3. INITIAL HIGH PreSSure rINSe
Spray the cleaning surface with water to clear off any dirt or
grime that may have collected on the surface . Doing so allows
the detergent to attack the deep down dirt that has worked
its way into the cleaning surface . Before triggering the gun,
adjust the nozzle to a wide fan pattern and slowly adjust it to
the desired spray pattern . Using a wide fan pattern helps you
avoid applying too much concentrated spray to the surface
which can cause damage .
ADjuSTING FAN PATTerN
Adjust the angle of spray coming out of the lance by rotating
the nozzle . The spray pattern will vary from a 0° narrow high
impact stream to a 60° wide fan spray (See Figure 9 ) .
A narrow stream has high impact force on the cleaning
surface and results in maximum deep cleaning in a
concentrated area . However, this narrow high impact spray
can damage some surfaces so use it cautiously .
A wide fan pattern will distribute the impact of the water
over a larger area resulting in excellent cleaning action with
a reduced risk of surface damage . Clean large surface areas
quickly using a wide fan pattern .
Operation
a . If inlet water pressure is over 100 psi, install a regulating
water valve at the garden hose connection .
b . Do not exceed 100° F (38° C) inlet water temperature .
NOTe: The inlet water supply must have a minimum flow rate
of 5 gpm (19 lpm) .
4 . Turn the water supply ON .
never run the unit dry. be sure the water
supply is completely turned on before
operating the unit.
5 . Trigger the gun until water sprays smoothly from the tip
indicating that all air is purged from the system . Lock the
trigger safety latch .
6 . Open the fuel valve by turning the knob counterclockwise
until it stops . Close the choke (if engine is cold) by moving
the choke ring fully to the right . Turn the ignition switch
to “ON” .
7 . Start the engine . Unlock the trigger safety latch on the
gun (See Figure 7) . Grasp the starter rope and brace one
foot on the chassis . Point the gun in a safe direction .
While squeezing the trigger on the gun, pull the starter
rope rapidly and firmly (See Figure 8) . Continue holding
the rope as it returns . Repeat these steps until the engine
starts .
Figure 8 - Start the engine
when pulling the starter rope, make
sure to keep your hand and arm clear of
the engine and cart components.
never let the starter rope return by
itself. doing so could jam the recoil
system.
8 . If the engine does not start after two or three pulls or if
the rope is hard to pull, squeeze the gun trigger to release
the pressure that has built up in the high pressure hose .
Repeat Steps 7 and 8 until the engine starts .
