Resumen del manual
The only time the lubricant needs attention is if service has been performed on the gear case. • If lubricant is required, use only Ronex ED #1 grease. TRACTION DRIVE SYSTEM DO NOT lubricate the drive components inside the snow thrower. The sprockets, hex shafts, drive disc and friction wheel require no lubrication. The bearings and bushings are lifetime lubricated and require no maintenance. CAUTION: Any lubricating of the above com po nents can cause contamination of the friction wheel and damage to the drive system of your snow thrower. ENGINE See engine manual. LUBRICATION Use only high quality detergent oil rated with API service classification SF-SJ. Select the oil's SAE viscosity grade according to your expected operating temperature. NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil. Change the oil after every 50 hours of operation or at least once a year if the snow thrower is not used for 50 hours in one year. Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil fill cap / dipstick securely each time you check the oil level. TO CHANGE ENGINE OIL Determine temperature range anticipated before next oil change. All oil must meet API service classification SF-SJ. • Be sure snow thrower is on level surface. • Oil will drain more freely when warm. • Catch oil in a suitable container. NOTE: The left side wheel may be removed from snow thrower for easier access to the oil drain plug and placement of a suitable container. The unit tilted, resting on the frame with the left wheel removed, will help drain any oil trapped inside the engine. (See “TO REMOVE WHEELS” in the Service and Adjustments section of this manual). 1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug. 2. Clean area around drain plug. 3. Remove drain plug and drain oil in a suitable container. 4. Install drain plug and tighten securely. 5. Wipe off any spilled oil from snow thrower and engine. 6. Install left wheel (if removed for draining oil). Be sure to install klick pin into proper hole in wheel axle (See “TO REMOVE WHEELS” in the Service and Adjustments section of this manual). 7. Remove oil fi ll cap/dipstick. Be careful not to allow dirt to enter the engine. 8. Refill engine with oil through oil dipstick tube. Pour slowly. Do not overfill. For approximate capacity see “PRODUCT SPECIFICATIONS” section of this manu al. 9. Use gauge on oil fill cap/dipstick for checking level. Be sure dipstick cap is tightened securely for accurate reading. Keep oil at “FULL” line on dipstick. 10. Wipe off any spilled oil. MUFFLER Inspect and replace corroded muffler as it could cre ate a fi re haz ard and/or dam age. SPARK PLUG Replace spark plug at the beginning of each season or after every 100 hours of operation, whichever occurs first. Spark plug type and gap setting are shown in the “PROD UCT SPEC I FI CATIONS” section of this manual. CLEANING IMPORTANT: For best performance, keep snow thrower housing free of any dirt or trash. Clean the outside of your snow thrower after each use. WARNING: Disconnect spark plug wire from spark plug and place wire where it can not come in contact with spark plug. • Keep finished surfaces/wheels free of gasoline, oil, etc. • We do not recommend using a garden hose to clean your snow thrower unless the electrical system, muffler and carburetor are covered to keep water out. Water in engine can result in shortened engine life. 15 16 SERVICE AND ADJUSTMENTS WARNING: To avoid serious injury, before performing any service or adjust ments: 1. Be sure throttle is in STOP position. 2. Remove safety ignition key. 3. Make sure the augers and all mov ing parts have completely stopped. 4. Disconnect spark plug wire from spark plug and place wire where it can not come in contact with plug. SNOW THROWER TO ADJUST SNOW THROWER HEIGHT See “TO ADJUST SKID PLATES” and “SCRAPER BAR” in the Operation section of this manual. CHUTE DEFLECTOR The chute defl ector, attached to the top of the discharge chute, is provided to direct discharging snow away from the operator. If the defl ector becomes damaged, it should be re placed. WARNING: To avoid serious injury, nev er operate your snow thrower with the defl ector removed or damaged. • To change direction and/or distance snow is dis charged, see “TO CONTROL SNOW DISCHARGE” in the Oper a tion section of this manual. SHEAR BOLTS (See Fig. 18) AUGER SHEAR BOLTS Both right and left-hand augers are secured to the auger shaft with a shoulder/shear bolt and hex nut. Should a foreign object or ice become lodged in the augers, the shear bolts are designed to break, preventing damage to any other com po nents. If one or both augers do not turn when auger ...
