must be at least 4 gpm (15 l/min).

Thermal Protector Feature on the pump.
When the gun has not been in use for 4 or 5 minutes the pressure in the pump builds and the internal water gets
hot. When the pump water temperature reaches 140°F the thermal protector will release a trickle of water onto the
ground to ensure that cooler fresh water circulates through the pump to protect it from heat damage.
• The muffler and other engine parts become very hot.Do not touch with bare hand.
• If you spray too close when using a high pressure spray tip, you could damage the surface being cleaned.
IMPORTANT:
WARNING:
Using and changing spray nozzle tips:
1. Installing or changing nozzles. Pull back on collar, insert new spray tip and
release collar. Tug on spray tip to ensure it is securely connected to the wand.
2. Pull back collar on quick–connect coupler and pull current spray tip off. Storing
nozzles in the designated holder will help to prevent debris from clogging the
tips.
3. Selecting the proper spray tip to tackle the job:
