Excavation - Woods BH85 Operator's Manual

DIPPER AND BUCKET CONTROLS (Handle 3, Fig-
ure 5)
Pulling the handle back (toward E) moves dipper down
and toward operator; pushing it forward (toward G)
moves it up and away from operator.
Moving the handle left (toward F) curls bucket toward
operator; moving it right (toward H) extends bucket out
away from operator.
Moving the handle left (toward F) curls bucket toward
operator; moving it right (toward H) extends bucket out
away from operator.
Operate the control levers, swinging the boom several
times to practice control. Do not operate the swing
more than 45 degrees each way the first few times.
Gradually increase arc.

EXCAVATION

 Consult local utilities before working. Know
location of all underground cables, pipelines, over-
head wires, and other hazards in working area and
avoid contact.
 Do not use backhoe for craning; it is primarily
designed for digging. Mechanical failures such as
rupture which will cause a load to drop suddenly.
 Do not drive tractor with material in backhoe
bucket.
 Mechanical failures such as hose ruptures will
cause a load to drop. Lifting a heavy load with the
dipper, then operating the boom, could cause
boom to drop. In either case, if anyone is in the
area (maximum reach of bucket) as shown in Fig-
ure 6, serious injury or death could occur.

ARNING
After becoming familiar with the backhoe operation,
practice coordinated use of the controls in a safe open
area at reduced engine speed. Gradually increase
engine speed as the technique is mastered.
Operate backhoe gently and smoothly. Avoid swinging
boom into mainframe. Sudden stopping or jerking
could result in serious damage to tractor and backhoe.
Strive to develop a smooth digging cycle. Avoid abrupt
or jerky movements. This is accomplished by operating
the cylinders to reach the limit of travel.
IMPORTANT: If you become confused during opera-
tion, simply let go of the controls. The valve control
handles will automatically return to neutral.

 Stay clear of steep areas or excavation banks
that are soft or could give away.
