Use and Care Manual
2.  Replace paper element when dirty or damaged. Clean 
foam element or replace when damaged. 
3.  To clean foam element, separate it from the paper element 
and wash in liquid detergent and water. Allow to dry 
thoroughly before using. Do not oil the foam element.
Adjustments
DO NOT make any engine adjustments. Factory settings are 
satisfactory for most conditions. If adjustments are needed, 
contact your Authorized MTD Servicing Dealer.
Carburetor
If you think you carburetor needs adjusting, see your nearest 
Authorized MTD Servicing Dealer. Engine performance should 
NOT be affected at altitudes up to 7,000 feet (2,134 meters). For 
operation at higher elevations, contact your Authorized MTD 
Servicing Dealer
Alternator (if equipped)
Contact your Authorized MTD Servicing Dealer for alternator 
related electrical problems such as:
•  Inoperative Starter
•  Discharged Battery
•  Fuse Replacement
•  Alternator Maintenance/Repairs
Engine Speed
WARNING! To avoid serious injury or death, DO 
NOT modify engine in any way. Tampering with the 
governor setting can lead to a runaway engine and 
cause it to operate at unsafe speeds. NEVER tamper 
with the factory setting of the engine governor. 
WARNING! Running the engine faster than the 
speed set at the factory can be dangerous and will 
VOID THE ENGINE WARRANTY.
Removing Snow from the Engine
After each use, remove snow from the following areas:
•  Oil Fill Cap Dipstick
•  Fuel Fill Cap
•  Recoil Starter/Flywheel Screen
•  Linkage
•  Guards
•  Spark Plug Connection (if visible).
•  Electric Starter Switch Box, if present (see the 
equipment Operator’s Manual instructions). 
NOTE: See the equipment Operator’s Manual instructions 
for proper location of fuel fill cap and control lever.
1.  Removing snow will ease operation of the recoil starter 
rope and reduce the risk of water contamination when 
opening the fuel fill cap.
NOTE: For more information about recoil starters, see 
Engine’s with Recoil Starters in the Operation Section of 
this manual.
Transporting Your Engine
WARNING! NEVER transport this engine inside of 
another vehicle or in any enclosed space if there is 
any gasoline in the tank. Fuel vapor or spilled fuel 
may ignite.
WARNING ! If there is fuel in the fuel tank, close 
the fuel valve, if equipped, and transport the engine 
upright in an open vehicle, such as an open trailer or 
open bed of a pickup truck.
If you DO NOT have an open vehicle and have to transport 
the engine upright in a closed vehicle, follow these steps for 
emptying the fuel tank before transporting:
1.  Empty fuel tank by using a commercially available suction 
device designed for use with gasoline.
WARNING! DO NOT pour fuel from the engine or 
siphon fuel by mouth.
2.  Drain fuel into an approved red gasoline container, being 
careful to avoid spilling.
3.  Run the engine until remaining fuel is consumed. 
WARNING! NEVER leave the engine unattended 
when it is running and NEVER run the engine in an 
enclosed area.
Storing Your Engine 
Short-Term/Seasonal Storage
Clean Engine
If the engine has been running, allow it to cool for at least half an 
hour before cleaning. 
Before servicing the engine, remove the carburetor cover and/or 
blower housing. Discard the dirt and debris from the following 
areas:
•  Cooling Fins
•  Air Intake Screen or Recoil Starter/Flywheel 
Guard Areas
•  Spark Plug Connection
•  Levers
•  Linkage Area
•  Guards
•  Carburetor
•  Head
Removing debris will insure adequate cooling, correct engine 
speed and reduce the risk of fire.
NOTE: Do not spray engine with water to clean because water 
could contaminate fuel. Using a garden hose or pressure washing 
equipment can also force water into the air cleaner or muffler 
opening. Water in the air cleaner will soak the paper element, 
and water that passes through the element or muffler can enter 
the cylinder, causing damage.
