4. Operation
4.1 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 Operator Present Lever 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.
4.2 New Machine Set-up
Trowels are shipped from the factory with the handles and blades
removed. Follow instructions on
Installing Blades
and
Installing and
Adjusting Handles
when setting up new machines or when installing
new handles and blades.
CT 30EDT / CT 36EDT Operation
wc_tx000249gb.fm 16
4.3 Installing Blades
See Graphic: wc_gr001097
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 30" and 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, which are supplied with the machine, 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.
4.3.1 New machines are supplied with finish blades as standard equipment.
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.
4.3.2 Secure blades to trowel arms with 1-1/2" 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.
4.3.3 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.

4.4 Installing and Adjusting Handles
See Graphic: wc_gr001171
Pipe Handle:
On new machines the pipe handle comes assembled with the pitch
control (h).
To install the pipe handle assembly:
4.4.1 Pull the pitch control cable (d) from bottom end of the tube and remove
the nuts from the cable.
4.4.2 Thread the cable through the handle base (a) and over the pulley (c)
as shown.
4.4.3 Attach the pipe handle to the handle base with two M8x16 screws (b).
Secure the screws using Loctite 243 or an equivalent medium-strength
threadlocking compound. Torque the screws to 22 Nm (16 ft.lbs.).
4.4.4 Turn the twist pitch control handle counterclockwise as far as possible.
Connect the cable to the fork (e) as shown and adjust the cable nuts
(f) so the cable is snug and the trowel blades lay flat (0° pitch).
Steering Handle:
4.4.1 Install steering handle (g) to machine as shown. Secure shoulder bolt
(k) using Loctite 243, or equivalent.
4.4.2 Route the power cable and the Operator Present Lever cable through
the inside of the tube welded to the underside of the pipe handle.
4.4.3 Run the Operator Present Lever cable through the handle, in through
hole (j) and out through hole (o).
4.4.4 Mount the Operator Present Lever (n) as shown. Be sure that tabs on
lever dig through paint and into metal of handle, when installing. This
will insure a good electrical ground. Test function of lever prior to using
trowel by starting trowel and disengaging lever—trowel should stop
promptly. See
To Start
.
4.4.5 Position handle by loosening knob (m) and adjusting handle up or
down to suit operator. Tighten knob to secure handle in position.

4.5 Installing Plugs and Power Cords
See Graphic: wc_gr0001177
The trowel comes with a 5-prong plug for connecting to 400V,
power.
To reduce the risk of electric shock, only a certified electrician should
install or service power plugs, cords, or electrical boxes.
4.6 Connecting to Power Supply
To reduce the risk of electric shock, all equipment must be properly
grounded. Connect this trowel to grounded receptacles and extension
cords only. Make sure power supply has either an Earth Leakage
Circuit Breaker (ELCB) or an isolaton monitor in the circuit.
4.6.1 Check that the motor On/Off switch on the trowel is in the “O” (stop)
position before connecting a to power source.
4.6.2 Make sure the power supply matches the voltage requirements listed
on motor label. Running the trowel at a low voltage will cause it to run
slow. This will reduce performance and cause the motor to overheat.
4.6.3 This machine must be grounded while in use to protect the operator
from electric shock.
