3. Be sure electrical power source is the correct one for
your pump. (See “3.0 Specifications” for electrical power
source specification).
4. Loosen lock nut and back out (turn counter-clockwise)
relief valve to prevent unintended pressure build-up. No
tools are needed to adjust relief valve. See Figure 1.
4.1 Hose Connections for Single-Acting
1. Couple hose to pump outlet shown in Figure 2. BE
SURE to use hose marked “ENERPAC 800 SERIES -
800 BAR/11,600 PSI MAX”.
2. Connect other end of hose to coupler on wrench as
shown in Figure 4.
4.2 Hose Connections for Double-Acting
1. Couple hoses to pump outlet manifold shown in Figure
3. BE SURE to use hose marked “ENERPAC 800
SERIES - 800 BAR/11,600 PSI MAX”.
“A” port is for advancing and “B” port is for retracting
the piston in the torque wrench. Pumps are supplied
with the specified coupling halves already connected to
the pump ports to prevent incorrect coupling of hoses
to wrench.
2. Couple hoses to torque wrench as shown in Figure 4.
When using the Enerpac pump and torque wrench
combination, Series 800 hoses and couplers are
designed so that the pump advance port can only be
connected to the wrench advance port, and the pump
retract port can only be connected to the wrench
retract port.
5.0 OPERATION
When possible, a single user should operate the torque
wrench and pump. This can prevent accidental activation of
the pump while the operator is positioning the wrench.
1. Check all system fittings and connections to be sure
they are tight and leak free.
