Tips and advice that make the work easier.
1.3 Symbols on the product
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.
