Do power pressure washers use gasoline only?
Before filling in a fuel tank, read the manual or gas power washer reviews thoroughly. As a rule, a regular gas is used for a washer. However, there are some models, which use a mixture of gas and oil. The proportion of this solution is indicated in the instruction.
As for fuel type, remember that there may be gas or diesel models. Please double-check it because using diesel instead of gasoline will lead to unit’s damage and it will be costly to fix it. Diesel units are fewer, and used for heavy works and for commercial purpose.
How do you use a gas pressure washer and stay safe?
Using the best gas power washer is quite easy. I’ll describe its design, the main parts and working algorithm.
Unit’s weight vary from 50 to 100 pounds. It consists of an engine, a frame with wheels, a pump, a spray gun, a hose and attachments.
A spray gun is a main instrument for dirt removal. It is usually handy, has a convenient grip handle with a trigger. A unit may have an additional feature – pressure regulations. Press a trigger for water supply; stop pressing a trigger and the flow will strop.
Attachments serve for precise cleaning job: extension wands, turbo nozzles, power brooms, soap blasters.
A spray gun is connected with a hose for water supply. It is produced to withstand high pressure and is connected to an inlet on another end.
Depending on a frame and wheels construction, some gas pressure washers may be used on all terrain. For sturdiness, a frame is made of welded metal and supplied with reliable wheels and never-flat tires.
Any power or electric appliance demands precautions in its operation. Using an electric washer, keep to the rules of water and electricity handling.
Working with fuel-powered equipment use specially designed clothes (coveralls, jackets without buttons, footwear with rubber soles), wear special glasses.
Never direct the water jet on yourself or someone else, it may lead to injure as the water pressure is immense. Some units are equipped with children lockers to protect the kids.
How should you start an appliance?
After reading a manual, finding all parts, filing in and checking all liquids, it’s just the time to start your job!
Plug your gas pressure washer into the source of water. Check if there is no leakage and all parts are tightly connected. Test flow to remove stale water, the hose should be clean.
Engine start may require some practice. Prime the carburetor using a choke or prime bulb. Than make a pulling movement with a cord, from 1-2 to 15-20 depending on a gas pressure washer model and your skills.
Commence the cleaning jobs.
What is the best pressure washer, gas or electric?
Both electric and gasoline types of pressure washers may easily take care about your concrete paths or decks. They will do this more effectively than a garden hose having 75 times less water pressure and spending 80 times much water quantity. However, there are 2 significant differences between electric and gas one, the power source and comfort. An electric pressure washer is powered by electricity. The pros are that it is lighter; it works silently and is environmentally friendly. But the cons are that it possesses a cord, its working zone is restricted and the power is not enough for commercial usage. Read some gas power washer reviews and you will learn that a gas washer possesses a powerful fuel engine, have no cords and may reach any surface and perform any hard cleaning job.
How long does the best gas powered pressure washer live?
Generally, 2 main parts of an appliance provide its long life, a pump and an engine. Their reliability rests on the quality and price. Pumps of low-cost units will not live longer, than 50-100 hours. Do not save on quality and buy the best gas powered pressure washer in case you need it for business purposes. Usually heavy-duty units are expected to serve longer. Average life expectancy of high-quality engine of the costly units are 300 – 3000 hours.
Try to find out availability of spare parts in advance. You may prolong your unit’s operation by replacing a broken part.
For example, the engine may not work due to carburetor contamination or a part brake. In this case, you will not be able to start an engine. Check a carburetor then, and provide necessary maintenance, cleaning or part replacement.
Store your gas pressure washer in dry place keeping to an appropriate temperature regime (garage, hangar, shed) as indicated in the manual.
What kind of oil do we fill in a gas pressure washer?
Unlike electric power unit, a gas pressure washer must be maintained. This means multiple operations, e.g. fuel filling in and oil check. Read gas pressure washer reviews or a manual before starting any manipulation with the appliance. It must state which type of fuel and oil should be applied.
Oil check is easy to do either by a special window or by dipstick after opening a cap of an oil tank. Make sure it reaches necessary level. If not, add exact amount trying not to pore extra as it is dangerous for unit performance. The most common type of oil is 10W30, which suits many gasoline power washers in the temperature range below 4°F. This is all-purpose engine oil. However, read the manual to check appropriate and low consumption oil for your device and work conditions.
Always check liquids before start of work. Necessary level of oil will prolong life of your device.
What are good PSI and other main features for best gas pressure washers?
The main power indication of any gas pressure washer is its PSI number. Pressure on Square Inch (PSI) is the measurement of a unit’s output. The higher this number is, the more powerful an appliance is. Average figures are from 2,500 to 3,500. Another indication of the output is GPM (gallons per minute, 1.9-2.6 average indications). If you need a machine to cope with an outstanding work, like paint stripping, heavily embedded mildew deleting or cleaning after construction works, select an item with both big numbers. Bigger PSI and lower GPM means a gas power washer is designed for simpler residential works.
Cubic capacity of an engine demonstrates a power unit fuel volume.
Weight and dimensions demonstrate the power capacity of a unit. The bigger overall dimensions – the more powerful unit is. A unit with bigger capacity of the fuel tank is more convenient, as requires less filling-in operations.
Is it dangerous to run gas pressure washers without water?
Water flow must be provided obligatory or it may lead to pump damage. In case you made a mistake and failed to switch on water supply, pump work may be checked by starting the unit and triggering a gun. If there is no water pressure, a pump may be damaged and require maintenance. If water is running, so it’s ok.
