OPERATION
QUICK DISCONNECT COUPLERS
H.T.M.A. approved quick disconnect couplings are installed
to hydraulic hoses so that the direction of oil ow is always
from the male to the female quick disconnect as shown in
gure 2. Quick disconnect couplings and hose ttings are
selected so that additional ttings such as reducer or adapt-
er ttings are not required.
If adapter ttings are used, they must be approved steel
hydraulic ttings meeting a minimum operating pressure
rating of 2500 psi/172 bar. Do not use galvanized pipe t-
tings or black pipe ttings.
Use thread tape or pipe joint compound when installing
quick disconnect couplings to hose or tool ttings. Follow
the instructions furnished with the selected thread sealant.
DO NOT OVERTIGHTEN THE FITTINGS.

NOTICE
If the engine runs out of gas or dies during operation
and the ignition switch is left in the ON or RUN
