V Packing Replacement Precautions
(1) Install V packings in the correct direction with the convex side pointing in
the right direction.
(2) Cylinder
⑭
clearance should be such that it can be pushed in by hand.
When it’s too tight, do not use plain washers
⑪
at all or use only one washer.
If the clearance is too tight, cylinder stroke may get sticky.
If the clearance is too loose, suction failure may occur.
(3) To mount the packing retainer
②
, tighten it by hand as far as you can.
Then tighten it further with a spanner for another 15
~ 30
.
If you tighten excessively, operational failure may occur.
If you tighten insufficiently, oil leak may occur.
Proper retightening at the end of service work helps packing to last longer.
When you replace the suction filter
⑧
on page 19, be sure to wear safety gloves
to avoid possible injury.
(1) Always pay attention to pressure
Don’t raise output pressure more than required.
Always lock the trigger of your gun – each time you stop spraying for a break or interruption.
When you found leak from joint,
Bring the pressure down,
Drain the fluid,
Locate the point of leakage,
Retighten.
Use the lowest pressure possible, when:
Flushing the fluid circulation passage in the system,
Circulating fluid.
(Air pressure at about 0.1MPa)
(2) Is the material hose OK?
Is there any sharp bending along the line?
Are hose fittings tight enough?
No hose damage?
No trace of any heavy object placed on the hose?
(3) When changing paints or adding additives …..
When you change paint fluid, thoroughly flush the can with solvent so that no paint residue may
be left unremoved. (Paint residue may cause the nozzle to get clogged.)
When you add additives, do so through the filter.
When you change paint colors, take the suction pipe out of the paint can, pull the trigger
discharging all paint from the system (this way you can save solvent), then flush it with solvent
repeating suction-circulation-discharge circles as many time as it takes to completely flush the
fluid passage from the inlet to outlet. After this, change paint color.
