MAINTENANCE
SYSTEM CLEAN-UP
• After cutting, run the saw for at least 15 seconds with the water on to flush slurry and debris from
Diamond Chain, guidebar and drive sprocket.
• Wash concrete slurry from saw assembly.
• Remove guidebar and chain. Flush out the chain tensioner and side cover with water. Lubricate
tensioner with grease.
• After cleaning the saw, spray the entire saw body, chain, guidebar, and drive sprocket with
lightweight oil. Using lightweight oil on the saw will minimize rust and help reduce slurry
build up.
