4.8. OPERATING CONDITIONS WITHOUT RELEASING WATER
Operating the pump without releasing the water for long
periods (no waterflow pressure - for example, due to a twisted
hose because of nozzle changes or additional hoses) will cause
overheating and possible damage to the seal and components.
That’s why the BP4 motor pump is equipped with an electronic
cut-off to prevent damage due to a fuel loss.
NOTE 1: There is no manual reset to re-start the motor and no
need for adjustment.
NOTE 2: Only use original spare parts when servicing the
motor. Do not replace components as this could affect the
operation and automatic cut-off system criteria.
4.7. FUEL BLENDING ADJUSTMENT SCREWS (CARBURETOR ADJUSTMENT)
The carburation must be adjusted only by specialized
personnel.
A quick carburation analysis may be done by checking the
spark plug color. To do so, turn off the motor after having been
on and loaded for a few minutes.
Remove the spark plug by unscrewing it with the right wrench
and check the color of the porcelain, which should be light
brown.
If the spark plug electrode is a light color, the carburation
is poor; if the motor is used in these conditions, it could be
damaged. Do not use the motor in these conditions and check
with an authorized distributor for adjustment.
CAUTION: Take the greatest of care when adjusting
the high-speed blending screw (needle). If it is adjusted
incorrectly, the motor may be damaged due to
overheating.
4.9. OPERATING IN A COLD CLIMATE
The pump may operate at below-zero temperatures if certain
precautions are taken to prevent the formation of ice in the
pump.
1. After filling the pump, the unit must operate at low-speed
for a short period of time to allow all components to heat up
before continuing with the remaining operational procedures.
2. Unless a heater is available, drain the pump of all water if
not used for a prolonged period. The motor unit / starter must
rotate a few times to ensure all water has been drained from
the pump. Drain the pump filling line if a filler was used.
3. After using, drain all the water from the pump, collectors
and lines. You can also pour a little anti-freeze into the pump
and have it circulate through the pump and pipe system.
