A. Removing Debris from Engine
Before each use, remove all dirt and debris from the
following areas:
• Cooling Fins
• Air Inlets
• Fuel Fill Cap Air Vent
• Air Vent Screw
• Levers and Linkage
Removing debris will insure adequate cooling, correct
engine speed and reduce the risk of fire. See Figure 18.
Some engines are equipped with an optional foam debris
guard or a metal debris guard called the “Top Hat”. Both
debris guards must also be kept clean to prevent engine
overheating. See Figure 19.
NOTES
Contact your Authorized TecumsehPower Servicing Dealer
for genuine replacement Air Intake Debris Guard Kits.
Inspect foam debris guard for discoloration or dirt
accumulation. If either is present, see “I. Servicing Foam
Filters” and/or "II. Servicing Screens" on page 10.
