14.2 Main valve (6210)
14.2.1 Emergency lowering of forks
On the top of the valve block is an emergency lowering valve for the
mast. Both the main lift cylinders and the free lift cylinder are connected
to the emergency lowering valve.
1. Extend the reach carriage fully.
2. Switch off the truck and withdraw the battery cut out connector.
3. Undo the two screws (8 mm allen screws) that hold the protective
plate over the main valve in the reach carriage, and remove the
plate.
4. Open the emergency lowering valve (arrow) (3 mm allen screw).
The screw only needs opening 1½ turns to lower the forks.
IMPORTANT!
The slot-head screw next to the allen screw must NEVER be removed.
5. Once lowering is complete, tighten the screw to 2.5 Nm only.
