4.5 Adjusting of the wax products
Never close the handwheel regulator of the air ( nr. 19 ), otherwise it could daub the gun.
Clean the residual wax in the extension operating only the first time of the lever.
Standard adjustment:
- Working pressure 4 bars .
- Open the air by turning of at least half a turn the handwheel regulator of the air ( nr. 19 ) and adjusting the product’s flow by the handwheel regulator ( nr. 9 ) .
- The total air regulator ( nr. 23 ) has to be completely open.
- Assembly the extension for the work that you have to do.
5- MACHINE DESCRIPTION
5.1 Allowed used:
5.1.1 Spraying of liquid, bituminous and stone protection products, waxes for encased parts, protective and insulating products contained in special tins or
loose.
5.1.2 Always operate the spray gun in environments that are suitable for the type of the products being used.
5.1.3 Usecartridges having the following characteristics.The product must be specifically suited for spraying.
5.2 Forbidden uses:
5.2.1 The use of any other products different from those listed above is not allowed.
Based on the safety sheet of the product being sprayed, verify that it is in fact compatible with the operating equipment (spray booths, filters, etc..)
and that the individual safety devices are suitable for the operator and for the handled product.
6- NOISE LEVEL
The equivalent continuous level of acoustic pressure calculated in scale A, measured at a horizontal distance of 50cm. With bituminous products is <80 dBA
during spraying
.
7- USING THE EQUIPMENT
7.1. Supply, see point 4.2.
7.2 Pneumatic connection of air supply, see point 4.1
7.3. Press the trigger and point the spray gun towards the object being treated at a variable distance of 10 to 30 cm.
7.4. At the end of operation, disconnect the air supply and hang the spray gun on the special hook
8- STANDARD ADJUSTMENT
Turn hadwheel n.2 (Pic.B) clockwise in such a
way as to close the air passage gradually, thus
reducing pulverisation (rougher)
Turno hadwheel n.2 (Pic.B) anti-clockwise in
such a way as to open the air passage gradually,
thus increasing pulverisation (smoother)
8.4 Combined adjustment:
8.1 Adjusting product pulverisation:
8.2 Adjusting product quantity:
Turn handwheel n.3 (Pic.A) clockwise so as
to gradually reduce rate of product flow.Turn
anti-clockwise to increase rate of product flow.
8.3 Adjusting total air flow input:
This is carried out by flow adjuster n.4 (Pic.A).
Turn anti-clockwise to increase air flow (higher
input).Contrarily, turn clockwise to decrease
air flow until the flow is totally shut off
.
Combined adjustment of handwheels (n. 2 and 3) and of the flow adjuster ( n.4 ) in order to obtain smooth or rough surfaces according to requirements and to
obtain a finish of the treated part as it was originally.
9- SPECIFIC ADJUSTMENT OF THE GUN EQUIPPED WITH PRESSURE REDUCING VALVE WB (pic.B)
This gun is equipped with a special pressure reducing valve so that some specific water based products can be used.
PREMISE:Contrary to solvent based materials, it is necessary with certain water-based products which tend to block the gun, especially when adjusting rough
sprays, to operate contrarily, as in the following instructions:
9.1 Adjust the handwheel n.3 ( pic.A) of the material by turning it clockwise to a maximum of 10-12 mm,so as to allow the maximum opening of the meedle
and thus obtaining a maximum flow out of material. Leave the adjustment in this way to obtain smooth or rough surfaces and proceed as follows:
9.2 The pressure reducing valve ( WB on pic.B) is to be adjusted according to the operator’s requiremnts.
9.2.1 Adjustment fro smooth surfaces: Fully turn the ring nut clockwise and during use, air will flow out of the tank (by decreasing the pressure in it) thus
decreasing the flow of material. Now pulverisation can be adjusted by fully opening the handwheel.
9.2.2 Adjustment for rough surfaces: To increase rate of product flow, partially close the ring nut (never fully close) by turning anti-clockwise, thus increasing
the pressure inside the tank and increasing material flow.Now adjust pulverisation using the handwheel n.2 ( pic.B ) that in this case must be partially
closed(depending on the surfaces) Never fully close.
9.3
Combined adjustment
Combined adjustment of handwheels (n. 2 / 3 and WB), in order to obtain smooth or rough surfaces according to requirements and to obtain a finish of the
reated part as it was originally.
