OPERATION AND MAINTENANCE
4.1 GETTING STARTED
1.- Before working, make sure that all the security devices are operating under normal conditions.
2.-
WITH PETROL ENGINE:
- Read the motor manufacturer’s manual.
- Do not work in rooms with scarce ventilation.
- Make sure there is no flammable substance near to the exhaust.
Check the petrol level in the fuel tank (unleaded gas only).
Check the oil reservoir of the motor is full (see engine’s manual) in the 4 stroke engine
(SAE10W40).
3.-
WITH ELECTRIC MOTOR:
Before working, switch the motor off with the handle switch.
Check the Current specifications of the power source.
Make sure the cables are in good condition.
Secure the power source is ground connected.
In the case of using extension cables, read the section 4.2.
4.- Check all the bolts are well tighten. The
bolts that fix the clamps to the beam must be
strongly tightened up with a n
er
22 wrench:
5.- Start the motor, regulate the speed with
the accelerator (Petrol) until it reaches a
good vibration.
6.- Vibrate the floor by pulling the screed
from the pulling handles.
7.- When the work is finished, always
remove the fresh concrete that has been
settling on the beams and the motor before it
gets dry.
8.- When a defect or a malfunction has been detected, endangering the use of this machine or not,
stop the work and make the correspondent maintenance to avoid any danger or bigger damage.
4.2 EXTENSION CABLES
In order to protect the operator from an electric shock, please make sure that the screed is ground
connected.
The motors are fitted out with 3 ways cables (2 Earth) and the correspondent plug. The
convenient socket must be used.
Do not use damaged cables.
Avoid heavy loads on cables
To determine the transversal section, follow the following procedure:
Procedure to determine the necessary transversal section in cable extensions:
Do the following verifications and take the highest section of cable:
1.- The ohmic resistance and inductive resistance of the cable with the permitted loss of voltage of
2%,
cos
= 0.8 through the frequency and voltage curve.
I.e.:
Nominal voltage:………………… 1- 230 V 50 Hz
Nominal current:…………………... 10 A
Cable length:………………………. 100 m
Entering the curve with the product: Intensity x Length = 10 x 100 = 1000 A m.
We obtain a 4 mm2 section.
