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–especially an electric screwdriver. There’s not a whole lot that has to be done with a driver, 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.
ASG Tool Balancer
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.
Ready to roll?
• Brace fastened objects securely – before operation, refer to “torque settings” to determine the appropriate torque. Make sure that the fastened objects are securely braced to avoid hazardous rapid rotation of the fastened objects caused by excessive torque or insufficient bracing.
• Set the forward/reverse switch properly before operation. Do not change the switch while the motor is running. Set the forward or reverse switch before operating.
• Use the regulating handle to set the torque. Determine torque output by testing with a torque meter or hand-held spanner torque meter. Keep the torque level from being adjusted by using a cover as needed.
• Follow the directions for your electric screwdriver for inserting a bit. Never hammer or forcibly pull out a bit to remove it.
• Hang the screwdriver up securely (balancer) to prevent damage, e.g., external cracking, internal damage, or a snapped power cord.
• When the selected torque is reached, the clutch assembly automatically disengages and a “click” sound will be heard. Even if the trigger lever or depress force is not released, the power to the motor will be automatically cut off.
• When driving a screw, be sure to grasp the screwdriver firmly to prevent upwards recoil generated by the clutch release to prevent damage.
• Sometimes when you need to remove a screw, the screw won’t come out with the same torque. Raise the torque setting and once removed return to the previous setting. When removing a screw, if the required torque is higher than the screwdriver’s output torque, the clutch may not disengage, causing the user’s hand and arm to be twisted. In this case immediately set the forward/reverse switch to “OFF” to cut the motor power and prevent injury.
Periodically remove the tool from the line and run in a quiet environment to detect anything that sounds like a problem. By listening to the sound of the tool, you can determine if there’s excessive wear or other problems.
Test the tool to make sure it shuts off sharply; similar to the way the tool shuts off when the clutch activates. If there’s coasting after the switch is released, the tool may be worn or damaged.
Depending on the type of screwdriver you have, you should also maintain or inspect
brushes, torque repeatability, chuck or joint shaft, lubrication and power supplies.
Keeping your electric screwdriver in good working order through a maintenance program will prolong the life substantially.
Thank you to ASG for sharing their comprehensive manual on electric screwdriver maintenance.
Alternative, safer solvents eliminate nPB while retaining performance
Manufacturers continually face new regulations and safety concerns. Most recently solvents containing nPB have come under scrutiny and could be banned in the near future. Many manufacturers have already reduced nPB exposure by revising and strengthening workplace-safety practices and policies. Others have created brand new cleaners with chemistries that perform as well or better than those containing nPBs.
Consider these nPB-free flux removers, cleaners and degreasers from Techspray (PWR-4™), Chemtronics (Tri-V™), Microcare, 3M (Novec™) and LPS (LPS® 2.0)—each tested against those with nPBs—each proven to be as effective or more effective than ones containing nPB.
Designed for heavy-duty jobs such as SMT defluxing, removing conformal coatings and defluxing lead-free flux. Choice option for cleaning rosin fluxes. Cleans solder paste, acrylic conformal coatings, light oils and inks; excellent degreaser, no residue
Strong, non-flammable cleaner ideal for removing a variety of fluxes including rosin-based and many no-clean and lead-free fluxes; compatible with most plastics, with the exception of acrylics, polycarbonates, ABS and PS
Heavy-duty cleaner for removing heavy oil, greases and soils; suitable for use on metals and many plastics ( not acrylics, polycarbonates, ABS and PS)
Known as n-propyl bromide nPB, bromopropane, 1-propyl bromide, 1-bromopropane, CAS# 106-94-5
Originally used in the production of pesticides, flavors and fragrances, pharmaceuticals and other chemicals
Since 2007, it has been approved for use under the U.S. EPA’s Significant New Alternatives Policy (SNAP) as a suitable replacement for ozone depleting chemicals and still remains
Meets the Emergency Planning and Community Right-to-Know Act (EPCRA) Section 313(d)(2)(B) statutory listing criteria because it can reasonably be anticipated to cause cancer in humans
Occurs mainly in occupational settings – can affect the nervous system; cause headaches, decreased sensation in the fingers and toes, a drunk-like feeling, irritation of the nose and throat
Not found in any of the 1,699 current and former National Priority List sites identified by the Environmental Protection Agency (EPA)
In the EU, nPB has been classified as reproductive toxicant per Registration, Evaluation, Authorization and Restriction of Chemicals (REACH), which makes it a “substance of very high concern”

Chemtronics – Technical Brief – Reducing Exposure to Toxic Cleaners with Replacement Solvents
You’ve most likely done it—chosen a lesser priced, no-name brand item hoping it will perform as well as the brand name one. Sometimes it works and sometimes it doesn’t. It’s always a risk and generally based on the critical nature and use of the product or past experience. Should you take a risk when considering lower priced stencil rolls?
First you need to understand what you may be losing while believing you’re gaining.
What’s the Diff?
You may not be able to see the difference and be dazzled by the price but you might want to look below the surface before you decide to go the cheaper route. Consider paper towels. You have a bounty (no pun intended) of choices and generally brand name towels promote anything from thicker, to more absorbent, to softer and on and on until you give up trying to compare. Most of us have tried the cheaper version of paper towels. Did you see a difference? Most likely you did and it had to do with quality.
Before Choosing Cheap – Consider This
Off-Brand or Premium Brand Stencil Rolls
We’re all brand aware and we know that some brands have earned the trust of customers because the product does what it says it will do every time. That’s part of the reason you pay a higher price–reliability. Also, keep in mind—most manufacturers will require high-quality, hydroentanged fabric because lower-quality ones can cause problems. Can you afford to sacrifice quality for quantity?
Cue the Glue
Some very cheap stencil rolls use glue fillers to lessen the material costs. The glue used in stencil roll paper made from polyester fibers can actually dissolve and weaken the paper with the application of solvents used in stencil wiping. As a result, if examined by a microscope, you’ll find that more residue has been left behind and caused increased linting. Glue fillers may make the paper cheaper, however what you gain in price, you lose in the paper’s ability to pick up contaminants.
Take a Second When Considering “Seconds”
There’s a reason why they’re called “seconds” and if you’re not sure why a particular batch has that description, you should find out before you buy. Seconds are called “seconds” because they haven’t met the manufacturer’s quality standards for some reason. How will that one decision affect quality on down the line?
No, they really did short you and knowingly. We can revisit the paper towel experience or let’s talk toilet paper. Yes, the roll ran out really fast—but it was cheaper. Hmmm–less for less? You bet your bottom dollar.
There’s no real comparison when truly comparing paper towels and toilet paper to the critical nature of stencil paper rolls. The sophistication that goes into researching and developing efficient and effective stencil rolls pales in comparison. However, as paper goes, they both use the same gimmicks to get you to believe you’re getting more for your money. And, companies like MicroCare have documented proof of rolls being priced significantly lower because the rolls have much less paper on them. If it seems too good to be true, it probably is.
When buying, look for a company that offers unconditional guaranteed quality. For instance, MicroCare not only promises quality but also that their unique MicroWipe FP paper will lower your stencil printing costs.
