To obtain the best cutting results, the mower housing should be adjusted so that the front is approximately 1/8" to 1/2" lower than the rear when the mower is in its highest position.

Check adjustment on right side of tractor. Measure distance “D” directly in front and behind the mandrel at bottom edge of mower housing as shown.

•Before making any necessary adjustments, check that both front links are equal in length.

•If links are not equal in length, adjust one link to same length as other link.

•To lower front of mower loosen nut “E” on both front links an equal number of turns.

•When distance “D” is 1/8" to 1/2" lower at front than rear, tighten nuts “F” against trunnion on both front links.

•To raise front of mower, loosen nut “F” from trunnion on both front links. Tighten nut “E” on both front links an equal number of turns. The two front links must remain equal in length.

•When distance “D” is 1/8" to 1/2" lower at front than rear, tighten nut “F” against trunnion on both front links.

433401 specifications

The Poulan 433401 is a remarkable chainsaw that embodies a blend of power, efficiency, and user-friendly design. Ideal for both professionals and DIY enthusiasts, this model is thoughtfully engineered to handle a variety of cutting tasks, from felling trees to pruning shrubs.

One of the most notable features of the Poulan 433401 is its powerful engine. Equipped with a 33cc two-stroke engine, it delivers ample power while maintaining a lightweight build, which is critical for maneuverability during extended usage. The engine's design allows for efficient fuel consumption, enabling users to maximize their cutting time without frequent refueling. This is particularly useful for those who take on larger jobs or require extended operational periods.

The chainsaw boasts a 16-inch guide bar, making it suitable for a range of cutting applications. The length strikes a balance between efficient cutting and ease of control, making it perfect for both seasoned users and those new to chainsaw operation. The Oregon chain enhances cutting performance, providing smooth and reliable operation while ensuring a clean cut.

One of the standout technologies incorporated into the Poulan 433401 is its automatic oiling system. This essential feature ensures that the chain remains adequately lubricated during operation, reducing friction and wear.

Safety features are paramount in the design of the Poulan 433401. It includes a chain brake designed to stop the chain in an event of kickback, which is a common risk when using chainsaws. Additionally, the front and rear handles are ergonomically designed, providing a comfortable grip and reducing user fatigue. This attention to ergonomics helps improve precision and control, particularly during prolonged use.

The Poulan 433401 is also relatively easy to start, thanks to its spring-assisted starter mechanism and purge bulb feature. This makes it accessible to users of all skill levels, eliminating the frustrations often associated with starting smaller engine chainsaws.

Overall, the Poulan 433401 combines power, versatility, and safety. Its innovative design and user-centric features make it a reliable tool for various cutting tasks, setting it apart as a favorable choice in the chainsaw market. Whether for forestry professionals or homeowners looking to maintain their landscapes, the Poulan 433401 stands out as a valuable asset.
