Safety precautions and warnings

GROUNDING INSTRUCTIONS

This product must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appro- priate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

DANGER - - Improper connection of the equipment-grounding conductor can result in a risk of electrocu- tion. Check with a qualified electrician or service personnel if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the product - - if it will not fit the outlet, have a proper outlet installed by a qualified electrician. Do not use any type of adapter with this product.

Ground Fault Circuit Interrupter Protection

This pressure washer may be equipped with a Ground Fault Circuit Interrupter (GFCI) on the power cord. This device provides additional protection from the risk of electrical shock. Should replacement of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.

EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong, grounding type plugs and 3-pole cord connectors that accept the plug from the product. Use only extension cords that are intended for outdoor use. These extension cords are identified by a marking „Acceptable for use with outdoor appliances; store indoors while not in use“. Use only extension cords having an electrical rating (volts AND amps) not less than the rating of the product. Examine extension cord before using, and replace if damaged. Do not abuse the extension cord and do not yank on any cord to disconnect. Keep cord away from heat and sharp edges. Always disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.

WARNING - - To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the plug with wet hands.

2.3 Operation

(also see Sec. 3.0, Operating instructions)

High or low pressure (Sec. 4.2)

Generally speaking, high pressure loosens soil, and low pressure moves it.

Attack the „dirtiest“ areas first, with high pressure. Then complete the task with a combination of high and low pressure as appropriate.

Technique (also see Sec. 4.4)

Generally, it’s best not to allow areas still being cleaned to dry before you’ve finished. This is espe- cially true if you’re using detergent. To remove something like chewing gum, use high pressure and „undercut“ it. To gain „reach“ (ie. for the eaves of the house), use high pressure. Experimentation will produce the ideal setting for your cleaning task.

2.4 Safety devices on the machine

Bypass/Overpressure relief

The high pressure side of the pump is equipped with a combination bypass and safety valve. This valve recirculates water back to the low pressure side of the pump when the spray handle is closed or the nozzle is blocked. The bypass/safety valve also ensures that the pump pressure will never exceed the working pressure by more than 300 psi (well within the design strength of the pump). At this pressure, the pump automatically switches from high pressure to bypass mode. The bypass/safety valve also relieves pump pressure when the ma- chine is stopped.

Motor overload protection

The electric motor features overload protection. If an overload occurs (caused by excessive pressure, improper extension cord, or defect), the motor will stop.
