Scale Removal
Running an acid solution through the coil is a solution for scale buildup developed in the early days of steam cleaning. Since water in a steam cleaner is heated to 325 degrees Fahrenheit and beyond, impurities precipitate out faster, and scale can be more of a problem than in a hot water high pressure cleaner. (more…)
April 6th, 2012 vdate Introduction To Gasoline Engine Care and Maintenance
Proper care of a cleaner’s gasoline engine can go a long way to keeping it in continuous operation with minimal downtime. One-or two-cylinder, general purpose internal combustion engines are widely used to power portable high pressure cleaners. (more…)
February 7th, 2012 vdate Introduction To Electric Motors
Electric motors power the majority of hot water pressure cleaners in service today. Many electric motors suitable for use in high pressure cleaning are available. Unsuitable motors, however, are often used. The most suitable motors are totally enclosed or washdown duty motors especially designed for use in damp environments. (more…)

Pressure washers are ideal for cleaning most types of farm equipment, barns, wheel tractors, sprayers, seeders, reapers, trucks, plows, compactors, hay equipment, grain drying and milk drawing equipment. (more…)
October 6th, 2011 vdate Rebuilding The Flow-Actuated Unloader Valve
The K-5 and K-7 designs are typical of flow unloaders. A number of manufacturers make unloaders of this type including Suttner, Giant, Cat and others. This unloader type can be rebuilt using a vise and minimal tools. Care should be taken to not scratch or damage the unloader during rebuilding. Special care should be taken to not damage internal surfaces and parts. (more…)

The Equipment Check
The Comprehensive Equipment Check is a step-by-step procedure for determining if a cleaning system is in proper working order. This check goes through the cleaner’s major systems helping to detect maintenance needs and potential service problems. The equipment check should be performed monthly or after any period of particularly heavy usage, especially if the equipment was used in a harsh or hostile environment. (more…)

Types Of Chemical Delivery
Getting the cleaning chemical to the surface to be cleaned requires the chemical solution either be sprayed on the surface separately or delivered along with the water spray from the cleaning system. Most high-pressure cleaners allow for automatic delivery of chemicals through the system. (more…)

Protection Against Excessive Pressure
The pressure relief or pop-off valve is a simple pressure-relieving safety device. When system pressure reaches a predetermined point, the valve opens and releases water from the system to the atmosphere. The pressure relief valve functions as sort of a circuit breaker for water. (more…)
