BISON Pressure Washer Frequently Asked Questions

To properly store your pressure washer, you must first drain the gas from its motor and run it dry. The pump should have antifreeze run through it, and left inside the pump. This will protect the pump from freezing as well as protect the pump internally from corrosion caused by the water. In addition, it lubricated and protects the seals from drying out, making it ready to use at a moment’s notice. Disconnect all the hoses from the machine, empty them of liquids, and wipe them down. Store your pressure washer in a cool, dry space.

Refer to your User Manual for instructions on which oil to use for which part of your pressure washer. Most pumps use a 30W non-detergent oil.

There are many possible explanations for why your pressure washer isn’t reaching full pressure. Your packings could be worn down, causing your pump to be less effective and have less of a seal around its openings. Your inlet water valve could be clogged, or the filter could be plugged, and not enough water could be getting into the machine. There could be a kink in the hose. Etc. Contact our exceptional customer service team with other possible questions about why your pressure washer isn’t reaching full pressure.

1. Always disconnect your spray wand from the gun before cleaning your nozzles!
2. Clear the nozzle with a small rigid piece of wire such as a paper clip.
3. Flush the nozzle backwards with water.
4. Reconnect the wand to the gun
5. Restart the pressure washer and depress the trigger on the spray gun.
If the nozzle is still plugged or partially plugged, repeat number 1-4.

If the previous procedure does not clear the nozzle, replace with a new nozzle.
