Operating instructions two-hand grease gun GB
8.1 Advises for an ideal operation
NOTE
Since the piston chamber of the grease gun is not lled by spring pressure, but
by the vacuum created by the piston, never open the hand lever jerkily.
 Operate the grease gun with even and steady working strokes.
 Depending on the viscosity of the grease used (based on the NLGI class and
the temperature), the vacuum technology makes it necessary to wait for a
sucient relling of the piston chamber with grease.

The two-hand grease gun needs little care and maintenance.
Because of operator responsibility, the following parts must be checked regularly in order to avoid
environmental, material or personal damage:
