3. Operation
3.1 Application
This trowel is a modern, high production machine intended for floating
and finishing freshly poured concrete slabs. The machine's good
balance, adjustable handle, and easily reached controls add to
operator comfort and productivity. An automatic stop sensor provides
added operator safety. Finishing rates will depend on operator skill and
job conditions.
DO NOT use this machine for any application other than troweling
concrete.
3.2 New Machine Set-up
Trowels are shipped from the factory with the handle removed. Follow
instructions on Installing Blades and Installing and Adjusting Handles
when setting up new machines or when installing new handles and
blades.
3.3 Recommended Fuel
The engine requires regular grade unleaded gasoline. Use only fresh,
clean gasoline. Gasoline containing water or dirt will damage fuel
system. Consult engine owner’s manual for complete fuel
specifications.

CT 36 / CT 48 Operation
wc_tx000373gb.fm 17
3.4 Installing Blades
See Graphic: wc_gr003238
There are four types of blades available for the trowels. Float pans are
large "pizza pan" style blades, which hook on over finish or
combination blades and are available for the 36" machines only. Float
blades are available for all machines and clip on over finish or
combination blades. Both are used in the earliest stages of work, and
are not pitched.
Finish blades are used in the final stages of working, and are
progressively pitched to burnish the concrete.
Combination blades can be used throughout the concrete working
process. They are used in place of float blades or pans and finish
blades.
Note: Trowel blades must NOT be interchanged, i.e., do NOT put
larger diameter blades on a smaller diameter trowel.
3.4.1 Finish blades are flat on both edges and can be installed in either
direction.
When installing combination blades, orient blades as shown (a). This
positions the raised edges of the blade correctly for the clockwise
rotation of the machine.
3.4.2 Secure blades to trowel arms with screws (b). Dip threads of screws in
grease prior to installation. This will prevent concrete from cementing
the screws in place and will make removal of the blades easier later on.
3.4.3 Plug the remaining threaded holes in the blade brace with plastic plugs
(c) to prevent them from filling with concrete.
Do not lift the trowel overhead with a float pan attached, as the pan
could fall off and strike personnel working in the vicinity.

3.5 Installing and Adjusting Handles
See Graphic: wc_gr001758, wc_gr003219
On new machines the pipe handle comes assembled with the pitch
control (Twist or Pro-Shift®) (c), stop button (b), throttle (a), screws
(g), and nut (m).
To install the pipe handle assembly:
3.5.1 On machines with the foldable handle, straighten the handle and
tighten the knob (e) to secure the handle in position.
3.5.2 Pull the pitch control cable (j) from bottom end of the tube and remove
the cable nut (m) from the cable.
3.5.3 Thread the cable through the handle base (f) and over the pulley (h)
as shown.
3.5.4 Attach the pipe handle to the handle base with two M8x65 screws (g).
Torque the screws to 25 Nm (18 ft.lbs.).
3.5.5 Push the Pro-Shift® handle all the way forward (away from the
operator) OR turn the twist pitch control handle counterclockwise as far
as possible. Connect the cable to the fork (k) as shown and adjust the
cable nut so the cable is snug and the trowel blades lay flat (0° pitch).
3.5.6 Move throttle (a1) to idle position. Remove air cleaner cover. Feed
cable through clamp on recoil cover. Connect throttle cable to engine
throttle bracket by placing z-bend through hole in throttle plate. Clamp
cable into throttle casing bracket. Replace air cleaner cover.
3.5.7 Connect electrical wire on handle to both ends of the engine wire. See
handle instruction sheet for additional detail on installation.
Note: On machines with Wacker engines, do not connect wires in bag
to wires in handle.
3.5.8 On machines with an adjustable handle, position the handle by
loosening the knob (d) and adjusting the handle up or down to suit the
operator. Tighten the knob to secure the handle in position.
