1.10 New Machine Set-up
Trowels are shipped from the factory with the handles and blades removed. Follow Sections 1.11 Installing Blades and
1.12 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.

1.11 Installing Blades
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 avail-
able for all machines and clip on over finish or combina-
tion 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 con-
crete 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.
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 (r). This positions the raised edges of the blade
correctly for the clockwise rotation of the machine.
2. Secure blades to trowel arms with 1-1/2" screws (s).
Dip threads of screws in grease prior to installation.
This will prevent concrete from cementing the screws
in place and make removal of the blades easier later
on.
3. Plug the remaining threaded holes in the blade brace
with plastic plugs (t) to prevent them from filling with
concrete.
WARNING
Do not lift the trowel overhead with a float pan
attached, as the pan could fall off and strike person-
nel working in the vicinity.

1.13 Application
This trowel is a modern, high production machine in-
tended 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 combi-
nation 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.
1.16 Before Starting
Before starting trowel, check the following:
- oil level in engine
- oil level in gearbox
- fuel level
- condition of fuel lines
- condition of air filter
- condition of trowel arms and blades
- pages 6 and 7 of manual for label descriptions
1.17 Run/Stop Switch
The Run/Stop Switch (b) is located on the pipe handle.
When the switch is placed in the I (run) position (b
1
), the
engine may be started and the trowel operated. When the
switch is placed in the O (stop) position (b
2
), the engine
will not run and the trowel stops.
To prevent uncontrolled spinning of the trowel, the Run/
Stop Switch is also designed to automatically close under
certain conditions and shut off the engine. For example,
if the operator loses his/her grip on the trowel, the
centrifugal force created by the spinning machine will pull
the switch to the O position, stopping the trowel.
1.14 Recommended Fuel
The engine requires regular unleaded gasoline. Use only
fresh, clean fuel. Fuel containing water or dirt will
damage fuel system. Consult engine owners manual for
complete fuel specifications.
