CS45 / CS50 / CS56 Chainsaw Before starting the engine • Carefully check the area to make sure that no obstacles exist within a perimeter of 5 metres around the chain saw before starting the engine. • When starting the engine, place the body of the chain saw onto the ground in a flat clear area and hold it firmly in place to ensure that neither the blades nor the throttle come into contact with any obstacles when the engine starts up.
CS45 / CS50 / CS56 Chainsaw It is important to only use good quality, fresh petrol and oil. The two-stroke fuel mixture should be used within four weeks. IMPORTANT Stored two-stroke fuel may separate during storage, always shake fuel container before each use. DO NOT USE: • Fuel containing no oil (raw petrol) will cause the engine to become overheated and severe damage will occur which is not covered by warranty Fuelling WARNING 1. 2. 3. 4.
CS45 / CS50 / CS56 Chainsaw Chain Brake This machine is equipped with an automatic brake to stop the saw chain rotation upon the occurrence of kickback during saw cutting. The brake is automatically operated by inertial force, which acts on the weight fitted inside the front guard. The brake can also be operated manually by pushing the front guard forward towards the guide bar. To release the brake, pull back the front guard (4) toward the front handle (1) until a “click” sound is heard (2).
CS45 / CS50 / CS56 Chainsaw Kickback Safety Precautions Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Top contact in some cases may cause a lightning fast reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.
CS45 / CS50 / CS56 Chainsaw Operating the Engine 1. Fill fuel (2) and chain oil (1) tanks respectively, and tighten the caps securely. 2. Set the switch (3) to “I” position. 3. Press the primer button (4) 6 times. 4. Pull out the choke knob (5). The choke will close and the throttle will be set in the starting position. 5. Push in the decompressor valve (6). 6. Apply the chain brake by pushing the front hand guard (7) forwards. 7.
CS45 / CS50 / CS56 Chainsaw Hot engine 6 1. Set the switch (3) to “I” position. 2. Pull out the choke knob (5), then push the choke knob back in, this will set the throttle to the hot start position. 3. Push in the decompressor valve (6). 4. Apply the chain brake by pushing the front hand guard (7) forwards. 5. Pull the starter handle until the engine runs. 6. As soon as the engine is running, pull the throttle lever slightly to reset the throttle control to idle.
CS45 / CS50 / CS56 Chainsaw Checking the Oil Supply After starting the engine, run the chain at medium speed and see if chain oil is sprayed as shown in the figure.
