Operations
TO START--
Make sure the Dyna-Clutch lever
is in the STOP position. If it is not, push the
lever down to the STOP position before at-
tempting to start the engine. Open fuel valve
under fuel tank (if so equipped), open throttle
approximately half way down and apply choke.
Holding unit handle firmly with one hand, pull
the starter rope sharply with the other about (3)
times. When engine starts, open choke and
adjust throttle as necessary to keep it running. If
engine doesn't start after (3) pulls, open choke
slightly.
NOTE: These starting instructions are general
guidelines only. Since many engine options are
available on CF Power Trowels, consult the
ENGINE MANUAL included with the unit for
specific instructions.
TO SHUT OFF
5.5 HP & 8 HP B&S ENGINES - close throttle
all the way, flip grounding tab against spark plug
and hold there until the engine comes to a
complete stop.
4, 5.5, 8, 11 and 13 HP HONDA ENGINES -
close throttle all the way and flip oil minder kill
switch to the OFF position.
4.5, 6, 9 & 11.5 HP ROBIN ENGINES - close
throttle all the way, depress kill switch button
and hold down until engine stops completely.
NOTE: These stopping instructions are general
guidelines only, consult the ENGINE MANUAL
included with the unit for specific instructions.
INITIAL OPERATION
--With engine started
as instructed previously and at operating tem-
perature, adjust speed to about half throttle.
Hold the handle firmly with one hand and move
the Dyna-Clutch lever to RUN position to
engage the trowel blades.
FLOATING OPERATION
Attach float or combination blades to the trowel
arms, and when the concrete has set sufficiently
to support the weight of the trowel, place the
unit on the concrete. Start the unit and engage
the blades as previously instructed. Using the
tilt adjustment knob or ProPitch™ handle,
adjust the blades to the float position--blades
should be as flat to the concrete as possible with
enough tension kept on the tilt adjustment cable
to prevent the unit from dancing or chattering.
Guide the trowel over the concrete in a circular
back and forth motion. Under normal condi-
tions, you should be able to float a 30 x 30 foot
area in approximately 15 minutes.
This operation will bring the water and fines to
the surface, allowing for a smoother finish when
finishing the concrete.
FINISHING OPERATION
After floating, allow the concrete to set until it
will support the weight of the trowel. Set the
pitch to approximately 1/4" to 3/8" on the
blades. If the blades start to dig into the con-
crete, decrease the amount of pitch.
