1.The warranty is valid 1 year after the purchasing of the machine, The warranty will cover parts with
manufacture`s defects. In any case the warranty will cover a malfunction due to improper usage of
the equipment.
2.In all warranty requests
AUTHORIZED SHOP, always including the complete address and name of the consignee.
3.The Technical Assistance Service will immediately notify you if it accepts the warranty and if
requested, it will send a technical report.
The warranty will be void if any equipment has been previously handled by personnel outside of
ENARCO, S.A. or not authorized by it.
NB:

11 RECOMENDATIONS OF USE OF CONCRETE VIBRATOR

1.Choose the type of vibrator adequate to the dimensions of the structure to vibrate, the distance
among the reinforcement and the slump cone. It is recommendable to have an additional concrete
vibrator.
2.Before starting check that the concrete vibrator is in good use and it works correctly. Use the
means of safety and protection.
3.Pour the concrete in the structure avoiding high heights. Try to pour levelled the concrete. The
thickness of every layer should be less than 50 cm, it is recomendable between 30 and 50 cm.
4.Introduce the vibrator vertically in the concrete mass without moving it horizontally. Do not use the
vibrator to push the concrete horizontally. The concrete vibrator should be introduced into the mass
at regular intervals. The interval should be from 8 to 10 times the diameter of the poker. See the
concrete in the process of vibrating to determine the field of action of the vibrator. This field should
en
be overlapped to avoid areas without vibrating. To obtain an optimum compacting of the concrete,
plunge it 10 cm into the precedent layer to assure a good adherence. The time in vibrating the
different layers should not be big to avoid cold joints. Do not push or force the vibrator into the mass,
it could be stuck in the reinforcements.
5.The time of vibration in each point depends on the type of the concrete, the size of the vibrator and
other factors. This time can be from 5 to 15 seconds after the immersion in each point. The time is
shorter for a fluid mass, a vibration in excess can produce segregation. It is considered the concrete
to be well vibrated when the surface around the poker is shiny and compact and there is no more air
bubbles, as well a change in the noise of the vibrator is produced. So much defects in structures are
produced due to perform the vibration in an unmethodically way and in a hurry.
6.Do not push or force the vibrator against the reinforcement. Keep a distance of 7 cm minimum
from the walls.
7.Always remove the poker vertically with movements upwards and downwards so the concrete fills
the empty space again. Do not switch off until you stop the vibration completely. Se speed of
removing is approximately 8 cm per second. When the vibrator is nearly out extract quickly to avoid
shaking the surface.
8.In order to vibrate slabs, the poker has to be kept oblique so that the contact superficy with mass is
bigger and the compacting effect is better.
9.Do not keep the concrete vibrator out of the concrete during long periods. If you do not continue
vibrating stop it.
10.Follow the maintenance instructions.
The concrete has to be carefully prepared to get the best effects of the vibration in terms of consistency and
resistance
