Tools need different care at different times of year. Gas engines need winterizing. Batteries need temperature management. Cutting tools need sharpening after heavy-use seasons. This checklist organizes maintenance by season so nothing gets missed.
Spring (March to May)
Gas-powered tools startup: fresh fuel (never use fuel left from last season), check the air filter, check the spark plug, change the oil if you didn't before storage. Pull-start the mower, trimmer, and blower before you need them so there is time to fix problems.
Sharpen lawn mower blades. They dulled over last season and sat for months. A sharp blade cuts grass cleanly. A dull blade tears it, leaving brown tips and inviting disease. Remove the blade, sharpen with a bench grinder or file, balance on a nail, and reinstall.
Battery inventory: charge every lithium battery to full, then check voltage after sitting for 24 hours. Batteries that drain significantly overnight are failing and need replacement before they leave you mid-project. This is also the time to check if your platform manufacturer released new higher-capacity batteries.
Inspect extension cords and power strips: look for cracked jackets, bent prongs, and any cord that gets warm during use. Replace damaged cords before outdoor project season starts.
Clean and organize the workshop after winter: sweep, reorganize tool storage, check for rust on tools stored in a non-climate-controlled space. Wipe rusted surfaces with oil, clean with steel wool if needed.
Summer (June to August)
Mid-season sharpening: mower blades (again, halfway through mowing season), pruning shears, hedge trimmer blades, and any cutting tool seeing heavy use.
Check mower and trimmer air filters monthly during heavy-use season. Paper filters clog with grass dust. Foam filters need washing. A clogged filter chokes the engine.
String trimmer line: keep spare spools loaded. Running out of line mid-job means stopping, driving to the store, and losing momentum. Buy line in bulk at the start of season.
Battery temperature management: don't leave lithium batteries in direct sun or in a hot car. Heat above 140F permanently damages cells. Charge batteries in shade or indoors. If a battery feels hot after use, let it cool before charging.
Dust collection maintenance: empty the bag or canister, check the filter, inspect hoses for clogs. Summer workshop use generates the most dust.
Fall (September to November)
Winterize gas engines: run the fuel out completely or add fuel stabilizer and run the engine for 2 minutes to circulate the stabilizer. Old fuel is the number-one cause of spring startup failures. This 5-minute task saves a $75 to $150 carburetor repair.
Change oil in 4-stroke engines (mower, pressure washer, generator) before storage. Used oil contains contaminants that corrode engine internals over the winter.
Clean and store yard tools: hose off soil from shovels, rakes, and hoes. Sharpen edged tools. Apply a light coat of oil to all metal surfaces. Hang them on a wall or in a rack so they are off the floor.
Snow equipment prep (if applicable): inspect the snow blower's shear pins, belts, and auger. Check the scraper bar for wear. Start the engine to verify it runs. This is easier to fix now than during the first storm.
Inspect and clean gutters and ladders before winter storms. Check ladder feet for wear and the spreaders for looseness.
Winter (December to February)
Workshop organization and deep maintenance: winter is the season for indoor projects and tool maintenance. Sharpen chisels, plane irons, and any edged hand tools. Clean and wax table saw surfaces, router tables, and drill press tables.
Replace worn parts: brushes on brushed motors, switch assemblies that act up, belts that are cracking. Order replacement parts during the off-season when you have time to wait for shipping.
Calibration check: verify squares, levels, and measuring tools against known references. A speed square that has been dropped repeatedly may be out of true. A tape measure hook that has loosened changes every measurement by 1/16 inch.
Battery storage: store lithium batteries at 40% to 60% charge in a cool (not freezing), dry place. Check them monthly and top off if they drop below 30%. A fully depleted lithium battery that sits for months may not recover.
Tool inventory: this is the time to assess what you own, what you need, and what you could share. Update your FriendsWithTools inventory. Anything you haven't used in 2 years is a candidate for lending to your group.
Frequently Asked Questions
What happens if I don't winterize gas tools?
Gasoline breaks down after 30 days. After 90 days, it forms varnish that clogs the carburetor's tiny jets and passages. In spring, the engine either won't start or runs rough. The fix is a carburetor cleaning ($75 to $150 at a shop) or a carburetor replacement ($30 to $60 in parts plus your labor). Fuel stabilizer costs $4 and takes 2 minutes to add.
Can I store tools in an unheated garage?
Yes, with precautions. Metal tools need a light oil coat to prevent rust (temperature swings cause condensation). Batteries should be brought indoors if temperatures drop below freezing. Rubber hoses and belts can crack in extreme cold. Paint and liquid consumables should come indoors if they have a freeze warning on the label. The tools themselves are fine in the cold; it is the moisture and the accessories that are vulnerable.
