OPERATION
This equipment produces a fluid stream at
extremely high pressure. Read and understand
the warnings in the Safety Precautions section
at the front of this manual before operating this
equipment.
5.1
SETUP
1. Ensure that the siphon hose and the return hose are
attached and secure.
i
If using the 2nd gun, make sure the valve is open.
(handle in line with the valve).
If not using the 2nd gun, make sure the valve is
closed (handle perpendicular to the valve).
Refer to section 4.4.
2. Fully depress the pusher stem (Fig. 18, item 4) to make sure

3. Check the engine oil level daily before starting the sprayer.
The gasoline engine oil level is determined by the engine
manufacturer. Refer to the engine manufacturer’s service
manual supplied with this sprayer.
4. Make sure the sprayer is grounded/earthed. All sprayers
are equipped with an grounding/earthing chain. Make
sure the chain reaches all the way to the ground. Check
your local electrical regulations for detailed grounding/
earthing instructions.
Proper grounding/earthing is important. The
passage of some materials through the nylon
fluid hose will build up a static electric charge,
which if discharged, could ignite solvent vapors
present and create an explosion.
5. Strain all paints with a nylon strainer to ensure trouble
free operation and freedom from frequent cleaning of the
suction filter and gun filter.
6. Make sure the spray area is well ventilated to prevent
hazardous operation with volatile solvents or exhaust
fumes.
