  If your Benchmark Portable Generator's engine won't start, there could be several reasons. First, ensure you have gasoline in the tank and that the engine oil level is adequate; add fuel or oil as needed. Check that the choke is in the correct 'Start' position. If you've pulled the recoil cord twice without success, squeeze the trigger to release built-up water pressure. Also, make sure the spark plug cap is securely connected and that the spark plug isn't fouled; replace it if necessary.

Why Benchmark Portable Generator has inconsistent or low pressure during use?

  Mario GrayAug 21, 2025
  If you're experiencing inconsistent or low pressure with your Benchmark Portable Generator, start by checking the water supply. Ensure there are no kinks, leaks, or blockages in the garden hose, and that you're using a minimum 3/4" hose. Fully open the water supply tap. Also, inspect the nozzle for clogs and clean it if necessary. Check all connections on the spray gun and use sealant tape if there are any leaks. Squeeze the trigger handle to remove any air in the line. Clean the inlet filter in warm water if it's clogged. Make sure the water supply temperature is not over 100F. If the problem persists, it could be a faulty pump.

  If your Benchmark Portable Generator is not reaching high pressure, first check the nozzle. If the low-pressure black detergent nozzle is attached, remove it and attach a high-pressure nozzle. Ensure you have an adequate water supply, using a 3/4" diameter hose minimum. Inspect the hose for leaks, kinks, or blockages, and ensure the water supply tap is fully open. Clean the water inlet filter if it's clogged. Check the nozzle for any obstructions. If you are using a high pressure hose, make sure that it is not longer than 100 feet (30m).

  If the detergent is not mixing with water in your Benchmark Portable Generator, ensure that the spray wand is set to low pressure by attaching the black low-pressure nozzle. Make sure the chemical screen is fully submerged in the cleaning solution. If the chemical is too thick, dilute it to the consistency of water.

  If you notice water leaking at the spray wand connection or pump of your Benchmark Portable Generator, begin by tightening all connections. If the leak persists, the spray wand o-ring may be worn and require replacement. For issues related to piston packings, pump o-ring, or pump head/tubes damaged from freezing, contact technical support.

  If your Benchmark Pressure Washer isn't reaching high pressure, there might be a few reasons: * The low-pressure black detergent nozzle might be attached. Remove it and attach a high-pressure nozzle. * Your water supply might be insufficient. Ensure you're using a 3/4" diameter hose minimum. * The water supply could be restricted. Check the hose for leaks, kinks, or blockages, and make sure the water supply tap is fully open. * The water inlet filter might be clogged. Remove the filter and rinse it in warm water before reinstalling. * The nozzle might be obstructed. Refer to the nozzle cleaning instructions. * The high-pressure hose might be too long. The maximum length should be 100 feet (30m).
