WARNING: Only use hydraulic torque wrenches in a<br />
coupled system. Never use a torque wrench with<br />
unconnected couplers. If the torque wrench becomes<br />
extremely overloaded, components can fail catastrophically causing<br />
severe personal injury.<br />
IMPORTANT: Hydraulic equipment must only be serviced<br />
by a qualifi ed hydraulic technician. For repair service,<br />
contact the Authorized ENERPAC Service Center in your<br />
area. To protect your warranty, use only ENERPAC oil.<br />
WARNING: Immediately replace worn or damaged parts<br />
by genuine ENERPAC parts. Standard grade parts will<br />
break causing personal injury and property damage.<br />
ENERPAC parts are designed to fi t properly and withstand high<br />
loads.<br />
WARNING: Do not use electric pumps in an explosive<br />
atmosphere. Adhere to all local and national electrical<br />
codes. A qualifi ed electrician must do installation and<br />
modifi cation.<br />
Center.<br />
WARNING: Keep hands clear of moving parts and<br />

4.0 INSTALLATION<br />
Install or position the pump to ensure that air fl ow around the<br />
motor and pump is unobstructed. Keep the motor clean to<br />
ensure maximum cooling during operation.<br />
4.1 Reservoir Breather Cap (See Figure 2)<br />
A shipping plug is installed in the breather port on the top of<br />
the reservoir. Before using the pump, replace the shipping plug<br />
(C) with the breather cap (A) and adapter fi tting (B). Note: The<br />
breather port is separate from the oil fi ll port. The oil fi ll port (D)<br />
uses an SAE #10 plug.<br />
