OPERATING INSTRUCTIONS
CLEANING WITH DETERGENTS:
1.
Refer to "Detergent Cleaning Precautions" pg. 6 before working with
detergents. Be certain to wear protective safety attire as stated on pg.
10.
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 Mi-T-M
®
detergents with this unit.
3.
Some units are equipped with adjustable detergent knobs. Locate the
clear vinyl hose which leads to the pump head. You may adjust the
amount of detergent desired by turning the knob completely
counterclockwise to set at the maximum siphon rate.
4.
Fully immerse the detergent strainer (14) into the detergent solution.
5.
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 nozzle assembly is in the low pressure
detergent mode.
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. 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.
7.
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.
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.
