NOTICE
Greasing the tool bit without down pressure on
the tool will result in grease lling the space
between the piston and the tool bit.
When the breaker is next activated, the piston
will strike the grease at a speed that will cause
the grease to apply great force against the seals
and grease zerk resulting in damage to these
components.
