CHANGING NOZZLE
CAUTION: High pressure spray can cause serious
injury. Keep away from spray. Never point the gun
at yourself or anyone else. Never put your hand,
ngers, eyes or body directly over spray. Do not
point spray toward fragile materials.
CAUTION: To avoid injury from escaping uids
under pressure, relieve the pressure in the system
by stopping the washer and depressing gun
trigger. Lock trigger before changing or adjusting
nozzle.
Be sure nozzle is tightly attached before operating
to help prevent nozzle release.
1. Retract locking ring (A) of quick-connect tting and
remove nozzle (B).
2. Insert nozzle and push ring forward and lock nozzle in
place. Be sure nozzle is fastened to wand.
SELECTING THE PROPER NOZZLE
Pressure and volume are partially determined by the size
of the orice in the nozzle. Standard numbers are on the
nozzles to indicate spray pattern and orice size. For
example, a nozzle stamped 2503 has a 25° spray pattern
and a 3.0 orice.
