Check Digging Chain Teeth and Bits
Check teeth (1) for wear every 10 hours. Replace
worn teeth, using Ditch Witch replacement parts
and maintaining original tooth pattern.
For more efficient digging, contact your Ditch
Witch dealer for information about the tooth
pattern best suited to your jobsite.
If using rock chain bits, check that bits rotate
freely. Clean chain and check bits after each use.
Replace bit when carbide cap or insert is worn or
adapter can be damaged.
