Form No. 50950012/AP0811 identifies this as the factory-issued Gehl SL4640E, SL5240E, 4640E Power2 and 5240E Power2 operator manual PDF: 114 pages written for six skid-steer loader variants, EU builds included. Safety interlocks, guards and every operator control take up a large share of the book, followed by starting, stopping, changing attachments and preparing the loader for transport. When a fault shows up, troubleshooting breaks down electrical, engine and hydrostatic drive problems, and the daily checks run through the air cleaner restriction indicator, hydraulic oil level, tire pressure and drive chain tension. Fill a 4640E crankcase with 9.5 U.S. quarts (9.0 L) when you fit a new filter, and hold wheel nuts at 180 ft.-lbs. (244 N·m), rechecking every two hours until the torque holds. Just you and the loader, nobody to ask. Bookmarks and a text layer speed up lookups, and any page prints for the bench, where oily thumbprints cost you nothing.

Gehl SL4640E, SL5240E Power2 Common Problems This Manual Covers
Gehl SL4640E skid-steer loader getting no response from drive, lift or tilt controls
Check the lift, tilt and drive lock solenoids using the electrical troubleshooting chart on page 85. Verify the safety interlock system is satisfied as described in the controls section starting on page 23. Then work the hydrostatic drive troubleshooting chart for the no response from drive, lift or tilt condition before suspecting anything internal.
Manual Section: Hydrostatic Drive System TroubleshootingEngine cranks and turns over normally on the starter but will not start
Read any ECU flash code and match it in the engine diagnostic chart on page 75, which lists the detection condition and recovery action for each failure. If no code shows, work the engine troubleshooting chart for turns over but will not start, one step at a time, before calling your dealer.
Manual Section: Engine TroubleshootingEngine temperature gauge climbing and engine overheating during steady loading and bucket cycling work
Remove foreign material from the machine as the maintenance checks starting on page 95 describe, then work the engine overheats entry in the engine troubleshooting chart. If the engine temperature gauge reading looks wrong rather than the engine itself, test the gauge using the electrical troubleshooting chart on page 85.
Manual Section: Engine TroubleshootingHydrostatic drive overheating with sluggish acceleration during long days of travel and loading
Check the hydraulic oil level at the reservoir as part of the maintenance checks starting on page 95, and confirm the reservoir capacity for your model in the specifications on pages 99 and 100. Then work the hydrostatic drive troubleshooting chart for sluggish acceleration and drive overheating before putting the loader back to work.
Manual Section: Hydrostatic Drive System TroubleshootingAuxiliary hydraulics will not run the attachment after changing attachments on the loader
Verify the attachment is hooked up correctly by following the changing attachments procedure on page 50. Check the hydraulic oil level as the maintenance checks starting on page 95 describe. If the attachment still will not run, work the auxiliary hydraulics entries in the hydraulic system troubleshooting chart before replacing any parts.
Manual Section: Hydraulic System TroubleshootingWheel nuts loosening and wheel mounting hardware losing torque during the first hours of operation
Torque the wheel nuts to 180 ft.-lbs. (244 N·m) before initial operation, as page 79 specifies, and recheck them every two hours until the wheel mounting hardware holds that torque. While the wrench is out, torque the All-Tach pivots to 240 ft.-lbs. (325 N·m), which page 79 calls for periodically.
Manual Section: Service p. 79Frequently Asked Questions
How do I reset the air filter restriction indicator on a Gehl SL4640E or SL5240E?
To reset the air filter restriction indicator, push the reset button located at the end of the indicator after fitting a clean element. You can verify the need for replacement by starting the engine and adjusting the throttle to full speed; if the indicator does not turn red, the element does not need to be replaced. p. 71
What is the required wheel nut torque for the Gehl SL4640E and SL5240E?
The wheel nut torque must be checked before initial operation and every two hours thereafter until the torque remains at 180 ft.-lbs. (244 N·m). This procedure must be repeated whenever wheels are removed and reinstalled. p. 79
What are the part numbers for the primary and secondary air cleaner elements on the Gehl SL4640E, SL5240E Power2?
The primary air cleaner element is Gehl part number 184146, and the secondary air cleaner element is Gehl part number 184195. p. 62
What is the replacement part number for the hydraulic oil filter element on a Gehl SL4640E, SL5240E Power2?
The replacement part number for the hydraulic oil filter element is 074830. p. 62
What is the engine oil capacity for the SL4640E and SL5240E models?
The engine oil capacity is 9.0 U.S. quarts (8.5 L) without a filter, and 9.5 U.S. quarts (9.0 L) with a new filter. p. 67
