Operation - Samoa MP30 Parts And Technical Service Manual

OPERATION

Oil continuously passes through the metering chamber when the trigger is
pressed. The piston rotates in the metering chamber by the flow pressure. Each
oscillation of the piston equates to a given amount of fluid and makes the
output shaft rotate through the gear train.
The output shaft moves the pointer knob clockwise around the dial toward
zero, unlocking the trigger and automatically stopping the supply.
There is also a non resettable 5-digit totalizer fixed to the output shaft.
!
WARNING
Always turn pointer knob counter-clockwise.
Do not turn clockwise, severe internal damage will occur
to mechanism.
STOP MANUAL SUPPLY
To stop dispensing before reaching the pre-set volume, push down the lock
(see figure).
ZERO ADJUST
Use a Phillips head screwdriver with a 4 mm diameter or less.
Insert the screwdriver into the slot until the phillips head screw. Turn the
screw clockwise if the pointer knob stops before zero and counterclockwise
otherwise.

Perform the following procedure to start working with the preset
mechanical meter:
1. Install the preset mechanical meter in the supply line (see to previous
point "Mounting and installation section").
2. Turn the pointer knob to a non-zero amount, always rotate in the
direction indicated by the arrows of the dial (counter-clockwise). If the
pointer knob does not rotate smoothly do not force it, inspect the meter
for anomalies.
3. Open the nozzle by pulling the end.
4. To dispense oil, press the trigger until it locks. The fluid should begin to exit
the nozzle once the air trapped in the supply line is removed.
5. Check the pointer knob rotates (clockwise) around the graduated dial,
discounting the amount dispensed.
6. Check that the pointer knob stops at zero, adjust if necessary (see "zero
adjust" section).
7. Close the nozzle by pushing the end.
8. Look for leaks when meter is at rest.
9. Preset mechanical meter is ready to use.
