4. MAINTENANCE
Make sure that the machine is not live
when carrying out maintenance work on
the motor.
This machine has been designed to operate over
a long period of time with a minimum of
maintenance. Continuous satisfactory operation
depends upon proper machine care and regular
cleaning.
Troubleshooting
1. Motor hums but does not spray or irregular
spraying
• Worn swirl head.
• Replace swirl head.
• Pick up pipe not in the right position.
• Re-adjust pick up pipe.
• Blocked pick up pipe.
• Clean with thinner.
• Blocked nozzle.
• Clean nozzle.
• Blocked filter.
• Clean with thinner.
• Control knob needs adjustment.
• Adjust.
2. Atomization is not good
• Volume adjustment is not correct.
• Adjust.
• Paint too thick.
• Check viscosity of the paint.
3. Over painting
• Spray gun not clean, or not lubricated,
resulting in piston being stuck in cylinder.
• Disassemble spray gun and clean with
thinner.
• Too much paint.
• Adjust the volume clockwise to reduce
spraying. Two thin coats are better then one
thick coat.
• Viscosity too low.
• Check viscosity.
4. Motor louder than normal
• Spray gun not clean, or not lubricated,
resulting in piston being stuck in cylinder.
• Disassemble spray gun and clean with
thinner.
5. No spray, no sound
• No electricity.
• Check power supply.
6. Operating sound not right
• Poor output adjustment.
• Re-adjust.
• Not enough paint in the container resulting in
air being sucked in.
• Refill with paint.
• Not diluting properly or not passing pick up
pipe completely.
• Check pick up pipe and viscosity level.
7. “Orange Skin” excessive fogging
• Incorrect solvent is used.
• Use correct solvent.
• Spray gun too far from the surface.
• Hold spray gun closer to the object.
• Paint too thick.
• Thin the paint.
Cleaning and maintenance
Fig. G
Always remember to disconnect from
the mains supply before cleaning the
spray gun or paint container.
It is essential that the spray gun is cleaned
thoroughly after every use. Failure to clean it will
almost certainly result in blockages and it may not
operate when you next come to use it! The
guarantee does not cover cleaning a sprayer that
has not been properly cleaned by the user. The
following action must be taken after every use:
• Empty any remaining material from the
container.
• Clean the container thoroughly with the thinner
thatwas used.
• Pour some thinner into the container and
spray through the spray gun until only clean
thinner is coming out of the nozzle.
• Thoroughly clean the paint pick up pipe and
filter with thinner.
• Clean the basket and nozzle and remove any
other debris or paint that remains.
• Turn the spray gun upside down and apply a
few drops of light oil to the two apertures (F).
This will lubricate the piston and cylinder.
If your spray gun should require extra internal
cleaning, it may be necessary to disassemble it. If
so the following action should be taken:
• Remove the plug from the mains socket.
