N77 SPRAY GUN INSTRUCTION MANUAL
Prior to operation read the instruction manual carefully

OPERATION

The spray gun has been designed as a hand held air operated tool, and in the interests of safety must only be used for the purpose for
which it has been designed. The tool should on no account be used for any other purpose for whatever reason; this could result in danger to
the operator and those within the immediate working area.
The spray gun should be connected to a clean air supply using the recommended fittings and hose size as specified in the diagram.
Whenever possible there should be an air filter and regulator in the system. The recommended pressure at the tool should measure 60psi
while running free. Check fittings and hoses regularly for signs of frying, or accidental damage. Replace any worn items before continuing to
operate the spray gun. Always connect the cup and the air hose tightly to the spray gun before use. Ensure the material and air supply are
disconnected before affecting any work on the spray gun.

ADJUSTMENT

To obtain the required spraying pattern, volume of fluid and degree of atomisation, use the Pattern Adjusting Knob, Air Adjusting Knob and
the Fluid Adjusting Knob.
a) To adjust the pattern – turn the Pattern Adjusting Set to the right to narrow the spray pattern and to the left to widen the spray
pattern.
b) To adjust the fluid output – turn the Fluid Adjusting Knob to the right to reduce the fluid output and to the left to increase the
fluid output. Turning the Fluid Adjusting Set fully to the right will stop the fluid completely; the spray gun will then only emit air.
c) To adjust the air volume – turn the Air Adjusting Set to the right to reduce the air volume and to the left to increase the air
volume.
d) The recommended air pressure is 3.0 – 3.5 bar (43 – 50 psi) the installation of a spray gun regulator like the 2SPRAY DR5 can
insure that correct air pressure is kept at all times. Recommended sprays distance to object is 20 – 25cm (8 – 10 inches).

SERVICING

a) Clean air cap, fluid nozzle and fluid needle with a brush after each operation.
b) Flush the gun material passage with a compatible solvent.
c) Do not submerge complete spray gun in solvents.
d) Fluid needle packing should not be tightened completely, or the fluid needle set will be sluggish.
e) Turning the fluid adjusting knob too far to the left will weaken the fluid needle spring; this will make the fluid nozzle leak.
f) Before installing or dismantling the nozzle, the fluid knob assembly must be dismantled and the trigger pressed back to ensure
that the nozzle and needle disconnect, otherwise wear and tear can be caused on the needle and nozzle causing a bad seal.

PERSONAL PROTECTIVE EQUIPMENT

The use of breathing mask is recommended at all times when spraying. The noise level may exceed 85dB (A) when the spray gun is being
used, a sound absorber protection is also recommended. Always wear goggles and gloves when spraying or cleaning. No vibrations are
transmitted to the operator when using the spray gun.

SAFETY

•
Never allow untrained or unauthorised persons to operate this spray gun.
•
Never exceed the recommended air pressure.
•
Never use matches, smoke or operate a spray gun in the vicinity of a naked flame.
•
Never aim a spray gun at people
•
Never spray food or chemicals through spray gun
•
Do not carry or pull the spray gun by the hose, this could cause failure of the hose/ spray gun connection resulting in danger to the
operator or other workers.
•
Use only original spare parts.
•
Do not use the following solvents. 1,1,1-Trichloroethane and Methylene Chloride. These solvents can chemically react with
aluminium in spray guns and fluid caps possibly causing an explosion.
•
Do not use these solvents for equipment cleaning or flushing. Spray gun should never be stored in acid laden cleaners. If in doubt
consult material supplier.
