COOLING SYSTEM CLEANING
Before each use check to make sure the air intake screen is
free from grass and debris and clean if necessary.
Every 100 hours of operation, check and clean the cooling
fins and inside the engine shrouds to remove grass, chaff or
dirt clogging the cooling system and causing overheating.
CAUTION: Do not run the engine before all
cooling system parts are reinstalled to keep the
cooling and carburetion as intended.
2. Clean the electrodes by scraping with a wire brush to
remove carbon deposits.
