USA : ANSI Standard B175.1-2000 Safety Requirement for chain saws Canada : CSA Standard Z 62.1, Standard Z 62.3 CHAIN SAWS WARNING DANGER ANSI STANDARD B 175. 1-2000 STIPULATES THAT THE BRAKE SHALL STOP THE CHAIN 0.12 SECONDS AT AN ENGINE SPEED OF 13,500 r/min. IT IS THE RESPONSIBILITY OF THE OWNER / OPERATOR TO ENSURE THAT THE BRAKE IS SERVICED, ADJUSTED AND TESTED STRICTLY IN ACCORDANCE WITH THE INSTRUCTIONS AS DETAILED HEREIN IN ORDER TO ENSURE THAT THE BRAKE PERFORMANCE IS MAINTAINED IN COMPLIANCE WITH THE STANDARD B 175. 1-2000. 7 PREPARATION FOR USE Bar hole Clutch cover Adjusting screw CAUTION · All adjustment, should be made cold. · Always wear gloves when working on chain. Proper tension Improper tension MOUNTING GUIDE BAR AND CHAIN · Unscrew two nuts and remove clutch cover. · Install the spiked bumper on the front of machine. (Use two bolts 5.12) Two bolts 5.12 Spiked bumper • Mount bar and slide toward clutch to make saw chain installation easier. • Install saw chain as shown. (Ensure cutters are pointing in the right direction) • Install the clutch cover tighten nuts finger tight. Ensure that chain tension adjuster fits into bar hole. NOTE Ensure that the chain is installed with the cutters directed forward on the top of the bar. ADJUSTMENT, CHAIN TENSION • Hold the bar nose up and turn the adjuster clockwise until the chain fits snugly against the underside of the bar. • Tighten both nuts with the bar nose held up. • Start the engine and run at low speed. Stop and readjust if necessary. 8 FUEL AND LUBRICANT Oil Gasoline 50 1 50 : 1 (US) (METRIC) GAS OIL GAS OIL Gal Fl oz L mL 1 2.6 4 80 2 5.1 8 160 512.820400 OIL TANK CAP FUEL TANK CAP CAP INDICATION Fuel/oil tanks are indicated by the following illustrations FUEL STATEMENT GASOLINE-Use 89 Octane [ R+M] gasoline or 2 gasohol known to be good quality. Gasohol may contain maximum 10% ethyl (grain) alcohol or 15% MTBE (methylteriary-butyl ether). Gasohol containing methyl (wood) alcohol is not approved. TWO-STROKE OIL - Use 50 : 1 two-stroke ECHO oil only. Engine problems due to inadequate lubrication caused by failure to use 50 : 1 ECHO oil will void the warranty on your ECHO product. MIXING - Mix oil and gasoline/gasohol according to the instructions on the ECHO oil label. IMPORTANT Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30) days, ninety (90) days when a fuel stabilizer is added. Stored two-stroke fuel may separate. ALWAYS shake fuel container thoroughly before each use. CAUTION Whenever opening up the fuel tank, always loosen the cap very slowly and wait for the tank pressure to be equalized before removing the cap. CHAIN LUBRICANT Proper lubrication of the chain while in operation reduces friction between the chain and the guide bar to a minimum and assures a longer service life. • Use ECHO bar and chain oil of high quality for this purpose. • Do not use used or reclaimed oil to avoid various oiler problems. • When refueling, also refill chain oil. 9 OPERATION Chain brake Stop switch Start Choke Open WHEN THE ENGINE IS COLD • Fill the fuel tank with fuel. • Fill the chain oil tank with lubricant. • Press hand guard forward. (Chain brake ACTIVATED position) • Turn ignition switch upside. (“RUN” position) • Pull choke control knob all the way out. (Choke position) CAUTION Make sure bar and chain are free from any obstruction when starting the saw. • Make sure guide bar and saw chain are not touching anything when starting the saw. • Securely hold the saw as shown and pull starter handle several times until first firing sound. • Push choke control knob all the way in. • Pull starter handle to start the engine. • When engine starts, immediately pull throttle trigger up to release the latch, then release throttle trigger. CAUTION The chain will attempt to rotate when engine is started with throttle latch engaged. After engine starts, release throttle trigger to idle engine, otherwise brake damage may occur. Never use the latch for cutting. Use it only when starting the engine. WHEN THE ENGINE IS WARM • Confirm fuel and chain oil in the tanks. • Press hand guard forward. (Chain brake ACTIVATED position) • Turn ignition switch upside. (“RUN” position) • Make sure guide bar and saw chain are not touching anything when starting the saw. • Securely hold the saw as shown and pull starter handle. • Choke may be used if necessary but after first firing sound, pull throttle trigger a little to release throttle locking and choke. 10 Stop RUNNING • When engine starts, keep idling for a few minutes. • Pull throttle trigger gradually and increase revolution of the engine. • The chain starts running when the engine reaches to 3,800 r/min approximately. • Confirm proper acceleration and lubrication of chain and bar. STOPPING • Release throttle trigger and turn switch down. (“STOP” position) NOTE When engine does not stop, pull choke control knob out fully to stop engine. Check and repair stop switch before starting the engine ag...
