•  Do not expose the tool to heat sources in excess of 

158°F [70°C] as this could cause irreversible damage 

to cable insulation and other electrical components, 

possibly leading to a fire. If tool becomes overheated, 

allow tool to cool or remove heat source.

•  The tool is designed for noncontinuous use. Allow 

sufficiently long pauses to let the oil to cool. Consult 

Enerpac if prolonged and/or uninterrupted use is 

required.

•  Do not service or clean the tool, or replace blades 

or guards, while the tool is operating and/or if tool is 

connected to AC power supply.

•  Keep electric tools out of the reach of children. Do 

not allow inexperienced users or users who have not 

read the instructions to operate them. Electric tools 

are dangerous in the hands of non-expert users.

•  In accordance with the standards indicated and 

followed by the manufacturer, the equipment 

components that also perform a safety function 

(insulators, guards, etc.) must not be repaired, but  

must instead be replaced with original spare parts.

1.4  Additional AC Electric Tool Safety Instructions

 

NOTICE:

  WARNING

Failure to observe and comply with 

the following precautions and instructions could 

result in death or serious personal injury.
1.4.1  Use and Care

•  Store the tool indoors. Keep in a secured area to 

prevent use by unauthorized personnel.

•  Do not clean the tool with a water spray or the like.
•  Do not operate the tool with a damaged cord or 

plug, or after the tool malfunctions or is dropped or 

damaged in any manner.

•  Return the tool to the nearest Enerpac authorized 

service center for examination, repair, or electrical or 

mechanical adjustment.

1.4.2  Disconnecting Power

•  Be sure that tool motor is off before removing plug 

from electrical outlet.

•  Do not unplug the tool by pulling on the cord. To 

unplug, grasp the plug, not the cord.

•  Remove plug from electrical outlet when the tool is 

not in use and before servicing or cleaning the tool.

  

DANGER

High voltage is present inside the tool 

even when tool motor is off. Before servicing the 

tool, be sure that the tool power cord is disconnected 

from the electrical outlet or other electrical power 

source.
1.4.3  Grounding Instructions

  

DANGER

Risk of electric shock! Connect the tool 

only to a properly grounded outlet.

The tool is double insulated and equipped with a 

polarized power plug.
The plug must be plugged into a polarized electrical 

outlet that is properly installed and wired in accordance 

with all local codes and ordinances.

•  Keep cutting tools clean and replace blades when 

they become dull. Suitably maintained cutting tools 

with sharp edges are less likely to jam and are easier 

to control.

  CAUTION

Failure to observe and comply with the 

following precautions and instructions could result 

in minor or moderate personal injury. Property 

damage could also occur.

•  To help ensure proper operation and best 

performance, use only Enerpac HF hydraulic oil. Use 

of any other oil may result in unsafe operation and/or 

damage to tool. The Enerpac product warranty may 

also be invalidated.

•  Keep hydraulic equipment away from flames and 

heat. Excessive heat will soften packings and seals, 

resulting in fluid leaks. Heat also weakens hose 

materials and packings.

•  Protect all hydraulic equipment from weld spatter.

1.3   Safety Precautions - AC Powered Electric Tools

 

NOTICE:

  WARNING

Failure to observe and comply with the 

following precautions and instructions could result 

in death or serious personal injury. Property damage 

could also occur.

•  Always be certain that tool is stopped and 

disconnected from AC power supply before 

 

performing any tool cleaning, maintenance or repair 

procedures.

•  Be certain that the cutter is disconnected from the 

AC power supply before reaching inside the cutting 

head to clear jams, or for any other reason.

•  Do not leave the tool unattended in the workplace 

when connected to the AC power supply. Take all 

reasonable precautions to avoid unauthorized use.

•  Take precautions so that the tool is not switched on 

accidentally. Be certain not to press the trigger when 

picking up the tool or when positioning it.

•  If it is not possible to unplug the cutter power cord 

from the AC power outlet, the power must be turned 

off and locked out at the AC power supply.

•  Always disconnect the tool from AC power before 

transporting it. If electric tools are transported while 

the operator’s finger is on the trigger and AC power 

is connected, accidents can occur.

•  Do not use the tool if it cannot be switched on and off 

using the trigger. Any tool that cannot be controlled 

with the trigger is dangerous and must be repaired.

•  Remove all wrenches and adjustment tools (if 

present) before switching on the tool. A wrench or 

adjustment tool attached to a rotating element of an 

electric tool can cause personal injury.

•  Make sure the cooling vents are unobstructed and 

that the cooling surfaces are clean in order to avoid 

dangerous overheating.
