and changing spark plugs. Keep one in your pocket or attached to the saw’s scabbard.
Invest in a high-quality fuel can that features a “no-spill” nozzle. This prevents environmental contamination and keeps your fuel clean. For those living off-grid, a dedicated storage box for your saw, extra chains, and files will keep everything organized and dry.
Consider carrying a “stump vise” in your truck or RV. This small metal tool hammers into a log and holds the saw bar steady. It makes field sharpening much easier and more accurate than trying to hold the saw between your knees.
Frequently Asked Questions About the 20 inch poulan pro chainsaw
What is the correct fuel mix for this chainsaw?
The engine requires a 50:1 ratio of gasoline to 2-cycle oil. This equates to 2.6 ounces of oil per one gallon of gasoline. Always use fresh, 87-octane (or higher) gasoline and avoid fuels with high ethanol content, as they can damage the engine seals.
Can I put a shorter bar on this 50cc engine?
Yes, you can typically run an 18-inch bar on this powerhead if you prefer a more maneuverable saw for limbing. However, the 20-inch bar is the maximum recommended length to ensure the engine doesn’t overheat under heavy loads.
Why does my chain keep getting loose while I am cutting?
New chains naturally “stretch” during their first few uses as the rivets seat themselves. You may need to tension a new chain several times during the first hour of work. Also, ensure the bar nuts are tightened securely after every adjustment.
How often should I replace the spark plug?
For optimal performance, inspect the spark plug every 20 hours of use. Replace it once a season or if you notice the electrode is worn or heavily carbonized. A fresh plug ensures easier starting and better fuel economy.
Summary and Final Thoughts
Mastering the 20 inch poulan pro chainsaw is a journey that combines mechanical skill with physical awareness. By prioritizing safety, staying on top of routine maintenance, and using the right cutting techniques, you turn a powerful machine into a reliable partner.
