Komatsu Galeo PC27MR-2 Operation & Maintence Manual page 117

OPERATION OPERATION
When the sprocket (A) is at the front of the machine.
Push the both travel levers (3) forward slowly to move the
machine off.
4. Switch the travel speed as follows.
When the travel speed selector switch (4) is pressed, the
travel speed can be switched between high speed and low
speed.
Each time the switch is pressed, the travel speed is
switched between low speed and high speed.
When the machine is traveling at high speed, travel speed boost
monitor (5) lights up.
For details of the travel speed values, see "SPECIFICATIONS
(PAGE 5-2)".
REMARK
When the engine is started, the travel speed is automatically set to low speed.
When traveling at high speed, if the machine travels on soft ground or up a slope and the load increases, the
travel is automatically switched to low speed travel, so there is no need to operate the switch. The travel speed
boost monitor displays stays lighted up.
When the load is reduced, the travel system returns to high speed travel.
5. Check that the travel alarm sounds.
If the alarm does not sounds, please contact your Komatsu distributor for repairs.
