WARNING

DANGER

WARNING

This manual should be read and understood by all personnel who operate or

service this Hydraulic Knockout Set. Failure to understand how to safely

operate and service this unit could result in injury or death. This unit should

only be operated or serviced by qualified personnel.

NEVER use the Knockout Set or any of its components near

live circuits.
ALWAYS stand to the side of the ram when punching. This

will help avoid injury should there be a component failure.
The model 1521 Hand Pump is pre-set at the factory to operate

at pressures up to 8,000 PSI. Do NOT connect any pump to the

Current Tools model 1522 Ram that will exceed 8,000 PSI. Doing

so may cause component failure which may result in injury or

death. Only use a hand or foot operated pump with the model

1522 Ram. Never operate the ram with an electric pump.
Be sure to support the ram while punching. An unsupported

ram could fall causing injury.
Do NOT continue to operate pump after the ram completes

the punch. Doing so will damage the ram and could cause

component failure resulting in serious injury or death.
If the ram motion stops before the punching process

is completed, Do NOT continue to operate the pump.

Release the pump pressure and disassemble the set-up

and determine the cause before continuing.
Hydraulic tools create tremendous pressures and hydraulic oil

can easily puncture skin. If your skin is pierced by oil you must

seek medical attention immediately! NEVER touch the hydraulic

hose or fittings while the unit is under pressure.
ALWAYS thread the punch COMPLETELY onto the draw stud

( or adapter ) to avoid thread failure. If the punch tightens before

it is completely threaded onto the draw stud, disassemble the

set-up and determine the cause. Then reassemble the set-up.
ALWAYS release the hydraulic pressure before removing

any hoses or before servicing any component of the

hydraulic system.
ONLY replace the hoses and fittings with Current Tools

replacement parts.
NEVER attempt to exceed the punching capacity of this

knockout set. Doing so may cause component failure and

possibly serious injury or death.
