Using Water Jetter Machine As A Pressure Washer; Pressure Washer Operation; Detergent Injector - RIDGID KJ-2200-C Operator's Manual

2. If needed, use sharp thrusts of the hose and hose ro-
tation to help the nozzle through the obstruction.
3. Once through the obstruction, turn the pulse ac-
tuator lever counter-clockwise to the "Pressure"
position. Do not leave the jetter in pulse mode any
longer than needed to pass through an obstruction.
Exces sive use of the pulse feature can cause prema-
ture wear on hoses and system.
Using Water Jetter Machine as a Pressure
Washer
The RIDGID water jetting machines can also be used
as pressure washers with the addition of the pressure
wash package. Use as a pressure washer is similar to
use as a jetter, and those instructions should be used in
conjunction with the following.
1. Locate an appropriate work area.
2. Make sure all equipment has been properly inspect-
ed.
3. Attach the wash wand to the wash wand hose. Al-
ways use hose with a pressure rating at least as high
as the jetter pressure rating. Use a thread sealant to
prevent leaks.
4. Attach hose to the jetter outlet. Make sure the ends
of the hose are securely connected to prevent them
from coming off under pressure.
5. Connect an appropriate water supply, as discussed
earlier, to the jetter.
6. Open the inlet supply valve and squeeze the wash
wand trigger to allow water to flow and purge any
air from the system. Never start the engine without
the water supply turned ON. This can damage the
pump.
7. Make sure that pulse actuator lever is rotated coun-
ter-clockwise in the "Pressure" position.
8. Wash Wand Nozzle Adjustments – By rotating the
nozzle, the wash pattern can be adjusted from a
fine stream to a wide fan type spray. By pulling the
nozzle forward (low pressure) and backward (high
pressure), the pressure can be adjusted. Make sure
that the nozzle is pulled back to the high pressure
position to start operation.

9. Wash Wand Lock Out – the wash wand includes a
lock out on the back of the trigger. Flip the lock out
down to prevent the operation of the trigger when
the wash wand is not in use.
10. With the wand pointed in a safe direction, squeeze
the wash wand trigger to reduce pressure and allow
the engine to be started. Following the starting in-
structions supplied in the engine manual, start the
engine. Allow the engine to warm up. Release the
trigger as soon as the engine starts.
11. With the wand pointed in a safe direction, squeeze
the wash wand trigger. Turn the unloader valve
while monitoring the pressure gauge to adjust the
pressure as desired. Do not exceed the machine
pressure rating. Release the wash wand trigger.

Pressure Washer Operation

1. When using as a pressure washer use both hands to
grip and direct the wash wand for greater control.
Never direct the wash wand at people. High pres-
sure fluid can inject under skin resulting in serious
injury. Never direct wash wand at electrical equip-
ment or wiring to reduce the risk of electrical shock.
2. Control the flow of water with the trigger. Use care
when using the pressure washer. Holding the nozzle
too close to a surface can damage it. Test a small,
inconspicuous area to confirm the settings work as
desired.
3. Do not allow the jetter to run for extended period of
time with the trigger OFF. When the trigger is OFF,
water recirculates in the pump and it causes the
water to heat up. This can cause the pump thermal
overload to open.
4. Once pressure washing is complete, release the trig-
ger and turn OFF the engine as directed in the en-
gine manual. Squeeze the trigger to release system
pressure. Never leave the system pressurized.

Detergent Injector

1. If needed, attach the detergent injector to the outlet
port. Remove the output hose and attach the de-
tergent injector with arrow on the unit pointing the
same direction as the water flow. Use thread sealant
to prevent leaks. Reattach the output hose.
2. Attach the siphon hose to the detergent injector.
Place the strainer end of hose into the detergent
container. Only use detergents designed for use with
pressure washers. Follow all detergent instructions.
Do not spray flammable liquids or toxic chemicals.
Other detergents, solvents, cleaners, etc. can dam-
age the jetter, or cause serious injury.
