STARTING AND STOPPING

Starting and stopping

WARNING! Note the following before

!starting:

Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the clutch can come loose and cause personal injuries.

Always move the machine away from the refuelling area before starting.

Place the machine on firm ground. Make sure you have a secure footing and that the chain cannot touch anything.

Keep people and animals well away from the working area.

Cold engine

Starting: The chain brake should be activated when starting the chain saw. Activate the chain brake by pushing the front hand guard forwards.

Ignition; choke: Set the choke control in the choke position. This should automatically set the stop switch to the start position.

H

Start throttle: The correct choke/start throttle setting is obtained by moving the control to the choke position.

If the machine is fitted with a decompression valve (A): Press the valve to reduce the pressure in the cylinder and make starting easier. You should always use the decompression valve when starting the machine. Once the machine has started the valve will automatically return to its original setting.

A

Warm engine

Use the same procedure as for starting a cold engine but without setting the choke control in the choke position. The correct choke/start throttle setting is obtained by moving the choke control to the choke position and then pushing it in again.

H

Starting

Grip the front handle with your left hand. Hold the chain saw on the ground by placing your right foot through the rear handle. Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull firmly and rapidly. Never wrap the starter cord around your hand

As the chain brake is still activated the engine must return to idling speed as soon as possible by disengaging the throttel latch in order to avoid unnecessery wear on the clutch assembly.

Push in the choke control as soon as the engine fire and make repeated starting attempts. Immediately press and release the throttle when the engine starts. That will disengage the throttle latch.

CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.

Pull the front hand guard towards the front handle. The chain brake is now disengaged. Your saw is ready for use.

Stopping

Stop the engine by switching off the ignition.

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. In addition, they are designed with vibrations dampening technology, reducing fatigue for the user.
