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