OPERATING INSTRUCTIONS
CLEANING WITH DETERGENTS:
. Prepare detergent solution according to label directions. Never pump
acids, alkaline, abrasive fluids or solvents through the unit.
2. Some units are equipped with adjustable detergent knobs. Locate the
clear vinyl hose which leads to the pump head.
a. If your injector is equipped with an adjustment knob on the pump
head, you may adjust the amount of detergent desired by turning
the knob completely counterclockwise to set at the maximum siphon
rate.
b. If your injector is not equipped with an adjustment knob, the detergent
ratio is preset and cannot be adjusted.
3. Fully immerse the detergent strainer into the detergent solution.
4. With the trigger gun locked in the "OFF" position, securely quick-connect
the detergent spray nozzle (#6540° BLACK) into the end of the wand.
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 assembly installed in
the wand.
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. DO NOT allow detergent solution
to dry on the surface. (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, securely quick-connect
the desired high pressure nozzle into the end of the wand. 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.
SHUT-DOWN:
. DO NOT close the choke to stop the engine. Backfire or engine
damage may occur. 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. Disconnect and drain the nozzle assembly, gun, wand and hoses.
5. Store complete assembly in a safe, non-freezing area.
