Electric Strike Description
When working near electric cables, remember the following:
• Electricity follows all paths to ground, not just path of least
resistance.
• Pipes, hoses, and cables will conduct electricity back to all
equipment.
• Low voltage current can injure or kill. Almost one-third of
work-related electrocutions result from contact with less than
440 volts.
Most electric strikes are not noticeable, but indications of a strike
include:
• power outage
•smoke
• explosion
• popping noises
• arcing electricity
If any of these occur, assume an electric strike has occurred.

OPERATING TIPS
OPERATING TIPS
• Avoid using badly worn teeth. When replacing teeth, maintain
original pattern. Use Ditch Witch replacement teeth.
• Operate engine at full throttle when working.
• Sight along center of hood to a stake driven beyond end of
trench line for straight trench.
• Use correct length boom. See your Ditch Witch dealer fo r
more information.
• Do not make sharp turns. Lower boom to full depth when
turning.
• If an object becomes lodged in chain, move attachment
speed/direction control to neutral and raise boom slightly.
Reverse chain direction. If object must be removed manually,
turn engine off and engage parking brake.
• When cutting asphalt, start trench in soil at edge of road and
use shortest possible boom at full depth.
• Always start trenching with ground drive speed set at low. If
soil conditions permit optimum digging at higher ground drive
speed, select high.
• Before operating booms equipped with rock chains, check bits
for free rotation. Tap bits lightly with a hammer and turn by
hand. If bits are stuck, remove and clean packed soil from bit
block.
• Carbide bits are recommended for cutting abrasive material,
such as sandstone or frozen sands, gravels or asphalts.
EMERGENCY SHUTDOWN - Turn ignition switch to STOP.
