Additional Safety for Hydraulic Presses
1.
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, safety glasses with a face
shield. Heavy leather boots with extra toe
protection are also required. Under certain
conditions, a hard hat may be needed.
2.CORRECT INSTALLATION. An unsecured press on wheels can tip when being
moved or exhibit severe spring-back during 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 floor.
3.
4.
PRE USE Inspections. A loosely
assembled press 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.
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.
5.UNSAFE WORKPIECE. Applying pressure to unstable objects can eject the
object, causing an impact injury. Never
apply pressure to balls, round objects,
springs, or elastic items.
-6-
6.
AVOIDING PROJECTILE INJURIES.
Being hit with a ejected 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 cock off-center and kick
out under a load. Never stack rods and
spacers to create an extended press-pin. If
pressing must occur with extended presspins, 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.
7.CORRECT TOOLING. Without using the
correct spring caging tool or jig to hold the
a spring-loaded workpiece, the workpiece
may shift suddenly, ejecting springs and
causing a severe impact injury. Never use
this press to unload spring-loaded assemblies without also using the correct spring
caging tool or jig.
8.CORRECTING MISALIGNED LOADS. If
a workpiece becomes misaligned during
pressing operations, it may slip out of the
press and cause a 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.
9.
SAFE WORKING ZONE. Tooling or arbor
plates that shift and fall from the press can
cause a crushing injury to your leg or foot.
Keep out from under the bed, do not work
under the press when it is loaded, and
never leave the press loaded and unattended.
Model H6228Z (Mfg. since 1/10)
10.AVOIDING
INCORRECT
PRESS
OPERATIONS. Some workpieces cannot
withstand the force of pressing and can
explode, causing an impact injury. Other
workpieces have hidden retaining rings,
shoulders, pins, welds, or are integral and
cannot be pressed apart. Before using this
press, make sure that you understand how
a component is built and pressed apart.
11. SAFE HYDRAULIC REPAIR. Repair that
is performed by an unqualified person can
lead to press overload or a hydraulic line
burst, causing hydraulic oil being injected into your blood stream causing blood
poisoning. Do not attempt to repair the
hydraulic system unless you are a qualified
hydraulic service professional.
12.UNAUTHORIZED
MODIFICATION.
Modifying the press frame, increasing pump
relief pressure, or installing a higher capacity jack or hydraulic system can cause
structural failure, and lead to a severe
crushing injury. If the press is insufficient
for your pressing task, use a press that is
rated for the correct load capacity.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety precautions are overlooked or ignored, serious
personal injury may occur.
Model H6228Z (Mfg. since 1/10)
13. AVOIDING SPRING-BACK HAZARDS.
Under heavy pressing operations, when
some parts finally break free of the host
workpiece, sudden hydraulic press unloading can occur in the form of spring-back.
As a result a workpiece, press pin, or an
arbor plate can spring up and fall from
the bed, causing a crushing injury to your
foot or leg. Before press operations begin,
anticipate what the workpiece may do if
this sudden unloading occurs, and secure
the workpiece so it will not fall.
14.AVOIDING OVERLOAD. Using a cheater
pipe for increased leverage or exceeding
rated press capacity can damage the press,
shatter a workpiece, or launch a press pin,
causing a severe impact injury. Do not
exceed the rated capacity of this press.
When the press has reached its maximum
pressure or the pump lever becomes stiff
to operate, the press has reached its limit
and the jack lever must not be pumped any
further.
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious personal injury, damage to equipment, or poor
work results.

Site Considerations
Physical Environment
Weight Load
The physical environment where your machine
is operated is important for safe operation and
the longevity of its components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.
Refer to the Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
Lighting
Lighting around the machine must be adequate
enough that operations can be performed safely.
Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the maintenance and service described in this manual.
See below for required space allocation.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.

Mounting to Shop
Floor
Under heavy pressing operations, the entire press
structure is under great tension and compression,
when the item to be pressed off the workpiece
breaks free, the load on the workpiece is suddenly relieved. The entire machine and workpiece
spring-back to the normal unloaded condition. At
times this can be loud and startling. As a result
the workpiece, heavy arbor plates, or the presspin may fall or be ejected from the press causing
injury.
To eliminate a tipping hazard and increase the
structural rigidity of the press, you must mount the
press to a concrete floor that is at least 4" thick.
Do not mount the press to a mobile base or install
casters or you will create a tipping and springback hazard.
Bolting to Concrete Floors
Since floor materials vary, mounting hardware is
not included with your machine; however, lag shield
anchors with lag bolts and anchor studs as shown
in Figure 16 are two popular methods for anchoring machines to a concrete floor. We suggest
you research the many options and methods for
mounting your machine and choose the best that
fits your specific application. Remember, always
wear safety goggles and a NIOSH approved dust
mask when drilling into concrete.

