additional Safety for Hydraulic Presses
1. avOiDiNg OvERLOaD. Exceeding rated
press capacity can damage the press,
shatter a workpiece, or launch a press pin
causing a severe impact injury. When the
press has reached its maximum pressure
or the pump lever becomes stiff to oper-
ate, the press has reached its limit. never
use a cheater pipe for extra leverage.

causing a severe impact injury. When the
press has reached its maximum pressure
or the pump lever becomes stiff to oper-
ate, the press has reached its limit. never
use a cheater pipe for extra leverage.
2. OPERaTiON SafETy. Applying pressure
to parts with this press can cause them to
spring out and strike you or bystanders
with deadly force. Verify that bystanders
are a safe distance away from the press
during operations. make sure that you are
wearing gloves and safety glasses with
a face shield. heavy leather boots with
extra toe protection are also required.
Under some conditions, a hard hat may
be needed.

3. CORRECT iNSTaLLaTiON. An unse-
cured press on wheels can tip when being
moved or exhibit severe spring-back dur-
ing heavy pressing operations, which
could cause a crushing or impact injury.
do not place the press on a mobile base
or install casters. the press base must be
bolted to the workbench.

do not place the press on a mobile base

4. PRE-uSE iNSPECTiONS. A loose press
frame can cock under a load and cause
the workpiece to shift or eject, resulting in
an impact injury. Before use, inspect the
press for loose or missing bolts and pins.
Verify that no cracks exist and that the
hydraulic system is in full working order.

5. WORKPiECE SuPPORT. When a part
is pressed free, a workpiece may shift
suddenly or fall from the press, causing a
crushing injury to your foot or leg.

Use a
catch basket and support long or awkward
workpieces with stands or chains, or have
an assistant support the end of a long
workpiece during pressing operations.

6. uNSafE WORKPiECE. Applying pressure
to unstable objects can cause the object to
eject, causing an impact injury. never apply
pressure to balls, round objects, springs, or
elastic items.

pressure to balls, round objects, springs, or
elastic items.
7. avOiDiNg PROJECTiLE iNJuRiES.
Being hit by a launched workpiece or press
tooling can cause severe impact injury or
death. When using the press, stand out
of the way of any possible projectile path.
never press with rods or pins that are long
enough to shift off-center and kick out
under a load. never stack rods and spacers
to create an extended press pin. if pressing
must occur with an extended press pin, the
pin must be fastened with a safety chain or
the press pin must be enclosed in a safety
cage to eliminate a projectile hazard.

8. CORRECT TOOLiNg. Without using the
correct spring caging tool or jig to hold the
spring-loaded workpiece, the workpiece
may shift suddenly, launching springs that
could cause a severe impact injury. never
use this press to unload spring-loaded
assemblies without also using the correct
spring caging tool or jig.

9. CORRECTiNg MiSaLigNED LOaDS. if
a workpiece becomes misaligned during
pressing operations, it may slip out of the
press and cause severe impact injury.
never attempt to realign a workpiece while
it is under pressure. relieve hydraulic
pressure, and start pressing operations
over if a workpiece or press pin has moved
or become misaligned. relieve hydraulic
pressure if you suspect the workpiece is in
a bind, or structural failure is imminent.
