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, 3Ø

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.
