3. AIR SUPPLY

WARNING! Ensure the air supply does not exceed 125psi

while operating the unit. Too high an air pressure will shorten

the life of the unit due to excessive wear and may cause

damage and/or personal injury.

3.1 Ensure the blaster air valve (trigger) is in the ‘Off’ position

before connecting to the air supply.

3.2 Keep the air hose between the compressor and the unit a

reasonable length and install an air filter and water separator

(fig.1).

3.3 Drain the air tank daily. Water in the air line will damage the

unit.

3.4 The recommended hook-up procedure is shown in fig.1.

3.5 The minimum hose diameter should be 1/4" I.D. and fittings

must have the same inside dimensions.

3.6 Use correct hoses and fittings.

3.7 Keep hoses away from heat, oil and sharp edges. Check

hoses for wear and ensure that all connections are

secure.

safety instructions in Section 1 before use.

WARNING! Wear approved ear, eye, hand and respiratory

protection when operating the blaster.

WARNING! Ensure the air supply does not exceed 125psi

while operating the unit.

5.1 Control valves.

5.1.1 Air Supply Valve See fig.3G. This valve controls the flow of air

coming into the unit from a compressor or workshop air supply.

When this valve is opened the incoming pressure of air will

5.1.2 Gun Supply Valve See fig.3C. This valve controls the flow of air

to the sand pick up point at the base of the unit and on to the

blasting gun.

5.1.3 Sand Metering Valve See fig.4Q. This valve controls the

amount of sand flowing down from the tank.

5.1.4 Blasting Gun See fig.5W. This valve opens the flow of sand

from the blasting nozzle and should be either open or shut.

5.2 Abrasives.

There are two types of abrasive grit:

5.2.1 Expendable - Use once and dispose of, recommended for

large surfaces - Copper Slag and Olivene (silica-free sand).

We recommend Sealey Blasting Grit, part number B/25KG

(Use with the 5mm nozzle).

5.2.2 Re-usable - more expensive and recommended for cabinets -

Glass Beads and Fused Alumina.

5.3 Filling the tank with abrasive.

5.3.1 Close the Sand Metering Valve See fig.4Q. Valve lever should

be at right angles to the fitting

WARNING! If an air line is connected ensure the tank is

depressurised by turning off the air supply and operating

the blasting gun until the pressure gauge registers zero.

5.3.2 Undo the tank cap using the attached lever. See fig.3L.

5.3.3 Insert a funnel into the opening.

5.3.4 Fill the tank up to 3/4 full only.

5.3.5 Refit the tank cap ensuring that the 'O' ring seal is in place and

4. ASSEMBLY

WARNING! Before operating the unit ensure you read,

understand and apply Section 1 Safety Instructions.

4.1 Assembling the handles and wheels.

4.1.1. Place a protective layer on the floor such as cardboard or cloth

and lay the tank down with the water trap and gauge upwards.

Place blocks either side of the tank to prevent it rolling.

4.1.2. There is a specific left hand and a specific right hand handle

as the mounting holes in them are at different angles. When

correctly fitted the two handles should be parallel.

Referring to fig.3, loosely attach the two handles (A) onto the

fixing brackets (B, D, F & H) using the nuts, bolts and

washers provided. Do not tighten yet.

4.1.3 Referring to fig.4, slide the axle (P) through the holes at the

bottom of each handle so that it protrudes equally either side.

Slide a wheel (M) onto each end of the axle followed by a

washer (O). Fix each wheel by sliding a split pin (N) through

the holes in the end of the axle and retain the assembly by

bending over the pins.

4.1.4 Now tighten the nuts and bolts at the four handle mounting

positions. (B, D, F & H in fig.3).

4.2 Assembling the front foot.

4.2.1 Now lay the tank down on its handles and referring to fig.4, fit

the front foot (T) to the spigot welded onto the tank and retain

the assembly by putting the split pin (V) through the foot and

spigot and bending it over.

4.3 Attaching the blasting hose.

4.3.1 Referring to fig.4, take the open end of the blasting hose (R)

and slide the wire screw clamp (S) over the end of it. Now

push the hose fully onto the sand outlet fitting below the sand

metering valve and tighten the wire screw clamp to retain it.

4.4 Fixing / changing the blasting nozzle.

4.4.1 Referring to fig.5, depress and hold the blasting gun handle

(W) to release the seal on the nozzle. Unscrew and remove

the knurled nozzle holder (Z) and release the handle (W).

Push the nozzle (Y) and the 'O' ring (X) out of the holder.

Insert the required nozzle into the back of the holder (Z)

followed by the 'O' ring (X). Depress the blasting gun handle

and screw the knurled nozzle holder back into place.

6. OPERATION 7. MAINTENANCE

WARNING! Wear approved ear, eye, hand and respiratory

protection when operating the blaster.

6.1 Close all valves before connecting the air.

6.1.1 Connect the air supply as described in Section 3 to the air inlet

fitting. See fig.3J.

6.1.2 Set the incoming air pressure. Do not exceed 125psi.

6.1.3 Open the Air Supply Valve (See fig.3G) and allow the tank to

pressurise.

6.1.4 Open the Sand Metering Valve. See fig.4Q. Valve lever should

in line with the fitting.

6.1.5 Open the Gun Supply Valve. See fig.3C.

6.2 The unit is now ready for use.

6.2.1 Fully depress the Blasting Gun lever to commence blasting.

6.2.2 Before blasting unfamiliar material, spot test to ensure that

damage/pitting will not occur to the material.

6.2.3 Use even passes of the blaster to remove material such as

rust, body filler or other soft materials. Do not blast in any one

area for more than a few seconds at a time.

6.3 The unit is supplied with 5 ceramic nozzles. See fig .5. Select

the appropriate nozzle for the task.

6.3.1. To change the nozzle refer to section 4.4

WARNING! DO NOT use the sand blaster without a nozzle

fitted.

WARNING! Disconnect from the air supply before

performing any maintenance!

WARNING! Regularly check for wear in those components

that carry the air/abrasive mixture, in particular the blast

hose.

7.1 Blast Hose - To inspect the blast hose and associated fittings

first close the Sand Metering Valve, see fig.4Q. Wearing your

protective clothing, operate the blasting gun until only air is

passing through it. Close your hand lightly around the hose and

slide it along the full length with the blasting gun closed. You

should be able to feel any air leaks from the hose and

associated fittings. Also, where the internal wall of the hose has

worn thin the hose will begin to blister. If any blisters or leaks

from the hose are discovered the hose can no longer be used

and must be replaced immediately.

7.2 Blast Nozzles - Check for wear and replace as necessary.

7.3 Sand Outlet Fitting - The sand outlet fitting to which the blast

hose is connected should also be periodically inspected for

wear.

WARNING! The following items should also be checked

on a regular basis.

7.4 Hoses & Clips - Replace immediately at any sign of damage.

7.5 Filler Cap Gasket - Check to ensure it provides an airtight

seal.

7.6 Water Separator - Drain before use by loosening drain screw

while separator is pressurised.
