SAFETY FEATURES
I.) Safety Relief
The safety relief valve is a backup safety feature. If the
unloader malfunctions, the safety relief valve will open
and relieve system pressure.
WARNING: If the safety relief valve ever discharges
water, turn the engine off and do not use the
machine. See a dealer or call Customer Service at
1-800-270-0810.
II.) Thermal Protector
The thermal protector protects your pump from
overheated water. When the spray gun trigger is
released, the pump DOES NOT stop pumping. Water is
circulated through the unloader valve and pump. The
circulating water heats up quickly. The thermal protector
discharges water when it reaches 140°F preventing
pump damage .
