Lubrication
Your cutting systems operates in challenging environments and
depend on sufficient lubrication to minimize wear and extend the
life of operation.
Both bar and chain oils and grease can provide adequate
lubrication to the cutting system when used correctly.
When using grease, ideal settings can vary based on temperature
and other work-site conditions. Always begin by consulting your
manufacturer’s recommendations.
Regular inspection of your cutting system will let you know if any
adjustments are needed.
• Both hydraulic fluid and used motor oil are not approved
lubricants and their use can the warranty of your cutting
system.
• Hydraulic fluid does not provide sufficient properties for
preventing wear of your cutting system.
• Used oils may contain acidic compounds and abrasive
particles that can compromise the cutting system's
effectiveness and increase wear.
