GT-225 MAINTENANCE or HERE https://www.shindaiwa-usa.com/you-can.aspx For information about maintenance kits.
MAINTENANCE GT-225 * Replacement is recommended based on the finding of damage or wear during inspection. Air Filter Level 1. Parts Required: Tune-Up Kit 1. Close choke (COLD START [ ] position). This prevents dirt from entering the carburetor throat when the air filter is removed. Brush accumulated dirt from air cleaner area. 2. Remove air filter cover. Brush dirt from inside cover. 3. Replace filter if it is damaged, fuel soaked, very dirty, or the rubber sealing edges are deformed.
GT-225 MAINTENANCE Fuel Filter Level 1. Parts Required: TUNE UP KIT. Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal injury may result. 1. Use a clean rag to remove loose dirt from around fuel cap and empty fuel tank. Do not damage fuel line while removing fuel filter from tank or line. 2. Pull the fuel filter from the tank. 3. Do not remove the wire coil clamp to remove the fuel filter.
MAINTENANCE GT-225 Spark Plug Level 2. Parts Required: Tune-Up Kit Use only NGK BPM8Y spark plug (BPMR8Y in Canada) otherwise severe engine damage may occur. 1. Remove spark plug and check for fouling, worn and rounded center electrode. 2. Clean the plug or replace with a new one. DO NOT sand blast to clean. Remaining sand will damage engine. 3. Adjust spark plug gap by bending outer electrode. 4. Tighten spark plug to 150-170 kgf•cm (130-150 in•lbf). 28 0.65 mm (0.026 in.
GT-225 MAINTENANCE Cooling System Level 2. To maintain proper engine operating temperatures, cooling air must pass freely through the cylinder fin area. This flow of air carries combustion heat away from the engine. Overheating and engine seizure can occur when: • Air intakes are blocked, preventing cooling air from reaching the cylinder. • Dust and grass build up on the outside of the cylinder. This build up insulates the engine and prevents the heat from leaving.
MAINTENANCE 4. Use a brush to remove dirt from the cylinder fins. 5. Remove ignition wires from clip for cleaning. 6. Remove grass and leaves from the grid between the recoil starter and fuel tank. 7. Assemble components in reverse order. GT-225 Exhaust System Spark Arrestor Screen Level 2. Parts Required: Spark Arrestor Screen, Gasket 1. Remove spark plug lead and engine cover. 2. Place piston at Top Dead Center (TDC) to prevent carbon/dirt from entering cylinder.
GT-225 3. 4. MAINTENANCE Remove spark arrestor screen cover (C), gaskets (D), (E), and screen (F), from muffler body. F Clean carbon deposits from muffler components. E Note: When cleaning carbon deposit, be careful not to damage the catalytic element inside muffler. 5. Replace screen if it is cracked, plugged, or has holes burned through. 6. Assemble components in reverse order. D C Exhaust Port Cleaning Level 2. Parts Required: As needed: Heat Shield 1.
MAINTENANCE GT-225 Never use a metal tool to scrape carbon from the exhaust port. Do not scratch the cylinder or piston when cleaning the exhaust port. Do not allow carbon particles to enter the cylinder. 4. Inspect heat shield, and replace if damaged. 5. Install heat shield and muffler. 6. Tighten muffler mounting bolts (or nuts) to 90-110 kgf•cm (80-95 in•lbf). 7. Install engine cover and attach spark plug lead. 8. Start engine, and warm to operating temperature. 9.
GT-225 1. MAINTENANCE Check idle speed and reset if necessary. If a tachometer is available, idle speed screw (A) should be set to the specifications found on “Specifications” page of this manual. Turn idle screw (A) clockwise to increase idle speed; counterclockwise to decrease idle speed. A A When carburetor adjustment is completed, the cutting attachment should not move at idle, otherwise serious personal injury may result. Lubrication Level 1. Parts Required: Lithium Based Grease. 1.
