OPERATION
Blade Pitch
Sometimes it may be necessary to match blade pitch
between the two sets of blades. There are some signs
that this may be necessary. For example, the differences
in pitch could cause a noticeable difference in finish quality
between the two sets of blades. Or, the difference in blade
pitch could make the machine difficult to control. This is
due to the surface area in contact with the concrete (the
blade set with the greater contact area tends to stick to the
concrete more).
Matching Blade Pitch for Both Sets of Blades
Trowels equipped with Twin Pitch
TM
Controls may need to
have blade pitch between the two sets of blades
"syncronized". If the blades need to be syncronized this is
easily accomplished by performing the following. Refer to
Figure 12.
1. Lift the pitch adjustment handle on either side. Once
lifted, that side is now disconnected from the Twin
Pitch
TM
system.
2. Adjust to match the opposite side.
3. When adjusted, lower the handle to Twin Pitch
TM
operating position.
CAUTION
When turning an adjustment handle, do not force it to
turn or damage to the cable may occur. If the cable
starts to noticeably twist this is a good indication that
one side is either all ready at full pitch or it is bound up
due to concrete, debris, or corrosion.
