CLEANING WITH DETERGENTS (OPTIONAL FEATURE):
1. The Detergent Injection feature is an optional feature on this machine.
2. Refer to "Risk of Bodily Injury,", and the Detergent Injector Manual which accompanies part #AW-8300-
0001. Be certain to wear protective safety attire as stated in the warnings.
3. Prepare detergent solution according to label directions. Never pump acids, alkaline, abrasive fluids or
solvents through the unit. Due to the unknown and often corrosive characteristics of many detergents
commonly used in the pressure washer cleaning industry, it is recommended to use only mild detergents
with this unit.
4. Connect the Detergent Injector to the unit as directed in the Detergent Injector Manual.
5. Adjust the amount of detergent desired by locating the adjustment knob at the end of the clear vinyl
hose at the Detergent Injector. Turn the knob completely counterclockwise to set at the maximum
siphon rate.
6. Immerse the strainer into the detergent solution to allow detergent to siphon.
7. Be certain the water supply is completely turned ON.
8. With the trigger gun locked in the OFF position, securely quick-connect the detergent spray nozzle
(#6540° BLACK) into the end of the lance.
NOTE: This injection system is designed to apply detergents under low pressure only. It will not allow detergent solutions to be
introduced into the system unless the detergent nozzle is installed in the lance.
9. To apply solution, unlock the trigger gun and squeeze the trigger. In a few moments a detergent/water
mixture will exit the low pressure nozzle. Start spraying the lower portion of the surface being cleaned
and move up, using long overlapping strokes. Applying from the bottom up helps avoid streaking.
Allow to soak briefly. (Avoid working on hot surfaces or in direct sunlight to minimize the chances of the
detergent drying, which may result in damaging painted surfaces.) Be certain to apply cleaning solution
to a small section at a time.
10. To rinse: lock the trigger gun in the OFF position, securely quick-connect the 40° nozzle into the end of
the lance. Unlock the trigger gun and spray. It will take about 30 seconds to purge all detergent from the
line. For best rinsing results, start at the top and work down.
11. Siphon a gallon of water through the low pressure detergent injection system after each use. This
prevents the possibility of corrosion or detergent residue causing mechanical problems during the next
use.
SHUTDOWN:
1. Turn engine OFF as directed in the Engine Manual.
2. Turn the water supply OFF.
3. Pointing the gun in a safe direction, trigger gun momentarily to relieve any trapped pressure.
4. Once pressure is relieved, disconnect the nozzle assembly.
5. Disconnect and drain gun, lance and hoses.
6. Wipe unit clean and store with gun, lance and hoses in a safe area.
