Poulan 3450, 3750 Fueling Engine, BAR and Chain Lubrication, Important Points to Remember

Page 9

WARNING: Remove fuel cap slowly when refueling.

FUELING ENGINE

This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil. We recommend Poulan or Poulan ProR brand oil. If you do not use this oil, use a good quality 2-cycle air-cooled oil designed to be mixed at a ratio of 40:1. A 40:1 ratio is obtained by mixing 3.2 onces of oil with 1 gallon of unleaded gasoline. Included with this saw is a 3.2 ounce container of Poulan/Weed Eater brand oil. Pour the entire contents of this container into 1 gallon of gasoline to achieve the proper fuel mixture.

DO NOT USE automotive or boat oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Always read and follow the safety rules listed under HANDLE FUEL WITH CAUTION.

BAR AND CHAIN LUBRICATION

The bar and chain require continuous lubrica- tion. Lubrication is provided by the automatic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/or discolor- ation of the bar.

In freezing weather oil will thicken, making it necessary to thin bar and chain oil with a small amount (5 to 10%) of #1 Diesel Fuel or kerosene. Bar and chain oil must be free flowing for the oil system to pump enough oil for adequate lubrication.

Genuine PoulanR bar and chain oil is recommended to protect your unit against excessive wear from heat and friction. PoulanR oil resists high temperature thinning. If PoulanR bar and chain oil is not available, use a good grade SAE 30 oil.

SNever use waste oil for bar and chain lubri-

cation.

SAlways stop the engine before removing the oil cap.

IMPORTANT

Experience indicates that alcohol--blended fuels (called gasohol or using ethanol or meth- anol) can attract moisture which leads to sepa- ration and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine prob- lems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See STORAGE section for addi- tional information.

WARNING: The chain must not move when the engine runs at idle speed. If the chain moves at idle speed refer to CAR- BURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. A hot muffler can cause serious burns.

To stop the engine move the ON/STOP switch to the STOP position.

To start the engine hold the saw firmly on the ground as illustrated. Make sure the chain is free to turn without contacting any object.

Use only 15”--18” of rope per pull.

IMPORTANT POINTS TO REMEMBER

When pulling the starter rope, do not use the full extent of the rope as this can cause the rope to break. Do not let starter rope snap back. Hold the handle and let the rope rewind slowly.

For cold weather starting, start the unit at FULL CHOKE; allow the engine to warm up before squeezing the throttle trigger.

NOTE: Do not cut material with the choke/ fast idle lever at the FULL CHOKE position.

The Poulan 3450 and 3750 chainsaws are notable models in the Poulan lineup, designed for both homeowner and light professional use. These chainsaws are recognized for their reliability, ease of use, and efficient performance in cutting tasks, making them a popular choice among users.

One of the defining features of the Poulan 3450 is its lightweight design, weighing in at approximately 10 pounds. This makes it easy to handle for extended periods without causing significant fatigue. The 3450 is equipped with a 16-inch bar, suitable for small to medium-sized cutting jobs, whether pruning trees or cutting firewood. It is powered by a 34 cc engine that provides adequate power for these tasks while maintaining a balance between performance and fuel efficiency.

The Poulan 3750 model offers a bit more power with its 37 cc engine. This model also features a 16-inch bar, but the additional engine capacity allows for better performance in more demanding cutting conditions. The 3750’s enhanced power makes it an excellent choice for users who require a bit more muscle for larger jobs, while still being manageable for the average homeowner.

Both models incorporate Poulan's patented Easy Start technology, which significantly reduces the effort needed to start the engine. This technology is particularly beneficial for less experienced users, as it requires less pull force compared to traditional chainsaw designs.

Another significant feature of the Poulan chainsaws is their automatic chain oiler that ensures the chain remains lubricated during operation. This helps to prolong the life of the chain and bar, reducing wear and enhancing cutting efficiency. The adjustable oiler also allows users to customize the oil flow based on their cutting applications.

In terms of safety, the Poulan 3450 and 3750 come equipped with a chain brake system that quickly stops the chain in the event of kickback, providing an additional layer of protection for the operator.

With their combination of power, portability, and ease of use, the Poulan 3450 and 3750 chainsaws present an excellent value for homeowners looking for reliable and efficient tools for their outdoor tasks. These models highlight Poulan's commitment to innovation and user-friendly designs, making them a smart choice for anyone needing a dependable chainsaw.
