2.1 Laws Pertaining to Spark Arrestors

Notice: State Health Safety Codes and Public Resources Codes

specify that in certain locations spark arresters be used on internal

combustion engines that use hydrocarbon fuels. A spark arrester is a

device designed to prevent accidental discharge of sparks or flames

from the engine exhaust. Spark arresters are qualified and rated by

the United States Forest Service for this purpose.

In order to comply with local laws regarding spark arresters, consult

the engine distributor or the local Health and Safety Administrator.

2.2 Operating Safety

Familiarity and proper training are required for the safe operation of

equipment! Equipment operated improperly or by untrained personnel

can be dangerous! Read the operating instructions contained in both

this manual and the engine manual and familiarize yourself with the

location and proper use of all controls. Inexperienced operators should

receive instruction from someone familiar with the equipment before

being allowed to operate the machine.

2.2.1 NEVER allow anyone to operate this equipment without proper

training. People operating this equipment must be familiar with the

risks and hazards associated with it.

2.2.2 NEVER touch the engine or muffler while the engine is on or

immediately after it has been turned off. These areas get hot and may

cause burns.

2.2.3 NEVER use accessories or attachments that are not recommended by

Wacker. Damage to equipment and injury to the user may result.

2.2.4 NEVER leave machine running unattended.

CT 36/48 AVT/AVP Operation

wc_tx000245gb.fm 17

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 automatic Run/Stop Switch, or a

combination of an automatic Run/Stop Switch and an Operator

Present Lever, provide 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.

Note:

Steering handles come in two styles: a bicycle style grip or a

wing grip. Assembly procedures are identical for both styles.

4.3 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.

Operation CT 36/48 AVT/AVP

wc_tx000245gb.fm 18

4.4 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.

4.4.1 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.

4.4.2 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.

4.4.3 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.
