OPERATING INSTRUCTIONS
CLEANING WITH DETERGENTS:
1. Refer to "Detergent Cleaning Precautions" pg. 6. Be certain to wear
protective safety attire as stated on pg. 10.
2. Prepare detergent solution according to label directions. Never pump
acids, akalines abrasive fluids or solvents thru the unit.
For Models with Chemical Tank:
3. Pour prepared detergent solution into chemical tank mounted on the unit.
For Models without Chemical Tank:
3. Connect the detergent hose to the unit as shown on page 8. The
detergent ratio is preset and cannot be adjusted. Immerse the detergent
strainer into the detergent solution to allow detergent to siphon.
4. With the trigger gun locked in the "OFF" position, remove high pressure
nozzle and replace with low pressure detergent nozzle at the end of the
wand away from the gun.
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 low pressure nozzle is being used.
5. 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 rinse a small
section at a time.
6. To rinse; lock the trigger gun in the "OFF" position, replace the low
pressure detergent nozzle at the end of the wand with high pressure
nozzle. 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.
7. 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, wand and hoses.
6. Wipe unit clean and store with gun, wand and hoses in a safe, non-
freezing area.
