Maneuvering the Trowel
1.
Get into the operator’s position behind the handle. With a
secure foothold and a firm grasp on the handles slowly
increase the engine speed until the desired blade speed is
obtained.
If your trowel has a
hand clutch (Figure 29)
, set your engine
speed with the throttle, then pull on the hand clutch lever to
start the blades turning. Adjust the blade speed after the hand
clutch is fully engaged.

If your trowel has an
electric motor
, Squeeze the micro-
switch lever ( Figure 30) to begin turning the blades. This
lever will act an
emergency stop switch
. When this lever
is released, voltage to the electric motor will be interrupted.
When this lever is squeezed the voltage will resume. This can
only be accomplished if the trowel's power ON/OFF switch
is in the ON position.

To maneuver the trowel, gently lift up on or press down on the
main trowel handle. To move the machine to the operator’s
left,
lift up
on the handle, to move machine to the right,
push
down
on the handle.
3. The best method for finishing concrete is to slowly walk
backwards (Figure 31) with the trowel, guiding the trowel
from side to side. This will cover all footprints on wet concrete.
4. Remember that if you let go of the trowel, just step away and
let the trowel come to a complete stop before trying to recover
the trowel.
The following steps are intended as a basic guide to machine
operation, and are not to be considered a complete guide to
concrete finishing. We suggest that all operators (experienced
and novice) read “
Slabs on Grade
” published by the
American
Concrete Institute, Detroit, Michigan
. Read the “Training”
section of this manual for more information.
