(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.

(Figure
Clip-On Float Blades (Optional)
These blades will clip (Figure 33) on to an existing installed blade, allowing your finisher to float on “wet” concrete so that the troweling operation can begin as early as possible. They are 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.
Float Discs (Optional)
These round discs (Figure 34) attach to the spiders and allow the machine to “float” on “wet” concrete. The disc design allows early floating and easy movement from wet to dry areas. They are also very effective in embedding large aggregates and surface hardeners.

Finish Blades (Optional)
These blades (Figure 32) have been specifically designed for finish operations with this trowel. They will provide a premium surface finishing capability from your trowel. They should only be used after the concrete has set to the point where the trowel does not sink into the concrete when placed on it.

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.
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.

Lifting Bail
There is a heavy duty, center balance type lifting bail (Figure 36) made specifically for your trowel. These bails 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.
