Safety recommendations
As high pressures constitute a potential safety risk, the following must be considered:
• The equipment should only be operated by trained personnel.
• Always follow these instructions for use.
• Check the pressure gauge carefully before use. Never use even slightly damaged
components.
• Never use the pressure gauge above the stated maximum pressure of 100 MPa
(14,500 psi).
• Never modify the pressure gauge.
• Batteries represent a choking hazard. Keep batteries away from children.
• Only use clean, recommended hydraulic oils (e.g. SKF LHMF 300, LHDF 900 or
similar).
• In case of any uncertainties as regards the use of the pressure gauge, contact SKF.
Note:
These instructions refer to TMJG 100D high precision digital pressure gauges with a
serial number prexed by the letter E. (e.g. E03220123).
1. Application
The high precision digital pressure gauge TMJG 100D is designed to accurately measure
hydraulic pressures up to 100 MPa (14,500 psi). A high precision digital pressure gauge is
essential when mounting bearings with the SKF Drive-up Method.
2. Description
The TMJG 100D uses a piezo-resistive element to generate a voltage signal proportional
to the applied pressure. The electronics of the pressure gauge convert this voltage signal
to a presure reading on the display.
The pressure gauge displays the current pressure and the maximum presure on the dual
display. The user can congure the pressure gauge to display readings in MPa or PSI.
The pressure gauge is suitable for use with SKF pumps 729124, TMJL 50 and TMJL 100.
The pressure gauge can also be connected directly to an SKF Hydraulic Nut type HMV.E.

4. Installation
The battery supplied with the TMJG 100D digital
pressure gauge must be installed by the user.
Open the pressure gauge by turning the display
ring beyond the limit stop. Open the battery
compartment and install the battery as shown.
Observe the polarity when tting the battery.
Screw the G 1/4 male port of TMJG 100D into the
female pressure port of the pump or nut. Use the
lower hexagon to tighten the gauge. Loosen the
upper hexagon and rotate the TMJG 100D to the
desired position. Retighten the upper hexagon.
The face of TMJG 100D can be rotated through
355°. This feature allows the TMJG 100D to be
mounted in all possible positions: vertical,
horizontal or upside down. If the face is rotated
more than 355°, the face will detach from the
gauge.

5. Operating instructions
The TMJG 100D has two operating keys. The left key (SELECT) serves to select the
functions and the pressure units. The right key (ENTER) activates the selected function or
pressure unit.
5.1 Activation
Press the SELECT or ENTER key to activate the pressure gauge. The display briey shows
the software version (year/week) and the full-scale pressure range (displayed as 1000.0
bar), followed by the actual pressure on the top display and the most recent maximum
pressure on the bottom display.
5.2 Functions
To select a function, press the SELECT button. Press the ENTER button to conrm the
selection. The function appears in the display for ve seconds. After ve seconds, the
pressure gauge returns to display of the actual pressure and the maximum pressure.
RESET: Press SELECT one time and then press ENTER to reset the maximum pressure.
OFF: Press SELECT two times and then press ENTER to deactivate the pressure gauge.
MANO: Press SELECT three times and then press ENTER to select the display units. The
display shows MPa. Press ENTER to conrm this selection. To change the display units to
PSI, press SELECT. Press ENTER to conrm this selection.
If the maximum pressure of 100 MPa (14,500 psi) is exceeded, OVL (overow) appears in
the display. Reduce the pressure to the application to cancel this warning.
The display is deactivated after 30 minutes to conserve battery life. Press SELECT or
ENTER to reactivate the display.

6. Maintenance
The only maintenance required is replacement of the battery. When the battery is almost
discharged, BAT LOW appears in the upper left corner of the display.
To replace the battery, turn the display ring past the limit stop to open the gauge. Open
the battery compartment and replace the battery (type CR 2430). Dispose of discharged
batteries in accordance with local statutory regulations.
