The warning symbol on the clamp holding the pump
head and pump housing together indicates that there
is a risk of personal injury. See specific warnings
below.
CAUTION
Crushing of feet
Minor or moderate personal injury
- Do not drop the pump head when loosening the
clamp.
CAUTION
Pressurized system
Minor or moderate personal injury
- Pay special attention to any escaping vapor
when loosening the clamp.
Fit and tighten the screw that holds the clamp to 6 ±
0.7 ft-lbs (8 ± 1 Nm). Do not apply more torque than
specified even though water is dripping from the
clamp. The condensation 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.
