SAFETY FIRST!! READ AND UNDERSTAND THE SAFETY INSTRUCTION (
pages 3-6 of
this manual)
BEFORE BEGINNING ANY BACKHOE OPERATION.
DANGER
Failure to obey the following procedures will result in death or serious injury.
•
Avoid contacting overhead wires and underground pipes or cables. Failure to heed may result
in electrocution or explosion.
WARNING
Failure to obey the following procedures could result in death or serious injury.
Never lift this product:
•
above the operator’s eye level OR
•
to a height where visibility is obstructed, whichever is lower.
Use caution when raising loaded bucket. Objects could fall from bucket toward bystanders or operator.
NOTICE Refer to your power unit’s operator’s manual for safe operating limit and use of
counterweights .
TO DIG:
1. Be sure the loader is on solid ground before digging or lifting load.
2. With the loader arms partially raised and the bucket cylinder partially extended, slowly curl the dipper stick toward the
loader (using the loader’s tilt control). The loader arms may need to be lowered or raised and/or the bucket cylinder
extended to allow the bucket to penetrate the soil.
3. As the bucket fills, extend the bucket cylinder and extend the dipper or raise the loader arms to lift the bucket clear of
the hole.
4. The depth of the hole will be controlled by the amount the dipper is extended and the height of the loader arms.
•
Use extreme care when working on hillsides. Always dump loaded bucket on uphill side of backhoe to minimize
possibility of upset.
•
Exercise caution when working close to fences, ditches or on uneven ground.
DO NOT:
•
Dig close to the loader’s wheels or under the loader. This could cause a cave-in and vehicle overturns.
TO DUMP ON GROUND:
•
With the bucket raised clear of the hole, slowly pivot the dipper stick sideways ( right or left ). This will swing the bucket
away from the trench and to the side to dump.
•
Keep loads close to the ground while transporting.
TO CUT A SHALLOW TRENCH:
1. With the loader arms partially raised and the bucket cylinder partially extended, slowly curl the dipperstick toward the
loader (using the loader’s tilt control). The loader arms may need to be lowered or raised to allow the bucket to
penetrate the soil.
2. When the bucket is positioned at the desired depth, slowly back up the loader, keeping the bucket height constant to
cut a shallow amount of soil.
