Battery System & Runtime

The Bauer Tools cordless chainsaw 19112C-B operates on our 20V lithium-ion battery platform, the same system that powers over 50 tools in our lineup. This compatibility means you can swap batteries between your chainsaw and other cordless tools like our reciprocating saw for maximum flexibility on the job site.
Runtime varies based on wood density and cutting technique. With a 4.0Ah battery, expect 60-80 cuts through 4-inch diameter hardwood branches per charge. A 2.0Ah battery provides approximately 30-40 cuts under the same conditions. We recommend keeping a spare battery charged for extended cutting sessions.
Chain Tensioning & Maintenance

Tool-Free Adjustment System
Our 19112C-B features a side-mounted tensioning knob that requires no wrenches or hex keys. Turn the knob clockwise to tighten the chain when you notice increased slack, or counterclockwise if the chain binds during operation. The entire adjustment takes less than 30 seconds.
Check chain tension before each use by pulling the chain away from the bar. Proper tension allows you to lift the chain approximately 1/8 inch from the guide bar mid-length. The drive links should remain seated in the bar groove throughout this test.
Safety Features & Operation

The 19112C-B incorporates multiple safety systems to protect operators during use. A two-button activation sequence requires you to press the safety lock-off button before squeezing the trigger. This prevents accidental starts when carrying the tool or setting it down.
The front hand guard serves dual purposes as both a physical barrier and chain brake activator. Push the guard forward before starting any cut, and it will stop the chain within milliseconds if kickback occurs. Reset the brake by pulling the guard back toward the handle after each use.

What people are saying


Common Questions About the 19112C-B Chainsaw
No, the 19112C-B ships as a bare tool without battery or charger. This gives you flexibility to use existing Bauer 20V batteries you may already own from other tools in our cordless system.
If you’re new to the Bauer 20V platform, we recommend purchasing at least one 4.0Ah battery and a standard charger alongside your chainsaw. Having two batteries allows you to keep working while one charges.
The 10-inch bar on the 19112C-B effectively handles branches and logs up to 8 inches in diameter. For optimal performance and battery life, we recommend cutting material between 2-6 inches in diameter.
Larger diameter cuts are possible but will consume battery power more quickly and require multiple passes. The saw performs best on softwoods and medium-density hardwoods within the recommended size range.
Runtime depends on battery capacity and cutting conditions. A 4.0Ah battery typically delivers 60-80 cuts through 4-inch hardwood branches before requiring recharge. A 2.0Ah battery provides approximately 30-40 cuts under identical conditions.
Cutting softer woods like pine or cedar extends runtime significantly. Keeping the chain properly tensioned and the oil reservoir filled also maximizes battery efficiency by reducing friction and motor strain.
Yes, always use proper bar and chain oil in the 19112C-B reservoir. Bar oil contains tackifying additives that help it cling to the chain during high-speed operation, providing consistent lubrication.
Motor oil, vegetable oil, and other lubricants lack these additives and can damage the automatic pump mechanism. Using improper oil also voids your warranty coverage. Bar oil is available at any hardware store or home center.
The 19112C-B works well for firewood cutting in residential quantities. With multiple batteries in rotation, you can cut several cords of pre-bucked logs to final length over a weekend.
For professional firewood operations processing multiple cords daily, a gas-powered model offers longer continuous runtime. The cordless design excels when you need to cut firewood without access to power outlets or when working in noise-sensitive areas.
Always wear safety glasses or a face shield, heavy-duty work gloves, and hearing protection when operating any chainsaw. Steel-toe boots provide foot protection in case of accidental drops.
We also recommend wearing long pants and long sleeves made from durable fabric. While the 19112C-B is quieter than gas models, hearing protection remains important during extended use. Chainsaw chaps offer additional leg protection for professional users.
Replace the chain when teeth become excessively worn, damaged, or when the chain no longer cuts efficiently after proper sharpening. Signs include the saw producing sawdust instead of wood chips, requiring heavy pressure to cut, or pulling to one side during operation.
With proper maintenance and tension adjustment, a chain typically lasts through 5-10 sharpening cycles. Hitting dirt, rocks, or nails accelerates wear and may require immediate replacement. Keep a spare chain on hand for uninterrupted work.
