Assembly
•Do not use the machine unless completely assembled.
Electrical equipment
•Your machine does not need to be grounded. If your machine is equipped with three pin power plug, you
must use three pin/hole wall outlet as well. Never remove the ground pin.
•Observe all basic safety rules when using electrical equipment to prevent risk of fire, injuries by electrical
shock and other hazards. Before using this device, read this manual entirely and follow all safety instructi-
ons. Before using this device, read this manual entirely and follow all safety instructions.
•Make sure the power cable plug is plugged into the correct wall outlet. The voltage on the specification
label must be the same as the voltage in the wall outlet. Higer voltage may damage the engine and too
low voltage will not provide the machine with sufficient power.
•Before connecting the machine to the wall outet make sure that the main switch is in the "OFF" position.
When you finished your work, disconnect the power plug from the wall outlet and switch off the main switch.
•Do not use the machine if it cannot be switched on or off by using its main switch. Any machine or device
with such defect is dangerous and must be repaired immediately.
•Never carry electrical tools and appliances by their power cord. When disconnecting the plug from the
wall outlet, never pull the cable by its cord.
•Protect the power cable from high temperatures, oils, paint thinners and make sure that the cable is not
hanging over sharp edges.
•Inspect the power cable regularly. If damaged have it replaced by qualified technician. Inspect extension
cables regularly. If damaged, have it replaced.
•If you need to use an extension cable, use cable with appropriate power rating. Use only completely
unwound. Inspect cables for damages regularly. Damaged cable must be repaired or changed immediately.
•Before performing any maintenance, repair or adjustment, switch off the main switch and disconnect the
power cable from the wall outlet.
•Make sure no one may incidentally swith your machine on. Do not keep your fingers close to the main
switch, unless absolutely necessary.
•Do not use in environments where explosives are stored or used (paintshops, warehouse with flammables etc.)
•Do not use in humid environments or if wet.
•Do not use your machine in rain.
•Keep your machine away from flammables. Do not use close to flammables or explosives. Using your
machine close to these dangerous materials may cause severe injuries or death to the operating personnel.
•Do not touch grounded surfaces such as pipes, heaters, stoves and refrigerators. There is a higher risk of
electrical injury if you body is grounded.
Compressed air
•The supplied air must be dry and compressed according to the required specifications. The air flow
supply must be sufficient. Higher supply pressure decreases the life expectancy of the machine and
increases the possibility of injuries.
•The coupling that connects the machine with the supply apparatus must have the prescribed dimensions.
•Take extra caution if using the machine near water. Water may seriously damage your tools or machine.
Do not forget to drain the condensed water from the pressure container. Also completely dry out the air
supply hose.
•Make sure no dirt can enter the inside of the machine. Keep inlet and outlet openings clean.

6
•Before uncoupling compressed air piping or hose, turn off the air pressure supply. Wait until the pressure
equalizes.
•Before starting your work, inspect all couplings and piping for leakage. If leak is found repair it immediately.
Leakage puts an extra strength on the compressor and increases the operational cost.
•Inspect the pressure hoses and piping system regularly. If you discover a leakage during work, stop
working immediately. Have the defective part repaired or changed for a new one. Pressure hoses may
not be twisted. Observe the line on the hose surface. Hoses marked like that must be kept as straight as
possible.
•Do not run the pressure hoses over sharp edges or through places where they may be damaged or cut.
•Before installing a new hose blow compressed air through it first.
•When you have to run the hose through a various structures, use protective bushing and inspect them regularly.
•Use protective plugs and covers to prevent dirt form entering the machine.
Power equipment
•Before performing any maintenance on hydraulic equipment, turn of the air supply and make sure to lower
the air pressure slowly. Let the pressure equalize.
•If your machine is equipped with pressurised springs, use suitable device to release them slowly.
•Before throwing the packaging material out, make sure no part is left inside. If so, take it out and install it.
Use the part listing for check-up and the installation drawing for guidance.

•Push the end of the vacuum hose with the coupling into the container. Using hose coupling screw the brush
head assembly on the other end of the hose. Connect one end of the abrasive substance supply hose
(with the coupling) to the air supply. Connect the other end of the hose with the coupling to the abrasive
substance outlet pipe.
Note: The ideal operation pressure is 793 kPa. DO NOT USE pressure higher than 965 kPa.
•Your machine is now assembled and ready for use.
Operational instructions
•Use protective helmet, respirator, protective gloves and protective working clothing.
•Set the air pressure on the air supply compressor to 793 kPa. (You may set different pressure - higher or
lower, based on the surface you will be cleaning).
•Connect the air supply hose coupling to the inlet on the pistol handle.
•Connect the power cable to the wall outlet.
•Aim the pistol at the surface to be cleaned and turn on the switch on the vacuum head.
•Hold the pistol with one hand and with your other hand hold the brush handle.
Note: Do not place the brush on the cleaned surface! The brush only protects the abrasive substance from
spraying away and keeps the vacuuming cycle closed so the abrasive substance may be recycled.
The brush IS NOT designed to help you clean the surface.
•Move both hands in the required direction to clean the rust from the surface before performing the final
finish.
To change the size of the blasting beam turn the nuzzle adjusting nut to extend or shorten
the length of the nozzle.
•The brush has been designed for straight surfaces, edges or corners.
•Before starting your work spread the hair of the brush so it will not cover the blasting beam. (The abrasive
substance will wear out the brush hair eventually).
•If you blasting an automobile door for example, we recommend to place the brush hair around the edges to
increase the vacuum and coverage. It is also safer and the surface quality is better.
•After finishing your work lift the vacuum head and take dust out of the filter.
•After about 1 hour of work, lift the vacuum head up and blow the dust away.
•When blasting right angle corner aim the pistol at 45 degree angle to reach the most inner part of the fold.
Use slow circular motion during blasting to achieve best results.
•When you finish your work release the two clamps, empty the dust reservoir and store the machine in safe
and dry place.
