M-3 Light Weight Stair Rigs

The M-3 Lightweight Stair Drilling Rigs offer a 6' standard bit capacity, with a 3' hand - held option. They allow you to remove the motor for hand - held use. These rigs come with a single - switch outlet control panel with an amp meter (except for CB700 models having an LED amp meter). The 1 - 1/2' square column (mast) has a black oxidized finish. The swivel base and mast can turn 360 degrees, making it easy to drill on stairs. There are 4 leveling screws on the base, and anchor models have a wheel kit. They are lightweight and economical. The slide handle enables drilling in tight areas, and their compact size is perfect for hard - to - reach drilling spots. A ceiling jack helps keep the rig in place as a backup for anchoring or vacuuming the base down, used with a brace piece like a 2x4 or other material. Weka models let you unmount the motor for hand - held use. The engine/motor models include DK12 and DK13 with 14 amp, 115 - volt power, 580/1400/2900 RPM, and various rig types such as complete rigs with or without a vacuum pump and anchor rigs.

Using the M - 3 Lightweight Stair Drilling Rigs is quite straightforward. First, if you need to drill on stairs, adjust the swivel base and mast to the right position as they can turn 360 degrees. Use the 4 leveling screws on the base to make sure the rig is stable. For hard - to - reach areas, take advantage of the compact size and the slide handle. If you prefer hand - held operation, just remove the motor, especially on Weka models. When using the ceiling jack, place it with a brace piece like a 2x4 to keep the rig in place. As for maintenance, regularly check the single - switch outlet control panel and the amp meter to ensure they are working properly. Keep the black oxidized finish on the mast clean. If there are any issues with the motor, like changes in RPM, have it checked by a professional. Always follow safety rules when operating the rig, such as wearing proper safety gear.
