•A 5 kilogram gas bottle will provide a minimum of 6000 shots of a 15 ml
dose.
•LPG is not compatible with standard air hoses and fittings. LPG will corrode
them.
•Normal pressure range 40-80 psi.
•Care should always be taken working with LPG. Keep LPG bottles upright,
avoid leaks, avoid working in enclosed areas or near open flames. Avoid
smoking.

Disassembling the Power Doser™

Page 5of 14
Step 1 Make sure trigger is in correctly. (Refer to page 6 for replacement instructions.)
Step 2 Place piston rod through handle and reseat piston rod O-ring and U-cup making
sure the U-cup face is towards the barrel end. Then reseat backing washer (for
the 2 ml, 10 ml and 30 ml gun) or another piston rod O-ring (for 60 ml gun).
Step 3 Seat inlet O-ring on piston rod and place main spring on.
Step 4 Place inlet ball and inlet spring into inlet fitting and quickly tip and screw onto end
of piston rod, do not over tighten! Screw adjustment nut on.
Step 5 Reseat barrel O-ring, lubricate barrel and plunger O-ring with Genesis Power Lube
or petroleum jelly and screw barrel into handle.
Step 6 Place outlet rubber gasket onto back of nozzle, place nozzle through barrel cap.
Step 7 Seat outlet check onto outlet spring and place in front end of barrel.
Step 8 Screw on barrel cap.
NOTE:
Do not over tighten inlet nozzle onto piston rod.
REMEMBER:
Lubricate barrel, plunger O-ring and piston rod with Genesis Power Lube or petroleum
jelly.

Cleaning the Power Doser™
After use, follow these steps.
Step 1 Pump out product at the end of each day after use.
Step 2 Pump through good quality mineral oil, then pump out.
Step 3 Unscrew barrel & wipe out with a clean rag.
Step 4 Lubricate Plunger “O” ring with Genesis Power Lube (or petroleum jelly).
Your applicator is ready for the next job.
Maintenance
Cleaning the Power Doser™regularly will prevent it from getting
‘clogged up’ and failing while in the middle of a task.
*Only clean the Power Doser™with warm soapy water when
disassembling the applicator for maintenance.
Lubricating the Power Doser™
Lubricating the Power Doser™regularly with Genesis Power Lube
(or petroleum jelly) will help prevent wear and tear and will assist refill.
First, unscrew the barrel and liberally apply Genesis Power Lube (or
petroleum jelly) to the Plunger “O-ring”and inside the barrel.
It is best to lubricate the Power Doser™ every day or when the return of the piston
rod begins to slow.
WHEN LUBRICATING THE POWER DOSER™, ONLY USE LUBRICANTS SUGGESTED IN
THIS MANUAL.

Troubleshooting
A Problems and Solutions for the Power Doser™
Problem
Solution
i. Trigger leaks air/gas.
a) Trigger may be dirty, therefore remove trigger and clean trigger and
chamber (see instructions).
b) Trigger has failed, replace with spare in spare parts kit.
c) The trigger cavity (chamber) is too small in the handle therefore
return gun to factory to burr out. A very tight fit indicates this
problem.
ii. Air/Gas leaks at barrel.
a) Usually barrel has been over tightened and is now cross threaded,
temporary solution is plumbing tape around thread of barrel.
b) Check if the barrel O-ring is missing or has skewed.
iii. Barrel blows off and
dispensing action too fast.
a) Usually indicates operator is not using a regulator. Barrel thread will
probably be ruined. Obtain regulator and new barrel.
iv. Gun is stuck and will not
completely refill.
a) The gun may have been lubricated with oil that is not suggested in
this manual. Using the incorrect lubricating oil will break down and
gum up the entire mechanism. Take apart following disassembling
instructions, wash in soapy water removing all oil sediment. Rebuild
Power Doser™following re-assembling instructions and lubricate
with Genesis Power Lube or petroleum jelly. “Oiling” guns is
commonly accepted as good practice therefore, this can be a
problem for the Genesis Power Doser™. Often when a gun will not
work disassembling it, washing it, lubricating it and then rebuilding it
will fix the problem.
v. Leaks fluid at back and will not
refill.
a) Broken piston rod, replace.
vi. When converted to a 10 ml
Power Doser™, the plunger
will not travel all the way to
the end.
a) Increase pressure, as the 10 ml Power Doser™requires more
pressure to operate.

