To prevent serious injury, never perform maintenance or repairs with unit
running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure
that the unit cannot start. See Replacing the Spark Plug.
MAINTENANCE SCHEDULE
Perform these required maintenance procedures at the frequency stated in the table. These procedures
should also be a part of any seasonal tune-up.
NOTE: Some maintenance procedures may require special tools or skills. If you are unsure about these
procedures take your unit to a Cub Cadet or other qualified service dealer.

FREQUENCY
Before using Fill fuel tank with fresh fuel*
Every 10 hrs Clean and re-oil air filter
Every 25 hrs Check spark plug condition and gap
Check the spark arrestor screen
* DO NOT use E85 fuel in this unit. It has been proven that fuel containing greater than 15% ethanol
will likely damage this engine and void the warranty.
AIR FILTER MAINTENANCE
Cleaning the Air Filter
Clean and re-oil the air filter every 25 hours of operation. It is an important item to maintain. Failure to maintain
your air filter properly can result in poor performance or can cause permanent damage to your engine.
1. Open the air filter cover. Push the locking tab on the top of the cover inward, then pull the air filter
cover out and down. (Fig. 16).
2. Remove the air filter (Fig. 17).

5. Squeeze the filter to spread and remove excess oil (Fig. 20).
6. Replace the filter (Fig. 17).
NOTE: If the unit is operated without the air filter, you will VOID the warranty.
7. Reinstall the air filter cover. Position the slots on the bottom of the air filter cover onto the tabs at
the bottom of the back plate (Figs. 17).
8. Swing the cover up until the tab on the air filter backplate snaps into place in the slot on the air filter
cover (Fig. 21).

CARBURETOR ADJUSTMENT
The idle speed of the engine is adjustable. An idle adjustment
screw is between the air filter cover and the engine starter
housing (Fig. 22).
NOTE: Careless adjustments can seriously damage your unit. An
authorized service dealer should make carburetor
adjustments.
Check Fuel
Old and/or improperly mixed fuel is usually the reason for improper
unit performance. Drain and refill the tank with fresh, properly-mixed
fuel prior to making any adjustments. Refer to Oil and Fuel Information.
Clean Air Filter
The condition of the air filter is important to the operation of the unit.
A dirty air filter will restrict air flow. This is often mistaken for an out of adjustment carburetor. Check the
condition of the air filter before adjusting the idle speed screw. Refer to Air Filter Maintenance.

Adjust Idle Speed Screw
If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed
screw as follows:
1. Start the engine and let it run at a high idle for a minute to warm up. Refer to Starting/Stopping
Instructions.
2. Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips in
between the Air Filter Cover and the Engine Cover (Fig. 22). Turn the idle speed screw in, clockwise,
1/8 of a turn at a time (as needed) until the engine idles smoothly.
Checking the fuel mixture, cleaning the air filter, and adjusting the idle speed should solve most engine
problems. If not and all of the following are true:
• the engine will not idle
• the engine hesitates or stalls on acceleration
• there is a loss of engine power

CLEANING
WARNING:
always turn your unit off and allow it to cool
before you clean or service it.
Use a small brush to clean off the outside of the unit. Do not use strong detergents. Household cleaners
that contain aromatic oils such as pine and lemon, and solvents such as kerosene, can damage plastic
housing or handle. Wipe off any moisture with a soft cloth.
STORAGE
• Never store the unit with fuel in the tank where fumes may reach an open flame or spark.
• Allow the engine to cool before storing.
• Lock up the unit to prevent unauthorized use or damage.
• Store the unit in a dry, well-ventilated area.
• Store the unit out of the reach of children.
LONG TERM STORAGE
If you plan on storing the unit for an extended time, use the following storage procedure:
1. Drain all fuel from the fuel tank into a container with the same 2-cycle fuel mixture. Do not use fuel
that has been stored for more than 60 days. Dispose of the old fuel/oil mix in accordance to Federal,
State and Local regulations.
2. Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from the
carburetor.
