66 OPERATING THE BACKHOE
OPERATING THE BACKHOE
OPERATING SPEED
To avoid personal injury:
A Use care when operating on slopes to avoid tip
over. Travel at speed compatible with safe
operation, especially when operating in uneven
terrain, crossing ditches or while turning.
1. This backhoe can be operated at any engine speed
from about 75% of rated rpm to factory rated rpm. The
backhoe is most efficient at rated engine speed.
However, in special digging condition, for optimal fuel
economy, or in residential neighborhood where noise
may be a consideration, the engine speed can be
lowered to about 75% of rated rpm.
2. When operating in temperature below 0 C (32 F), run
the tractor engine below about 50% of rated rpm until
the oil temperature exceeds 0 C (32 F).
BACKHOE CONTROLS
To avoid personal injury:
A For all excavation work, operate the backhoe from
the backhoe operator's seat only.
A Do not tamper with any backhoe control valve
relief pressure setting.
The relief valve is preset at the factory. Changing
the setting can cause overloading of the backhoe
and the tractor and serious personal injury may
result.
The backhoe is controlled by using the 2 lever "joystick"
system. The left lever controls the boom and swing
circuits, and the right lever controls the dipperstick and
bucket circuits. The further the levers are moved from
"NEUTRAL", the faster the component will move. Learn
the "feature" of the controls for smooth and precise
component movement.
BBoom & Swing Lever
Pushing the lever forward will lower the boom, and pulling
it back will raise it.
Movement of the lever to the left will swing the bucket to
the left, and right lever movement will swing to the right.
By moving the lever out of the plus "+" position ; into an
"X" relationship, it is possible to raise or lower and swing
at the same time.
