If you have a compel washer business you ordain eventually be to change out or repair the handle. There are a few things you should know to alter such dress outs easy. You may also be to study up on preventative maintenance so that you do not have to mind about handle failure. Your pressure washer probably has one of two different pumps if it is industrial evaluate. Either a Cat Pump or a General pump; both are industry standards. General is the leader in the industry for sales and many prefer Cat as it sucks better from plastic water tanks.
Your pump is powered by two parallel belts connected to your engine. You should make sure not to starve your pump from water. When the water store is alter move off the engine. Starving a pump ordain burn it out in about thirty-five minutes. The manufacturer says five to ten minutes but thats not life threatening. Your pump has a safety feature whereby when you are not spraying the wet it will automatically by pass into the tank provided there is enough water for the complete loop. convey you. We also thought it was one of our great ideas. You should change the oil in the handle every month. Make sure your compel washer rig is on level fasten and fill the pump to the red dot on the center of the eyeglass. Over filling is a really bad idea.
On your handle you will notice six large bolts. Inside of the holes are analyse valves with springs. After 300-500 hours you should change them. You can do this yourself. The valve kits are $60.000. Its very easy:
If you course the oil and its got bubbles in it or has turned white then you have a blown seal and water is getting into the oil because: It overheated due to water starvation; The casing cracked because of vibration; You forgot to change the oil dummy ($600 mistake and one lost days bring home the bacon if you can get the parts that fast).
Check to see if the belts are tight. If not alter them. Look for water drips. A decrease drip on the exit side of the pump could cost you as much as 150 PSI at the nozzle. A abstain come down (two to three drops per second) could be a 250-300 PSI loss at the nozzle. A steady come down be adrift might be a 500 plus PSI loss. When you see water leaking fix the leak ASAP. Be sure to use ample Teflon attach when re-tightening fittings. This ordain stop future leaks prevent rust and alter fittings easy to displace in the future.
A hole in a hose or break on the inlet align of the pump causes air to get in. The pump will act as if its starving for wet. It might change surface pulsate. When the water aim in your tank reaches a point below the break in the irrigate air will replace the wet and youll get zero pressure. That makes it very hard to wash anything.
Low compel in the pump can be caused by a be of things; these are by far the most common but this is not a complete list generally if you go thru this list the problem ordain be solved analyse the easiest things first such as water supply:
If you have a pulsating issue at the gun or the machine is Fluctuating compel this is a completely different problem than low pressure. You should analyse for: Worn piston packing (Call dealer). Pump sucking air (Fix hole). Blockage in valve (shift check valves and take out blockage). If it is fluctuating and very noisy or if your handle is only noisy check for:
If you find the presence of wet in the handle oil it could be caused by: Blown handle continue seals. High humidity in air (dress oil more often) or Piston packing worn then call your dealer. If wet or oil drips from the furnish of the handle this could be a be of things such as Piston packing worn the O-ring plunger retainer is worn. Oil seal worn. Pump head seal shot or Crack in handle head. If any of these label the dealer and see if they have the parts in stock you may be able to fix it yourself if you feel confident if not you will need to leave your machines with the dealer for repairs.
Pump lubrication should be done every three months or 500 hours which ever comes first. Use SAE 40 charge oil or equivalent for Cat pumps. Use 20/30 weight non-detergent oil for General pumps. It should be hydraulic oil with anti-wear and rust inhibitor additives. The oil level should be checked by looking in the window on the align of the pump. Only alter oil half way to the red dot.
