MAINTENANCE

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

1Air intake on the starter.

2Air guide plate.

3Fins on the flywheel.

4Cooling fins on the cylinder.

5Cylinder cover (directs cold air over the cylinder).

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.

Note! The cooling system on a chain saw with catalytic converter must be cleaned daily. This is particularly important on chain saws with catalytic converters, because the higher exhaust temperature requires efficient cooling of the engine and the catalytic converter unit.

”Air Injection” centrifugal cleaning

Centrifugal cleaning means the following: All air to the carburetor passes through the starter. Dirt and dust is pushed out by the cooling fan.

H

IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the fins on the flywheel, the space around the flywheel, inlet pipe and carburetor compartment.

Winter use

Running problems can occur when using the machine in the cold and snowy conditions caused by:

•Too low engine temperature.

•Icing of the air filter and carburetor. Special measures are therefore often required:

•Partly mask the air inlet on the starter to increase the working temperature of the engine.

Temperature 0°C (32°F) or colder:

The cylinder cover is designed so it can be adjusted for running in cold weather. Twist the winter flap so that preheated air from the cylinder can pass into the carburetor space preventing icing of the air filter, etc.

For temperatures below -5°C (23°F) and/or in snow conditions there is also:

•a special cover (A) for the starter housing

•a winter plug (B) for the air nozzle that is fitted as shown.

H

H

These reduce the flow of cooling air and prevent large amounts of snow from being sucked into the carburetor space.

CAUTION! When the winter plug is fitted the winter flap must be open!

IMPORTANT! If the temperature rises above -5°C (23°F) or 0°C (32°F) respectively the machine MUST be restored to its normal set-up. Otherwise there is a risk of overheating, which can cause severe engine damage.

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.
