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.

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.

•Preheat the intake air to the carburetor by using the heat from the cylinder.

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.

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 2152 EPA III, CS 2153 EPA I specifications

Jonsered, a renowned name in the outdoor power tool industry, has produced a range of high-performance chainsaws designed for both professional and hobbyist use. Two noteworthy models are the Jonsered CS 2153 EPA I and the CS 2152 EPA III. Both chainsaws boast a combination of power, efficiency, and innovative technology, making them ideal for various cutting tasks.

The Jonsered CS 2153 EPA I is equipped with a robust 50cc engine that delivers an impressive power output, allowing for quick and efficient cutting through a variety of wood types. The chainsaw features a lightweight design, ensuring ease of handling and reduced fatigue during prolonged use. One of the standout features of the CS 2153 is its Rapid Reaction Start system, which significantly decreases starting effort and ensures a reliable ignition. This makes it particularly convenient for users who need to start the chainsaw multiple times throughout the day.

Additionally, the CS 2153 incorporates an ergonomic handle design, which improves comfort and control. The anti-vibration technology integrated into the saw helps to minimize the amount of vibration transferred to the user's hands, contributing to a smoother operation and less strain during long cutting sessions. Furthermore, the chainsaw comes with a tool-less chain tensioning system, allowing for quick adjustments without the need for additional tools, enhancing efficiency and saving valuable time.

On the other hand, the Jonsered CS 2152 EPA III features a slightly smaller yet powerful 40cc engine, making it an ideal choice for both light-duty and medium-duty cutting applications. Similar to the CS 2153, this model also boasts a lightweight and well-balanced design, making maneuverability easy for users. The CS 2152 is known for its exceptional fuel efficiency, thanks to the innovative X-Torq engine technology, which reduces fuel consumption and minimizes harmful emissions. This feature not only makes it environmentally friendly, but also reduces running costs over time.

Both models highlight Jonsered's commitment to user safety with a chain brake system that stops the chain in the event of kickback and a handguard to protect the user's hands. Overall, the Jonsered CS 2153 EPA I and CS 2152 EPA III are exceptional chainsaws, combining power, efficiency, and comfort in a user-friendly package. Whether you're a professional logger or a homeowner tackling occasional yard work, these chainsaws are sure to meet your cutting needs effectively and reliably.