SECTION 3: OPERATIONS
Operation Overview
To reduce the risk of
serious injury when using
this machine, read and
understand this entire
manual before beginning
any operations.
This overview describes you the basic process that
happens during an operation with this machine.
Familiarize yourself with this process to better
understand the remainder of this section.
To complete a typical press operation, the
operator does the following:
Damage to your eyes, fingers, or feet could
result from using this machine without proper protective gear. Always wear safety glasses, face shield, leather gloves, and leather
boots that have extra toe protection.
1.Puts on the required personal safety equipment, and clears away all bystanders.
2.Reviews workpiece inspection items, and
prepares the workpiece to make it suitable for
press operations.
3.Retracts the hydraulic ram completely, and
positions the bed so there is the shortest distance between the ram and workpiece.
4.
NOTICE
If you have never used this type of machine
or equipment before, We strongly recommend that you read books, review
industry trade magazines, or get formal
training before beginning any projects.
Regardless of the content in this section,
Grizzly Industrial will not be held liable for
accidents caused by lack of training.
Model H6228Z (Mfg. since 1/10)
Verifies that both bed support pins are
installed correctly, and fully supporting the
bed.
5.Places a catch basket under the press with
the applicable padding to protect the part
when it drops.
6.Positions the arbor plates to support the
workpiece and aligns the press-pin or tooling
on the part to be pressed.
7.Lowers the press ram to slightly preload the
workpiece.
8.

Controls
Review the list and Figure 17 below to familiarize
yourself with the hydraulic controls.
A. Hydraulic Bottle Jack. Houses the control
valve, relief valve, hydraulic fluid, and the
pump system, which create the hydraulic
force required for press operations.
B. Pump Lever. Gives the press operator the
leverage to operate the bottle jack pump and
the press. The lever is also used to open and
close the jack control valve.
Workpiece
Inspection
Before using this hydraulic press, you must
inspect the workpiece. This is not a comprehensive list, but rather a list of common oversights.
It is up to you to address any additional special items required to prepare your workpiece
for press operations. Not making the minimum
inspections below can lead to galled, seized, or
broken housings. In some situations, ignoring just
one of the listed items can lead to a workpiece or
tooling being ejected from the press, which could
cause severe injury or death.
C. Hydraulic Pump. Creates the pressure for
the press operations.
•
D. Pressure Relief Valve. This valve is factory
set at safe levels and should not be re-adjusted.
Workpiece Strength: Make sure that the
workpiece material is designed to withstand
the intended force the press will apply.
•
Workpiece Cleanliness: Make sure that the
workpiece is clean and that all burrs, grit,
rust, or damage is removed from the pressing
path. Often light oiling on the components is
beneficial to prevent galling or seizing.
•
Pressing Path: Make sure that the direction
of component to be pressed on or off is correct, and that the correct size of sleeve or
arbor plate is used for support.
•
Retaining Mechanisms: Make sure that
all retaining rings, pins, or fasteners are
removed, and no hidden secondary retainers
are present.
•
Hidden Projectiles: Some components
house one or more springs. Make sure that
the part to be dismantled with the press has
the applicable caging system to catch the
springs should the workpiece slip or open up
when the retaining ring is removed and the
hydraulic pressure is relieved.
•
Special Fits: Make sure that the interference fits are correct before pressing a part
on, and make sure that the applicable parts
have been heated or chilled to the correct
temperatures to avoid galling and seizing.
Recognize that not all parts were designed to
be pressed off, we do not advise attempting
to press these types of parts off.
E.
Press Ram. Point at which the press applies
force to the workpiece or press-pin.
F.Control Valve. When rotated clockwise to the
closed position, the pump and jack can perform press operations. When rotated counterclockwise to the open position, applied
pressure is relieved and the press and jack
retract to the unloaded position.
G. Return Spring. Each spring retracts and
supports the press ram assembly to the
uppermost unloaded position when the control valve is opened.

SECTION 5: MAINTENANCE
Lubrication
Always relieve hydraulic pressure before
performing maintenance. Failure to do this
may result in serious personal injury.
Schedule
To lubricate the jack:
1.
Using a hand-held oil gun, apply one or two
drops of any standard machine oil or motor oil
to all clevis pins, as shown in Figure 22.
For optimum performance from your machine, follow this maintenance schedule, and refer to any
specific instructions given in this section.
Daily Check:
•Inspect for loose mounting bolts.
•
Inspect for damaged or leaking hydraulic
seals, fittings, or lines.
•
Inspect for frame cracks.
•
Inspect for any other unsafe condition.

2.
With the press completely retracted in the
uppermost position, remove the rubber plug
(Figure 22), and fill the bottle jack reservoir
with any standard hydraulic oil until oil runs
from the port. Reinstall the plug.
3.
Use the valve control socket at the end of
the pump handle to close the control valve,
then pump the jack a few times to bleed the
hydraulic system.
Cleaning
Cleaning the Model H6228Z is relatively easy.
Vacuum excess metal chips or contaminants
away from hydraulic seals and pivot pins. Wipe off
the remaining dust with a dry or lightly oiled cloth.
Treat all unpainted cast iron and steel with a nonstaining lubricant after cleaning.
Unpainted Cast Iron
Protect the unpainted metal surfaces on the bed
and arbor plates by wiping them clean after every
use.
