lease all pressure before disassembly or removal of any part.
FOR CL ANING: Use solvent with highest possible flash point,
that is compatible to material being used.
1. ShutĆoff a r pressure to pump and rel eve l qu d pressure n system
through manual rel ef valve at outlet f lter on those models

9. Start pump w th gun tr gger retracted, ncrease a r pressure unt l
suff c ent pressure s obta ned to cause pump to cycle approx mateĆ
ly 25 cycles per m nute. Purge gun approx mately one m nute wh le
nterm ttently operat ng tr gger. Adjust pack ng gland f necessary to
prevent leakage.
10. ShutĆoff a r pressure to pump and pull gun tr gger to rel eve presĆ
