Baumalight offers customers a series of helpful service & instructional videos and supports the right to repair. These videos show you how to perform your own trouble shooting and repairs which can save you a lot of down time because many things can be fixed on the spot by end users. Also, after the warranty period is over, a lot of money can be saved if you can do things yourself following simple instructions on trouble shooting, maintenance and repairs.

Log Splitter Attachment

Baumalight’s log splitter tool can split pieces of wood and logs up to 12 feet or even 20 ft long. The bit’s bite comes from machining two helical spirals machined into two pieces of steel. The two spirals join at the hardened tip for easy boring into the log.

Stump Planer Attachment

Baumalight’s stump planer attachment operates at a low RPM so that chips are contained during the operation with very little mess to clean up. The planer’s entry tip is hardened for extra-long wear and replaceable for a longer life. The smaller leading blade is made from AR500 steel and the larger clean up blade is made with AR400 steel. Both blades can be sharpened, lowering operating costs.
