1. Insert an M3x25 socket cap screw into the bellows piston through the bellow port (see Figure 7
below) such that it
gently
seats on the front cap.
Failure to do this will result in loss of oil.
2. With the drive unit held back up and jaws down, gently unscrew the oil plug on the back of the
unit; if the oil level is not near the top of the opening there could be a leaking seal and you should
contact your customer service representative.
3. Gently dip your finger in (do not splash out too much oil) and test the quality. The oil should have
a slick feel and should not be gritty or excessively dirty. If the oil is extremely degraded or dirty,
contact your customer service representative for an oil change or to receive a kit to change the
oil.
4. Before replacing the oil plug, top up the oil so that it is filled to the brim
– use Schaeffer’s ISO 22
food safe hydraulic oil.
Failure to top up the oil can result in air inside the housing, loss of
pressure compensation and failure at depth.

Dislodging The Centre Actuator
NEVER
operate the Manipulator without a jaw-set attached. If it has been operated without a jaw-set
attached and the centre actuator has become jammed and cannot be moved with maximum power from
the controller, the following procedure can be undertaken which
may
solve the issue.
While Extended
If the centre actuator is jammed in the fully extended position, without a jaw-set attached, try to close the
actuator with full force from the controller while gently tapping on the tip of the rod with a light hammer.
Make sure the housing is secured to a table or surface to provide stability.
If the actuator is jammed in the closed position, follow one of the following procedures.
Preferred:
1. Locate a flat slotted tool that can fit in the groove at the end of the centre actuator. The slot
should be 5.3
– 6mm [0.21 – 0.24in] wide, and the tool should have a thickness no greater than
3mm [0.12in].
2. Place the manipulator onto a table.
3. Insert the tool into the actuator end groove and brace it against the edge of the table.
