4.1 Safety symbols on the
pump
Observe the position of
the clamp before the
clamp is tightened.
Incorrect position of the
clamp will cause leakage
from the pump and
damage the hydraulic
parts in the pump head.
Fit and tighten the screw
holding the clamp to 8
Nm ± 1 Nm. Note: Do not
apply more torque than
specified even though
water is dripping from
the clamp. The water
(condensed) is most
likely coming from the
drain hole under the
clamp.
