MAINTENANCE & STORAGE

NOTE: 

Replacement parts for your pressure washer can be ordered at WENproducts.com. Use only identical 

replacement parts.

HIGH PRESSURE HOSE

The high pressure hose can be easily damaged and should be stored carefully. Do not kink the hose. Do not drive 
vehicles over the hose. Do not expose the hose to sharp objects. Inspect hose for cuts, bulges, or leaks which can 
develop from kinking or wear. If damage is found, replace the hose immediately.

WARNING:

 If the hose is damaged, do not use the unit or try to repair the hose. Always replace with an 

identical part before operation.

SPRAY NOZZLES

Regularly clean the nozzles, preferably after every use, to prevent nozzles 
from clogging and ensure good performance of the machine.

1. Release the trigger, shut off the unit, unplug the power plug and turn off 
the water. 

2. Remove the nozzle from the spray lance. CAUTION: the nozzle may 
spring out when released from the lance.

3.  Use  the  nozzle  cleaner  or  a  small  paper  clip  to  dislodge  any  foreign 
materials that are clogging or restricting the spray tip (Fig. 11). Flush water 
through the back end of the nozzle and spray wand with your garden hose 
for 30-60 seconds to remove any debris.
