Operation
6. Pull the starter rope to start the engine. Brace one
foot on the pressure washer cart, and pull the
starter rope out quickly.
CAUTION
Do not allow the starter rope to snap back against
the engine. Let the rope recoil gently to prevent
damage to the recoil mechanism.
NOTE: For easier starting, have one person start
the pressure washer while another person triggers
the gun.
If the engine is cold, start the engine with the
choke completely closed. In cool weather, you
might have to let the engine run with the choke
closed for the first 10 to 30 seconds. In warm
weather, open the choke completely as soon as
the engine starts.
If the engine is warm, start the engine with the
choke completely open or partially closed. When
the engine starts, open the choke completely.
Trigger Safety Latch
WARNING
To reduce the risk of serious bodily injury, including
fluid injection or splashing in the eyes or on the
skin, always engage the trigger safety latch when
you stop spraying 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, or it will not prevent the gun
from being triggered. See Fig. 1.

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
current tip and/or install a different one. Then push
back the ring. See Fig. 2.
4. Pull on the tip to be sure it is secure before you
spray again.
