Komatsu PW130ES-6K Operation & Maintenance Manual page 69

EXPLANATION OF COMPONENTS
When starting the engine, G.O. (general operation) mode is auto-
matically selected. Each time the switch is pressed, the mode
selection changes.
NOTICE
When the breaker is used, never select the H.O. (heavy-
duty operation) mode.
REMARK
H switch is also used for setting "hours" in the clock and M
switch for setting "minutes". see "DISPLAY" on page 66.
2. AUTO-DECELERATION SWITCH (Selection switch)
This switch acts to activate the function that automatically lowers
the engine speed and reduces fuel consumption when the control
lever is at neutral.
ON lights up: Auto-deceleration is actuated.
OFF: Auto-deceleration is cancelled.
Each time the switch is pressed, the auto-deceleration is actuated
or cancelled.
3. TRAVEL SPEED SWITCH
If the Hi-Lo switch is operated when the machine is travelling, the
machine may deviate even when travelling in a straight line. To
prevent this, always stop the machine before operating the travel
speed switch.
This is used to select the three travel speeds.
Lo lights up: Low speed travel
Mi lights up: Mid range speed travel
Hi lights up: High speed travel
When the engine is started, the travel speed is automatically set
to Lo.
When travelling in Hi, the travel speed is automatically adjusted to
match the travel surface on soft ground or when travelling uphill,
so there is no need to operate this switch. The monitor indication
keeps lamp Hi lighted.
NOTE: Switching from Hi to Mi or Lo can only be done when the
machine is stationary and the service brake is applied
(locked).
If the Mi or Lo button is pressed without the service brake
applied the indicator lamp will show selection of the
desired mode but the machine will remain in Hi mode
until such time as the service brake has been fully
applied (locked). Switching from Mi to Lo or Hi or from Lo
to Mi or Hi can be done at any time and whilst travelling.
