sHutdoWn:
. Close the valve on the L.P-Gas tank. Shut the pilot valve off by depressing the
gas valve control knob and turn it off.
2. Squeeze the trigger and discharge the water for a period of three minutes to
cool the heat exchanger and high pressure hose. (Insufficient cool down period
of the high pressure hose will cause excessive wear and eventual rupturing of
the hose.)
3. Turn the control switch to the "OFF" position to stop the pumping unit.
4. Trigger the gun momentarily to relieve trapped pressure.
5. Secure the tank to the unit for transport.
cleaninG WitH deterGents:
Connect the Detergent Injector to the unit as directed in the Detergent Injector Manual
#AW-8300-0000.
1. Refer to “Risk of Bodily Injury,” pg. 9, and the Detergent Injector Manual
which accompanies part #AW-8300-0000. Be certain to wear protective
safety attire as stated on pg. 7.
2. 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.
3. Adjust the amount of detergent desired by locating the adjustment knob
at the end of the clear vinyl hose near at the Detergent Injector. Turn the
knob completely counterclockwise to set at the maximum siphon rate.
4. Immerse the strainer into the detergent solution to allow detergent to
siphon.
5. 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.
6. 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.
7. 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.
8. 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.
