To install the Model H3258 to your pneumatic
device:
1. Disconnect the compressor system from the
power source!
2. Drain the air pressure out of the tank and lines
before connecting the Model H3258 to your air
line.
3. Mount the Model H3258 (in the upright position
shown in Figure 1) on a wall close to the area of
air tool operation, using the wall mount guide
holes. You can also connect it directly onto the
compressor shut off valve. Note—Place the
Model H3258 away from direct sun or hazardous
materials.

5. Connect the air line (A) to the line-IN
1
⁄4" NPT
threads (B) on the Model H3258 as shown in
Figure 2. Note—Use as short of an air line
as possible, with minimal bends, to maintain
an accurate working pressure.
6. Thread on a male connector (D) to the Line
“OUT” threads (C) followed by a quick cou-
pler (E) as shown in Figure 2.
7. The quick coupler will accept a hose
connector (F) that attaches to the air hose
(G) going to your tool.
8. Fill the oil cup to the designated fill level with
air tool oil.
9. When the set up is complete and the fittings
are secure, start your air compressor and let
the air pressure build to the operating level.
10. Check for air leaks along the line by using
soapy water. If there are leaks present, dis-
connect the line on both sides of the leak.
Reseal the leaking fittings with teflon tape
and reconnect the line.
If you need additional help with this procedure,
call our service department at: (570) 546-9663.
4. Connect a
1
⁄4" NPT air line (A), in Figure 2, to the
shut-off valve on your air compressor. Seal all
the fittings with teflon tape to prevent leaks and
product failure.
INSTALL THIS SYSTEM AS CLOSE TO THE AIR
TOOL AS POSSIBLE FOR BEST PERFORMANCE!
