We  are  proud  to  offer  the  grizzly  Model 
h7668  spray  gun.  this  model  is  part 
of  a  growing  grizzly  family  of  fine  tools. 
When used according to the guidelines set 
forth in this manual, you can expect years 
of  trouble-free,  enjoyable  operation,  and 
proof of grizzly’s commitment to customer 
satisfaction.

the Model h7668 is designed to be used 
for  bigger  jobs  where  large  volumes  of 
material  are  needed  and  greater  painter 
mobility is required. the two quart capacity 
allows the painter to spray with one hand 
and carry the pressure cup with the other.

it  is  our  pleasure  to  provide  this  manual 
with  the  Model  h7668.  it  was  written 
to  encourage  safety  considerations  and 
guide  you  through  general  operating  pro-
cedures and maintenance.

graphs in this manual represent the Model 
h7668 as supplied when the manual was 
prepared. however, owing to grizzly’s pol-
icy  of  continuous  improvement,  changes 
may be made at any time with no obliga-
tion on the part of grizzly.
