CAUTION
Crushing of feet
Minor or moderate personal injury
- Do not drop the pump head when
loosening the clamp.
Fit and tighten the screw that holds 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.
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.
Do not insulate the control box or
cover the operating panel.
