Electrical Connection; Direction Of Rotation Of Motor; Use Of The Machine; Working Environment Conditions - Butler NAV11 Manuel D'instructions

Proceed as follows:
•
drill four 12-mm holes matching up to the holes in the machine frame.
•
insert the screw anchors.
•
install the machine so to match holes drilled in the floor. Tighten the screws at 70 Nm.
BEFORE STARTING THE MACHINE, FILL THE HYDRAULIC SYSTEM WITH ONE OF THE
RECOMMENDED LUBRICANTS (SEE PAR. 5.2). FILL UP UNTIL THE SIGHT GLASS IS
COMPLETELY COVERED (SEE PAR. 5.1).
3.3

Electrical connection

THE ELECTRICAL SYSTEM MUST BE SERVICED BY SKILLED ELECTRICIANS ONLY.
Before connecting the machine:
• make sure that the power mains rating corresponds to the machine rating as shown on the machine plate;
• check that all power mains components are in good condition;
• check that the electrical system is properly grounded (earth wire must be the same cross-section area as the
largest power supply cables or greater);
• make sure that the electrical system of the workshop features an overload/short-circuit cutout set at 30 mA.
Insert the machine cable in the provided hole A (Fig. 28) and insert the wires in the terminal board as indicated.
Fit a type-approved plug to the machine cable (the earth wire is yellow/green and must never be connected to the
phase leads).
Make sure that the electrical system is compatible with the rated power absorption specified in this
manual and apt to ensure that voltage drop under full load will not exceed 4% of rated voltage (10%
upon start-up).
3.4

Direction of rotation of motor

Once all power connections have been made, turn on the machine by means of the main switch.
Make sure that the pump is running in the direction shown by the arrow on the motor and the wheel-carrier
chucking table is rotating in the direction that is shown on the control.
If the direction of rotation is wrong, swap two phase wires in the plug (e.g., the blue and brown wires).
FAILURE TO OBSERVE THE ABOVE INSTRUCTIONS WILL IMMEDIATELY INVALIDATE THE
WARRANTY.

USE OF THE MACHINE

4.1

Working environment conditions

The machine must be operated under proper conditions as follows:
•
temperature:
•
relative humidity:
•
atmospheric pressure:
The use of the machine in ambient conditions other than those specified above is only allowed after prior
agreement with and approval of BUTLER S.P.A.
4.2

Work position

Fig. 2 (NAV 11 - R926), Fig. 4 (NAV 21 - B956) and Fig. 6 (NAV 31 - B957) show work positions A, B, C, D which
will be referred to during the description of the machine operating phases. Positions A and B are the main positions
for wheel fitting and removal with the chucking table, while positions C and D are ideal for tyre insertion and
removal and for moving the control levers.
Working in these positions allows better precision and speed during operating phases as well as greater safety for
the operator.
