4. Surface of device should be wiped regularly with towel or wiping cloth to keep
the cleanness.The device should be stored in cool and dark place free of direct
sun shining.
Important notice
1. The device can be operated only by trained qualified personnel.
2. Never to smoking nearby the device.
3. 60~100 is suitable for the temperature of waste engine oil pumped by the
device. Density of engine oil under the above temperature is about 1.3 times
more than water’s, therefore the flow velocity of oil is slower than water’s. case
such as failure pumping or slow flow are possible in case of the temperature
lower than specified value mentioned above.
4. The output air pressure should be positive 10bar for the air compressor
equipped by pumping unit, and positive 8bar should be ensured at the nozzle of
pumping unit after the conveying via channel. In case of lower than positive
8bar,case such as failure pumping or slow flow are possible due to the
insufficient vacuum.
5. Besides the two factors above should be considered firstly, pumping pipe
should be used in corresponding proper application. With feature of straight flow
channel, large steel pipe has
capacity of 1.8 liter/min, and 1.4 liter/min is available for small steel pipe. For
plastic pipe the flow channel may be bended, large pipe has capacity of
1.8liter/min, 0.8liter/min for medium pipe and 0.4 liter/min for small pipe. Oil can
be sucked out as long as the pumping pipe is 2~3cm longer than the height from
dip stick of vehicle to oil level. However, the pipe should not touch the bottom end,
or the pipe may be bended upwards, no oil can be sucked if the pipe port is
above oil level.
6. Inspection is available to check if the quick coupler is loosen after pumping
pipe had been used for a long term (procedure: air leakage can be detected by
means of blocking one end of pipe and blowing in air from the other end; oil will
not be pumped in case of air of air leakage, and foreign material should be
removed or pipe should be replaced.)
7. Findings: for Toyota camry car, the dip stick is placed above the machine
member and pumping pipe can not be inserted in; and the pipe can not be drawn
