Bosch EPS 100 Original Instructions Manual page 19

�.� Initial start-up
All the actions below must be carried out before you
may use the EPS 100.
!
Do not move the pump lever until the test oil has
been topped up. Air in the system prevents test oil
being conveyed.
i
Before attaching the EPS 100, check whether the
power transmission in the base in guaranteed.
1. Remove transport protection.
2. The thrust piece (Fig. 1, Pos. 8) at the end of the
pump lever must be connected to the piston in the
base by a sleeve.
i
If the thrust member is twisted with the piston, the
pump lever must be relieved and the thrust member
moved to adjust its position.
3. In the correct position, it must be possible to push
down the pump lever without applying force.
Risk of crushing
Fingers may be trapped when correcting the
position of the thrust member.
Exercise extreme caution when carrying out
settings on the thrust member.
4. The EPS 100 must be mounted on a firm and sturdy
table top.
i
The required fastening holes must be taken from the
hole pattern on the base.
i
If the EPS 100 is to be installed in place of a EFEP 60H
nozzle tester, the distance plate 1 682 310 086 with
the EPS 100 hole pattern is required on EFEP 60H as
a special accessory.
5. Test oil reservoir to be topped up with a test oil to
ISO 4113 (max. filling quantity 600 ml).
6. Remove cap from connecting pipe for the test pres-
sure line and attach the specified test pressure line.
7. Open the shutoff valve and press the pump lever
until test oil containing no air bubbles escapes.
If no test oil is conveyed when the pump lever is
pressed (no test oil escaping from the connecting
pipe), the EPS 100 must be relieved (see Section 3.4).
Once the nozzle to be tested has been attached, the
EPS 100 is ready for use.

�.4 Bleeding the ��S ���
!
Exercise caution and ensure cleanliness!
1. Slacken the clamped connection (hexagon socket
screw) and pull off the valve body with pressure
gauge and shutoff valve from the base.
2. Lift the visible valve cone (with pressure spring) of
the return valve from the valve body.
!
Do not mix up the valve cones!
3. Raise the valve body by pushing down the pump
lever and hold the pump lever in this position.
4. Take the valve body out of its seat from above (rota-
tional movement).
5. Lift the visible valve cone (with pressure spring) of
the suction valve from the delivery piston.
6. Top up the delivery pistons with clean test oil. The
test oil must cover the delivery piston.
7. Insert the valve cone with pressure spring into the de-
livery piston, ensuring a correct position as you do so.
8. Reinsert the valve body and push it as far as it will
go, the suction valve spring must be guided into the
hole in the valve body.
9. Top up the valve body seat with clean test oil.
10. Reinsert valve cone and pressure spring.
11. Carefully remount the valve body with pressure
gauge and shutoff valve and push up to the stop on
the base, then tighten the screw on the clamped
connection. Tightening torque moment: 30 + 10 Nm.
12. Open the test oil reservoir and press the pump le-
ver until test oil containing no air bubbles escapes.
13. Pull off the test pressure line, close the connecting
pipe and open the sealing screw in the volume
compensating chamber for bleeding.
14. When oil containing no bubbles escapes from the
sealing screw, reclose the volume compensating
chamber. Tightening torque: 50 + 10 Nm.
