IMPORTANT SAFETY
INSTRUCTIONS
INSTRUCTIONS PERTAINING TO A
RISK OF INJURY TO PERSONS
WARNING – When using shop equipment,
basic precautions should always be
followed, including the following:
Work area
Do not install this Shop Press on any a.
asphalt or wood surface. Make sure
the Press is rmly secured to a dry,
oil/grease free, at, level, concrete
surface capable of supporting the
weight of the Press, the workpiece
being pressed, and any additional
tools and equipment. Do not install
the Press on expansion seams or on
cracked, defective concrete.
Keep the work area clean and well b.
lighted. Cluttered benches and dark
areas increase the risks of injury to
persons.
CAUTION, used
with the safety
alert symbol, indicates a
hazardous situation which, if
not avoided, could result in
minor or moderate injury.
SKU 65330 For technical questions, please call 1-800-444-3353. Page 2
Do not operate the Shop Press in ex-c.
plosive atmospheres, such as in the
presence of ammable liquids, gases,
or dust. The Press is able to create
sparks resulting in the ignition of the
dust or fumes.
Keep bystanders, children, and visi-d.
tors away while operating the Shop
Press. Distractions are able to result
in the loss of control of the tool.
Personal safety
Never exceed the recommended a. 110
to 120 PSI working pressure and 20
ton pressing capacity for this Shop
Press. This Press will do the job better and safer at the PSI and pressing
capacity for which it was designed.
Never leave a compressed workpiece g.
unattended. Whenever a workpiece
is compressed, there is a very large
amount of force that has been stored
in the workpiece which must be controlled until the Press Head or Filter
Crushing Head is relaxed.
Always release a load from the Shop h.
Press, and disconnect the unit from
its air supply source before performing any services or maintenance on
the unit.
Make sure to read and understand all b.
instructions and safety precautions as
outlined in the manufacturer’s service
manual for the workpiece you are
pressing. Always use the manufacturer’s recommended pressing points,
minimum/maximum pressing force
required, etc., for the workpiece you
are pressing.
Prior to using the Shop Press, make c.
sure tool trays, stands, and all other
tools and equipment are removed
from the Working Bed.
Always keep your hands and ngers d.
safety away from the Press Head
and Filter Crushing Head during the
pressing process.
Never attempt to remove a workpiece e.
stuck in the moving parts of the Shop
Press while it is connected to its air
supply source.
Once contact between the Press f.
Head or Filter Crushing Head and the
workpiece has been made, step away
as far as possible and continue to
slowly apply pressure until the procedure is completed.
Stay alert. Watch what you are doing i.
and use common sense when operating the Shop Press. Do not use the
Press while tired or under the inuence of drugs, alcohol, or medication.
A moment of inattention while operating the Press increases the risk of
injury to persons.
Dress properly. Do not wear loose j.
clothing or jewelry. Contain long hair.
Keep hair, clothing, and gloves away
from moving parts. Loose clothes,
jewelry, or long hair increases the risk
of injury to persons as a result of being caught in moving parts.
Avoid unintentional starting. Be sure k.
the Lever on the Valve Body of the
Air/Hydraulic Jack is off before connecting to the air supply.
Remove adjusting keys and wrench-l.
es before connecting to the air supply. A wrench or a key that is left
attached to a moving part of the Shop
Press increases the risk of personal
injury.
Do not overreach. Keep proper foot-m.
ing and balance at all times. Proper
footing and balance enables better

control of the tool in unexpected situations.
n. Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable
conditions. Wear heavy-duty work
gloves during use.
o. Always wear eye protec-
tion. Wear ANSI-approved
safety goggles.
p. Always wear hearing
protection when using the
Shop Press. Prolonged
exposure to high intensity
noise is able to cause hearing loss.
Use clamps or another practical way c.
to secure and support the workpiece
to Arbor Plates and Press Apron.
Holding the work by hand or against
the body is unstable and is able to
lead to loss of control.
Do not force the Shop Press.d. Use the
correct equipment for the application.
The correct equipment will do the job
better and safer at the rate for which
the equipment is designed.
Do not use the Shop Press if the Le-e.
ver on the Valve Body of the Air/Hydraulic Jack does not turn the Press
on or off. Any equipment that cannot
be controlled is dangerous and must
be repaired.
WARNING!q. The brass components
of this product contain lead, a chemical known to the State of California
to cause birth defects (or other reproductive harm). California Health &
Safety Code 25249.5, et seq.)
Tool use and care
WARNING! If you detect anything a.
that may indicate imminent structural
failure to the Shop Press, discontinue
using the Press immediately. Disconnect the Press from its air supply
source, and have the Press repaired
before further use.
Avoid off-center loads. If the Ram b.
seems unusually hard to press, immediately stop the operation. Disconnect the Shop Press from its
air supply source, and adjust the
workpiece to eliminate or diminish an
off-center load. Do not operate the
Press if the workpiece tilts or binds
during the down movement of the
Ram.
Disconnect the Shop Press from the f.
air source before making any adjustments, changing accessories, or storing the Press. Such preventive safety
measures reduce the risk of starting
the Press unintentionally. Turn off
and detach the air supply, safely discharge any residual air pressure, and
release the Lever on the Valve Body
of the Air/Hydraulic Jack before leaving the work area.
Keep the Air/Hydraulic Jack properly g.
lled with hydraulic oil. For instructions, refer to the Air/Hydraulic Jack
owner’s manual (included).
Keep the Shop Press out of reach of h.
children and other untrained persons.
A Shop Press is dangerous in the
hands of untrained users.
Maintain the Shop Press with care. A i.
properly maintained Shop Press reduces the risk of binding and is easier
to control.
SKU 65330 For technical questions, please call 1-800-444-3353. Page 4
Check for misalignment or binding of j.
moving parts, breakage of parts, and
any other condition that affects the
Shop Press’ operation. If damaged,
have the Press serviced before using.
Many accidents are caused by poorly
maintained equipment. There is a risk
of bursting if the equipment is damaged.
Use only accessories that are iden-k.
tied by the manufacturer for the
specic Shop Press model. Use of an
accessory not intended for use with
the specic model increases the risk
of injury to persons.
Air source
a. Never connect to an air
source that is capable of
exceeding 120 PSI. Over
pressurizing the tool may
cause bursting, abnormal operation,
breakage of the tool or serious injury
to persons. Use only clean, dry,
regulated compressed air at the rated
pressure or within the rated pressure
range as marked on the tool. Always
verify prior to using the tool that the
air source has been adjusted to the
rated air pressure or within the rated
air-pressure range.
Only use with accessories rated to l.
handle the forces exerted by this
Shop Press during operation. Other
accessories not designed for the
forces generated may break and
forcefully launch pieces.
Attach all accessories properly to the m.
Shop Press before connecting the
air supply. A loose accessory may
detach or break during operation.
Install an in-line shutoff valve to allow n.
immediate control over the air supply
in an emergency, even if a hose is
ruptured.
Service
Equipment service must be per-a.
formed only by qualied repair personnel.
When servicing the Shop Press, use b.
only identical replacement parts. Use
only authorized parts.
Use only the lubricants supplied with c.
the Shop Press or specied by the
manufacturer.
Never use oxygen, carbon dioxide, b.
combustible gases or any bottled gas
as an air source for the tool. Such
gases are capable of explosion and
serious injury to persons.
