LOCKING GUN TRIGGER
CAUTION: Gun trigger should be locked when not
in use or whenever adjustments are being made
to gun or nozzle. This will help prevent accidental
discharge of high pressure fluid.

2. Pivot lock up to release trigger.
ADJUSTING SPRAY NOZZLE PRESSURE AND
PATTERN
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,
fingers, eyes or body directly over spray. Do not
point spray toward fragile materials.
Spray nozzle can be adjusted in four ways to obtain best
results.
Pressure Adjustments:
1. For high pressure spray pull nozzle cover toward the gun
handle (A).
2. For detergent spray push nozzle cover away from gun
handle (B). In this position, nozzle sprays at low pressure
and draws detergents into the system if the detergent the
hose is attached and in solution.
Pattern Adjustment:
1. For 0° Pinpoint Pattern-Turn nozzle fully clockwise (C).
2. For 60° Fan-Type Pattern-Turn nozzle cover fully
counterclockwise (D).
3. For Infinate Adjustment-Turn nozzle for desired spray
pattern anywhere between 0° and 60°.
In the high pressure spray position, water pressure can be
varied by turning the pressure adjusting knob (E) clockwise
to increase pressure and counterclockwise to decrease
pressure.
