NOZZLE SELECTION & INSTALLATION:

1.  Your Rotary Surface Cleaner will come installed with one set of 2502.5  

 nozzles.

a.  The minimum orifice size to be used in your Rotary Surface Cleaner is  

half that which is being used in your pressure washer.  Example:  If your  

pressure washer uses a size 5 orifice, you will need to use a size 2.5  

orifice in your Rotary Surface Cleaner.  (Two nozzles are inserted in the  

Rotary Surface Cleaner, therefore;  two nozzles x size 2.5 orifice = size  

5 orifice.)

b.  The nozzles being used should have a 15°-25° spray pattern; anything  

less than a 15° spray pattern can damage the area being cleaned.   

Anything more than 25° may not allow the bar to rotate.

2.  Nozzles should be screwed into the rotating bar.  The spray fan should be 

parallel to the Rotating Bar.  (See figure at right.)

UNIT ASSEMBLY:

1.  Line up the holes on the lower part of handle (7) with the holes on the cover 

assembly (4).

2.  Insert the clevis pins (5) through the handle and cover holes and attach to the 

bridge pins (6).

3.  Attach the upper handle (9) by lining up the hole in the upper and lower handle. 

Push the clevis pin (8) through the aligned hole and attach to the bridge pin (6).

4.  Quick connect the Rotary Surface Cleaner hose assembly to the handle center 

and to the swivel located on the unit base.

SET-UP:

1.  Locate the high pressure discharge hose on your pressure washer and  

ensure it is securely  connected to the water outlet of the pressure washer.  

Quick connect the other end of the high pressure discharge hose to the gun on 

the Rotary Surface Cleaner.

2.  Connect the water supply hose, one end to your pressure washer, the other end 

to a pressurized water supply.

SURFACE PREPARATION:

1.  Clear any loose debris from the area to be cleaned.

2.  Never attempt to clean surface with objects that protrude from the surface being 

cleaned. Striking any raised obstacle during operation will damage machine. If 

contact does occur and results in vibration when operating machine, STOP and 

replace spray bar.
