SLOT DOZING WORK
You can carry more soil by dozing in the slot.
Do not perform dozing deeper than blade tip.
Work efficiency is better when starting the excavation work of
the slot from the place near the dumping place.
When you dig the two slots in parallel, keep the soil wide
enough between them so that it does not collapse.
OPERATION ON SLOPE
When you perform the work on a slope, set the machine longi-
tudinal direction on a slope. When you perform the work lateral
direction on a slope, start the work from higher side.
If you raise the blade high, the machine may tip over or it side
slips. It is dangerous.
Keep the blade height lower than 20 to 30 cm from the ground.
When the machine travels on the downhill while no load is ap-
plied, reduce the travel speed with the decelerator pedal.
Apply the brake pedal as needed, be careful not to cause over-
run.
V-SHAPE DITCHING WORK
You can perform the V-shape ditching work with the desired an-
gle by blade tilting operation.
LEVELING WORK
NOTICE
Avoid leveling work on rocky or stony ground. It can damage the blade.
