CMG5 2.5 Cu Ft. Cement Mixer 9
Changing/Adding Oil
The oil level should be checked before each use. (See Figure 8.) When the oil level is low, add oil until the level is sufficient to operate.
Oil Capacity (fluid oz./L)
15.2 ounces (0.45 liters )
Oil Type Recommended
SAE10W-30
To drain the oil:
It is necessary to drain the oil from the crankcase only if it has become contaminated with water and/or dirt.
1. Place a bucket underneath to catch oil as it drains.
2. Unscrew the oil drain plug located on the crankcase underneath the oil filler/dipstick cap.
3. Allow all the oil to drain.
4. Replace the oil drain plug and tighten.
NOTE: Never dispose of used motor oil in the trash, down a drain or on the ground. Put oil in a sealed container and contact your local
recycling center or auto garage to arrange oil disposal.
To add oil to the engine crankcase:
1. Confirm that the cement mixer is on a level surface.
2. Unscrew the oil filler/dipstick cap from the engine as illustrated in Figure 8 below.
3. Using a funnel, add high detergent motor oil to fill the engine crankcase to the correct quantity. SAE10W-30 oil is recommended for general use.
When the engine crankcase is full, the oil level should reach the lower lip of the oil filling opening as shown in Figure 8.
Oil Capacity (fluid oz./L)
20 / 0.59
Oil Type Recommended
High Detergent Motor Oil, SAE10W-30
Air Filter Maintenance
Routine maintenance of the air filter helps maintain proper airflow to the carburetor. Occasionally verify that the air filter is free of excessive dirt.
The air filter will require more frequent cleaning when operating in extremely dusty areas.
To clean air filter, remove from engine. Wash in kerosene. Pour motor oil on filter, squeeze out excess oil and reinstall in the engine.
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.
