Pitching The Blades - Quick Pitch Handle

"Quick Pitch™"
handle
, (Figure 17) simply squeeze the trigger lock
and pull the handle towards the operator. Pushing the
handle towards the engine will cause the blades to lay
flat.

2. 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.
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.
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.
Set 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.

3. The best method for finishing concrete is to slowly walk
backwards (Figure 19) 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.
5. Check the manual clutch occasionally for proper operation.
Checking operation of the manual clutch at the beginning of
operation and periodically serves as a safety check verifica-
tion.
