1.1 Personnel Protection
-Use gloves as often as practical to avoid minor cuts, abrasions and
splinters. When handling steel, always wear leather gloves.
-During wet days, be certain of footing to avoid slips, especially on
hard surfaces such as steel.
-Wear comfortable but fairly tight fitting clothing to avoid snagging
on construction material or equipment.
-Wear hard hats at all times!
-Wear ear plugs to reduce the effects of noise!
-Stay alert to the work around you. Do not get into hurry and forget
the hazards that exist around you, such as traffic and construction
equipment.
-Use only tools designed for the job.
-Inspect tools for damages. Do not use any tool if it appears to be in
less than perfect condition.
-If using a pry tool, think about where the tool will go if it slips, to
avoid being hit or pinched.
-When working in an area where a ladder is required, a hand line
must be used to hoist tools and objects up or down.
-Before using power tools inspect them for damages.
-Hold tools firmly so if they bind, you are ready for the action.
-Position your body so to not loose grip.
-Keep cords and hoses, not in use, out of the working area.

Hydraulic components, although relatively small, transmit great forces.
This fact causes heating up of the components under normal operating conditions.
The temperature of the medium shall be permanently checked and must not exceed
the manufacturer's specifications.
2.5.6
Hydraulic pipes, hoses and screwed couplings shall be regularly checked for leaks
and externally visible damages. Damages shall be removed immediately.
Squirting oil can cause injuries and fires.

The center rod which stabilizes the clamping collar is attached to the rear link of
the clamping collar by a cardan joint and to the stabilator by the center bolt.
To compensate the difference of length during oscillating, the stabilator is
mounted movable to the base frame by two guiding blocks, which are also
transferring the torque to the base and consequently to the excavator attachment.
The two lifting cylinders can be operated individually, to make it possible to
adjust the casing to the right or left.
Both cylinders are equipped with spherical bearings on the piston and the rod -
side. This design guarantees the full movability of the clamping collar during
boring.
stroke : 600 mm 23 41/64”
piston- Ø : 220 mm 8 21/32”
rod- Ø : 170 mm 6 11/16”
The stroke of the oscillating cylinders and so the oscillating angle is controlled
by a 4/2-valve on the left hand oscillating cylinder.
The point of switching and so the stroke of the oscillating cylinders, is given by
two stop ends. These stop ends are factory – set!
The base frame is equipped with a retaining device, which consists of two
retaining cylinders and a ring segment.
These two retaining cylinder are operated simultaneous to press the ring segment
onto the casing while the clamping collar is opened during extracting of casings.
stroke : 110 mm 4 21/64”
piston- Ø : 140 mm 5 1/2”
rod – Ø : 110 mm 421/64”
