Load Stabilizer System (Lss) (Optional) - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

6.11 LOAD STABILIZER SYSTEM (LSS) (Optional)

Never operate the load stabilizer system while using the backhoe.
q
The load stabilizer system (LSS) improves the performance of the machine during travel, regardless of the type of
terrain and of the bucket load. It reduces the oscillations while travelling and while carrying loads, at the same time
increasing productivity and the operator's comfort. It also reduces to a minimum the impact forces to which the
machine may be subjected. When the load stabilizer system is in operation, the loader pressure in low position is
limited to that supplied by the weight of the arm and the bucket. The bucket weight is hydraulically cushioned when
the machine is moving. To activate the load stabilizer system (LSS), press the switch positioned on the side
instrument panel (see "3.3.2 pos. 21 - LOAD STABILIZER SYSTEM SWITCH "LSS" (if provided)").
IMPORTANT
If the machine is equipped with safety valves (see "3.3.2 pos. 20 - ELECTRIC SAFETY VALVE SWITCH
q
(if installed)") ) on the front loader, make sure that they are disconnected.
When the operation of the system is not required any longer, move the switch back to the neutral position (LED
off).

ACCUMULATOR
If it is necessary to repair or change the accumulator of the
q
load stabilizer system, contact your Komatsu Dealer.
Failure to comply with this instruction may cause serious
injury and even death.
PRESSURIZING THE LOAD STABILIZER SYSTEM (LSS)
1 - Every time you start the machine or after pauses lasting more
than 30 minutes, press the upper part of the switch (16) and
at the same time lift the loader to the end of stroke, thus
reaching the maximum pressure in the system; in this
condition, release the switch (16).
IMPORTANT
This operation pressurizes the LSS system and therefore
q
ensures optimal performance.
The release of the switch (16) and its automatic return to
q
the neutral position interrupt the pressurization of the
system, but don't connect the system.
2 - To connect the system, lower the loader and press the lower
part of the switch (16), which remains in this position and
comes on to confirm that the system is activated.
3 - The system can be disconnected by moving the switch (16)
to the neutral position (warning light off).
