make certain the gaskets inside the brass end nuts
seal the glass tube. Use caution not to break the
glass tube. After tightening the fittings, apply 3−4
drops of ‘Loctite Threadlocker No. 242’ or equiva-
lent compound to each threaded joint. The thread-
locker will leach" into the threads to prevent loos-
ening of the sight glass tube. Install the male adap-
tor and close nipple in the ends of the sight gauge.
NOTE
When tightening the sight tube adaptor and close
nipple, hold the hex fittings on either end of the
sight tube assembly with an open ended wrench to
prevent the end fittings of the sight tube assembly
from tightening and breaking the sight gauge.
Slide the sight tube assembly up through the
grommet (14) with the male adaptor fitting toward
the swivel (12). Screw the sight tube assembly into
the swivel, then reinstall the elbow (22).
See Hose Reassembly when connecting the
hose to the reel.
Hose Reassembly
(Figure 5)
Clean the nozzle parts in fresh cleaning solvent.
Most cleaning solvents are toxic and
flammable. Use them only in a well ven-
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain-
ers.
Insert the hose nozzle (8) into the end of the hose
assembly so the hole in the metal tape inside the
hose aligns with the hole in the nozzle and secure it
with the roll pin (5).
Install the nozzle guard (9) over the nozzle and se-
cure with the machine screws (10).
Assemble the roller (12) in the nozzle guard and
install with the roller pin (11). Peen the end of the
pin to retain the roller.
Connect the other end of the hose assembly to the
reel assembly. Reach through the access hole in
the reel discs with two open end wrenches and
tighten the fittings.
NOTE
The reel end of the hose assembly must be posi-
tioned so the word TOP" on the hose fitting is vis-
ible when looking down at the fitting between the
reel discs.
Coil the hose into the reel assembly and and check
the position of the hose nozzle. The nozzle must be
positioned as shown in Figure 4 with the roller
away from the center of the reel.
