Hi Maintenance, Goodbye Electric Screwdriver Problems

As we all know, taking good care of your tools pays off in the end and it’s one time when high maintenance is a good thing. There’s not a whole lot that has to be done with an electric screwdriver, however by just giving a bit of attention to your hardworking tool on a regular basis you can really extend the life.

In general, maintenance should begin after about 1000 hours of using your new screwdriver. It’s a good idea to adhere to a schedule so you’ll get in the habit. If you figure 21 working days per month, you’ll do a couple of things every six months. You can account for double and triple shifts as well. Once you begin the cycle you’ll be able to better determine how much maintenance will be necessary and beef it up or pare it down from there.

Designate an area

This may seem silly, however here’s the suggestion anyway. How many times have you put down a screw or small piece, told yourself it’s safe and then not been able to find it when you go back to where you put it. Be sure to put them in a safe place when removing them for screwdriver maintenance—a designated area kept for just this purpose.


Just like with your teeth, e.g., cleanings—prevention goes a long way in extending the age of your screwdriver. One of the most common incidents to cause damage—dropping the screwdriver. Sometimes you’ll see the damage, for example a cracked casing or bit run out – radial or axial. Dropping can also cause the magnet to fracture and the broken pieces could jam the armature or cause the tool to overheat.

A way to prevent dropping is by using a tool balancer or making sure the tool is tethered or put into a tool holster. The tether should be attached to a tool cord that prevents the tool from hitting the floor should it fall.

Keep the cord in good shape

The cord can be just as important as the screwdriver. Kinks, nicks and stretching should be avoided. When connecting, make sure the locking ring fits snuggly to ensure proper grounding and avoid disconnecting the screwdriver. Inspect the cord for cuts and abrasions on the outside. Repair minor cuts or scrapes with electrical tape. Deep cuts to the cord can damage interior wires and the cord should be replaced. To save money, replace the plug if the cut is near the plug.

Check before you power up

  • Use the correct voltage - carefully check the voltage shown on the power supply and manual to determine the correct voltage. Only plug the unit into a power source of the correct voltage.
  • Determine the appropriate torque range - choose the correct screwdriver for the torque you require. To lengthen product life, avoid long-term high torque use.
  • Look for damage - If the power cord is scraped or damaged, immediately unplug and replace it to avoid electric shocks or a short circuit that could cause a fire.
  • Use in an appropriate work environment - to ensure safety, do not use in high temperature, high humidity environments or near flammable materials. Keep the power cord away from tools or equipment that might scrape or melt it.
  • When plugging in or unplugging the power cord, hold the plug firmly. Never yank on the cord.
