Surface Preparation
Before starting any cleaning task, it is important to inspect the area for objects that could create a
hazard. Remove any objects from the work area that could be tripped over, such as toys or outdoor
furniture. Ensure that all doors and windows are closed tightly.
Water Supply (Cold Water Only)
Only draw cold water through the washer. For use with cold water supply only. Water hose must be at
least a 1/2” (13 mm) in diameter. Flow rate of water supply must not fall below 2 GPM (gallons per min-
ute) [9.1 LPM (liters per minute)]. Flow rate can be determined by running the water for one minute into
an empty 5-gallon (19 L) container. Measure the volume of water in bucket after one minute. The water
supply temperature must not exceed 104°F (40°C).
ASSEMBLY AND OPERATION INSTRUCTIONS
• Never use the pressure washer to draw in water contaminated with solvents (e.g. paint thinners,
gasoline, oil, etc.).
• Dirt in the water inlet will damage the pressure washer. To avoid this risk, we recommend checking.
• Always prevent debris from being drawn into the washer by using a clean water source and an ad-
ditional
accessory water filter if required.
• To prolong the life of the washer, rest the washer for minutes after every 30 minutes of use.
CAUTION
MACHINE ASSEMBLY
Attach hand cranks onto the hose reel
and cord reel on both sides. Insert in
