Check Digging Chain Tension
Check digging chain tension every 10 hours and
adjust as needed.
To check:
1. Move boom in horizontal position.
2. Measure distance A from bottom of boom to
chain:
• When 35K chain is correctly tensioned,
distance A is 1.5-2.0” (38-51 mm).
• When 19K chain is correctly tensioned,
distance A is 1-1.5” (25-38 mm).
To adjust tension with adjustment screw:
1. Loosen jam nut on adjustment screw.
2. To tighten digging chain, turn adjustment
screw clockwise. To loosen digging chain,
turn counterclockwise.
3. When proper tension is reached, tighten jam
nut.
NOTICE: Engine oil capacity is 78 oz (2.3 L).
Too much oil will damage the engine.
• Do not overfill.
NOTICE: Overtightening will cause chain
stretch, loss of machine performance, and
possible premature chain failure.
• Use correct chain tension.
