injury may result.
1.
Oil all chains with Dexron III ATF every fifty hours of operation.
CAUTION!
Do not use chain lube. It causes sawdust
buildup in chain links.
2.
Apply a thin film of a NLGI No. 2 grade lithium grease to the blade guide arm every fifty
hours of operation to help prevent it from rusting.
3.
Adjust the blade guide arm drive chain as necessary to prevent the arm from slipping. To
adjust the chain, loosen the blade guide arm motor mounting plate bolts and slide the
motor to take slack out of the chain.
See Figure 5-5.
Proper routing of the blade guide arm drive chain is shown below.

with a NLGI No. 2 grade lithium grease every fifty hours of operation.
