D1 Detailed information on the METER
Handle
An external shock-resistant plastic cover contains all the
components of the METERand provides an ergonomic handle.

means of four cross-head screws.
The user can easily access this pack to
replace the batteries.
Swivel and filter

Meter
The keypad is of membrane type
and is equipped with 5 keys.
To guarantee an accurate measurement
of the dispensed amount the METER
uses the principle of the oval gears.
Multi-position extension
To guarantee an easy use, the METERis
equipped with a multi-position
extension. It can be positioned by the
operator within a 75° range.

E2 Line pressure relief
This operation is to be carried out to
replace the pre-existing nozzle with the
METERnozzle or to dismount the
METERfor maintenance purposes.
Warning
Failure to carry out this line pressure
relief procedure may cause damage
to persons or things.
ij By means of two wrenches, unscrew
from the swivel.
ij Close the shut-off valve. Otherwise
stop the power supply pump and make
it unserviceable to avoid an accidental
re-start during maintenance operations.
ij Operate the valve of the nozzle to be
replaced (or of the METERto be
disassembled for maintenance reasons)

order to release the line pressure.
Warning
Be careful to collect any oil leakage
into a suitable container.
Warning
If a dripless valve is installed at the
end of the nozzle, the pressure inside
the line will not decrease to zero, but
it may stay at a value of 0.2 - 0.5 bar
according to the type of dripless
valve used.

only) Remove the rubber cover from its
coupling on the swivel and move it

E3 Flushing the lines
Flushing the lines means to let a given
amount of oil flow trough them so as
to ensure a proper "washing" of the
whole system, a correct cleaning and
the absence of dirt, contaminated
material or processed waste inside the
lines before installing the nozzle.
The flushing procedure depands on the
type and features of the system and
must be carried out by trained and
qualified personnel in compliance with
the procedures set down by the
installer.
Warning
The flushing operation must be carried
out on all lines, upstream the nozzle. In
case the system is equipped with more
than one nozzle, flush the lines which
supply the nozzles farthest away from
the supply the nozzles situated
nearer the pump.
This operation is absolutely
necessary with NEW INSTALLATIONS
or if the lines used are contaminated.
You need not carry out this
procedure when replacing the nozzle
in use.
E4 Preliminary checks of the METER
Make sure that the threaded end fitted
on the flexible hose is suitable for the
swivel of the METER provided with:
Female thread 1/2" BSP
or
Female thread 1/2" NPT
ij Check that the METERto be installed
is complete and in good condition,
making sure that the filter is clean and
correctly installed (see paragraph “H2”).
Filter
16
The filter of the METER, characterized by
a large filtering surface, has been
designed to guarantee a correct filtering
and a low pressure loss.
To remove and re-install the filter refer
to paragraph “H2”
Warning
The absence of the filter or its
improper installation may cause the
meter or the METER valve to block if
dirt is present in the tubes. This
situation may occur especially during
new installations.
To solve these problems consult a
qualified Service Centre

All of them are equipped with an
automatic dripless valve.
All extensions are equipped with a rigid
ending part (external ? 12 mm, 3/8"G
nut) suitable for being easily connected
to the METERwithout using any sealant.

ij To start dispensing:
Pull the trigger
completely and then
release it.
The trigger thus
remains locked in
open position. Now
dispensing can
continue even if the
Operator is not
present.
ij To stop manually dispensing in
progress:
Pull again the trigger completely and
then release it.
ij The dispensing operation can be
resumed in AUTO mode within a given
time (TIME OUT) from the stop. Within
this TIME OUT the METERstill allows the
locking of the trigger in open position.
ij After this TIME OUT the METERstill
allows the user to continue the
dispensing but only in MANUAL mode.
Manual resumption of the
dispensing (TOPPING UP):
Once dispensing has been carried out in
AUTO mode, the METERallows the user
to continue the dispensing operation, if
necessary.
Warning
Some time after the automatic stop of
dispensing, the METER2)
lights up and dispalys the preset
quantity and the value.
To carry out the TOPPING UP, DO
NOT type RESET and pull the trigger.
The dispensed amount is added to the
previous one in AUTO mode.
The PRESET value previously set,
displayed in the Total, starts blinking to
indicate that the pre-set value has been
exceeded.
Automatic stop:
The supply automatically stops when
the pre-set value is reached. The AUTO
message disappears from the LCD.

To clean or replace the filter:
Warning
A. Release the line pressure and
dismount the METER in compliance
with the instructions given in paragraph
E2.
- Do not use filters which have
been damaged during improper
dismounting or cleaning
operations.
- Always reposition the filter with
the utmost care.
If the filter is in good condition
and is correctly installed, it
guarantees the good operation
of the METER, thus avoiding any
dust or foreign bodies, which
may lock or damage the METER
valve.
B. Unscrew the 1/2_ nut and remove
the filtering disk.
C. Properly clean the filter or use a
new filter (see Spare parts list in
paragraph M3).
D. Place the filter again, paying
attention to components’ positioning.
E. Reassemble the METER
according to the instructions given in
paragraph E6.
F. Fix the connection again and
tighten it at 20 Nm.
