Expert Operational Guidance

To ensure optimal performance and longevity of your equipment, please note the following technical considerations:

• Power Requirements: This unit operates on 3-Phase 440V power. Ensure your facility electrical infrastructure meets these specifications before installation.
• Air Consumption Management: As an industrial-grade tool, this grinder is designed for high-capacity workflows. If your setup involves auxiliary pneumatic components, please ensure your compressor capacity is rated for continuous duty cycles. We recommend verifying your shop air system's CFM output against the tool's peak demand to maintain consistent pressure and prevent premature compressor wear.
