Federal regulations require that propane tanks must be outfitted with an overflow protection device (OPD) and re-certified after 12 years from the date stamped on the tank. Tanks that have been re-certified must then be re-certified every 5 years.

Years ago, one of our salesmen put together a poster of with photos of propane tanks that had not been properly inspected or certified. Some tanks are also in poor condition with rusting and pitting that makes the tank a safety hazard. We’ve compiled those photos here.

Basic Equipment Fixes

Posted: August 8, 2012 by Bunce Rental in Bunce Rental, equipment rental, Rental Tips

A couple weeks ago, we discussed the different options for what we can do when equipment malfunctions on the Job Site, including some fixes we’ll recommend over the phone before we send someone out. This week, we’ll discuss some of the most common fixes we run across when equipment doesn’t perform as expected.

1) Check the fuel switch. Some of our equipment (specifically lawn and garden) have an on/off switch for the fuel. Check to make sure the switch is in the on position. If it’s in the off position, switch it to the on position and try starting the machine again. If you’re unsure if the equipment has a fuel switch, call the rental store to find out.

2) Is the choke on or off? This one can work one of two ways. If the machine is being started cold, check to see if the choke is in the on position. If needed, turn the choke on and try starting the equipment again. Now if the machine is being started after it’s been warmed up either in the rental yard or on the job site, check to see if the choke is in the off position. If you find that the choke is in the on position, move the choke to the off position. The engine may also be flooded at this point. You may need to wait 5-10 minutes before being able to start the equipment.

3) Check fuel and oil levels. If you’ve been running the machine for awhile, check the fuel and oil tanks. If the levels are low, refuel if necessary.

4) Is the equipment on level ground? Some of our equipment needs to be set completely level in order to work properly. Equipment such as scissor lifts and articulating lifts have a feature that if the equipment is not level, an alarm goes off and the machine will not continue to raise up. Even a slight angle can set this feature off. On other equipment such as a pressure washer or texture rig, setting it on even ground can cause the fuels need to run the machine to be positioned in a way that they cannot flow through the machine properly. The machine then does not run properly.

5) Check the air filter. On larger equipment like backhoes and dozers, running the machine for extended periods of time can cause the air filter to clog up and subsequently, the equipment will not run smoothly. If this happens, check and clean the air filter. If you are unsure about how to check and clean the air filter, please call the store you rented the equipment from and our staff will gladly talkĀ  you through the process over the phone.
