Inspect Microtrencher Blade and Bits
Remove blade cover and inspect blade and bits for wear every 100’ (30.5 m), or when performance
declines.
Fixed Bits
Replace blade when bits are worn. See “Change Blade” on page 180.
Rotating Conical Bits
• Check that all bits are rotating freely in bit blocks. If bits are stuck, tap with a brass or rubber mallet.
• Use gauge (shown, p/n 301-1507) to check
bit condition. Replace bits when carbide
components become dull or excessively
worn. Always replace bits and roll pins in
complete sets. Do not mix old and new bits.
Always use new roll pins.
A: Bits okay.
B: Replace bits if outer diameter or length is
excessively worn as indicated by gauge.
Hot parts may cause burns. Do not touch until cool.
To help avoid injury: Do not touch hot blade and bits.
