THERMAL PUMP PROTECTION
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
pump pro tec tor engages and cools the pump by dis-
charg ing the warm water onto the ground. This ther mal
de vice pre vents internal dam age to the pump.
CLEANING TIPS
Pre-rinse clean ing surface with fresh water. Place de-
ter gent suc tion tube di rect ly into clean ing solution and
ap ply to sur face at low pressure (for best re sults, limit
your work area to sec tions approximately 6' square
and always ap ply de ter gent from bottom to top). Allow
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 drying, sim ply wet down sur face with fresh water. If
need ed, use brush to re move stub born dirt. Rinse at
high pres sure from top to bottom in an even sweep ing
mo tion keep ing the spray nozzle ap prox i mate ly 1' from
cleaning sur face. Use over lap ping strokes as you clean
and rinse any sur face. For best surface clean ing action
spray at a slight an gle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
dis tance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use
ex treme caution as pressure washer may re move
the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
sur face you plan to clean. High pressure wash a
small area, then check the surface for damage. If no
dam age is found, continue to pressure wash ing.
CAUTION - Never use:
• Bleach, chlorine and other corrosive chem i cals
• Liquids containing solvents (i.e., paint thinners,
gas o line, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will dam-
age the surface being cleaned.
