Figure 2. Hydraulic Connections
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
adapter 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
ttings or black pipe ttings.
Use thread tape or pipe joint compound when installing
quick disconnect couplings to hose or tool ttings. Fol-
low the instructions furnished with the selected thread
sealant. DO NOT OVERTIGHTEN THE FITTINGS.
6. BATTERY
The supplied 12 Volt DC battery is a non-spillable, main-
tenance-free battery and is fully charged.
Make sure the battery cables are tight and charging cir-
cuit functions are operating properly.
Do not charge the battery with a standard auto-
motive battery charger. This type of charger pro-
duces a charging amperage higher than 2 amps.
Charging the battery at higher than 2 amps will
damage the battery.
