Operate the Pressure Washer
Step 3- Use the high pressure lance (continued)
CAUTION!
- Jet spray adjustment is very aggressive. Do not adjust while spraying. Switch the machine off when
interrupting your work for extended periods of time.
- The high-pressure pump starts running as soon as you operate the hand-held spray gun. The high-
pressure pump stops running as soon as you release the trigger on the hand-held spray gun.
3. Use with adjustable spray lance, 180 degree rotation of the nozzle. It takes a couple of seconds for
the spray to adjust to setting.
The trigger gun safety lock prevents the trigger from being engaged accidentally and ensures the trigger
gun cannot be locked in the ON position.
Without turning the gun, adjust the spray to desired angle by turning the nozzle with 180° marking as
shown.
