MAINTENANCE

Needle bearing lubrication

The clutch drum is fitted with one of the following drive sprockets:

•A Spur sprocket (the chain sprocket is welded on the drum)

•B Rim sprocket (replaceable)

Both versions have a needle bearing on the drive shaft, which has to be greased regularly (once a week).

CAUTION! Use only high quality bearing grease or engine oil.

Adjustment of the oil pump

The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.

Bar 18"-20": Position 3

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.

Centrifugal cleaning “Turbo”

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

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 carburettor compartment.

CS 2141 EPA II, CS 2145 EPA II, CS 2150 EPA I specifications

The Jonsered CS 2150 EPA I, CS 2145 EPA II, and CS 2141 EPA II are premium chainsaws engineered for both professional users and serious enthusiasts. These models exemplify Jonsered's commitment to power, efficiency, and user-friendly design, making them ideal for a variety of cutting tasks, from felling trees to trimming branches.

The Jonsered CS 2150 EPA I is a robust chainsaw that offers a powerful engine combined with advanced features. It boasts a 50.2 cc engine that delivers exceptional cutting performance while adhering to strict EPA emissions standards. The chainsaw is equipped with the X-Torq engine technology, which significantly reduces fuel consumption and emissions, enabling users to work longer while minimizing environmental impact. Additionally, the CS 2150 features a high chain speed of 22.3 m/s, allowing for swift and clean cuts.

The CS 2145 EPA II further enhances performance with its lightweight design, making it easy to maneuver for prolonged use without fatigue. Powered by a 45.7 cc engine, it combines efficiency with raw power, providing reliable performance for both professionals and homeowners. The inclusion of an easy-start system means that users can start the saw with minimal effort, which is especially advantageous during colder weather or when working in challenging environments. Its validated safety features, including a chain brake and low kickback bar, ensure user protection during operation.

The CS 2141 EPA II offers a perfect balance of power and manageability. With a smaller 40.9 cc engine, it is particularly suited for users looking for an efficient saw that doesn't compromise on performance. The lightweight design allows for easy handling, particularly in dense and difficult terrain. Like the other models, it utilizes the X-Torq engine technology, which ensures reduced emissions and optimal fuel efficiency. Its precise design and ergonomic handle make it comfortable for extended periods of use, catering to both professional loggers and landscape maintenance users.

Each of these models shares characteristics such as an efficient air filtration system, which prolongs engine life by keeping dirt and debris out.
