This is the safety alert symbol. It is used to alert you 
to potential personal injury hazards. Obey all safety

IMPORTANT: READ THESE INSTRUCTIONS BEFORE OPERATING

BEFORE USING THIS DEVICE, READ THIS MANUAL COMPLETELY AND THOROUGHLY, UNDERSTAND ITS OPERATING 
PROCEDURES, SAFETY WARNINGS AND MAINTENANCE REQUIREMENTS.

THE NATURE OF HAZARDOUS SITUATIONS

METHODS TO AVOID HAZARDOUS SITUATIONS

CONSEQUENCES OF NOT AVOIDING HAZARDOUS SITUATIONS

 

WARNING: Indicates a hazardous 
situation which, if not avoided, could 
result in death or serious injury.

WARNING

•  Read, study, understand and follow all instructions before operating this press.
•  Always wear safety goggles, users and bystanders.
•  Parts being pressed may splinter, shatter, or be ejected from the press at a dangerous rate of speed. Because there are a variety of press 

applications, it is the responsibility of the press owner to provide adequate guards, eye protection and protective clothing to the press operator.

•  Visual inspection of the press should be made before use, checking for signs of cracked welds, bent bed pins, loose or missing bolts, leaks, or any 

other structural damage. Corrections must be made before using the press.

•  Do not go near leaks. High pressure hydraulic fluid can puncture skin and cause serious injury, gangrene, or death. If injured, seek emergency 

medical help as immediate surgery is required to remove the fluid.

•  Prior to use make sure the press is securely anchored to a concrete floor.
•  Keep hands, arms, feet, and legs out of work area. Accidental slippage can result in personal injury.
•  Always use an accurate force gauge to measure pressing force.
•  Do not exceed the rated capacity or tamper with the pressure/force settings. When attachments and adapters are used the rated capacity of the 

system shall be no greater than the rated capacity of the lowest rated component or combination of components that make up the system. 

•  Avoid off-center loads. Offset loads can damage ram and may cause load to eject at a dangerous rate of speed. Do not use any spacer or extender 

between the press ram plunger and the item being pressed. If there is not enough ram stroke, adjust the height of the movable bolster.

•  Remove all loads from movable bolster before attempting to adjust bolster height. Beware of possible falling bolster.
•  Press only on loads supported by movable bolster and press plates included. Do not support loads on floor or press frame legs.
•  When using any accessories such as press plates or arbor plates, be certain they are centered on the movable bolster and in full contact with both 

sides of the bolster.

•  Before applying load, be certain all movable bolster supporting pins are fully engaged. Verify lift cables (if equipped) are slack before pressing on 

the bolster.

•  Always use a bearing shield when pressing bearings.
•  Use caution when positioning work to be pressed to ensure the item to be pressed cannot be ejected at a dangerous rate of speed.
•  Release hydraulic pressure before loosening any fittings.
•  Maintain proper hydraulic fluid levels.
•  Do not make any alterations to the press.
•  Failure to heed and understand these markings may result in serious or fatal personal injury and/or property damage.

It is the responsibility of the owner to make sure all personnel read this manual prior to using the device. It is also the responsibility of the device 
owner to keep this manual intact and in a convenient location for all to see and read. If the manual or product labels are lost or not legible, contact 
Sunex for replacements. If the operator is not fluent in English, the product and safety instructions shall be read to and discussed with the operator 
in the operator's native language by the purchaser/owner or his designee, making sure that the operator comprehends its contents.    

Failure to read this manual completely and thoroughly, failure to understand its OPERATING INSTRUCTIONS, SAFETY WARNINGS, MAINTENANCE 
INSTRUCTIONS and comply with them, and failure to compy with the METHODS TO AVOID HAZARDOUS SITUATIONS could cause accidents 
resulting in serious or fatal personal injury and/or property damage.

The use of shop presses and their accessories is subject to certain hazards that cannot be prevented by mechanical means, but only by the 
exercise of intelligence, care, and common sense. It is therefore essential to have owners and personnel involved in the use and operation of the 
equipment who are careful, competent, trained, and qualified in the safe operation of the equipment and its proper use. Examples of hazards are 
components being pressed and breaking resulting in flying parts that are not secured from hitting the operator, the set up in the press is not secure, 
guards, shields or protective blankets are not used, improperly securing adjustments on the press, overloading and off-center loads.

This product can expose you to chemicals including nickel which is known to the State of California to cause cancer and birth defects or 

other reproductive harm.  For more information go to www.P65Warnings.ca.gov.
