Trigger Safety Latch
WARNING
To reduce the risk of serious bodily injury
including fluid injection, splashing in the eyes or
on the skin, ALWAYS engage the trigger safety
latch whenever spraying stops, even for a
moment.
In the engaged position, the trigger safety latch
prevents the gun from being triggered
accidentally by hand or if it is dropped or bumped.
Be sure the latch is pushed fully down when
engaging it or it cannot prevent the gun from being
triggered. See Figure 2.

Installing and Changing Spray Tips
To reduce the risk of serious bodily injury, including

fluid injection or splashing in the eyes or onto the
skin, use extreme caution when changing spray
tips. ALWAYS follow the procedure below.

2. Point the gun and wand away from yourself and
anyone else.
3. Without holding your hand over the spray tip (A),
pull back the quick coupler ring (B). Remove the old
tip and/or install a new one, and then release the
ring. See Figure 3.
4. Be sure the tip is secure before starting to spray

never operate the pressure washer without a tip
securely mounted in the quick coupler.
