3. Ditching work
Keep the dozer blade at rear of the machine, and insert the blade into the
earth.
Stretch out boom and arm, insert bucket tooth in to ground.
While digging by arm cylinder, adjust bucket angle of cutting over and loading;
or change to dig by bucket cylinder. Do not insert bucket into soil too deep to
cause overloading of hydraulic system. If the bucket can’t move soil, lift the
boom properly will change the situation. When the bucket is full loaded, lift
boom and bucket to proper height, rotate turret to the right dumping place and
unload soil in the bucket
Attention:
1
）
Never touch electric wire in the air.
2
）
Get to know underground pipeline and electric wire in working site before
start digging job in case damaging underground pipeline and electric shock.
3
）
In case of electric shock, please remain on seat, and warm the others not to
come close the machine. Drive the excavator to safety area first, leave the
machine after electric is cut off.
4. Backfill and smoothing work.
To fill up a ditch, cut over dozer blade into soil to certain depth, then release
dozer blade operating lever, drive the excavator perpendicular to ditch, push
soil in to the ditch by dozer blade.
5. Clean the soil and sand from the bucket
Keep the arm at almost horizon status and bucket at unloading status. If sand
and soil can’t be unloaded, move right joystick from left to right several times,
sand and soil will be shaken off. Do not push or pull bucket cylinder to end of
its moving distance to shake off sand and soil.
6. Notice for relevant parts
A. Notice for crawler
1) Too much varies inside tracks will increase tracks’ working strength and
accelerate wearing.
2) Avoid suddenly turning around the machine on a hard friction ground.
3) Try to avoid touch brine, it will erode the crawler.
4) If the crawler does no use for long, keep it in a dry and cool place.
5) When one of the crawlers is lifted, do not move the other crawler, this will
cause the crawler fray.
6) When machine moving, do not loose the crawler, otherwise crawler may
drop out.
