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