Assemble according to the supplied instructions, making sure that all of the connections are nipped up tightly enough to form a leak-free seal, but not so tight as to damage the plastic threads. To ready the sprayer for use, turn the pressure release valve on the side of the pump until any residual pressure is released. Then unscrew the pump and fill the tank with a suitably diluted cleaning solution up to the filling line (we provide recommended dilution ratios for all of the cleaning solutions we stock; see the Specification section on the relevant product pages for details). Finally, screw the pump on to the tank and pressurise the system (using 30-40 pump strokes). To spray the cleaning solution, press the button atop the handle on the pump; releasing the button stops the spraying action immediately. The spray pattern can be adjusted by turning the nozzle where the spray emerges. After use, depressurise the system using the pressure release valve on the side of the pump; never leave the system pressurised while in storage, and never depressurise the system by unscrewing the pump from the tank.
Notes on dilution:
Making up diluted solutions is a relatively easy task, but it's worth noting that some confusion can arise from differences in the way that car care product manufacturers quote dilution ratios. Strictly speaking, dilution ratios should be quoted as the number of parts of original chemical in the total number of parts of diluted solution. Accordingly, a dilution ratio of 1:10 would be achieved by making up a solution containing one part neat chemical and nine parts water, i.e. ten parts in total (giving a dilution ratio of one in ten). However, it's far more common for manufacturers to quote dilution ratios in parts dilutant to parts original chemical. Accordingly, a dilution ratio of 10:1 would be achieved by making up a solution containing ten parts water and one part neat chemical, i.e. eleven parts in total (giving a dilution ratio of ten to one). It contrast to the strict definition, this produces a slightly weaker solution, and for this reason we recommend that this latter interpretation is adopted whenever doubt about the ratio arises, as it's far safer to work with a solution that's too weak rather than one that's too strong.
