3.2. Description of the individual elements Operation 6. Control lever for special equipment The control lever for special equipment has three switch settings whose functions depend on the type of the used special equip- ment. If the standard bucket, the light-weight material bucket or the forklift truck attachment is attached to the quick-change unit, the control lever for special equipment provides the following functions:
Position 1 = Locking pins for work unit are drawn in Position 0 = Neutral position (locking pins are drawn in; you can pick up the work unit in this position) Position 2 = Locking pins for work unit are extended If the multi-purpose bucket is attached to the quick-change unit, the control lever has the functional assignment described above. If the switching lever for the bucket is in position ‘1’, the multi-purpose bucket is active. You can then operate the multi-purpose bucket via the control lever for spe- cial equipment. It then has the following functions:
2 1 Position 1 = Close multi-purpose bucket Position 0 = Neutral position Position 2 = Open multi-purpose bucket 75_160 If you use attachments requiring a steady oil flow (e.g. brush, snow remover), the control lever has the following functions: Position 1 = Work unit turns backwards Position 0 = Neutral position Position 2 = Work unit turns forward Position 3 = Work unit turns forward in permanent opera- tion (locks in For permanent operation, you must set the control lever to position ‘3’. The control lever locks in this position. NOTE Without connected special equipment, you must not set the control lever for special equipment to switch settings ‘1’, ‘2’ or ‘3’.
If you do not heed this note, the work hydraulic system will operate in order to counteract overpressure thus unnec- essarily heating up the oil. 3-26 WA100M-5 – VEAM280201
