Hello Willie or anyone, last fall I purchased a 2006 S60 Genie Straight Stick Boom to complement my 1976 JLG 40F. Recently, the S60 developed an issue that has us puzzled and in need of assistance. Whenever a load is applied (not sure which specific functions trigger it), the engine shuts off. It runs on a Duetz Deisel engine, so initially we suspected a clogged fuel filter due to it being mostly inactive over the winter. We replaced the filter and added fresh fuel, but the problem persists. Any suggestions on what might be causing this issue?
RSIGuy inquired: Can anyone offer assistance with a glitch in my 2006 S60 Genie Straight Stick Boom, which suddenly causes the motor to die when a load is applied? It is powered by a Duetz Deisel engine, and despite changing the fuel filter and adding fresh fuel, the issue persists. Could the engine be operating at the correct RPM as specified in the manual? This should be the first step in troubleshooting. Any suggestions?
Are you ensuring that the engine is running at the specified RPM as outlined in the manual? This should be the first thing to investigate. It is likely that you have a Deutz F4L1011F engine, equipped with an injection pump with an internal governor to maintain engine RPM under different loads. Can you provide more details on how the engine shuts off? Typically, a diesel engine experiencing a fuel supply issue (such as a clogged filter) will not immediately stall like a switched-off ignition. Instead, you may notice a loss of power, decreased RPM, struggling engine performance, and ultimately engine failure due to lack of power. Other potential culprits could be a faulty lift pump or a clogged strainer screen inside the lift pump, commonly found in Deutz engines.
It is unlikely that your machine comes with an inline filter, but some users opt to install one in the fuel supply line. However, many inline filters are designed for gasoline and may not be suitable for diesel fuel. If desired, consider installing an inline strainer in the supply line instead.
Willie59 mentioned that the engine likely belongs to a Deutz F4L1011F, which includes an injection pump with an internal governor to regulate engine RPM when under different loads. If the engine is experiencing issues, it may not stall immediately due to a fuel supply problem. Instead, symptoms such as loss of power, RPM, struggling to run, and eventually shutting down can occur. Potential causes could include a clogged filter, faulty lift pump, or debris clogging the strainer screen in the lift pump.
It's recommended to check the alternator to ensure it is producing the correct voltage and charging the battery properly, as many systems rely on the right voltage. Additionally, consider inspecting the engine limiter board for any issues. It's worth noting that while some users opt to add an inline filter to the fuel supply line, not all inline filters are suitable for diesel fuel. If desired, installing an inline strainer could help prevent potential issues.
I contacted him to confirm the terminology, and he mentioned that if the issue occurs with functions other than just driving, it may not be related to the horse power limiter board. He was uncertain if the 2005 model (not the 2006 one) is equipped with this board. Their inventory includes a 1999 model. He agreed to inspect the strainer screen but was unsure if the problem is fuel-related based on my description. I plan on examining that and thoroughly cleaning all contacts. I look forward to gaining more insight from you and other knowledgeable individuals.
Before troubleshooting further, it's essential to confirm if the engine is running at the optimal RPM as outlined in the manual. Although I haven't used a tachometer, the sound seems to be on point. I initially assumed you were planning to retire and embark on a road trip across Minnesota.
RSIGuy mentioned something about a high engine limiter board. In Genie terms, the horsepower limiter board can be found in the platform control box and regulates the speed of various functions such as the boom lift, swing, and drive. Additionally, many Genie machines have an ignition/start module in the lower control box with a row of LED lights. While I can't remember all the functions it controls since it's been a while since I last worked with Genie machines, I do know that it oversees the ignition circuit and can shut down the engine if needed. It's recommended to inspect this component for any issues.
In the world of Genie equipment, the horsepower limiter board located in the platform control box is responsible for regulating the speed of various functions such as boom lift, swing, and drive. Additionally, many Genie machines feature an ignition/start module with LED lights inside the lower control box. While it has been a while since I last worked on Genie machines and can't remember all the details it controls, I do recall that it manages the ignition circuit and can shut down the engine if necessary. It might be a good idea to investigate further.
I inspected the small fuel filter on the engine and found only a small amount of debris, so that seems fine. There is also an inline filter that has been added, ruling out fuel as the issue. I will check the voltage next, but I'm unsure how to proceed with checking the board in the control panel, especially since Genie has not been responsive to my inquiries. I reached out to them via email last Wednesday and have yet to receive a reply. Perhaps I should have considered purchasing another JLG instead.
Can you provide the serial number for the machine? It's worth noting that many inline fuel filters are designed for gasoline only and may not be compatible with diesel. If you opt for an inline filter, consider using a mesh strainer instead. Do you know the size of the fuel supply line? Is it 5/16 or 3/8 inches?
RSIGuy mentioned not installing a tachometer, but the sound seems accurate. Other comments and speculations were shared regarding retirement and a potential road trip through Minnesota. Retirement is still approximately 18 to 24 months away, but the end is in sight!
Inquire about the serial number of the machine. It is important to note that many inline fuel filters are specific to gasoline and may not work with diesel. When using an inline fuel filter, it is recommended to use a mesh strainer instead. Confirm the size of the fuel supply line, whether it is 5/16 or 3/8 inches. Rest assured, the serial number for this machine is S6005-11510.
My assistant recently installed a diesel filter, but I still need to verify its size at a later time.
User scasey5 inquired about a recurring issue with a stall while using a machine, suggesting testing the machine on propane to identify potential hydraulic or fuel issues. Has the problem been resolved? Another user with a 2005 Diesel machine shared a similar experience of the machine working perfectly before encountering issues. The problem seemed to be isolated to Rabbit mode before occurring in Turtle mode, only to suddenly operate fine later. Have you experienced a similar crazy problem?
New to the forum and seeking assistance with my 1997 Genie S-60 straight boom lift dual fuel with a Ford engine. The issue I'm facing is random stalling - it could happen three times in 5 minutes or not at all for 5 hours. Despite having the fuel tank cleaned, a new fuel pump and lines installed, and all necessary servicing up to date, the problem persists. The engine idles fine without stalling. I am not very mechanically inclined and would appreciate any guidance on resolving this frustrating issue. Additionally, did you manage to identify the problem? I recently experienced a similar issue with my 2005 Diesel model, where it initially worked fine for an hour, then began stalling randomly. The problem seemed isolated to certain modes but then suddenly resolved itself. It's a puzzling situation!
