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

sound power level (L
WA
) and ISO 6081 for the sound pressure level
(L
pA
) at the operator’s location.
The weighted effective acceleration value, determined according to
ISO 8662 Part 1, is: 3.71 m/s
2
for units with wing grip handle; 2.94 m/
s
2
for units with bicycle-style handle.
The sound and vibration specifications were obtained with the unit
operating on wet concrete at nominal engine speed.

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.
