Maintenance Procedures

Regular maintenance ensures optimal performance and longevity.

1. Daily: Clean air filter (tap out debris or wash with soapy water if foam type).
2. Weekly: Check spark plug condition and gap (0.5 mm), clean cooling fins.
3. Monthly: Inspect fuel lines for cracks, check all fasteners for tightness.
4. Seasonally: Replace spark plug, clean carburetor (or have serviced by dealer).
5. Exhaust System: Regularly clean spark arrestor screen (if equipped).

CAUTION! Disconnect spark plug wire before performing any maintenance. Allow engine to cool completely.

Storage Guidelines

Proper storage prevents fuel system issues and corrosion.

1. Short-term (under 30 days): Add fuel stabilizer to fuel tank, run engine for 2 minutes to circulate treated fuel through system.
2. Long-term (over 30 days): Drain fuel tank completely, run engine until it stops from fuel starvation. Remove spark plug, add 1 teaspoon of engine oil through spark plug hole, pull starter cord slowly 2-3 times to coat cylinder, reinstall plug.
3. Store in clean, dry place, protected from dust and moisture. Cover with breathable cloth.

Tip: Store blower upright to prevent oil leakage.
