Working in water and on boggy ground
Be very careful when working on boggy ground.
In case that one track gets bogged
If one track gets bogged down, raise this track using
the bucket and put a plank under the track.
NOTICE
When the machine is lifted with the aid of the boom
or the dipper arm, the bottom of the bucket should
rest on the ground not the bucket teeth.
Set the angle between boom and dipper arm at 90
° ~ 110 °.
After working in water or escaping from boggy
ground, replenish the grease to the attachment pins
or the areas affected by the water. Check the idler,
rollers and track drive case oil, if contaminated,
change the oil.
In case both tracks get bogged
In case that both tracks get bogged down, put
planks under each track. Thrust the bucket into the
ground, pull with the dipper arm as when digging,
and move the travel lever forward to escape.
Permissible depth of water
NOTICE
Pay attention to the permissible water depth in
order to avoid damage to the machine.
Permissible working depth in water is the center of
top rollers.
Do not fully submerge the top rollers.
Upon leaving the water, make sure all the grease is
replenished in the areas affected by the water, for
example bucket pin and so on, remove the old
grease completely regardless of the maintenance
period. Also check the oil in the travel drive for
contamination, and if necessary, replace it.
