POLISHER SERVICE KIT SPEED CONTROL & CAPACITOR (46/56) FOR POL04

Features

• Genuine Tork Craft electronic service kit for the POL04 rotary polisher.
• Includes speed control module and capacitor (items 46 and 56 on the parts diagram).
• Matched components designed specifically for the POL04 motor and electronics.
• Provides adjustable speed range for cutting, polishing and finishing stages.
• Helps stabilise motor rpm under varying load conditions.
• Suitable for regular professional use in workshops and detailing environments.

Benefits

• Restores reliable variable speed control to a tired POL04 polisher.
• Reduces speed surging, hunting and flat spots when adjusting the dial.
• Improves control at low speeds for sensitive surfaces and final finishing.
• Helps protect the motor and switchgear from erratic electrical behaviour.
• Extends the working life of the tool instead of replacing the complete machine.
• Kit format simplifies repairs by pairing the key electronic components.

Extra Information

Typical symptoms that the speed controller and capacitor may need attention include the polisher running only on maximum, cutting out when you adjust the speed, failing to hold a steady rpm under light load, or hesitating and pulsing as you work. Once the cable, brushes and main switch have been checked, the electronic control set is often the next logical step in fault finding.

The POL04-SK13 components are built specifically for the Tork Craft POL04 rotary polisher, so their ratings, wiring layout and physical size align with the original design. Using the correct matched electronic parts helps maintain safe operation and consistent performance, especially in busy professional environments where the machine sees daily use.

Pro Tip

Pro Tip: Before removing the old speed controller and capacitor, take clear photos of the wiring layout and note the routing of each lead. After fitting the new POL04-SK13 components, double-check every connection, make sure no wires are pinched, then run the polisher under no load and slowly sweep through the speed range to confirm smooth, even rpm changes before putting the tool back onto paint.

Specifications

Safety

• Always unplug the polisher from the mains before opening the housing or working on internal wiring.
• Allow the tool to cool down fully before handling electronic components.
• Ensure all connections are secure, correctly insulated and routed away from moving parts and sharp edges.
• Refit all covers, guards and screws securely and test the polisher under no load before normal use.
• If you are unsure about electrical repairs, have the work carried out by a qualified technician or an approved service centre.
