The MC785M-WF is recommended for spray widths from 2.0" to 6.0".
Note: Spray width coverage may vary depending on the viscosity and surface tension of the fluid.
Mount each valve with the mounting clamp (7021742)
provided, or use the 6 mm mounting hole in the valve
body to attach the valve to an alternative mounting bracket.
Note: Optional valve mounting fixtures provide easy instal-
lation of the valves without the need to drill or fabricate
attachment hardware. See page 27 for further information.
To ensure proper lubrication coverage, mount the
MC785M valve so the tabs on the air cap are in line with
the stock as illustrated. Use the valve alignment tool
(7023866) shown on page 27 for precise valve alignment.
IMPORTANT: If you loosen the air cap
retainer nut to reposition the tabs, be
sure to retighten the nut with a
wrench before operating the valve.
The width of spray coverage is determined by the distance
between the valve nozzle and the stock, as shown in the
chart below.
