# Maintain the Machine

## Check chain tension quarterly

This is roughly the deflection you should expect at center

## Lubricate the roller chain annually

Lubricate by using SAE 20 gear Oil. Apply with a soft bristle brush.

## Degrease and lubricate chain every 3 years

Degrease the chain. Simply Green will work fine, if you immediatley dry and relube. Lubricate by using SAE 20 gear Oil. Apply with a soft bristle brush.

## Grease Bearing when needed. Check Quarterly

Grease the bearings if the bearings start to make noise. Use any lithium-based NLGI #2 grease using a grease gun applied to the zerk fitting on the bearing.

Important Note: Overlubrication is a major cause of bearing failures. Please relubricate conservatively when unsure of bearing requirements
