Very good. Easy to use. Perfect "side dish" for users who don't need full PDF Writer needs. Has just been saving me hours in handwriting out form information

I found it a bit difficult to navigate text changes and then the printed format is not the correct size needed for the IRS. I had to spend time reopening on desktop to make changes and print.

I needed to find a template that I could use for Certified Payrolls for a small job we are working on. PDFfiller has helped me meet my deadlines. It also continues to help me as we work on this project by duplicating my existing Certified Payroll Form and updating it week by week so I do not have to retype information again. It lets me cut, copy, and paste just like I was working on a Word document; this feature saves me a lot of time.

This has been my favorite pdf program of all time. I do not work I am a happy homemaker and have a special needs son and have a lot of documents to file and fill and fax for him. This is the best program. The price is a bit high for me but it's worth it at times when I need to do something that other pdf programs just can't do it.

How do you use oil seals?
For the oil seal to operate correctly, the seal lip must be aligned with the medium to be sealed. To make it easier to slide over the shaft, both the shaft and the oil seal lip must be lubricated properly beforehand with grease or oil. Oil seals with a leather seal lip must be soaked in oil for some time in advance.
How do oil seals work?
How do Oil seals work? The common radial oil seals works by creating a thin layer of oil between the rubber sealing lip and the shaft which results in the oil lifting the sealing lip clear of the shaft. This thin layer of oil performs a barrier and prevents leakage of the oil past the sealing lip.
How do you install Teflon seals?
Warming the ring in water or oil at 130-140 °F for about 5 minutes will soften the material for easier installation. Always avoid inconsistent stretching or overstretching of the Teflon® seal. To prevent the Teflon® ring from snapping into the wrong groove, cover wear ring grooves with plastic tape.
How do you stretch Teflon seals?
If it is difficult to install the O-Ring over a shaft, it may be “stretched” by first immersing the O-Ring in boiling water for a few minutes. This softens and enlarges the O-Ring. After installation, it may be necessary to apply heat to the O-Ring once again, so it will shrink back to a tight fit when cooled.
Which direction does a seal go?
Crank seals on the drive side or primary side are meant to retain the oil level in the chain case. The seal is installed with the spring facing out toward the primary case. Seals in the timing cover are retaining oil pressure in the cover.
What way does an oil seal go?
The seal is installed with the spring facing out toward the primary case. Seals in the timing cover are retaining oil pressure in the cover. An example of this is the timing side crank oil feed seal. The points seal is meant to keep oil away from the contact breaker, so it is installed reverse of the feed seal.
