Figure A shows the pump's
vent plug, which should be
screwed
onto
the
red
transport plug (B) located on
top of the pump housing. The
transport plug is only for
transport
and the device
must not be used without
replacing it with the vent
plug!
Replace the red plug with a
black
plug+
extension
(located in the bag attached
to the pump) before using it
the first time.
Safety data:
The pump is filled with 15W40
class SF oil at an amount of
100ml. Before starting, it is
necessary to check the oil
level in the pump gauge
(Figure C). To check the oil
level, place the pump in a
horizontal position. Otherwise
it will not match the level of
the recorded facts. The oil
level must be within the required range during operation to ensure complete lubrication of the internal
components. Unscrew the plug and extension. Take black plug with scale, insert it into pump body opening and
check the oil level. It must be between the slots on the stem scale. Risk of permanent damage to the device!
Reinstall pump vent extension and close it with black plug with scale.The operation of a pump with a low oil level
or without oil filling will cause permanent damage to the pump and void the warranty. Check the oil level before
each use!
If it is necessary to add oil in the pump, use only oil class: 15w40 SF-SJ. Do not exceed the
maximum oil level! This can result in damage to the shaft seals and oil leakage from the pump.
Running
the pump without water or when it’s dry causes permanent damage to the pump and voids the warranty. Check
the water inlet before each use! Due to optimum lubrication, the pump must be at a maximum incline of 15° from
the horizontal plane.
Regulation of output water pressure
This pump allows the water outlet pressure to be controlled in the range of 80 bar to 220 bar. To change the
pressure, it is necessary to turn the controller located on the pump (Figure C - Pressure). The rule is: looking
from above and turning TO THE RIGHT (clockwise), the pressure increases and turning TO THE LEFT reduces
the pressure. Increasing the pressure increases the load on the motor and fuel consumption as well. That is
why it is suitable to adjust the water pressure according to the specific situation. Reduce the pressure to extend
the service life of the motor and pump.
Pump maintenance
The oil in the pump is replaced after the first 30 hours of operation and every subsequent 100 hours of
operation.
Use
15w40 SF-SJ
oil class for the change. Drain the oil from the pump by releasing the plug located
on the bottom side of the pump. It is advisable to replace the oil after use when the oil is warm, when it’s easier
to drain and impurities are dispersed in oil. After draining the old oil, screw the drain screw back slowly, pour the
oil slowly through the opening of the vent plug and at the same time check the oil level located on the side of
the pump. Take care that the oil flows slowly inside the pump, it can easily overflow. After reaching the required
oil level screw the vent plug and oil stopper back into the pump cover.
