We've done all we can to assure this press offers the outmost in safety, but you have to do your part. No
amount of warning can take the place of your good judgment, so make sure it's the first thing you bring to
any job. Beyond that here are some obvious tips:
• Steel and others materials can shatter, so always use protective eye-wear that complies with the
appropriate ANSI code.
• If you detect anything that may indicate imminent structural failure, stop using the press immediately
and inspect it thoroughly.
• Bolt the press to the floor if it is to be used on bulky or unstable items.
• Do not use press to compress springs or any other item that could disengage and cause a potential
hazard.
• Use a qualified person to maintain the press in good condition. Keep it clean for best and safest
performance.
• Do not exceed the rated capacity. Never apply excessive force to a workpiece and always use the
pressure gauge to accurately determine the applied load.
• Use this press for the purpose for which it is intended. DO NOT use it for any other purpose it is not
designed to perform.
• Keep children and unauthorized persons away from the work area.
• Remove ill fitting clothing. Remove ties, watches, rings and other loose jewelry and contain long hair.
• Wear ANSI approved impact safety goggles, full-face impact safety shield and heavy-duty work gloves
when operating the press.
• Keep proper balance and footing, do not over-reach and wear nonskid footwear.
• Only use this press on a surface that is stable, level, dry and not slippery, and capable of sustaining the
load. Keep the surface clean, tidy and free form unrelated materials and ensure that there is adequate
lighting.
• Inspect the press before each use. DO NOT use if bent, broken, cracked, leaking or otherwise damaged.
• Check to ensure that all applicable bolts and nuts are firmly tightened.
• Ensure that workpiece is center-loaded and secure.
• Keep hands and feet away from bed area at all times.
• Never stand directly in front of loaded press and never leave loaded press unattended.
• DO NOT operate the press when you are tired or under the influence of alcohol, drugs or any
intoxicating medication.
• DO NOT allow untrained persons to operate the press.
• DO NOT make any modifications to the press.
• DO NOT use brake fluid or any other improper fluid and avoid mixing different types of oil when adding
hydraulic oil. Only good quality hydraulic oil can be used.
• DO NOT expose the press to rain or any other kind of bad weather.
• If the press needs repairing and/or there are any parts that need to be replaced, have it repaired by
authorized technicians and only use the replacement parts supplied by the manufacturer.
WARNING! The warnings, cautions and instructions discussed in this manual cannot cover all conditions
and situations that may occur. It must be understood by the operator that common sense and caution are
factors which cannot be built into this product, but must be supplied by the operator.

BEFORE FIRST USE
a) Before first use of this product, purge away air from the hydraulic system: open the release valve by
turning it counterclockwise. Pump several full strokes to eliminate any air in the system.
b) Check all parts and conditions, if there is any part broken, stop using it and contact your supplier
immediately.
c) If under plate (29) is not in the centre, loose the screw (23) slightly, then slide the under plate to the
position you need and tighten the screw.
OPERATIONG INSTRUCTIONS
WARNING! ENSURE THAT YOU READ, UNDERSTAND AND APPLY THE SAFETY INSTRUCTIONS AND WARNINGS
BEFORE USE.
• Place the heel block on bed frame, then insert workpiece onto the heel block.
• Connect the air inlet fitting into the shop air supply hose lock fitting, turn on the air valve (pistol) to let
the pump work until the ram nears to the workpiece, then turn off the air valve (pistol) When air source
is unavaliable, use the handle to pump.
• Align workpiece and ram to ensure center-loading.
• Turn on air valve (pistol) (or pump the handle) to apply load onto workpiece.
• When work is done, turn off the air valve (pistol) (or stop pumping handle), slowly and carefully remove
loadfrom workpiece by turning the release valve conterclockwise in small increments.
• Once ram has fully retracted, remove workpiece from bed frame.
• Disconnect the air inlet fitting from the air source.
MAINTENANCE
• Clean the outside of the press with dry, clean and soft cloth and periodically lubricate the joints and all
moving parts with a light oil as needed.
• When not in use, store the press in a dry location with ram and piston fully retracted.
• When press efficiency drops, purge always air from hydraulic system as described before.
• Check the hydraulic oil; remove the oil filler nut on the top of the reservoir, if the oil is not adequate, fill
with high quality hydraulic jack oil as necessary, then replace the oil filler nut, purge away air from the
hydraulic system.
