Lifting
WARNING
Never leave the floats attached to the float
machine when lifting it more than 3in. off the
ground since it could detach and cause damage
to people and things
To lift the machine from one level to another use a hoisting
crane or lift truck of suitable capacity. Weight can be found
in Specifications, page 3.
Accesory lifting handles are supplied for lifting the machine
with four people.
To transport the machine on a truck place the blades in
horizontal position using the control knobs; transporting the
float machine with the blades inclined may damage the
blade tilt system.
Storage
WARNING
Never store the machine with fuel in the tank in
places where the fuel vapors might come into
contact with flames and/or sparks
If you know that the machine will not be used for more than
one month, drain the fuel from the tank in order to prevent
the formation of rubbery deposits.
Changing Trowel Blades
WARNING
Trowel blade edges may be sharp when they are
worn. Wear protective gloves when handling the
blades.
Always check the state of wear of the blades and if they are
damaged or bent, replace them. They must all be replaced
at the same time.
1. Clean the machine.
2. Slightly lift the machine off the ground (about 4”).
3. Remove the blades by removing the bolts though
arm.
Replacing The Belts
1. Changing the belts will be easier if the trowel blades
are off the ground. This can be done by lifting the
machine up and putting blocks under the guard ring
to stabilize the unit.
2. Remove belts by rolling them off the input sheave one
at a time.
Installing new belts
1. Install the replacement belts onto the clutch one at a
time and roll them into there respective groove on the
input sheave. Repeat this process for the remaining
belt.
2. Tighten tensioner bolt against idler bracket until belts
have approximately ¼ to ½" deflection with moderate
pressure applied to the back side of belts.
3. Tighten jam nut.
4. After unit is run belt tension should be rechecked and
readjusted as needed.
Replacing The Floats
CAUTION
Be careful when installing the floats: one rotor
turns clockwise and the other counterclockwise,
therefore you need to check that the various com-
ponents have been properly arranged.
1. Before mounting the floats, check that the blades are
clean. The blades must be placed in horizontal
position using the pitch control.
2. Slightly lift the float machine off the ground (about 4”).
3. Mount the floats on the blades checking the correct
direction of rotation.
4. When the floats have been mounted, reposition the
float machine on the ground.
