• During ripping operation of hard rock, if the rear of ma-
chine is lifted up and severe shoe slip occurs, operate the
ripper control lever to LOWER (c), and the engine speed is
lowered and the shoe slip decreases.
OTHER MODES
REVERSE SLOW MODE
• This mode makes the reverse travel speed slow, and de-
creases the operating effort of the decelerator pedal. Also,
the vibration of machine body is decreased by traveling at
a slow speed.
• Use this mode for the following operations which requires
the slow reverse travel speed.
Reversing after ripping
Reversing after dozing on rock-bed
Reversing after dozing on uphill
Operation on rough ground or soft rocky ground
• When the reverse slow mode and the shoe slip control
mode are used in combination, the one whose set travel speed is lower has a priority.
• Available gear speed: R1, R2, R3
• Applicable operation: Traveling on rocky terrain, Traveling downhill on steep slope
REMARK
For the setting method of reverse slow mode, see “REVERSE SLOW MODE SWITCH”.
(Example)
While driving the machine on the rock-bed, if you feel that the
reverse travel speed is too fast, turn on the reverse slow mode.
Reverse travel speed becomes slow.
