Operations

Assembly

STEP 1:

 Attach a 5/8” water supply 

hose to inlet connector. Minimum 
flow should be 6 or 10 gpm 
depending on model of machine.

STEP 4:

 Check engine and pump 

oil level by removing oil dipstick, 
making sure oil is on proper 
indicator marking. Use SAE 10W-
30 or 15W-40 engine detergent oil 
for engine and SAE 10W-40 non-
foaming oil for pumps.

STEP 2:

 Attach wand to spray gun 

using teflon tape on threads to 
prevent leakage. Attach swivel 
connector on high pressure hose to 
spray gun using teflon tape on 
threads. Engage safety latch to 
prevent triggering gun when 
inserting high pressure nozzle.

STEP 5:

 Fill fuel tank with Ultra 

Low Sulfur Diesel fuel. 

STEP 3:

 Attach high pressure hose 

to discharge nipple using quick 
coupler. Lock coupler securely into 
place by pulling back coupler collar 
and inserting it into discharge 
nipple, then pushing collar forward 
to lock in place.

STEP 6:

 Install proper battery 

making sure that the red cable is 
attached to the positive terminal. 
Use a 12V Group 24 battery.
