Hand Spindle Pump
CPP1000-M/-L

5. Maintenance and care

The hand spindle pump can be easily cleaned by wiping down with a damp cloth.
No maintenance tasks should be undertaken on the spindle pump. With any clearly
visible signs of wear, it must be sent back to the manufacturer for refurbishment (after
cost estimate).

5.1 Wear parts

The O-rings in the pressure connections are subjected to wear. Both O-rings must be
checked for proper seat and any wear before any calibrating is performed. If neces-
sary, the O-rings must be replaced at regular intervals, or whenever necessary (see
chapter 9. Accessories).
Use original seals only. Seals having deviant measurements,
or materials, or material grades, may cause damage to the
device and test specimen or to the reference instrument, and
pose a danger for the operator.

5.2 Changing the operating liquid

The hydraulic oil should be changed whenever visible contamination is present.
Removing the operating liquid
Open the shut-off valve, by unscrewing it completely.
■
Take the transparent lid off.
■
Draw the liquid out of the reservoir e.g. with a suitable syringe.
■
In addition, any small residual quantities of oil can be drawn off at the pressure
■
connections, by slowly turning the spindle pump, with the shut-off valve closed.
Minute amounts of oil residue may remain in the piping
■
Waste oil must be disposed of according to legal require-
ments.
To refill and vent the system follow the instructions already given in chapter 3.1.2 to
■