B. Usage Problems
The vast majority of problems relate to usage with a particular product and not the Power Doser™
itself. Is the product “thick”or “thin”, “oily” or “watery”, “harsh” or “kind”? Quite often the
solution will relate to the suction hose.
Problem
Solution
i. The piston rod will not return
fully or quickly enough.
a) Has the gun been lubricated with oil? Re-lubricate plunger O-ring
with Genesis Power Lube or petroleum jelly. See v) in section A
(pg. 8).
b) Is it the correct suction hose for that chemical? See section C
(pg. 10).
c) Elevate drum for gravity assistance, eg, place on 44 gallon drum.
d) Possibly main spring worn, stretch one centimeter and/or insert a
spacer.
e) Suction hose may have restriction, eg, small diameter draw off
system to large hose or a sieve was inserted that is restrictive.
f) Is there an air/gas leak impeding return of piston rod? If it is, stop
leak by cleaning trigger, or replace it.
g) Has the piston rod head swollen from a particular chemical and
jammed in the barrel? Take plunger O-ring off to test. If jamming,
obtain replacement piston rod.
ii. The piston rod returns but air
is in the barrel.
a) Front valve not seating properly. Screw off nozzle and clear any
obstructions. Check if outlet check is worn or shrunken from
chemical, replace from spare parts kit if necessary.
b) Check where suction hose fits on inlet nozzle, may be worn and lets
air in. Cut off one centimeter of hose and refit (avoid using a clamp
or wire because of the shape of the nozzle).
c) Check suction hose to chemical, ensure no air is getting in.
iii. The guns “spits”.
The refill is too quick. Often the operator sees this when testing with
water and the problem disappears when a chemical is used. For thin
chemicals do one of the following:
a) Check if outlet check and spring are worn. Replace if necessary.
b) Insert an inlet nozzle reducer to slow the refill.
c) Double up front valve spring with spare from spare parts kit.
d) Use thin suction hose or tie suction hose to slow the flow.
e) Ensure chemical drum is lower than the level of the application
surface.

iv. The gun leaks out the nozzle.
a) Check front valve, both the spring and outlet check. The check may
not seat, replace with spare. The spring may be too weak therefore
stretch or replace.
b) Chemical drum elevated so high that gravitational pressure is
excessive and keeps valves open.
c) Sometimes the leak is because of the nozzle, ie, it runs out of the
nozzle outlet between it and the valve, just keep nozzle horizontal
to ground while operating.
v. No ‘Draw-off system’.
a) The gun is used for many purposes and a universal ‘draw off
system’ hasn’t been devised. Genesis draw off systems are
available for several products, please phone toll free +44 (0) 800
214 811 for more information. In the meantime, cut a hole in a
spare drum cap and push hose to the bottom.
vi. The gun will not ‘Suck up’.
a) Test front valve –it may be a seating problem. To test –remove
nozzle and valve, depress trigger and when plunger is to front hold
finger over barrel outlet hole then release trigger –if it fills then
that is the problem. Check for obstruction and if necessary, replace
outlet check and/or spring.
b) Check suction hose to inlet nozzle connection –cut off one-
centimeter hose and refit.
c) Check inlet valve –if necessary, replace or clear obstruction.
C Suction Hoses
Most Power Dosers™have been sold for a single purpose, either pursuant to a company
promotion or purchased by a customer for a single job. The Power Doser™ will therefore work
adequately for that job but then fails when used for something else. The solution to the failure is
then related to specific product knowledge. As a general rule, the Power Doser™ works with
“everything” but changes may be required to suction hoses and to the gun by tweaking it, eg,
with a spacer for a high viscosity product or inserting a weaker main spring for a low viscosity
product.
Some general principles are:
a) Thick products require a large suction hose and maybe a spacer.
b) A thick and harsh product may require a large EVA suction hose and spacer.
c) Thin products may work best with the 6 mm suction hose and/or inlet nozzle reducer.
