Graco 258849 Manual De Usuario

NOTE: When spraying water-based materials, flush the 
sprayer thoroughly with water. 

1.

Engage trigger lock and put prime/relief valve UP to 
release pressure. 

2.

Use the Fine-Finish Optimizer cleaning tool to lightly 
push on inlet valve to make sure it moves up and 
down freely.

3.

Install material cup liner, fill with material, and 
thread onto sprayer.

4.

To prime pump, disengage trigger lock and trigger 
sprayer for 10 seconds. Then release trigger and 
put prime/relief valve DOWN to spray position.

5.

Reverse spray tip to UNCLOG position and spray 
into waste area for five seconds. Then rotate tip 
back to SPRAY position. NOTE: Failure to perform 
this operation could result in poor spray pattern.

NOTE: If sprayer fails to prime, follow Alternative 
Priming Method (page 19) and/or Inlet Valve 
Cleaning (page 20).

Use only water-based materials. Do not use materi-
als which state “FLAMMABLE” on the packaging. For 
more information about your material, request MSDS 
from distributor or retailer. 

Spraying certain materials may cause static 
build-up in the sprayer that can result in static 
shock to the user. If this occurs, first ensure the mate-
rial has a flash point greater than 100° F (38° C) and 
does not state that it is FLAMMABLE anywhere on the 
package. If still feeling a static shock, the material likely 
contains a non-mineral spirits fluid such as, but not lim-
ited to, xylene, toluene, or naphtha, which can build up 
static. Switch to an alternative material.

Keep spray area well-ventilated. Keep a good supply 
of fresh air moving through the area.
