Blade & Laser Positioning Chains
Check the blade and laser positioning chains for tension every 100 hours of operation and tension as
necessary. The chains should have approximately 15mm of slack. NOTE: The chain tension affects
cutting accuracy.
See Figure 5-4. To tension the blade and laser positioning chains, unbolt and open the gearbox
housing cover and lasers cover. Using the chain tensioner set the appropriate tension. Loosen the
locking nut. Holding the adjustment bolt, turn the adjustment nut right to tighten the chain or turn the
adjustemnt nut left to loosen the chain. After that, tighten the locking nut. The laser positioning chain
tension is set in the same way.
