ASSEMBLY

Fitting the bar and chain

WARNING! Always wear gloves, when

!working with the chain, in order to protect your hands from injury.

Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle.

Remove the bar nuts and remove the clutch cover (chain brake). Take off the transportation ring (A).

Fit the bar over the bar bolts. Place the bar in its rearmost position. Place the chain over the drive sprocket locate it in the groove on the bar. Begin on the top edge of the bar.

Make sure that the edges of the cutting links are facing forward on the top edge of the bar.

Fit the clutch cover and locate the chain adjuster pin in the hole in the bar. Check that the drive links of the chain fit correctly over the drive sprocket and that the chain is correctly located in the groove in the bar. Tighten the bar nuts finger tight.

Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. See instructions under the heading Tensioning the chain.

The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combination spanner.

When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life.

Note: If clutch cover is difficult to remove, replace bar nuts, engage brake and rerelease (an audible click will be heard if released properly).

Jonsered CS 2141S, CS 2145S manual Assembly, Fitting the bar and chain

CS 2145S, CS 2141S specifications

The Jonsered CS 2141S and CS 2145S chainsaws are powerful tools designed for both professional and avid hobbyist woodworkers. Known for their robust construction and efficient performance, these chainsaws embody reliability and advanced technology, making them ideal for a variety of cutting tasks.

One of the standout features of the Jonsered CS 2141S and CS 2145S is their powerful engines. The CS 2141S is equipped with a 40.9cc engine, while the CS 2145S boasts a slightly more powerful 45.7cc engine. This difference in engine size translates to enhanced cutting performance, allowing users to tackle larger logs and more demanding jobs with ease. Both models deliver excellent power-to-weight ratios, ensuring that users can work for extended periods without excessive fatigue.

These models also incorporate advanced technologies that elevate their functionality. One notable innovation is the X-Torq engine, which reduces fuel consumption and emissions. This is particularly beneficial for environmentally conscious users, as it helps lessen the ecological footprint without compromising on power or performance. Additionally, the effective anti-vibration system minimizes the impact of vibrations on the user, enhancing comfort and control during operation.

Another key characteristic of the CS 2141S and CS 2145S is their ease of use and maintenance. The Quick Release Air Filtration system allows for efficient cleaning and replacement, ensuring that the engine performs at its best. Furthermore, the chain brake feature provides added safety by automatically stopping the chain in the event of kickback, making these chainsaws safer to operate.

Both models are designed for versatility, featuring adjustable oil pumps that allow users to regulate the flow of bar and chain oil for improved lubrication and extended chain life. The ergonomically designed handles offer optimal grip and control, which is essential for precision cutting.

In summary, the Jonsered CS 2141S and CS 2145S chainsaws are powerful and efficient tools equipped with advanced technologies that promote ease of use, safety, and environmental sustainability. Whether for professional forestry work or home woodcutting projects, these models are reliable choices that deliver outstanding performance and durability.
