Nozzle Tubes And Fittings; Checking The Valve Cone In Distributor Valves - Hardi MEGA 230 Operator's Manual

10.1 Nozzle Tubes and Fittings (cont'd)
The O-rings need to be lubricated ALL THE WAY AROUND before fitting
on to the nozzle tube.
HARDI recommends using a vegetable based oil to prolong the life of the
O-ring.
10.2 Checking the Valve Cone in Distribution Valves
Periodically check the distribution valves for proper
sealing.
Flush the sprayer with clean water and open
master on/off and all distribution valves. (Shut
sprayer off)
Remove clip A (Fig. 46) and remove hose B for
the constant pressure device. When the housing is
drained make sure everything is clear from part B
then start sprayer, there should not be any flow of
liquid through the constant pressure passage. If
there is any leakage, the valve cone E must be
changed. (Shut sprayer off.)
Remove clip C, and pull the EC-motor off the valve
housing. Then remove D screw and replace the
valve cone E. Reassemble in opposite sequence.
