MAINTENANCE
AFTER USE
After use, the sprayer should be flushed thoroughly with clean water until the
discharge runs clear, to avoid the possibility of blockages from product
residue, or any cross-contamination between different products.
After extensive use, unscrew the
trigger body and remove and clean
the filter fitted inside the trigger
assembly.
If not used for long periods or used
continuously for several days, add a
light smear of vaseline to the piston
cups and other moving parts to
reduce wear and assist free
movement. Store in a cool place out
of reach of children.
