The EASY!Force | | | | trigger gun is built | | | | in a way which sees: | | | | | | | | - The water control | | | | trigger at the | | | | back of the | | | | handle instead of | | | | the front. | | | | | | | | - Recoil from the | | | | water pushes the | | | | trigger on the | | | | back of the | | | | handle into the | | | | middle of the | | | | hand. | | | | | | | | - This eliminates | | | | the need to form | | | | a fist and pull a | | | | trigger which | | | | makes for a zero | | | | holding force | | | | required. | | | | | | | | The **red section** | | | | in the image | | | | highlights all areas | | | | that are under stress | | | | when using a | | | | conventional trigger | | | | gun. | | | | | | | | The **green section** | | | | in the image | | | | highlights parts of | | | | the body that are | | | | under less stress due | | | | to the open-hand | | | | nature of pressing | | | | the water-control | | | | trigger. | | | | | | | | hearing protIf | | | | operating in an | | | | enclosed area, or for | | | | an extended period of | | | | time, hearing | | | | protection is | | | | required. Also, be | | | | aware of any fumes | | | | generated by the main | | | | unit. | | | | | | | |  | | +-----------------------+-----------------------+-----------------------+ | 9 | **Damage to painted | | | | or sensitive | | | | surfaces.** | | | | | | | | A surface can be | | | | damaged when the jet | | | | is too close to the | | | | surface, or an | | | | unsuitable spray | | | | lance is used. | | | | | | | | Maintain a minimum | | | | spray distance of | | | | **30 cm** when | | | | | | | | cleaning painted | | | | surfaces. | | | | | | | | When cleaning any | | | | machine belts or | | | | conveyors, use a low | | | | pressure setting and | | | | maintain at least | | | | **40 cm** spray | | | | distance so to not | | | | damage the belt. | | | | | | | |  | | | | Always | | | | wear safety glasses | | | | when spraying plant/ | | | | machines to prevent | | | | foreign objects | | | | impacting the eyes. | | +-----------------------+-----------------------+-----------------------+ | 10 | **Breaks in |  | | | | | | | When stopping for a | | | | break, secure the | | | | trigger gun.
