Frequently Asked Questions

N/A Can the MARTIN® PIT VIPER™ Blade be used on the MARTIN® QC™ #1 standard mainframe?

    Yes, verify mounting location is 2.75 to 3.00 inches.

My Pre-Cleaner keeps flipping through. What is wrong?
    The mounting location may be too far away from the belt. Relocate to the proper dimension. Replace the mainframe or end weldments if they are bent.

My Pre-Cleaner is wearing more in the center of the blade.
    The blade is too wide for this application. Replace with a shorter length blade.
