4. Routine maintenance, inspection and operational testing of the emergency generator and associated. components must be overseen by a properly trained person [see MSFC(07), Sec. 604.5; NFPA. 99(99), Sec. 3-4.4.1.1(b)3; NFPA 110(99), Sec. 6-4.7; NFPA 110(02), Sec. 8.4.7].
If rain and wet roads are a concern, you should consider replacing your tires when they reach approximately 4/32 of remaining tread depth. Since water can't be compressed, you need enough tread depth to allow it to escape through the tire's grooves.f two of your tires have a lot of remaining tread depth, but you need to replace the other two because they were damaged or have worn out, you should replace them with a pair of tires that come as close as possible to matching your existing tires.
1 If your tires show cracks to the fabric piles, you should replace both the tire and the inner tube (if it's still the original tube that came with that tire). 2  If the two tires on the bicycle are the same age, replace both even though only one may look bad. 3  Otherwise you risk a blowout.1. Place the new tube into the tire ensuring the tub is not twisted at all and fill the tube with a few pumps of air. Putting a few pumps of air in the tube before will help to avoid pinching the tube when putting the tire on the rim.
