STOPPING

Move the ON/OFF switch by pushing the button on the side marked “0” (off).

When not working, switch the machine off and disconnect it from the power

supply.

WARNINGS AND OPERATING TIPS

After having read the safety standards carefully, apply these tips scrupulously

to obtain maximum performance from your machine. Work calmly. You will

only be able to make full use of the machine’s potential after gaining sufficient

experience. The painting conditions provided by this machine include a high

volume of air that directs the spray jet at low pressure, which provides greater

painting efficiency. In addition the stream of air shortens the drying time re-

quired for the coating material.

Grip the machine securely, put the support belt (where fitted) around your

neck and adjust it to suit your working position. The diagram in Fig. E illus-

trates the correct position.

 WARNING! During use avoid obstructing the slots in the filter cover (9

- Fig. A).

Preparing the item or surface to be coated.

The spray painting result depends on the cleanliness and evenness of the surface

before spraying. Remove all traces of rust or old paint, and sand down if neces-

sary. Fill where necessary to provide an even surface. Remove all dust from the

surface before spraying. Read the instructions on the paint tin carefully, to check

whether it is possible to apply a bonding agent before painting for better results

and in order to use less paint. Surfaces that are not to be sprayed are to be

masked using adhesive tape or newspaper.

Preparing the material to be sprayed.

Shake the tin well before opening. Generally the paint to be used must be

diluted (we suggest testing a small amount of paint before diluting the entire

tin). Follow the paint manufacturer’s indications relating to the type of diluents

and quantity to be added. If the manufacturer does not indicate how their

product is to be diluted or what diluents to use, ask your paint dealer, being

sure to indicate that it will be applied using an HVLP (high volume, low

pressure) gun. Also take the following into account. The term viscosity is

used to indicate whether a substance is very liquid or very dense. The

viscosity is low for very liquid substances and high for more dense

substances. For an estimated viscosity to be associated with paints, where

no specific information is provided on the paint tin, see the viscosity table

‘TAB 1’ below. Fill the tank (1 - Fig. G) for the gun to a maximum of ¾ of its

capacity. If necessary, add small amounts of diluents at a time after spraying

test patches on cardboard or a piece of wood.

Using the viscosity meter (13 - Fig. A)

This instrument indicates the viscosity in seconds. Mix the product and the

diluents well. Fill the viscosity meter (13 - Fig. A) with the substance to be

sprayed and count the seconds the liquid takes to flow out of the hole at the

bottom altogether (Fig. I). This period of time is the viscosity expressed in

DIN-seconds (DIN-s). Continue trying various dilutions until the correct vis-

cosity (DIN-s) for the given product is reached.

Adjusting the spray gun (Fig. G).

Fit the tank (1 - Fig. G) and close well. To choose the type of spray re-

quired (2 - Fig. H) slacken the regulating ring (3 - Fig. G) and adjust the

position of the butterfly nozzle (4 - Fig. G) in order to obtain (2 - Fig. H):

 ELECTRICAL SAFETY STANDARDS

1)

Protect yourself against electrical shocks. 

Avoid touching surfaces that

are earthed, such as hoses, radiators, etc. Do not use the machine if the

switch will not switch on or off. Get an authorised service centre to change

defective switches.

2)

Connecting to the power supply. 

The power supply voltage must corre-

spond to that indicated on the technical data plate. Do not use any other

power supply. It is advisable to fit a trip switch on the power supply line

that trips at the levels laid down in standards currently in force in the

Country in which the machine is used. Contact your local electrician. Check

that the plugs and sockets used for the power supply are compatible.

3)

Do not damage the cable. 

Never carry or move the tool by the power

supply cable and never pull the cable to disconnect it from the power

supply. To move the unit use the hand grip (3 - Fig. A) or the support belt

(5 - Fig. A where fitted). Do not pull it by the air hose (6 - Fig. A). Keep the

cable away from heat sources, oil or sharp edges.

4)

Check the power supply cable. 

The power supply cable and plug must

be checked from time to time, and each time it is used to check for any

signs of damage or ageing. If these are not found to be in good condition

the machine must not be used until it has been repaired by an authorised

assistance centre

. 

Only allow an authorised assistance centre to effect

any repairs to the electrical system.

5)

Extension cables. 

Extension cables are to have a capacity that is equal to

or greater than that required for the machine. Use the cable connection (2

- Fig. A where fitted) specifically provided for an extension cable. Prevent

the extension cable from being trodden on or crushed. Check the exten-

sion cables from time to time and replace if damaged. Do not use exten-

sion cables that show signs of wear or ageing, as they may pose a fatal

hazard. Keep them away from the working area, damp, wet, or oily sur-

faces, or surfaces with sharp edges, heat sources, and fuels.

6)

Extension cables used out in the open. 

When using the machine out-

doors, only use extension cables designed for outdoor use. Only use

extension cables that are tested and adequately marked.

7)

Warning. 

Remove the plug from the power supply socket when the ma-

chine is not in use.

 This machine has a double insulation system.

Double insulation provides greater electrical safety and makes it unnecessary

to earth the machine.

SETTING UP (FIG. C)

This machine may be supplied with some components not fitted. Remove the ma-

chine and the components supplied from the packaging and proceed to assemble

them as illustrated in the enclosed sheet.

While assembling the components the power supply plug must be discon-

nected from the power socket. Before starting the machine, check that all

assembled parts are properly secured.

FITTING THE GUN HOLDER (1) (where fitted)

When the gun holder is inserted a click must be heard.

FITTING THE AIR HOSE (2)

Complete the following steps, both on the machine casing side and the spray

gun side.

Insert the pipe coupling with the bayonet coupling (arrow a), turn (arrow b),

then pull (arrow c) to secure it properly.

FITTING THE SUPPORT BELT (3)

(where fitted)

 Never use this machine without the air filter (11 - Fig. A).

STARTING AND STOPPING

Connect the extension cable to the cable connection (where fitted) and then

connect it to the power supply plug (Fig. D). Put the spray gun into the gun

holder (8 - Fig. A). Put the machine on the shoulder strap (Fig. E where fitted)

STARTING

Remove the gun from its holder and aim it in the direction of the surface to be

coated. Move the ON/OFF switch by pushing the button on the side marked “I”

(start). A continuous jet of air will flow out of the spray gun (7 - Fig. A) once

the machine has started. Regulate the spray and flow of material (see the

‘WARNINGS AND OPERATING TIPS’ paragraph). Press the trigger (8 - Fig. G).
