SAFEGUARDING THE POINT OF OPERATION
ANSI B11.2 - Hydraulic Power Presses -
Safety Requirements for Construction, Care, and Use
It is important that Dake press users have a clear understanding of their responsibility involving the care
and use of their Dake hydraulic press, including point-of-operation safe guards. Dake strongly
recommends that Dake press users obtain a copy of the current American National Standard Institute
(ANSI) B11.2 standard, for a more complete understanding of their responsibilities.
ANSI B11.2 states the following, relative to point of operation safeguarding:
“Normally, only the employer (press user) can determine the requirements of the press productions
system components, including the dies and methods for feeding. Therefore, the employer is ultimately
responsible to designate and provide the point-of-operation safeguarding system.”
The standard also discusses additional responsibilities of the employer. Some of the key responsibilities
are:
•The employer is responsible for the safety, use, and care of the hydraulic power press production
system.
•The employer is responsible to consider the sources of hazards for all tasks to be implemented on
the hydraulic power press production system.
•The employer is required to eliminate, or control identified hazards in the scope of their work activity.
•The employer is responsible for the training of personnel, caring for, inspecting, maintaining, and
operating hydraulic press production systems to ensure their competence.
•The employer is responsible to provide and ensure that point-of-operation safeguarding is used,
checked, maintained, and where applicable, adjusted on every production operation performed on a
press production system.
A complete and current copy of the ANSI B.11.2 standard can be obtained by contacting the following:

SET UP
For shipping convenience some of the parts are not assembled. Assemble these parts in the
following order:
1. Bolt the base angles to uprights using four provided bolts and nuts. Ensure that the base
angles are against the stops on the uprights. The press should set on a level floor with
base angles touching the floor at all points, use shims when necessary.
2. Connect airline in to street elbow (Item 136) at the right side of the control block. Avoid
restrictions in air supply line to ensure ampler air to the air motor. For maximum
performance the air supply line should be 1/2” pipe if the distance from the compressor to
the press is 0-30 feet, 3/4” line for 30-60 feet, and 1” if distance is greater then 60 feet.
WARNING: AIR MUST BE MOISTURE FREE. WATER IN THE AIR LINE COULD
CORRODE PRESS BEYOND REPAIR.
3. Oil Requirements: Fill the reservoir with Mobil DTE 24 or equivalent oil through the
pipeline in back of the press at pipe coupling by removing the pipe plug. Make sure the
air source is removed from the reservoir prior to removing the plug. Oil level may
be checked, with the ram up, by removing the pipe plug on the right side of the
reservoir near the front. Replace plug before operating the press.
Model 6-275 & 6-475, 75-ton presses use 10 quarts.
4. Attach nose piece to ram by inserting shank into ram and tightening the set screw.
5. Place the hoist crank on the lift drum shaft. Turn the hoist crank to relieve the pressure on
the table pins. Keeping tension on the hoist crank, remove the table pins one at a time.
a. After removing the table pins turn the crank running the table channels from top to
bottom. Check to make sure the cable is tracking correctly. The cable should be
on each of the two upper pulleys and should track back and forth on the cable
drum. Always place table pins under the table channels before releasing the hoist
crank when positioning the table channels for cable tracking, servicing, or set-up
for desired work opening.
b. If a tracking problem exists contact Dake for instructions. Be sure all table pins are
fully inserted in place before applying pressure. Always remove or release
pressure on the cable before pressure is applied.

OPERATION
WARNING DO NOT OVERSTROKE THE RAM. Over-stroking will cause premature seal
failure. Models 6-275, and 6-475 have a 10-inch stroke.
The press has been completely tested at the factory and after setting up according to this
manual the press is ready for operation. However it is necessary for the operator to acquaint
themselves with the controls.
1. Three screws (Item 109) are used to lock the workhead in desired position along the
head channels.
2. The handcrank is to raise and lower the work table channels to proper work height. When
desired height is obtained insert the table pins. Models 6-275, and 6-475 use 2 pins on
each side, 4 total. Be sure all table pins are in place and in as far as they can go
before pressure is applied. Be sure to slack off the cable before pressure is
applied. See step 5 of the “SET UP” in this manual.
3. The handle on the left side of the control block (Item 76) opens and closes the ball valve
which releases the ram pressure. This valve should be kept firmly closed and opened
only when it is desired to return the ram to its up position.
4. The two table plates and two V-blocks are used for supporting the work in process.
5. The control knob (Item 103) on the right side of the panel regulates the speed of ram
travel. The knob will return to the off position when released.
6. The relief valve (Item 90) had been set at factory to open at maximum tonnage of the
press. The valve can be adjusted by removing the hex nut located on the top of the valve
block at the right front of the reservoir and turning the adjusting screw to the left for a
lower setting. WARNING: NEVER EXCEED THE RATED TONNAGE OF THE
PRESS.
MAINTENANCE
Recommended to replace hydraulic oil every 6 months of machine use. See step 3 in “SET UP”
section for instructions.
LUBRICATION
•Keep all working parts of the press well-oiled for easier operation.
•Keep a light film of oil over the entire surface of the ram to prevent rust.
•Regularly clean off work surfaces and the surrounding work area.

