I get off of work with the first 8 hour workday that I've had in nearly a year and it is fairly nice outside. Arriving at the shop, I decide it is a good day to have the overhead doors open and start to do a little cleaning. Recollecting that the R700's haven't been run in a couple of weeks, they both willingly start with a flip of the keyswitches smoking up the building like posted before. After pulling one truck outside, (R-795), I decide to let it idle and charge the batteries. I then went back into the building, climbed into the RL-797L, and backed it outside parking right next to the prior moved truck and letting it idle also for the same purpose. Walking back into the shop, I then climbing into my A-40, pull out the choke, give her a crank and within 5 seconds a smooth idle is attained. After letting the air build to release the brakes, I then pull this truck outside parking next to the other two. Ahh, life is good in Mack Paradise I feel. After walking back into the shop, I grab me a shop broom and proceed to sweep the center 18X100ft isle that is the center of the building. A customer comes by to discuss moving some equipment from his "old" Ford truck to it's replacement and we gab for about 15 minutes or so discussing world affairs and such. After he departs, I finish up my sweeping job just as it is starting to get dark outside. I then cleaned up the piles, put the broom back into the storage closet and proceed to walk out to bring the trucks back in. Low an behold, the RL has run out of fuel and died while idling!! Damn!! is the first thing I think cause I know first off how hard that truck is to get restarted as it has no hand primer pump on the fuel system. Naturally a fresh five gallons into the tank and it still won't start. Well back into the shop to grab the booster/charger, and 100' extension cord for power. Off with the fuel filters, (in the dark), back to the shop to fill them, back across the yard to reinstall, then the engine finally lights off!! Well, I'm just about dissapointed in myself for letting this happen in the first place and the truck has not left the property except for just a couple of miles since dumping 35 gallons in the tank. It has done a LOT of idling though. I get this truck back into it rightful parking spot in the shop, walk out and what do I discover???? The damned R-795 has done the same thing!!! Geez, now I'm borderline pissed off at myself cause I get to do the whole rigmarole again; And that is exactly what I did too!! The gasser A-40 started right up, and proceeded without delay. That really is nothing out of the ordinary though. An hour and almost a half to get three trucks running and parked. What a joy. Glad it's not always like this. Think I'll take a couple of aspirin and get to bed dreaming of a better day tomorrow. Rob
