Clean Debris from Engine & Chipper
Check for dirt and debris before each use and every 100 hours.
The engine requires air flow to cool itself and for combustion.
Before each use, clean any debris from the unit especially from
around the air shroud intake, air filter, and muffler. Every 100
hours, remove the engine air shroud and clean out any debris
from the engine cooling fins. We recommend having this service
performed by an authorized dealer.

NOTE: Operating engine with loose or damaged air cleaner
components could cause premature wear and failure. Replace all
bent or damaged components.
1. Unhook cover latch and remove air cleaner cover.
2. Remove and replace paper element.
3. Remove foam element; replace or wash in warm water with
detergent. Rinse and allow to air dry, then replace.
4. Reinstall air cleaner cover and secure cover latch.
