A contaminated fuel filter should be replaced with a new Shindaiwa replacement element. Before reinstalling the filter, inspect the condition of the fuel line. If you note damage or deterioration, the blower should be removed from service until it can be inspected by a Shindaiwa- trained service technician. COOLING SYSTEM Use a wood or ¦¦ plastic scraper and a soft brush to remove dirt and debris from the cylinder fins and crankcase. Hooked Wire Fuel Filter SPARK PLUG Replace the spark plug ¦¦ with a NGK CMR5H (or equivalent), gapped to 0.6 mm (0.024”). Fuel Tank Figure 23 CAUTION! Make sure you do not pierce the fuel line with the end of the hooked wire. The line is delicate and can be damaged easily. 139/150-Hour Maintenance NOTE: The NGK CMR5H also meets the require- ments for electro magnetic compliance (EMC). Maintenance after first 139-hours, then every 150-hours thereafter. Replace the spark plug annually: Use ¦¦ onlyNGK CMR5H or equivalent resistor type spark plug of the correct heat range. Set spark plug electrode gap to 0.6 mm (0.024 inch). Combustion chamber should be decar¦ ¦ bonized, and the valve clearance should be adjusted. It is highly recommended that this is done by a Shindaiwa-trained service technician. 16 Troubleshooting Guide ENGINE DOES NOT START Possible Cause What To Check Remedy Faulty recoil starter. Does the engine crank? NO Consult with an authorized servicing dealer. Fluid in the crankcase. YES Internal damage. Good compression? NO Tighten and re-test. Loose spark plug. YES Consult with an authorized servicing dealer. Excess wear on cylinder, piston, rings. Does the tank contain fresh fuel of the proper grade? NO Fuel incorrect, stale, or contaminated; mixture incorrect. Refill with fresh, clean unleaded gasoline with a pump octane of 87 or higher mixed with 50:1 Shindaiwa Premium 2-cycle mixing oil or with an equivalent high quality 2-cycle mixing oil. YES Check for clogged fuel filter and/or vent. Replace fuel filter or vent as required. Restart. NO Is fuel visible and moving in the return line when priming? Priming pump not functioning properly.. Consult with an authorized servicing dealer. YES Move switch to “I” (ON) position and restart. The ignition switch is in “O” (OFF) position. NO Is there spark at the spark plug wire terminal?

Crank the engine with the plug removed, reinstall the plug, and restart. Check the spark plug. Clean and regap the plug to 0.6mm. Restart. The plug is fouled or improperly gapped. The plug is damaged internally or of the wrong size. Replace the spark plug. Check the unit Specifications page for the proper spark plug for your unit. Restart. 17 Troubleshooting Guide LOW POWER OUTPUT What To Check Possible Cause Remedy Operator is overworking the unit. Operate at slower rate. Is the engine overheating? Carburetor mixture is too lean. Consult with an authorized servicing dealer. Improper fuel ratio. Refill with clean fresh unleaded gasoline with a pump octane of 87 or higher, mixed with Premium 2-cycle mixing oil at a 50:1 gasoline/oil ratio. Clean intake cover.. Fallen leaves or debris on intake cover.. Clean, repair or replace as necessary. Fan, fan cover, cylinder fins dirty or damaged Carbon deposits on the piston or in the muffler. Consult with an authorized servicing dealer Clogged air cleaner element. Clean or replace the air filter Engine is rough at all speeds. May also have black smoke and/or unburned fuel at the exhaust. Loose or damaged spark plug. Tighten or replace the spark plug. Restart. Check the Product Specifications page in this manual for the correct spark plug for this unit. Repair or replace fuel filter and/or fuel line. Air leakage or clogged fuel line. Water in the fuel. Refill with fresh fuel/oil mixture. Piston seizure. Consult with an authorized servicing dealer. Faulty carburetor and/or diaphragm Overheating condition. Consult with an authorized servicing dealer. Engine is knocking. Improper fuel. Check fuel octane rating; check for presence of alcohol in the fuel. Refuel as necessary. Carbon deposits in the combustion chamber. Consult with an authorized servicing dealer. Engine speed is reduced. Heat sensor is activated, due to restricted air flow at intake cover. Stop the engine. Clean debris blocking intake cover. Restart. Idle more than 1 minute. If engine speed is reduced again, consult with an authorized servicing dealer. Troubleshooting Guide ADDITIONAL PROBLEMS Remedy Possible Cause What To Check Clean or replace the air filter. Clogged air filter. Poor acceleration. Clogged fuel filter. Replace the fuel filter. Consult with an authorized servicing dealer. Lean fuel/air mixture. Adjust: 2,000 (±200) min-1. Idle speed set too low. Reset the switch and re-start. Ignition switch turned off. Refuel. See Fuel section of manual. Fuel tank empty. Engine stops abruptly....
