Power Tool Maintenance: Drills And Saws

By Peter Mathers


Having the right tool for the job is the first step in working efficiently. But that tool also needs to be in good working condition to prove effective. In this article, we'll go over some of the steps needed to keep powered saws and drills in good condition, making them safe and effective on the job.

Hand drills see a whole lot of use. It's a very common, versatile tool that can accomplish many tasks with the right accessories, including drilling holes and sanding, polishing and grinding various surfaces. Due to getting so much love, the drill could easily begin to damage itself, or at least work less efficiently, if some basic maintenance is not undertaken with each use. As drill bits lose their edge, you'll want to sharpen or swap them. A drill may also overheat if used for long periods at a time. You can combat this issue by stopping to let it cool from time to time and keeping the vents and fan clear of debris. Compressed air can remove most blockages, but you may need to dig in with a brush to remove larger chunks.

After you finish using it, a drill should be cleaned to prevent debris from blocking moving parts during the next use. After wiping it down with a cloth and light cleaner, oil can be used to keep the metal pieces clean. Cordless drills with rechargeable batteries should be recharged and maintained per the specs of the manufacturer.

The bread and butter of the modern lumberjack is the chainsaw. Hands down, it is the best handheld tool for cutting through tree trunks, among other uses. It can be a huge asset when working on large projects, but there's also the potential for catastrophic accidents if proper precautions and regular maintenance aren't maintained. Take the time to regularly clean the chainsaw, removing the fuel cap and cleaning the vents of obstructions. You can clean a paper filter by tapping it to knock any pieces of dirt loose. Mesh filters can be cleaned with water and detergents if you unscrew and remove them. Before placing them back in the saw, give them time to completely dry. To clean the muffler, make sure the fuel tank is drained and the spark plug is disconnected first. Then remove the cover.

Pieces that are damaged should obviously be repaired or replaced. Any dirt and contaminants you see should be cleaned. A small brush or wire can be used to clean the areas too small for a cloth. The carburetor should be calibrated properly; otherwise, you may not be able to start the saw. When you finish, make sure every piece and screw is solid and tight in its proper place. While you're at it, you can check the chain and make sure that it's sharp across its entire length and at the proper tightness.
