Use Of The Emergency Stop Switch; During Repair Work; High-Pressure Hoses - Bosch EPS 118 Original Instructions Manual

4.1.1

Use of the EMERGENCY STOP switch

¶
Only use the EMERGENCY STOP switch in case of
emergency.
4.1.2

During repair work

When performing any work, follow the instructions for
switching on and off in the operating instructions along
with the servicing instructions!
Component parts and larger assemblies are
to be carefully attached to lifting gear on
replacement and secured to avoid any haz-
ards. Only use suitable lifting gear in proper
working order and loadbearing elements with
an adequate capacity. Never stand or work
under suspended loads.
¶
Fit and check the safety systems immediately follow-
ing completion of servicing and repair work.
¶
Always re-tighten bolted joints to the specified
torque after servicing and repair work.

High-pressure hoses

!
The high-pressure hose is a safety component which
must be replaced if damaged. High-pressure hose
repair is not permissible. In addition, the high-pres-
sure hose must be replaced every 2 years.
¶
Always check the high-pressure hose for external
damage prior to connection.
¶
The high-pressure hose must be replaced in the
following situations:
$
Union nuts stiff.
$
Sealing cones deformed or damaged.
$
Cracks, brittle areas, blistering and leakage at the
hose jacket.
$
Leakage at the hose fittings.
¶
Never twist the high-pressure hose as torsion could
damage the hose inlays.
¶
Ensure large bending radius when connecting the
high-pressure hose, as small bending radii reduce
the cross-section. The smallest permissible bending
radius is r = 90 mm.
¶
The bending radius should not start at the fitting
holder but rather approx. 20 mm away from it.
¶
On connection, make sure the high-pressure hose
cannot come into contact with other hoses or ob-
jects during operation. Vibration may lead to abra-
sion at contact points.
¶
Always comply with the specified tightening torque
when connecting the high-pressure hose.
¶
Replace the high-pressure hose every 2 years. The
reference date is the date of manufacture on the
high-pressure hose.
