Air filter maintenance

March 22, 2011 By Mr. Weingartz Leave a Comment

Q: I have an air filter with a paper inside and a foam piece around the outside. Do I need to change both every year?

A: No. The outside foam pre-cleaner is designed to catch most of the larger dust and debris particles with the paper filter being the last defense for the engine. Most of the foam filters are designed to be able to be washed out with soap and water instead of needing replacement each time. After you wash out the foam, let it air-dry completely and then squeeze a few drops of motor oil through the filter. This will help it trap the dust as it enters the filter. The inside paper filter cannot be cleaned and needs to be replaced when the grooves become dirty (hold it up to light – if you can’t see light all the way through, it’s time for a new one).

Replace an edger blade each season

March 21, 2011 By Mr. Weingartz Leave a Comment

Q: I have a walk behind lawn edger. I use it to edge my driveway and sidewalks – I live on a corner lot so it gets used a lot. When should I replace the edger blade?

A: Edger blades vary in length from 8 to 10 inches when new; you should be able to go through a season without replacing the blade. However living on a corner lot your edger is getting used longer then a normal lot. The performance will start to deteriorate after the blade gets to be half the size as it was when it was new. When the blade gets to be half the size as the new one, keep an eye on the performance or just replace it.

Replacement edger blade

March 17, 2011 By Mr. Weingartz Leave a Comment

Q: I went to replace my edger blade and the new one is twice as long as the one I’m replacing. Can that be right?

A: Yes. Unlike lawnmower blades that have the edges dull as they are used, edger blades wear from the friction at the ends of the blade. It is common for customers to bring us a 4” blade that started out 9” long. As the blade shortens, it makes the edging job more cumbersome because it will work slower with that worn down blade. Replacing the blade on an edger is an easy and inexpensive way to improve its performance.
