WARNING
WARNING
Your Blower has been equipped with two air filters inside the housing. Accumulated debris and dust in the air filter will
reduce engine performance, increase fuel consumption and increases the risk of engine damage. Clean the air filters
every 5 hours of operation. It may be necessary to clean the air filter more often in dry conditions due to a large amount
of airborne debris.
Inspect the spark plug after every 10-15 hours of use; adjust spark plug gap and replace spark plug as necessary.
Replace spark plug every year to maintain engine performance and easy starting.
To inspect or replace the spark plug:
1. Remove the insulated spark plug boot.
2. Use the spark plug wrench to remove the spark plug,
by turning counter-clockwise.
3. Clean and adjust the spark plug gap to
0.024 – 0.028 inches (0.6 - 0.7 mm).
