Description

Overview

The CR-317 is a knob-operated speed control switch for 230 polishing machines, sold as a four-piece pack. One rotary knob steps the tool through five speeds, from slow finishing to faster cutting.

Specifications

  • Model: CR-317
  • Speed settings: 5 positions
  • Control: rotary knob
  • Intended machine: 230 polishing machine
  • Pack quantity: 4 pieces

Purpose

A fixed switch gives one speed for every stage of a polish. The five-position dial moves that choice onto the switch, so buffing, compounding and sanding share one machine.

Applications

  • Speed selection on 230 polishing machines
  • Replacing a worn or failed tool switch
  • Buffing and compounding at a slower pass
  • Sanding and finishing on the same polisher

How to Use

  1. Unplug the tool from mains before opening the housing.
  2. Match the CR-317 connections to those on the original switch.
  3. Fit it so the knob turns freely through all five positions.
  4. Caution: the five positions set speed, not power capacity, so check the tool’s nameplate rating against the switch rating before use.
