Safety Instructions
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury when operating power tools.
General Power Tool Safety Warnings
- Work Area Safety: Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
- Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Do not expose power tools to rain or wet conditions.
- Personal Safety: Stay alert, watch what you are doing and use common sense when operating a power tool. Always wear eye protection. Use hearing protection when operating for extended periods.
Sander Specific Safety Warnings
- Always wear appropriate respiratory protection when sanding, especially when sanding materials that produce fine dust.
- Secure the workpiece. A workpiece clamped by a clamping device or in a vise is held more secure than by hand.
- Do not force the power tool. Use the correct power tool for your application.
- Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
Setup
Unpacking
Carefully remove the sander and all accessories from the packaging. Inspect the contents for any damage. Retain the packaging for future storage or transport.

- Adjust the handle to a comfortable position for optimal control and balance during operation.
Installing Sanding Discs

Operating Instructions
Powering On/Off
- Connect the sander to a 120V power outlet.
- To turn the sander ON, depress the trigger switch.
- To turn the sander OFF, release the trigger switch.
Variable Speed Control
The sander features a variable speed trigger dial, allowing adjustment of the OPM (Orbits Per Minute) from 0 to 3,700. Rotate the dial to select the desired speed for your application. Lower speeds are suitable for delicate work, while higher speeds are for aggressive material removal.

Sanding Techniques
- Always start the sander before placing it on the workpiece.
- Apply light, even pressure. Let the sander do the work. Excessive pressure can reduce efficiency and damage the workpiece or tool.
- Move the sander in overlapping passes across the surface.
- For best results, sand with the grain of the wood.
Dust Collection
The adjustable dust shroud can be connected to a vacuum system (not included) to improve the working environment by collecting sanding dust. Ensure the dust shroud is properly attached to the sander and the vacuum hose is securely connected to the shroud's port.
Maintenance
Cleaning
Regularly clean the tool's ventilation openings to prevent overheating. Use a soft brush or compressed air to remove dust and debris. Do not use harsh chemicals or abrasive cleaners.
Pad Replacement
Over time, the hook & loop pad may wear out, reducing its ability to hold sanding discs. To replace the pad, remove the screws securing it to the sander, detach the old pad, and install a new one, ensuring the screws are tightened securely.
Storage
Store the sander in a clean, dry place, out of reach of children. Disconnect it from the power source before storing.
