Spark Plug Maintenance
The spark plug is essential for proper engine operation. The spark plug should be intact, free of deposits, and properly gapped. A bad or incorrectly
installed spark plug can cause engine damage.
To inspect the spark plug:
1. Remove the spark plug by pulling on the spark plug cap. (See Figure 9a.)
2. Unscrew the spark plug by using the included spark plug wrench.
3. Visually inspect the spark plug. If it is cracked and/or chipped, discard and
install a new spark plug.
E5T, BM4A, BMR4A (NGK)
is recommended.
4. Measure the spark plug electrode gap with a gauge. The gap should be (0.6-0.7mm). (See Figure 9b.)
5. If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base and then re-gap the spark plug.
6. Screw the spark plug back into place by using the included spark plug wrench.
7. Replace the spark plug cap.
Emptying the Fuel Tank
To store for extended time, drain the gasoline from the fuel tank. To drain gasoline:
1. Turn the fuel valve to the “off” position.
2. Remove the fuel filter cup. (See “Fuel Filter Cup Cleaning” earlier in this section.)
3. Empty the fuel filter cup of any fuel.
4. Place a receptacle underneath this engine to catch gasoline as it drains.
5. Turn the fuel valve to the “on” position and allow all gasoline to drain.
6. Turn the fuel valve to the “off” position.
7. Replace the fuel filter cup.
8. Store the drained gasoline in a suitable place.
STORAGE/TRANSPORT PROCEDURES
Never place any type of storage cover on this cement mixer while it is still hot. Do not store gasoline for more than 3 months.

• Turn the fuel valve to the “off” position.
• Disconnect the spark plug.
• Do not obstruct any ventilation openings.
