What is the difference between a concrete and a plaster mixer?

A concrete mixer is used to mix thick mixes that may contain rocks, sand and cement better called concrete, Concrete may be used for setting posts, pouring concrete foundations and slabs. Any mix that uses rock or other course aggregate is best prepared in a concrete mixer.
The plaster mixer, or mortar mixers is used to mix exterior stucco, interior plaster or mortar for brick, block, floor tile, etc., and any mixes that “do not contain rock, gravel or any other aggregates”.

Is there anything in particular about gasoline engines that I should know?


The fuel valve should always be turned to the OFF position before towing the mixer. If you fail to do this, the engine cylinder may fill with gasoline making the engine unable to start. To clear this, it may be necessary to remove the spark plug from the engine with a spark plug wrench.
Also, all mixers are shipped with no fluid (gas & oil) please do not run the engine before checking the levels.


Pull the starter cord several times to force the raw fuel from the piston chamber.
Replace the spark plug wire.
Start the engine by using the usual procedure.
In addition, check the oil in the crankcase. It may have become contaminated with fuel and would need to be replaced.
