SAFETY - COOLING INFORMATIONY
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.
DIRECT DRIVE
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.
