It is recommended to use Yamalube 4 10W-40 or a similar 4-stroke engine oil with an API service grade of SG or higher.
The air filter should be inspected and cleaned every 20 hours of operation or every month, whichever comes first. Replace it if it shows signs of wear or damage.
The recommended tire pressure for the front tires is 4.4 psi (30 kPa) and for the rear tires is 3.6 psi (25 kPa).
Check the battery connections, ensure the fuel is fresh, inspect the spark plug, and verify that the engine stop switch is in the "RUN" position.
Regular maintenance includes oil changes every 6 months or 100 hours, checking and cleaning the air filter, inspecting brake pads, and lubricating all pivot points.
The idle speed can be adjusted by turning the idle screw on the carburetor. The recommended idle speed is 1450–1550 rpm.
Stop the engine immediately, allow it to cool, check the coolant level, and ensure the radiator is not clogged with dirt or debris.
Maintain proper tire pressure, use the recommended oil, clean the air filter regularly, and avoid carrying excessive loads.
To replace the spark plug, remove the spark plug cap, use a spark plug wrench to remove the old plug, and install a new plug with the specified gap of 0.6-0.7 mm.
Locate the brake fluid reservoir, check the fluid level against the marked indicators, and ensure the fluid is at the recommended level. Top up with DOT 4 brake fluid if necessary.
