1. Introduction
Thank you for purchasing a Specac product.
The Specac Atlas™ Manual 15T and 25T Hydraulic Presses have
been designed for a wide variety of pressing applications, but they are
specifically suited to the preparation of Br discs using Specac
evacuable pellet die assemblies.
The presses can be adapted to provide heated pressing surfaces with
Specac Heated Platens and a Temperature Controller (P/N GS15515).
These heated pressing surfaces can be used for the preparation of thin
films in conjunction with use of the Constant Thickness Film Maker
Accessory (P/N GS15640). The High Temperature Film Maker
Accessory (P/N GS15800) can also be used with the Specac presses.
(The Heated Platens P/N GS15515 are not required for use with the
High Temperature Film Maker Accessory P/N GS15800 as this
accessory has its own heated pressing surfaces).
The Atlas™ 15T and 25T manual presses work by hand pumping a
hydraulic fluid (oil) to raise a piston and compress a sample held in the
pressing area. The press consists of a pump block assembly, where
the oil is pressurized by the simple pumping action from a handle, and
the sample pressing side, where the pressurized oil is forced under the
piston assembly. When resistance is offered by a sample, the pressure
build up in the system is shown on the 15 or 25 Ton load gauge,
located on the pump block assembly.
In addition to the standard versions of the press providing maximum
tonnage loads of 15 and 25 tons, there are low tonnage gauge
conversion kits available for allowing finer load readings over smaller
ranges. These ranges are from 0-1 tons, 0-2 tons and 0-5 tons. The
lower tonnage gauges are connected additionally in line with either the
standard 15 or 25 ton gauge. With these lower tonnage gauges
switched on, the press can only be used up to the maximum tonnage
load limit of the lower gauge that has been fitted.

3. Unpac ing and Installation
Beware! This press is very heavy and care must be taken
to transport it properly. This will protect you and the press
from accidental damage or injury.
The press leaves the factory in specially designed packaging. It sits on
a wooden pallet and has a thick outer cardboard casing held to the
pallet by three tie straps. There are direction arrows on the casing
indicating which way up the press is to be handled.
To unpack the press first cut the three straps with a sharp knife and lift
up the outer cardboard casing from the pallet.
Fig 1. Atlas™ Manual Hydraulic Press Provided as Packaged
The press has internal transport packing around the top, by the lead
screw handle. (See Fig 1.) This packing is four pieces of cardboard
stacked on top of each other, held tight by the lead screw handle and

supporting the pump handle in an upright position. To remove these
four pieces loosen the lead screw handle (turn anticlockwise) and then
carefully lift them up and over the lead screw handle.
The press is now ready to be lifted off of the wooden pallet. There are
two holes in the upright frame supports on the sample pressing side of
the press (used for vacuum tubing when an evacuable pellet die is in
the press – see Fig 2.). These two holes can be used to lift up and
position the press by passing strong nylon rope through them to
provide a sling. If available, a hoist can be used to lift the press via this
sling. If a hoist is not available, then a minimum of two people will be
required to lift the press. Use heavy-duty gloves and lift the press from
underneath by the base casting. DO NOT ATTEMPT TO LIFT THE
PRESS BY THE LEAD S REW HANDLE OR PUMP HANDLE.
Fig 2. Lifting Holes and Base asting Fixing Holes
Place the press in its working position. In certain circumstances, it may
be necessary to attach the press permanently to a laboratory bench.
Two 10 mm diameter holes are provided in the base casting for this

purpose. (See Fig 2.) It is recommended that M8 diameter bolts are
used to secure the press and that the bench top is at least 25 mm thick
to take the weight of the press.
The press is supplied filled with hydraulic oil and is ready to use. The
only preparation required before operation is to remove the nylon vent
screw (37) from the pump plate (36) of the pump block assembly.
Fig 3. Nylon Vent Screw (Transportation Screw) to Remove
Note: A light smearing of oil is applied around the main pressing piston
area (4 and 5) when the press is supplied as new. It is perfectly
normal and not a sign that oil is leaking.
Please keep the press packing materials for future transportation.
Replacing a press in its packaging is the reverse of the procedure
described previously.
For any inquiries to Specac regarding the press the serial number
must be quoted. The serial number is a five digit number preceded by
a letter of the alphabet e.g. H, and is found engraved on the press at
the rear of the pump block assembly. The serial number is also on the
Test Certificate found at the rear of this manual.

If you need to contact Specac regarding a service or repair issue
relating to an Atlas™ Manual Hydraulic Press, please be as specific as
possible regarding the nature of the enquiry. Please quote the serial
number for the press, identify how the press is being used and provide
as much information as you can.
Where possible, if contacting by email, please provide photographs too
as these can help greatly to understand the nature of the enquiry.
