Usage Features

Compact Design: The router is designed to be compact, making it suitable for precision work.
Overmolded Grip Area: Provides improved grip and comfort during operation.
Removable Base: The base is easily removable, providing clear access to the collet nut and facilitating use with router adapter plates (e.g., Easy-Jig® Gen 2-3).
On/Off Switch: Located on the front of the motor housing for easy access.
Spindle Lock: A spindle lock button and wrench are provided to securely tighten or loosen the collet nut or SpeedMill™ cutter.
Rack-and-Pinion Depth Adjustment: A smooth rack-and-pinion depth control mechanism allows for quick and easy depth of cut adjustments.
Base Release Lever: A quick release base release lever simplifies the process of attaching and detaching the motor housing from the base.
Adjusting Tool Base Locking Lever: The locking lever tension can be adjusted via a tension hex nut to ensure the tool base is securely fastened and does not slip during milling.
Fixed Speed: The router operates at a fixed high speed, eliminating the need for speed adjustments.
Direction of Feed and Thrust: The manual emphasizes feeding the router into the workpiece from left to right to counter the cutter's clockwise rotation and prevent kickback.
Proper Rate of Feed: Professional results depend on using a proper feed rate, which is influenced by workpiece hardness, depth of cut, and cutting diameter. Force-feeding should be avoided to prevent motor overload, rough finishes, and damage to the cutting tool or workpiece.
Safety Features: Includes warnings about wearing eye and hearing protection, using dust masks, avoiding contact with rotating parts, securing workpieces, and inspecting cords and damaged parts. Specific warnings are given regarding the high speed of the router and the use of appropriate cutters.

Maintenance Features

General Maintenance: Advises against using solvents for cleaning plastic parts.
Lubrication: A thin coat of oil should be applied to the spindle shaft surfaces after each use to prevent corrosion. The bearings are permanently lubricated and do not require further lubrication under normal operating conditions.
Power Supply Cord Replacement: If the power supply cord is damaged, it must be replaced by an authorized service center.
Brush Replacement: Instructions are provided for replacing the carbon brushes, including removing the brush cap, pulling out the old brush, inserting the new brush, and tightening the brush cap. The manual indicates that carbon brush sets (N) are sold separately.
Inspection: Regular inspection of tool cords, damaged parts, and the quick release locking lever nut tension is recommended to ensure safety and proper operation.
Service: Recommends having the power tool serviced by a qualified repair person using only identical replacement parts. Unauthorized parts or failure to follow maintenance instructions can create a risk of shock or injury.
