3.1 Power to the trowel
The power must be supplied to the trowel as described in the BARIKELL handbook. For safety
keep the following points in mind:
- The engine is an air-cooled gasoline engine.
The trowel can be equipped with different types of engines as indicated in the technical
details. The engine is started by rope start. The fuel is gasoline, and is conveyed from the
tank to the carburettor after flowing through a filter.
- The rotation of the blades is transmitted from the engine to a centrifugal clutch, connected by a
V-belt to the gearbox of the rotor.
3.2 Safety precautions for t he operator
Never start any maintenance or repair while the engine is still running or hot. Be sure the spark
plug is disconnected.
Make sure that nobody stands near the trowel when operating. To avoid unexpected contact with
the rotating parts it is recommended to keep a minimum distance of 2 meters from the operator and
the trowel.
Before every working day check the trowel thoroughly, and pay special attention for loose bolts and
nuts. Be sure that the deadman switches on the trowel are working correctly.
Use the trowel always on a flat level surface.
Do not wear untied clothes, bracelets or other flying objects during the working cycle.
Always wear protective devices such as gloves, safety helmet, safety shoes and others which
conform to the safety regulations.
To avoid slipping and loss of control of the trowel, when starting the engine,
the operator must always maintain good footing. Be sure to maintain
control at all times, to avoid possible damage or operator injury.
Be careful when changing old blades for new. Due to the way the blades
wear, the old blades become sharp like razor blades. Always wear heavy
duty working gloves during this operation and pay special attention to the
position of the blades.
Keep hands and feet away from rotating parts and make sure all safety
protection is in place.
When finishing concrete above ground level or on floors with holes larger
than 20x20cm, barriers should be installed as a protective measure. The
barrier should be such that it will stop the trowel from riding over the edge
of the slab in case of loss of control.
Never lift the trowel by the rotating ring; use the lifting handle provided on
the trowel.
Exhaust fumes are harmful. Always operate in well illuminated and
ventilated areas.
