System Assembly
Mount the Spray Valves
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
installation 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.
