MACHINE OPERATIONS AND CONTROLS
PROHIBITION OF OPERATIONS WHEN MACHINE IS NOT STABLE
If the machine is operated while its undercarriage is unstable,
torsional loads occur in the frames and can shorten the service
life of the machine.
In this case, prepare an embankment, etc. in front of the track
to stabilize the machine.
PROHIBITION OF SWINGING OR TRAVELLING WHEN ROCK IS ON TOP OF
TRACK ASSEMBLY
If the machine travels or swings with crushed stones, soil, or
sand on the track, they hit and damage the undercover and
frame. In the worst case, the hydraulic components are dam-
aged and a serious accident can result.
During operation, keep checking the track top for crushed
stones, soil, and sand.
PROHIBITION OF SUDDEN LEVER OR PEDAL SHIFT DURING HIGH SPEED
TRAVEL
(1) Do not operate the levers and pedals suddenly nor take any
other action to move the machine quickly.
(2) Do not operate the levers or pedals suddenly from FOR-
WARD (A) to REVERSE (B) (or from REVERSE (B) to FOR-
WARD (A)).
(3) Do not operate the levers or pedals suddenly (do not re-
lease them suddenly) to stop the machine when driving it at
high speed.
