Hi all.
I have a GP25K with a mast drift (lowering) issue.
It happens in all stages of lift. I repacked the secondary cylinders a year ago. This issue came on suddenly in the last week.
I'm suspecting a load holding valve issue, and I have the parts breakdown for the HCV but they don't list a holding valve in the diagram. Anyone have a hydraulic schematic for this unit they can share?
Thanks.

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
