Please read the following instructions fully and carefully before use. Our spray guns are mainly designed to use cleaning solvents like Trichloroethane 1.1.1. Please check the availability of suitable chemical that would be required to clean the stain you commonly need to. Our spray guns are capable of delivering the solvent spray in high pressure and velocity, and as such, necessary precautions have to be followed during handling of the spray gun.


  • Make sure to check the voltage rating marked on the spray gun box pack, and ensure it is compatible with the voltage rating in the area where you wish to use it. For example, if the voltage rating marked on the spray gun box is 220V AC, 50/60Hz, then it is important to note that the unit is ONLY suitable only in areas where the supplied voltage rating is of 220V AC.
  • Do not use the unit in a closed room. Ensure the usage area of the spray gun is well ventilated.
  • It is VERY important to note that the Spray Gun is NOT to be used in presence of other equipments with open flames or sparks. Also, It is essential that the spray gun is only used in a strictly NO SMOKING area.
  • Do not leave the spray gun unit tilted, when not in use. The spray gun must be kept on a flat surface or hung on a spring tension when it is not used.


  • Plug in the unit into a suitable power socket.
  • Remove the solvent jar from the spray gun, ensure the jar is clean and free from any dirt, and then fill the required solvent in it. Close the solvent jar back tightly to prevent any kind of spilling / leaking of the solvent from the unit.

  • In the case of TS11 and TS16 models of spray guns, please remove the protective plastic cap from the straight nozzle by pulling it out, before using the spray gun. If you switch on the unit without removing this plastic protective cap form the nozzle, you will surely cause serious damage to the spray gun and/or the user. Also, ensure to plug the cap back on the nozzle once you have finished the work with the spray gun.
  • While cleaning of the garments / fabrics, try to sort out the fabrics into thick or closely woven, medium woven, light or loose woven. As the pressure needs to be adjusted individually to suit different types of fabrics. For cleaning any other articles, please select the spray pressure as needed. Wrong pressure setting can damage the fabric or cause inefficient cleaning.
  • Turning the pressure control knob at the rear of the spray gun in a clockwise direction reduces the pressure of solvent coming out of the spray gun. Please do not close it fully, since it may completely stop the solvent from coming out of the spray gun.
  • DO NOT POINT THE SPRAY GUN AT ANY PERSON OR ANIMAL, before or after switching the unit on. It can cause serious non-reversible injuries.
  • The spray pressure can be checked in the open air before actually using it on any item, to identify the ideal pressure that would be required. The spray could be adjusted as required and then used for the cleaning purpose.
  • Ensure that the unit is kept upright while on use, point the nozzle onto the article which needs cleaning, and then activate the spray gun by pressing the trigger switch. To stop the spray, just release your finger from the switch.
  • Ensure that the unit is kept upright while on use, point the nozzle onto the article which needs cleaning, and then activate the spray gun by pressing the trigger switch. To stop the spray, just release your finger from the switch.
  • It may take just a few seconds after you press the switch, that the solvent in the jar of the spray gun starts getting sprayed out.
  • You may experience slight vibration and sound when the unit is activated.
  • If the spray gun does not spray out the solvent, turn the pressure-control knob located at the rear of the spray gun anticlockwise, until sufficient solvent is getting sprayed. Turning the knob anticlockwise will increases the pressure and is more suitable for thick fabrics, while turning the pressure control knob in a clockwise direction, reduces the pressure, and is more suitable for lighter or thinner fabrics.
  • If the unit is fitted with the adjustable nozzle (as in Wonder TS11A and Wonder TS16A), the spray pressure and spread area can be further controlled and adjusted by turning the adjustment knob located on the nozzle. You can achieve a fine mist spray, and also a piercing straight line spray, by turning this adjustment knob on the nozzle.
  • Maintain a safe distance of 5-40 centimeters between the nozzle and the fabric / item depending on the type and thickness of the fabric, nature of item, type of spot / stain, and ensure that correct pressure is adjusted.
  • Remove the dirt stain / clean the item by spraying the solvent in a circular motion moving from outside of the stain / dirt patch to the inside side or centre of the stain.
  • Once the stain has been removed and cleaned, release your finger from the trigger switch to switch off the spray gun.


  • Do not drop the unit, since it could get severely damaged. Should the unit get dropped by mistake, please thoroughly check the unit including the electrical connections for any loose contacts before further usage. If the spray gun is found to be damaged at any point, please do not use it. It must be immediately sent for repair at the nearest service centre. Before you remove the wire from the power socket, ensure that you switch off the power to the socket.
  • Do not use the unit continuously or non-stop. A rest time (15 seconds on and 15 seconds off) for the unit is recommended at regular intervals to increase the working life of the spray gun. Do not use the unit with the nozzle pointing upwards..
  • Do not use the unit for spraying only water as this may cause some of the parts to wear out more faster.
  • Do not clean the unit with any type of flammable solvents / chemicals.
  • Do not use or spray any solvent/chemical, if the hazard associated with it is not known. Consult with the solvent manufacturer or dealer before use of the solvent.


  • Ensure that the unit is not connected to the power socket while you are trying out any adjustment, servicing or maintenance on the unit.
  • Ensure that the electric wire of the unit is properly secured so as to avoid any damage due to abrasion on the wire.
  • After usage of the unit for the day, open the solvent jar and empty out the solvent completely. Spray out the remaining solvent from the spray gun as well.
  • In model TS11 and TS11A lubricate the unit through the oil hole located at the top of the unit near the adjusting roller. Do not use more than 2-3 drops of oil. Regular machine oil can be used.
  • Fuse Replacement: The Arrow brand of spray guns are provided with a replaceable glass fuse of size 5x20mm of 800mA rating. Should the fuse need to be replaced, gently lift out the fuse assembly from inside the housing. A rubber sleeve holds together the fuse holder and the cap. Slide out the sleeve and then remove the fuse holder cover from the fuse holder and pull out the fuse. If the fuse is faulty, then replace the fuse with the spare provided or with a new one. Fit back the unit in the reverse manner it was removed. Do not pull the wires and remove the fuse assembly as this may cause loosening of the wire leads.


Each spray gun is packed individual in an inner carton box and held firmly in the box by help of EPS (Thermocol) molded supports to help avoid the unit from being damaged during transit / movement. Please keep the inner carton box and the thermocol supports safely, to enable the spray gun to be repacked by the user and transported to a different place if required.

The unit need not be repacked in the inner box if it is going to be used on a regular basis, but however, if it is required to be stored for longer periods without use, then it is recommended to either repack the unit in the original packing or pack it in a protective air tight plastic cover. Ensure that the solvent jar is totally empty and there are no remaining solvents even in the suction pipe of the spray gun.
