When connect the pipe to the unit or b
wrench. As shown in
Fig.21.
When connect, smear both inside and outside of the flare nut with freeze motor oil, screw it by hand
☆
and then tighten it with spanner.
Refer to
Table 4 to check if the wrench had been tightened (too tight would mangle the nut and lead
