CT 36 / CT 48 Safety Information

1.4 Service Safety

Poorly maintained machines can become a safety hazard! In order for
the machine to operate safely and properly over a long period of time,
periodic maintenance and occasional repairs are necessary.

WARNING

1.4.1 DO NOT attempt to clean or service the machine while it is running.
Rotating parts can cause severe injury.

1.4.2 DO NOT crank a flooded engine with the spark plug removed on
gasoline-powered engines. Fuel trapped in the cylinder will squirt out
the spark plug opening.

1.4.3 DO NOT test for spark on gasoline-powered engines if the engine is
flooded or the smell of gasoline is present. A stray spark could ignite
the fumes.

1.4.4 DO NOT use gasoline or other types of fuels or flammable solvents to
clean parts, especially in enclosed areas. Fumes from fuels and
solvents can become explosive.

1.4.5 DO NOT remove blades while the machine is hanging overhead.

1.4.6 ALWAYS support the machine securely before changing blades.

1.4.7 ALWAYS keep the area around the muffler free of debris such as
leaves, paper, cartons, etc. A hot muffler could ignite the debris and
start a fire.

1.4.8 ALWAYS replace worn or damaged components with spare parts
designed and recommended by Wacker Corporation.

1.4.9 ALWAYS disconnect the spark plug on machines equipped with
gasoline engines, before servicing, to avoid accidental start-up.

1.4.10 ALWAYS keep the machine clean and labels legible. Replace all
missing and hard-to-read labels. Labels provide important operating
instructions and warn of dangers and hazards.

1.4.11 ALWAYS handle blades carefully. The blades can develop sharp
edges which can cause serious cuts.

2.4 Sound and Vibration Data

The required sound specification, Paragraph 1.7.4.f of 89/392/EEC
Machinery Directive, is:

• the sound pressure level at operator’s location (L

• the guaranteed sound power level (L

) = “B” dB(A)

WA

) : “A” dB(A)

pA

These sound values were determined according to ISO 3744 for the
sound power level (LWA) and ISO 6081 for the sound pressure level
(LpA) at the operator’s location.

• The weighted effective acceleration value, determined according to
ISO 8662 Part 1, is: “C” m/s2.

The sound and vibration specifications were obtained with the unit
operating on wetted and cured concrete at full engine speed.

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

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 nut 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 (m) 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.
