To adjust chain with
grease cylinder:
With boom horizontal,
measure distance
from bottom of boom
to chain. When
properly tensioned,
distance should be
0.5" (13 mm).
To tighten digging
chain, pump MPG into
cylinder at check valve zerk.
To loosen digging chain, stand on opposite side of boom
and unscrew check valve zerk to release grease.
Lube Outboard Bearing
Lube outboard auger
bearing every 10
hours with MPG. Clean
zerk before servicing
to prevent
contamination.
As Needed
Check Digging
Chain Rollers,
Sidebars, Pins, and
Bushings
Perform periodic
visual inspections of
digging chain. Check
for wear on rollers (1)
and sidebars (2).
Check pins and
bushing wear by
measuring distance
(3) between chain pins and comparing it to new chain.
Check Digging Chain Teeth and Bits
Inspect digging chain teeth for wear as needed. Replace
worn teeth with new Ditch Witch
®
teeth. Each unit is
equipped with a standard tooth configuration. When
replacing teeth, maintain original tooth pattern.
Depending on soil conditions and type of chain, a
different configuration might produce better results.
Contact your authorized Ditch Witch dealer for more
information about digging teeth patterns.
Alligator chain bits, like teeth, wear out. When tungsten
cap or insert is gone, bit will wear quickly. Replace it
before bit adapter is damaged.
NOTICE:
Do
not
overtighten chain. Overtightening
will cause chain stretch, loss of machine
performance, and possible premature chain failure.
