2. Operation
2.1 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.

Operation CT 36-400E

2.2 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 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.
2.2.1 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.
2.2.2 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.
2.2.3 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.

18
2.4 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.
2.5 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 isolation monitor in the circuit.
2.5.1 Check that the motor On/Off switch on the trowel is in the “0” (stop)
position before connecting to a power source.
2.5.2 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.
2.5.3 This machine must be grounded while in use to protect the operator
from electric shock.
WARNING
DANGER

CT 36-400E Operation

2.6 Extension Cords
When choosing an extension cord, make sure it has adequate wire
size for safety. An undersized cord will cause a drop in line voltage
resulting in a loss of power and overheating. The table below shows
the correct wire size to use depending on cord length. If in doubt, use
the next heavier cord size. On motors being used outdoors, use
extension cords rated for outdoor use.
Improper use of extension cords can cause overheating and create
serious fire or shock hazards. NEVER use worn or damaged cords!
