HYDRAULIC SYSTEM
A 106 A 107
SINGLE-ACTING HYDRAULIC CYLIN-
DER CONTROL
Single-acting hydraulic cylinder is ever
connected with quick-coupler No "1":
- lifting, - lever is in the rear margin po-
sition (it must be kept by hand in this
position)
- neutral, - lever is in the middle position
and is kept by spring in this position
- lowering, - lever is in the middle,
between neutral and front margin posi-
tion and is automatically locked ( so
called floating position)
DOUBLE-ACTING HYDRAULIC CYLIN-
DER CONTROL
Double-acting hydraulic cylinder is
connected with quick-coupler No "1" for
moving piston rod out of cylinder and
with quick-coupler No "2" for sliding in:
- lifting, lever is in the rear margin po-
sition “a° ( it must be kept by hand in
this position)
- neutral, lever is in the middle position
“b° and is kept by spring in this posi-
tion
- lowering, lever is in the front margin
position “d°
- floating (free) position “c°, lever is in
the middle, between neutral and lower
margin position and is automatically
locked - both quick-couplers are
connected with return line.
Control lever must be moved as
quickly as possible over position
’c" (floating position) at work with
outer circuit double-acting hydra-
ulic cylinder because both sides
of cylinder are connected with
the return line and so the un-
controlled movement of piston
rod can start.
