Maintenance
Regular Service Check Up
To prolong the life of your pressure washer, it is important to maintain regular servicing.
Check pump pressure
A drop in water pressure may be due to wear in a component or a restriction in a water line that could cause pump cavitations, damaging the water pump and other pressure washer components. Excessive water pressure would indicate that a component is failing or miss-adjusted, and could cause serious damage to components or injury to the operator.
Check pump volume
A loss of pump volume could indicate the development of a problem in the pumping system of your pressure washer. It could be as simple as a restriction in the plumbing, or it could be the start of a component failure.
Check nozzle
The restrictive hole in the nozzle creates the water pressure intensity. As the hole wears, it reduces the performance of your pressure washer.
Check pump crankcase oil
The pump oil lubricates the crankcase components. Low oil levels could cause a premature failure or scratching of the crankcase components, and can cause the oil to overheat and lose its lubrication. We recommend that you change the pump oil after the first 50 hours of use, and then every 3 months or 300 hours.
Check engine crankcase oil
The crankcase oil lubricates the engine components. Low oil levels could cause the oil to overheat, break down and lose its lubrication.
Check hoses for damage
The high-pressure hoses contain a wire braid that can become damaged over time. If the wire breaks, it can cause the hose to leak or injury to the operator.
Check lance & gun for damage
The trigger gun and lance must be checked for common wear and tear that could cause an unsafe working environment for operators of high pressure washers.
Check detergent supply & metering valve
The metering valve and hoses supply the correct detergent dilution ratio for optimum cleaning power. Worn or damaged components could cause air to be pulled through the system, damaging other components, such as the pump. Incorrect metering of the detergent may result in overuse of soap, which can increase the cost of operation.
Check for coil scaling (hot water pressure washers)
Scale build-up causes nozzle pressure loss-which can damage the pump and its components. Scale build up usually is caused from lime and mineral deposits.
Soot can develop on the outside of the heating coil if the fuel pressure changes, or if something else affects the air/fuel mixture of the combustion. Soot is a sign of a combustion problem.
Check pressure valve
The pressure valve "sets" the pressure limits when the trigger gun is pulled and released on your power washer. If adjusted too low, it will reduce the operating pressure of the system. An unloader valve that is adjusted too high will increase the spike pressure of the system.
Check thermostat for proper cycling
The thermostat is designed to cycle the burner ON and OFF to maintain the set operating temperature. If the thermostat fails, it may cause severe over heating damage.
Check for contaminated fuel tank & flush if required
Water, condensation and other contaminants in the fuel will damage components and affect the fuel pressure, which can result in expensive repairs to your power washer.
Check fuel filter
The fuel filter can trap water and contaminants in the fuel line, after the fuel tank, if it became contaminated. If caught in time, it could be cleaned and flushed from the system.
Check engine air filter
A dirty air filter may reduce the engine performance and the cleaning ability of the pressure washer. Clean and replace the air filter as necessary.
Check engine spark plugs
The condition of the engines spark plugs should be checked and replaced if necessary.
Check engine fuel filter
The engines fuel filter will need to be cleaned and/or replaced periodically to maintain optimum performance of your engine.
