User manual MAKITA DCS3500

[. . . ] Instruction Manual DCS3500 DCS3501 DCS4300 DCS4301 Important: Read this instruction manual carefully before putting the chain saw into operation and strictly observe the safety regulations!Keep this instruction manual! Thank you for purchasing a MAKITA product! Congratulations on choosing a MAKITA chain saw!We are conÞdent that you will be satisÞed with this modern piece of equipment. The DCS3500-DCS4301 are very handy and robust chain saws with a new Design. [. . . ] Check the chain tension frequently - new chains tend to get longer during use!In order to guarantee uniform wear of the guide bar the bar should be turned over whenever replacing the chain. 2 Retensioning the saw chain All that is necessary to retension the saw chain is to loosen the quick tensioner (2) slightly as described under "Mounting the guide bar and saw chain". Tension the chain as already described. Chain brake The DCS3500-DCS4301 comes with an inertia chain brake as standard equipment. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS, page 6), the chain brake will stop the chain through inertia if the kickback is sufÞciently strong. The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergency. IMPORTANT: NEVER run the saw with the chain brake activated (except for testing, see "Testing chain brake")!ALWAYS release the chain brake before starting the work! 2 1 Engaging the chain brake (braking) If the kickback is strong enough the sudden acceleration of the guide bar combined with the inertia of the hand guard (1) will automatically actuate the chain brake. 1 To engage the chain brake manually, simply push the hand guard (1) forward (towards the tip of the saw) with your left hand (arrow 1). Releasing the chain brake Pull the hand guard (1) towards you (arrow 2) until you feel it catch. The brake is now released. 18 Fuel CAUTION: This saw is powered by mineral-oil products (gasoline and oil). Do not smoke (explosion hazard). Gasoline 40:1 50:1 100:1 Fuel mixture The engine of the chain saw is a high-efÞciency two-stroke engine. In case no such fuel is available, you can use fuel with a higher octane value. In order to obtain an optimum engine output and to protect your health and the environment use unleaded fuel only. For lubricating the engine use a two-stroke engine oil (quality grade: JASO FC or ISO EGD), which is added to the fuel. The engine has been designed for use of MAKITA HP 100 highperformance two-stroke engine oil and a mixture ratio of only 100:1 to protect the environment. In addition, a long service life and reliable operation with a minimum emission of exhaust gases are ensured. MAKITA HP 100 high performance two-stroke oil is available in two sizes: 0, 5 l order number 980 008 609 MAKITA high-performance two-stroke engine oil is available in the following sizes to suit your individual requirements: 1l 100 ml order number 980 008 607 order number 980 008 606 + 1000 cm3 5000 cm3 (1 litre) (5 litres) OIL 25 cm3 125 cm3 250 cm3 20 cm3 100 cm3 200 cm3 10 cm3 50 cm3 100 cm3 10000 cm3 (10 litres) It is not wise to add more engine oil than speciÞed to ensure safe operation. This will only result in a higher production of combus-tion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the mufßer. In addition, fuel consumption will rise and performance will decrease. The Storage of Fuel Fuels have a limited storage life. Fuel and fuel mixtures age through evaporation, especially at high temperatures. Aged fuel and fuel mixtures can cause starting problems and damage the engine. Purchase only that amount of fuel, which will be consumed over the next few months. At high temperatures, once fuel has been mixed it should be used up in 6-8 weeks. Store fuel only in proper containers, in dry, cool, secure locations! In case MAKITA high-performance two-stroke engine oil is not available, it is urgently recommended to use a mixture ratio of 40:1 with other two-stroke engine oils, as otherwise optimum operation of the engine cannot be guaranteed. [. . . ] Use of unsuitable spare parts or parts which are not original MAKITA parts, insofar as they have caused the damage. Damages caused by disregarding loose outer bolted connections. Cleaning, servicing and adjustment work is not covered by the guarantee. All repairs covered by the guarantee must be performed by a MAKITA service centre. 34 Trouble shooting Malfunction Chain does not run Engine does not start or only with difÞculty System Chain brake Ignition system Observation Engine runs Ignition spark No ignition spark Fuel supply Fuel tank is Þlled Cause Chain brake actuated.
