28.8 FIRST AND SECOND ATTACHMENT
This option can only be fitted to machines that have the main valve converted to or supplied with 2 attachment
spool additions (8 spools in total)
The arm end valves are set to the flow or stop position as shown in the figure below.
The second attachment when fitted, is permanently set in two way flow with full flow (2-pump) output and full
system pressure.
Attachment pressures can be modified by your local dealer on request and can have different pressures for left
hand and righthand piping by modifying the relief valves in the main control valve portions.
When handling attachments please follow the same procedure and precautions as applied to the first attach-
ment circuit (28.3 attachment mounting/dismounting).
