5. Recoil start engines:

(a) Push the decompression lever down and 

hold it while slowly pulling the recoil starter 
2 or 3 times. Do not start the engine.

(b) Pull the decompression lever up. Pull the 

recoil starter slowly and stop when there is 
resistance. This procedure closes the 
intake and exhaust valves in the 
compression position and helps prevent 
rust.

6. Electric start engines:

(a) Set the decompression lever at the non-

compression position. Do not move the 
speed control lever to the START or RUN 
position.

(b) Turn the key to the start position and turn 

the engine for 2 to 3 seconds. Do not start 
the engine.

(c) Pull the decompression lever up.

7. Drain the fuel tank or make sure it is 

completely full.

8. Protect the air cleaner, muffler and electrical 

components (dynamo, starter motor, 
switches) from water and dust.

9. Disconnect the negative (-) battery cable to 

prevent the battery from discharging.

10. Check the battery fluid and add distilled water 

as required.

11. Charge the battery once a month during 

storage.

12. Clean the engine and store it in a dry place.

RETURNING THE ENGINE TO 
SERVICE

1. Perform the Daily Checks on page 34.

2. Start the engine. Allow the engine to idle, or 

run without load if there is no idle position in 
your application, for approximately 5 to 10 
minutes while you check for:

(a) proper oil pressure.

(b) fuel, engine oil, or coolant leaks.

(c) proper operation of the indicators and / or 

gauges (if equipped).

3. Avoid prolonged operation at minimum or 

maximum engine speeds and loads for the 
remainder of the first hour of operation.
