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.

easily removable, so that after the floating operation, when the
concrete is sufficiently cured, they can be removed to expose the
finish blades for continued troweling.
Blades are a vital part of finishing concrete. This trowel, or

Grinding Attachments
Available grinding attachments are used for grinding surface
imperfections or joints. These attachments allow greater utilization
of your trowel. (Figure 35) illustrates a typical grinding disk
assembly, complete with hub and stone mounting plate.

Lifting Bail
There is a heavy duty, center balance type lifting bail (Figure 36)
made specifically for your trowel. These bales are ideal for lifting
and transporting your trowel. They are designed to lift the finisher
and balance it on it’s center of gravity, providing great stability
while lifting. This option is not available on electric trowel models.
Trowel Arm Adjustment Tool
If blades show uneven wear patterns or some tend to wear out
faster than others, the trowel arms may need to be adjusted.
Whiteman makes a special tool (Figure 37) that will adjust all of
the trowel arms consistently. The Trowel Arm Fixture P/N is 1817.
