If you run the engine on your pres sure wash er for 3-5
min utes with out pressing the trig ger on the spray gun,
cir cu lat ing water in the pump can reach high tem per a-
tures. When the water reaches this tem per a ture, the

charg ing the warm water onto the ground. This ther mal
de vice pre vents internal dam age to the pump.
CLEANING TIPS

ter gent suc tion tube di rect ly into clean ing solution and

de ter gent to re main on sur face 1-3 min utes. Do not
al low de ter gent to dry on sur face. If sur face appears
to be dry ing, sim ply wet down sur face with fresh wa ter.

area should be cleaned to test spray pattern and
dis tance for maximum cleaning results.

ex treme caution as pressure washer may re move
the loose paint from the surface.

no dam age is found, continue to pressure wash-
ing.
