remove the probe from the sand, hold the gun trigger
open, and let the hose air dry. Always be sure the sand
hose is dry before using.
Keep the sand covered to prevent the overspray from
wetting the sand.
Do not allow small pieces of the sand bag to fall into the
sand supply. A small paper piece could prevent the flow
of sand.
NOTE: To extend the life of the tungsten carbide sand
nozzle (3) rotate the nozzle 45
minutes of use.
Operation
Sand Saver Operation (Optional)
The spring--loaded collar on the Sand--Saver rotates to
give four different rates of sand injection. From setting
number 1, (maximum sand injection) to setting number 4,
(minimum sand injection).
By experimenting with the different settings on your
Sand--Saver during sandblasting you can determine
which setting is the most economical for the job. See the
table below for approximate sand usage per minute at
each setting.
