Paint Spraying Hints
PAINT THINNING
For a professional looking finish paint must be thinned. If manufacturers recom-
mendations on thinning are not available, the following can be used as a
general guide.
Water based paints (emulsions) ................... 10-20% water.
Oil based paints (gloss) ................................. up to 10% thinners.
Cellulose paints .............................................. up to 50 % cellulose thinners.
HANDLING THE GUN
the first requirement for a good resultant finish is the proper handling of the gun.
The gun should be perpendicular to the surface being covered and moved par-
allel with it. The stroke should be started before the trigger is pulled and likewise ,
released before the stroke is ended. This gives accurate control of the gun and
material.
The distance between the gun and the surface to be covered should be 6 to 12
inches depending on the material and atomising pressure. The material depos-
ited should always be even and wet. Lap each stroke over the preceding stroke
to obtain a uniform finish.
NOTE: To reduce overspray and obtain maximum efficiency, always spray with
the lowest possible atomising air pressure.

Drain Valve
After a period of use, especially if the weather has been warm and humid, it is quite possible
that water (condensate), will have accumulated in the receiver.
To remove this condensate, first switch OFF the Bronco after ensuring that there is at least
some compressed air in the receiver.
Hold the whole machine securely and raise one end so that the drain valve assumes the
lowest position. Now simply loosen the drain valve for a few moments allowing the air and
any water to escape.
Re-tighten the drain valve and return the Bronco
to its normal position.
Thermal Overload
Should the machine overheat, the thermal
overload will intervene. Wait for at least 5 minutes
before pressing the reset button, indicated in the
illustration opposite.
NOTE: The reset will not operate until the machine
has cooled sufficently
Maintenance
It is important to keep the Bronco Air Compressor clean, this can be carried out using a
small soft brush and a vacuum cleaner.
In particular the air filter should be inspected periodically, so that it is always kept clean. If
this instruction is not adhered to, a loss of performance could occur, even worse, any dirt
passing through the filter could make its way into the cylinder head and adversely affect
the valves. This could lead to more extensive damage necessitating its dismantling and
replacement parts etc.
Before carrying out any service work, ALWAYS disconnect the Bronco from the mains supply. If
necessary allow the machine to cool down first. When ready to start, proceed as follows:-
1.
Release any air remaining in the tank by loosening the drain valve slightly.
2.
Remove the six cover retaining screws, and lift off the cover to reveal the pump and motor.
3.
Clean the air intake filter, to do this :-
a)
Carefully prise off the plastic end cover and remove the sponge element from inside.
b)
Clean the inner housing, using a soft brush.
c)
The sponge may be gently washed in warm soapy water, rinsed and allowed to
dry thoroughly before refitting.
d)
Refit the plastic end cover, ensuring it is clipped back into its original position.
e)
Carefully refit main cover and secure in place using the six screws removed previously.
Note : If any part of the filter is damaged, you should obtain replacement parts from your
CLARKE dealer.
Caution
Do not attempt any repairs or adjustments if you are uncertain as how it should be
done. If you have any queries, please contact your nearest CLARKE dealer, or
otherwise telephone CLARKE International, Service Department, on: 020 8988 7400).
