BACKHOE OPERATING PROCEDURES - Continued
NOTE
Backhoe will dig more material in less time when smooth, short dig cycle is used. Keep each
dig cycle smooth.
Forcing backhoe bucket to dig a load that is too large will cause hydraulic stall. Main relief
valve of hydraulic system will make noise when hydraulic stall occurs. Hydraulic stall will
cause cycle times to be longer, hydraulic fluid temperature to increase, and fuel consumption
to increase.
1. Engage parking brake.
2. Shift direction control lever to neutral position.
3. Start engine.
NOTE
If required, position bottom of backhoe bucket flat on ground to avoid digging into surface
such as soft blacktop.