TROUBLESHOOTING
1. If the press loses pressure:
a. Check all tubing joins for leaks and tighten tube nuts.
b. Drain reservoir and remove packing nut (Item 75), valve rod (Item 73), and ball
valve (Item 73). Clean out valve seat and reseat ball valve using a brass rod as a
drift, striking sharply with a hammer. Reassemble valve rod, packing, and packing
nut. Refill reservoir with appropriate oil amount.
c. Leakage past educator inlet check ball (Item 69). Drain reservoir, remove large
pipe plug (Item 71), valve seat (Item 70), and check ball (Item 69). Clean and
inspect seat. Reset ball on seat or replace seat with new part if necessary.
Reassemble with ball above the seat tightening plugs.
d. Worn leather cup or T-ring seal. If none of the previous conditions seem to have
been the cause, the leather cup or T-ring may be worm or damaged. To inspect,
drain oil and remove the work head from the press frame. Remove tube assembly
(Item 144). Set two 4x4 blocks on the table then raise the table channels with the
block up to the bottom of the reservoir applying pressure to the reservoir. Remove
roller brackets from the reservoir and lower the work head using the table.
WARNING: Be sure the stroke indicator rod support is installed in the side of
the piston. If not, insert 1/2"-13 stud or cap screw into the tapped hole in the
piston. This will hold the piston down under spring pressure.
e. Next remove nuts from cylinder flange and lift cylinder off piston. The piston
leather or T-ring seal can now be inspected and replaced if necessary. Press may
be reassembled in reverse order being careful not to damage the lip of the leather
cup or T-ring seal as it enters the cylinder.
Note: A leather cup will only in presses made before 1992 or has a serial number
before 192522.
2. Press will not develop rated tonnage.
a. Dirt under ball valves. Refer to 1 –c above.
b. Worn leather cup or T-ring seal. See 1 –d above.
c. Relief valve is not set properly. This valve is located on the top side near the right
end of the control block at the front of the reservoir. The valve is set at the factory
to bypass oil from the pump back to the reservoir when the press reaches its rated
capacity. The load on the spring (Item 91), which governs the pressure at which
the valve will bypass oil, is adjusted by turning the screw (Item 90) in to increase
pressure or out to decrease pressure. Replace seal (Item 89) and cap nut (Item
88).
Note: We advise that the relief valve not be tampered with after it is once set at
the capacity of the press.

3. Nothing happens when the press is operated.
a. Release valve is open. Be sure the release valve is firmly closed when pressing.
b. If the ram will come down only a fraction of its rated stroke check the oil level in
the reservoir with the ram at the top of its stroke. It should be visible in the sight
window at the side of the reservoir.
4. Press is operating slow.
a. Check the air supply line for restrictions to determine if air motors are getting
ample supply of air.
b. Release valve not closed properly. Release valve must be firmly closed when
using the press.
c. Wrong hydraulic fluid. After considerable research and tests made with the
cooperation of the pump manufacturer it is recommended that Mobil DTE 24 oil or
equivalent is used.
5. Oil is coming out if the air vent.
a. Drain out the spring chamber by removing the 1/8” pipe plug which is put in the
hub or boss that contains the oil seal where the ram extends out of the reservoir.
Once oil is drained, run the press up to full tonnage with pipe plug still removed.
Excessive oil is a sign that the head seal has been damaged. Refer to
troubleshooting reference 1 –d. to replace seal then replace pipe plug.
6. Excessive leakage around the ram.
a. Drain out the spring chamber as instructed above. A small amount of oil in this
chamber facilitates lubricating the bushing the ram passes through and prevents
scoring. However if operation performed on the press is spoiled due to the slight
leakage of oil, remove the pipe plug as described above and connect tube line to
continually drain this chamber.
