(Figure 30) below illustrates a typical walk-behind trowel
application. Practice maneuvering the trowel. The trick is to let
the trowel do the work.

Continue to practice maneuvering the trowel. Try to practice as if
you were finishing a slab of concrete. Practice edging and
covering a large area. Remember a good finishing technique is
to work backwards. Be careful when moving backwards so that
hazards can be avoided. The best way to get accustomed to the
trowel is repeated use.

NEVER place your 

feet or hands inside the guard

rings while starting or operating this equipment.

ALWAYS  keep clear of 

rotating or moving parts

while operating this equipment.
