HYDRAULIC LIFT OPERATION
SEQUENCE VALVE SETTING. (7, 9 & 11 Gang only)
Fig.12
If the main (center five) reel assemblies start to lower
before the wing frames/reels have finished their cycle, the
Sequence Valve requires re-setting, as follows :
• Back-off the Jam-nut.
• With a 3/16 Allen Key turn the Sequence Valve
Adjuster one half turn ‘INWARD’.
• Raise the reel assemblies.
• Start ‘lowering’ the reels until they are fully down.
The main reels should not move.
• Back-off the Sequence Valve pressure adjuster
until the main reels start to ‘lower’ when ‘DOWN’ is
selected on the Control Valve.
• Tighten the Jam-nut.
NOTE
If the main reels do not go ‘DOWN’, the Sequence Valve
Adjuster is ‘IN’ too far.
CAUTION
If the Wing Frames drop with a ‘BANG’, check that the
Kick Springs are not ‘seized-up’ or damaged.
