SAFETY
Motors are air cooled.
It is important to ensure that machine is operated in a well-
ventilated area where it can draw a steady supply of fresh air. The arrows below show
an example of locations for air intake on an engine.
Pumps are water cooled.
When the machine is running, ensure the trigger of the gun
is pressed to allow a constant flow of fresh water into and out of the pump.
Do not let
the machine run for more than 30 seconds without pressing down on the trigger.

Most pumps are protected by a
thermal valve.
The thermal valve releases water if a
pump starts to run too hot. It will prevent catastrophic heat failure. However, the pump
may have suffered damage and need maintenance, repair, or replacement. If it does not
reset and continues to leak water, the thermal valve may need to be replaced.
