To reduce the risk of serious injury or death from fires and/or explosions, NEVER use flammable
solvents (e.g., gasoline) to clean serviceable parts. Use a water-based, non-flammable solvent
such as Tecumseh Degreaser Cleaner.
NEVER use compressed air to clean debris from yourself or your clothing. When using compressed
air to clean or dry serviceable parts:
• Wear appropriate eye protection.
• Use only approved air blow nozzles.
• Air pressure must not exceed 30psi (206kPa).
• Shield yourself and bystanders from flying debris.
CAUTION
Should more extensive repair be needed, we recommend you contact a local Tecumseh Servicing Dealer for repair.
Repair
manuals are also available from your local dealer or direct from Tecumseh. A complete list of the available
manuals can be found at the end of this book.
NOTE: Refer to Technician's Handbook for a more detailed list of remedies.
