Driver Controlled Differential Lock
Driver Controlled Differential Lock
(Optional on drive axles)
Drive axles may be equipped with a driver controlled
differential lock. This is a servo-controlled, air-actuated traction
device that can be manually controlled inside the cab by the
operator. By actuating a dash-mounted control, the operator
can lock or unlock the differential.
The differential must not be engaged when traveling at
higher speeds or down steep grades with limited traction.
When the differential is fully locked, the vehicle will
have reduced steering capability. Do not use the
differential when driving at higher speeds or loss of
vehicle control, serious injury or death can result.
The differential must not be engaged when traveling
down steep grades when traction is limited. This can
result in loss of vehicle control, damage to
components, serious injury or death. Refer to the axle
manufacturer for the correct operational and
maintenance procedures.
Ignition Switches
The standard ignition switch on the Kalmar tractor is a key
type, similar to the kind found on automobiles. Push button
and other types of ignition switches are installed as optional
equipment.
Key-Type Ignition
There are three positions: OFF, ACCESSORY and
RUN/START. The full left (counterclockwise) position is the
OFF position. The second position to the right (clockwise) is
the ACCESSORY position. The third position to the right
(clockwise) is the RUN/START position.
The RUN/START position is used to engage the starter motor.
Moving the switch to the full right position engages the starter
and upon release of the key, the switch automatically stays in
the RUN position.
The ACCESSORY position activates the tractor's electrical
accessory circuit.
The OFF position cuts all power to the electrical system and
shuts down the engine.
NOTICE
The OFF position on the standard three-position key-type
switch is designed to function as the engine stop. There is no
other engine stop device other than the ignition switch on the
standard Kalmar tractor.
