SIGNAL WORD
Description of hazard
Consequence of ignoring the warning.
- Action to avoid the hazard.
A blue or grey circle with a white graphical symbol
indicates that an action must be taken.
A red or grey circle with a diagonal bar, possibly with
a black graphical symbol, indicates that an action
must not be taken or must be stopped.
Notes or instructions that make the work easier and
ensure safe operation.
Check the position of the clamp before you tighten
the clamp. 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.
Do not apply more torque than specified even though
water is dripping from the clamp. The condensed
water is most likely coming from the drain hole under
the clamp.
