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.
