Frequently Asked Questions
How often should Westwood air filters be replaced?
Replace paper air filters every 25 hours of operation or annually, whichever comes first, though dusty conditions require more frequent changes (every 10-15 hours). Foam filters can be washed and reused but need annual replacement.
Can I clean a Westwood paper air filter?
Paper air filters cannot be effectively cleaned as water damages the element and compressed air doesn't remove embedded particles. Always replace paper filters; cleaning attempts reduce filtration efficiency risking engine damage.
What happens if I run my Westwood without an air filter?
Operating without air filters allows dirt to enter cylinders causing rapid piston ring and cylinder wall wear, reduced compression, increased oil consumption, and ultimately catastrophic engine failure. Never operate without proper filtration.
How do I clean foam air filters properly?
Wash foam filters in warm soapy water, rinse thoroughly, squeeze gently (don't wring), allow complete air drying, then apply light coat of foam filter oil before reinstallation. Never use petroleum-based cleaners.
Why does oil appear on my Westwood air filter?
Oil on air filters indicates overfilled crankcase allowing oil past breather system, clogged breather tubes creating excessive crankcase pressure, or tipping mower incorrectly during maintenance. Check oil level and breather function.
