DUMP AND RETURN CYCLE

Keep the swing-dump-return cycle as brief as possible. Keep dipper moving outward and start boom swing as soon as the bucket clears the excavation. Continue extending dipper and, as you approach the spoil pile, start to dump bucket.

When bucket is empty, dipper and bucket are in posi- tion to resume digging upon return to the excavation.

TRENCHING AND EXCAVATING

Trenching is the most basic backhoe digging operation. Other operations are variations of this basic function.

To maintain a level trench bottom, set bucket at proper approach angle and while crowding dipper-stick in, continually move bucket curl lever to maintain correct cutting angle. At the same time, place boom control in the full forward (float) position and keep the bucket in the same plane.

When handle is placed in the float position, pressure on both sides of boom cylinder is released.

Digging near center of swing so material may be dumped on either side will produce good results. Never dig near stabilizers.

Continue the trench by moving machine along trench centerline away from existing excavation. Move machine approximately one-half the effective backhoe reach. Moving too far will require excessive down pres- sure for digging and hand clean-up of trench bottom.

SIDE SLOPE TRENCHING￿￿￿￿￿￿￿/ EXCAVATING

„Be careful when swinging loaded bucket on hill- side. Always dump spoil on uphill side of backhoe to minimize rollover possibility.

When operating on a side slope, the backhoe must be positioned using one of these two methods as shown in Figure 8 or Figure 9.

When operating on a side slope, always place the trench spoil on the uphill side.

Level the machine on side slope using the stabilizers.

Figure 8. Level with Stabilizers

When leveling with a cutout, cut a level pad for the uphill side of the machine and place spoil on the down- hill side as shown in Figure 9.

TRANSPORTING

„Always engage swing and boom transport locks and attach Slow Moving Vehicle (SMV) sign before transporting backhoe.

„Power unit must be equipped with ROPS or ROPS cab and seat belt. Keep seat belt securely fastened. Falling off power unit can result in death
