WARNING
●
When leaving the operator’s compartment, switch con-
trol lever lock switch to OFF position, raise the safety
lock lever to the LOCK position. If the control levers are
not locked, and they are touched by mistake, this may
lead to a serious accident.
If the safety lock lever is not raised in the LOCK position
and lock switch is not OFF, the control levers may not be
properly locked. Check that the situation is as shown in
the diagram.
●
When the safety lock lever is being raised, take care not
to touch the work equipment control lever. If the safety
lock lever is not properly locked at the upper position,
the work equipment and swing will move, creating a
potentially dangerous situation.
●
When the safety lock lever is lowered, take care not to
touch the work equipment control lever.
●
In certain conditions it may be possible for the safety
lock lever to contact the left hand arm rest on the opera-
tor seat.
to avoid this, always ensure that the left hand arm rest is
stowed in the fully up position before operating the
safety lock lever.
SAFETY LOCK LEVER
The safety lock lever LOCKS the work equipment, swing, attach-
ment controls and travel functions.
This device is a hydraulic lock, so even if it is in the lock position,
the work equipment control lever will move, but the work equip-
ment and swing motor will not work.
