Safety guidelines and symbols

High product safety

Our products correspond to the current level of research and

technology. If the bearing arrangement is designed correctly,

the products are handled and fitted correctly and as agreed and

if they are maintained as instructed, they do not give rise to any

direct hazards.

Follow instructions

This publication describes standard products.

Since these are used in numerous applications, we cannot make

a judgement as to whether any malfunctions will cause harm to

persons or property.

It is always and fundamentally the responsibility of the designer

and user to ensure that all specifications are observed and that all

necessary safety information is communicated to the end user.

This applies in particular to applications in which product failure and

malfunction may constitute a hazard to human beings.

Definition of guidelines

and symbols

The warning and hazard symbols are defined along the lines of

ANSI Z535.6–2006.

The meaning of the guidelines and symbols is as follows:

Warning

If these safety guidelines are not observed, death or serious injury

may occur.

If these safety guidelines are not observed, damage or

malfunctions in the product or the adjacent construction will occur.

Note

There follows additional or more detailed information that must be

observed.

Features The hand pump and accessories are supplied in a sturdy metal case

made from sheet steel. The metal case and parts should be checked

immediately for any damage during transit. The carrier should be

informed of any damage without delay.

Scope of delivery The items included in delivery are shown in Figure 1.

Warning

If the hand pump or accessories are damaged, they must not be

used. Do not attempt to carry out repairs. Any repair work required

should be carried out by Schaeffler KG, Schweinfurt.

Design and

safety guidelines

Intended purpose The hand pump PUMP1000-4L-CONTROL is used to operate

FAG hydraulic nuts. These are used to mount rolling bearings on

a tapered seat, Figure 2.

Note

The hand pump can also be used for dismounting,

see BA 007, FAG Hand Pump Sets.

Qualified personnel The hand pump must only be used by qualified personnel.

A person defined as qualified personnel:

■is authorised to use the hand pump

■has all the necessary knowledge

■is familiar with the safety guidelines

■has read and understood this manual.

Protective equipment Protective equipment is intended to protect personnel against

health hazards.

When working with the hand pump, the following protective

equipment must be used at all times:

■protective goggles

■gloves or oil-based cream.

Hydraulic oil The only hydraulic oils that can be used are:

■any hydraulic oils with a viscosity of 32 mm2/s at +40 °C.

Only clean hydraulic oil should be used.

If the oil is not clean, this may lead to blockage of the filter fitted.

Warning

Hydraulic oil can cause irritation to skin and respiratory passages.

Skin contact should therefore be avoided, vapours and fumes

should not be inhaled. Eyes must be protected against hydraulic oil.

Maximum pressure The hand pump delivers a pressure of up to 1000 bar. The maximum

pressure that can be used with a hydraulic nut is 800 bar.

Warning

800 bar must never be exceeded.

The manometer must be monitored continuously during operation.

Ambient conditions The hand pump should be used under the following ambient

conditions:

■The surface underneath must be even and capable

of supporting loads

■Temperature: 0 °C to +60 °C

■Humidity: max. 90%, no condensation.

Ensure that the ambient conditions are maintained throughout

the operating period.

Initial operation This manual describes the initial operation of the hand pump,

for information on the initial operation of hydraulic nuts

see BA 004, FAG Hydraulic Nuts.

Checking the hand pump Before any use, check the hand pump and the accessories to be

used, Figure 3.

The hand pump can only be put into operation if all the following

questions can be answered with “yes”:

■Is the hand pump  free from corrosion, cracks and damage?

■Is the tank  completely filled with a suitable hydraulic oil,

see page 7?

■Is the escape valve easy to move and free from damage?

■Is the battery in digital manometer  in acceptable condition

(if not, see the section Changing the battery, page 20)?

■Is the high pressure hose  free from damage and kinks?

■Is the high pressure hose suitable for at least 1000 bar?

■Is the required stroke volume set

(see the section Setting the stroke volume, page 9)?

Warning

If the hand pump or accessories are damaged, they must not be

used. Do not attempt to carry out repairs. Any repair work required

should be carried out by Schaeffler KG, Schweinfurt.

Setting the stroke volume The stroke volume of the hand pump can be adjusted as a function

of the hydraulic nut used.

Spacer ring The spacer ring (half ring) restricts the stroke and thus reduces

the stroke volume. The volume without a spacer ring (half ring)

is 0,9 cm3 per stroke, when the spacer ring (half ring) is mounted,

0,2 cm3of hydraulic oil is pressed into the hydraulic nut on

a complete stroke.

The spacer ring (half ring) should be mounted when using:

■HYDNUT50 to HYDNUT150.

Mounting the spacer ring A small flat blade screwdriver is recommended as a mounting tool,

Figure 4:

■Insert the spacer ring (half ring) (position A, )

■Press the arm of the hand pump down almost to the stop

■Rotate the spacer ring (half ring) by 180° into position B, .

Dismounting the spacer ring ■Press the arm down almost to the stop

■Rotate the spacer ring (half ring) by 180° into position A, 

■Move the arm upwards

■Remove the spacer ring (half ring).

Do not replace the spacer ring (half ring) during operation of

the pump. Any inaccuracies in the displacement distance can

damage the bearing.

Hand pump

Operation The mounting operation begins with mounting of the rolling bearing

on the tapered seat, Figure 5. Slide the rolling bearing gently onto

the shaft or slide the mounting sleeve into the original position.

A suitable hydraulic nut is then screwed onto the shaft and the hand

pump is connected. The hand pump is then operated until

the pressure to reach the start position is achieved. The hand pump

is now operated (number of strokes in accordance with the table)

until the rolling bearing has been driven up the required

displacement distance and the end position is achieved.

The pressure is then released and the hydraulic oil flows back into

the pump, after which the pump can be removed.

Note

In order to avoid delays during mounting, we recommend that

the initial pressure and the number of strokes is determined before

the start of mounting.

Mounting the rolling bearing Slide the rolling bearing gently onto the shaft. In this way,

it is possible to avoid sliding the rolling bearing on further than

the start position.

If the rolling bearing is slid on further than the start position,

the radial clearance is too small.

Mounting the hydraulic nut Locate the hydraulic nut on the tapered shaft or withdrawal sleeve.

Screw a coupling nipple into the hydraulic nut.
