Using The Trowel

Guiding the trowel on the slab is very simple. Get into operator’s position behind the centre of handle with good footing and apply the
throttle slowly until desired speed is obtained.
- Push handle down and machine will move to the right.
- Lift handle up and machine will move to the left.
- Slightly twist to the right and the machine will move forward.
- Slightly twist to the left and the machine will move backward.
- Holding the handle in neutral position the machine will remain stationary.

Preparation Of Concrete Surface

Use of a mechanical or air vibrating screeding machine to strike the concrete surface to level will provide good compaction to the
slab and produce an ideal surface for

nishing. It should be remembered

oating/

nishing machines will not repair or correct a poorly

screeded slab.

Floating Operation

Before starting the

oating operation be sure that the

oating blades are correctly mounted on the

nishing blades. Be aware that

with the blades turning clockwise, the

oats should be positioned the same way. The slab will be ready to work for the

rst

oating

operation when the heel of your shoes leave a print of 2-3mm on the surface of the slab. On all other

oating operations the blades

should be almost

at. After the

oated slab has set and your footprint is slightly visible, it is ready to start the

nishing operation. The

timing of all these operations is dependent on weather conditions. On average the machine will take about 10 minutes to

oat 100m2.

After each operation the engine should be stopped.
Never park the machine with the engine running, especially during the

oating operation when the concrete is relatively soft.

Considering the machine is heavy, should it be left running on the soft concrete in the same spot, this will cause damage to the

nished

oor tolerances.

Finishing Operation

After the

oating operation the

rst thing to do is to remove the

oats from the

nishing

blades and clean the blades, spider plate and protection ring of cement/concrete paste
collected during the

oating operation. Increase the blade pitch up to 10mm for the

rst

nishing operation and then continue to increase the pitch on the following

nishing operations.

Continue the

nishing passes until you obtain the desired

nished

oor surface. The

time required between each

nishing pass is dependent on the weather conditions, cement and water content of the concrete. If some

areas of the concrete set harden too fast you may apply a small amount of water with a brush to aid achieving a

nish. Be careful

when running the trowel on areas where water has been applied because the machine will tend to skate away. Be sure to maintain
control at all times.

Pitch Adjustment - Pro Trowel

The pitch control knob is in easy reach of the operator. The pitch adjustment has an unlimited pitch variation and this can be
undertaken whenever it is necessary.
During

nishing the setting up/hardening may vary from area to area across the

oor, so the pitch adjustment can be changed to suit

accurately, when required, while the machine is in operation.

Spider Plate

By experience we know the major problem on the trowel arm is lack of lubrication. During mounting we undertake the greasing and
sealing the Pro trowel arms on the spider plate, Greasing to be carried out on a weekly basis using the grease point provided. If an
arm becomes jammed, this is probably due to the arm being bent and will require replacement.

Machine Cleaning

Clean the machine after it has been used to prevent the collection of hardened cement.
Hard concrete/cement paste is very dif

cult to remove.

Changing Blades

Be sure spark plug is disconnected before changing the blades.
Make certain the machine is on a

at surface; adjust pitch control so that the blades are

at on the surface.

Never lift the machine by the guard ring.
Lift from the lifting point provided.

CAUTION

Operating Instructions

Remove bolts and lock washers on each trowel arm and remove the blades.
Before installing new blades, clean all concrete/cement from bottom and sides of the trowel; be sure trowelling edge of the blade is
behind trowel arm.
Install bolts and lock washers on each trowel arm and fasten them.

Liability
Altrad Belle.

declines any liability for possible damages to persons and / or things, which might arise from improper or wrong use of

the machine or nonobservance of the operating instructions contained in this manual.

Be careful when changing old blades for new. Due to the way the blades wear, the old blades become
very shrpe like a knife blade. As a safety precaution, wear heavy duty gloves during this operation to
prevent the hands being cut.
