Ryobi RY40402A Operation Manual - Page 12

OPERATION FILLING THE TANK  Clean the surface around the fuel cap to prevent contamination.  Loosen the fuel cap slowly by turning counterclockwise.  Pour the fuel carefully into the tank.  Clean and inspect the fuel cap gasket before replacing the fuel cap.  Replace the fuel cap and tighten it by turning it clockwise.  Wipe spilled fuel from the product.  Move at least 30 ft. away from refueling area before starting the product. NOTE: It is normal for smoke to be emitted from a new engine during first use. To add engine lubricant:  Remove the cap and seal from lubricant bottle provided.  Unscrew the oil cap/dipstick and remove.  Using funnel provided, add entire bottle of engine lubricant through oil fill hole.  Reinstall the oil cap/dipstick and secure. To check engine lubricant level:  Set unit on a flat surface.  Wipe dipstick clean and re-seat in hole; do not rethread.  Remove dipstick again and check lubricant level. Lubricant level should fall within the hatched area on the dipstick.  If level is low, add engine lubricant until the fluid level rises to the upper portion of the hatched area on the dipstick.  Replace and secure the oil cap/dipstick. WARNING: Always shut off engine before fueling. Never add fuel to a machine with a running or hot engine. Move at least 30 ft. from refueling site before starting engine. Do not smoke and stay away from open flames and sparks. Failure to safely handle fuel could result in serious personal injury. CAUTION: Do not overfill. Overfilling the crankcase may cause excessive smoke, oil loss, and engine damage. ­ STARTING AND STOPPING OXYGENATED FUELS DO NOT USE E85 FUEL. IT WILL VOID YOUR WARRANTY. NOTE: Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates stated below are not covered under warranty. Ethanol. Gasoline containing up to 10% ethanol by volume (commonly referred to as E10) is acceptable. E85 is not. CAUTION: Attempting to start the engine before it has been properly filled with lubricant will result in equipment failure. ADDING/CHECKING ENGINE LUBRICANT See Figure 4. Engine lubricant has a major influence on engine performance and service life. This unit is shipped with a 20W50 engine lubricant to assist in the break-in period. For best operating performance, continuing to use 20W50 engine lubricant is recommended, however, SAE 30, 10W30, or 10W40 are all acceptable lubricants to use in this product. Always use a 4-stroke motor lubricant that meets or exceeds the requirements for API service classification SJ. Check lubricant level before each use. NOTE: Non-detergent or 4-cycle engine lubricants will damage the engine and should not be used. See Figures 5 - 6. Blower should be on a flat, bare surface for starting.  Slowly press the primer bulb 10 times. NOTE: After the 7th press, fuel should be visible in the primer bulb. If it is not, continue to press the primer until you see fuel in the bulb.  Set the choke lever to the FULL CHOKE position.  Do not squeeze the throttle trigger. Start the unit with the throttle/cruise control lever in the IDLE position. Pull the starter grip sharply until engine attempts to run (no more than 4 pulls).  Set the choke lever to the HALF CHOKE position.  Pull the starter grip until the engine runs. Do not pull the starter grip more than six (6) times. NOTE: If the engine does not start, return to the FULL CHOKE position and repeat the steps that follow.  Allow the engine to run for 15 seconds, then set the choke lever to the RUN position. TO STOP THE ENGINE:  To stop the engine, depress the STOP switch to the stop position " ". HOT RESTART OF THE ENGINE:  Set the choke lever to the RUN position.  Set the throttle/cruise control lever to IDLE.  Do not squeeze the throttle to start a hot engine.  Pull the starter grip until the engine runs. 8 - English
