Perform daily/periodic maintenance as specified in this Owner Manual.
Connect all required hoses.
Connect the cleaning tool to the length of hose required to perform the
cleaning.
CAUTION: Mix tank must be full prior to ignition.
Start engine (choke as required). Engine may be started in either the
run or idle throttle position.
Idle RPM is approximately 2000. Run RPM
is 3100.
NOTE: The low speed (2000 RPM) throttle setting is for “start up”
and “shut down” only.
Do not run the machine for long periods of
time at the “idle” setting. Damage to the throttle solenoid may occur.
Spray the wand to void all air from the system. When the mix tank
begins a fill cycle, the chemical flowmeter may be adjusted to your
desired setting. Set your cleaning pressure at 300 PSI.
NOTE: A chemical flowmeter set at 5 GPH is a 1 to 30 mix ratio and
10 GPH is a 1 to 15 ratio. When the flowmeter is set at 10 GPH, you
will be using what most chemical manufacturers recommend at 5 .
GPH.
Run the machine for several minutes under load (8 to 10“ HG) until
your desired temperature is achieved.
