1 - to the lubricating system
The hydraulic set consists of the above mentioned components of the hydraulic circuit. It is situated on the left hand side of
bed.
Maintenance: of the hydraulic circuit.
Procedure for cleaning of oil filter :
• screw off the filter tank.
• remove the contaminated filler.
• remove the impurities from the filter-body.
• insert the new filler element.
• screw on the filter tank.
Procedure of dismantling the work cylinder (fig. 5.2):
• dismantle the cover (7)
• disconnect the control switch
• disconnect supply of oil into cylinder
• unscrew two screws M10x35 (8)
• screw instead of these screws two auxiliary screws M10x50
• loosen two screws M10x35
• perform next doosing of flange by unscrew of auxiliary screws
The brake disks are accessable after dismantling the cover (3) and body (5)
Oil exchange procedure:
• take off a cover of driving section.
• screw off a tank lid.
drain oil with suitable device.
