POSTURE OF HYDRAULIC BREAKER TO BE GREASED
Be sure to grease the breaker, holding it in the right posture.
IMPORTANT
If grease is injected with the breaker in the wrong position,
q
the breaker circuit will receive more grease than necessary.
Consequently, soil and sand may penetrate in the hydraulic
circuit and damage the hydraulic equipment while the
breaker is being used.
Therefore, make sure to carry out the greasing operation
with the breaker in the correct position.
