CONNECT THE ELECTRICAL MOTOR CABLE
AUCTION: Check the electrical supply voltage and frequency (HZ) Correspond to those specified on the appliances data
plated. The appliances should only be connected to a mains power supply equipped with an adequate earth connection.
1. The motor should be grounded properly. Grounding structure is in the right lower part of the junction box, if necessary, the foot
of motor or flange fastening bolts could be used for grounding.
2. Please reference the blow connecting method for the different motor.
5. Protection and short-circuit protection device should be used by the motor. Adjust all parameters of heat protection and short-
circuit protection device according to the numbers written in the name plate of the motor.
6. When the frequency is 1% at variance of rated frequency or the voltage of power is 5% at variance with rated voltage, the motor can
not maintain working at rated wattage. For consistent working motor , no overload is permitted.
7. When operating at no load or normal load, there should be no intermittent sound stranger noise or vibration, The temperature of
bearing should not be over 95 C

6.DO NOT get closer than 6 inches when cleaning automobile tires
SPRAY NOZZLE MAINTENANCE
A pulsing sensation felt while squeezing the spray gun trigger may be caused by excessive. Pump pressure . The principal cause of
excessive pump pressure is a nozzle colgged or restricted with foreign materials, such as dirt, etc. To correct the problem, immediately
clean the nozzle.

springs back into place when you release it. Put the trigger lock in the ON position and test the trigger .The trigger should get
locked and should not get pressed.
CLEANING THE NOZZLE
If the nozzle becomes clogged with foreign materials such as dirt, excessive pressure may develop.If the nozzle becomes
partially clogged or restricted the pump pressure will pulsate, clean the nozzle immediately by follow the given below instructions
:
1. Shut off the power washer and turn off the water supply.
2. Pull trigger on gun handle to relieve any water pressure.
3. Disconnect the spray wand from the gun
4. Remove any obstructions with the nozzle cleaning tool provided and back flush with clean
water.

POWER WASHER TERMINOLOGY
PSI – pounds per square inch, the unit od measurement for water pressure.
GPM – Gallons per minute.
CU - Cleaning units, GPM X PSI
Bypass mode – In bypass mode, the pump recirculates the water because the trigger of the spray gun is not being
pulled. If unit is left in bypass mode for more than two minutes, the water temperature will rise to a dangerous level and
could damage internal components of the pump.
NOTE – Any damage to pump due to these causes will not be covered under warranty.
Chemical Injection system – Mixes cleaners or cleaning solvents with the pressurised water to improve cleaning
effectiveness.
Thermal relief valve – In an effort to prevent extreme damage, pumps are equipped with a thermal relief valve. This valve
will open when the temperature inside the pump rises too high. This valve will then release a gush of water in an effort to
lower the temperature inside the pump. Immediately after this occurs, the valve will close.
