Low-Kickback Chain has met kickback performance require- ments when tested on a representative sam- ple of chain saws below 3.8 cubic inch displacement specified in ANSI B175.1.

S Position of front and rear handlebars, de- signed with distance between handles and “in-line” with each other. The spread and “in- line” position of the hands provided by this design work together to give balance and re- sistance in controlling the pivot of the saw back toward the operator if kickback occurs.

CHAIN BRAKE

SChain Brake, designed to stop the chain in the event of kickback.

WARNING: WE DO NOT REP- RESENT AND YOU SHOULD NOT AS- SUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICK- BACK. Kickback is a lightning fast action which throws the bar and rotating chain back and up toward the operator. Kickback can be caused by allowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain

along the top of the guide bar. This action may push the guide bar rapidly back toward the op- erator. Either of these events may cause you to lose control of the saw which could result in serious injury or even death. DO NOT RELY UPON ANY OF THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK. Reduced--kickback guide bars and low--kickback saw chains reduce the chance and magnitude of kickback and are recommended. Your saw has a low kickback chain and bar as original equipment. Repairs on a chain brake should be made by an autho- rized servicing dealer. Take your unit to the place of purchase if purchased from a servic- ing dealer, or to the nearest authorized master service dealer.

S Tip contact in some cases may cause a lightning fast reverse REACTION, kicking guide bar up and back toward operator.

SPinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator.

SEither of these reactions may cause you to lose control of the saw which could result in serious injury. Do not rely exclusively upon safety devices built into your saw.

WARNING: Computed kickback angle (CKA) listed on your saw and listed in the CKA table below represents angle of kickback your bar and chain combinations will have when tested in accordance with CSA and ANSI standards. When purchasing replacement bar and chain, considerations should be given to the lower CKA values. Lower CKA values represent safer angles to the user, higher values indicate more angle and higher kick energies. Computed angles represented in the non-activated column in- dicate total energy and angle associated without activation of the chain brake during kickback. Activated angle represents chain stopping time relative to activation angle of chain brake and resulting kick angle of saw. In all cases lower CKA values represent a safer operating environment for the user. The following guide bar and chain combina- tions meet kickback requirements of CSA Z62.1, Z62.3, & ANSI B175.1 when used on saws listed in this manual. Use of bar and chain combinations other than those listed is not recommended and may not meet the CKA requirements per standard.

NOTE: If this saw is to be used for commer- cial logging, a chain brake is required and shall not be removed or otherwise disabled to com- ply with Federal OSHA Regulations for Com- mercial Logging.

SAFETY NOTICE: Exposure to

vibrations through prolonged use of gasoline powered hand tools could cause blood vessel or nerve damage in the fingers, hands, and joints of people prone to circulation disorders or abnormal swellings.

3450, 3750 specifications

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.
