7. Remove the five colored quick-connect nozzles from
the plastic bag and insert them into correct grommet
on the nozzle holder. Nozzles are color coded to
match colored nozzles on panel assembly.
NOTE: The high pressure pump is maintenance free
and requires no oil, if there is a problem with the pump
contact a D
WALT factory service center, a D

vice center or other qualified service personnel.
WARNING: Risk of bursting. Use a tire pressure gauge to check the
tires pressure before each use and while inflating tires; see the tire side-
wall for the correct tire pressure.
NOTE: Air tanks, compressors and similar equipment used to inflate
tires can fill small tires similar to these very rapidly. Adjust pressure
regulator on air supply to no more than the rating of the tire pressure.
Add air in small increments and frequently use the tire gauge to
prevent over inflation.
OPERATION
Pressure Adjustments
The pressure setting is preset at the factory to achieve op ti mum pres-
sure and cleaning. To lower the pres sure, follow these instructions.
1. Back away from the sur face to be cleaned. The further away you
are, the less the pressure will be on the surface to be cleaned.
2. Change to the 40˚ nozzle (white). This nozzle delivers a less
powerful stream of water and a wider spray pattern. Refer to
Spray Wand Nozzles.
CAUTION: DO NOT attempt to increase pump pressure. A higher
pressure setting than the factory set pressure may damage pump.
3. Reduce the speed of the gasoline engine (RPM). Slow the
engine down and the water pressure will go down with it.
Spray Wand Nozzles (Fig. 1)
The nozzles for the spray wand are stored in the nozzle holder (G) on
the panel assembly (F). Colors on the panel identify nozzle location
and spray pattern. Refer to the following chart to choose the correct
nozzle for the job to be performed.
