1. How do I prime the pump?
The pump is delivered already primed
and filled with oil.
When the lines are connected, run Prime
a few times until both lines are full of oil (press and hold +
for >2s to trigger Prime)
If the oil is drawn from the
container and the pump primes itself, then go to Step 3
If the oil is not
moving in the lines when you run Prime:
By far the quickest and easiset way
to prime the line to the pump and remove any air from the pump itself is to
create a closed circuit as follows:
· Cut a piece of tubing the same
length as the line from the container to the pump
· Use this temporay tubing to
connect the output from the pump to the breather on
the container (this way the pump flows oil back into the bottle - and
· Run Prime a few times
until both lines are full of oil
· Carefully disconnect the temporary line
· Finally connect the main line
from the pump output to the nozzles.
Note: it is best not to use the
supplied breather line for this pump-priming operation - but if you do, then
you must blow all the oil out before reconnecting it!
Place a container or paper towel
under the nozzles to catch the oil coming out. Run Prime until you see
oil coming out of the nozzles, and the line contains no air bubbles longer than
must fill the oil lines downstream from the pump. Unlike a gravity feed system,
the lines will not fill themselves - the oil needs to be pumped. 1m of
oil line contains 2.54ml of oil - that can be 200km of riding before oil
reaches the chain!
2. Do I need to prime all the air out of the lines?
Air bubbles mean the PRO-OILER will run lean - when the
pump pulses, any air in the line will be pumped out of the nozzle at the same
rate as oil. If half the line is filled with air, then only half the amount of
oil required will get to the chain... [See FAQ Oil Lines]
Very small bubbles (2-3mm) may remain caught in the
pump, or at the connection tubing between the lines and the pump nozzles, and
eventually move down the line - these are harmless
The pump is designed to pump fluids, and is a poor
air-pump. When priming empty lines, bear this in mind, as you will need
to many more primes when pumping air than oil. (See
How do I prime the pump)
3. I'm running a Prime sequence, but nothing is coming out of the nozzle. What's
First of all, ensure the pump is actually running. Run
Prime with your finger on the pump - you should feel, and maybe hear
a light tapping as the pump pulses
If the lines on the intake side of the pump are empty,
then it may take several prime cycles to produce any movement - even as many as
20. Use the recommended method for filling the lines and the pump (See How
do I prime the pump)
Remember it can take a few seconds for the elasticity in
the lines to be taken up - the colder the oil, the longer the delay.
So, if you run several prime cycles there will be a
delay before oil comes out of the nozzle, and oil will continue to come out of
the nozzle until the pressure in the lines has been released.
