Cab controls, start-up, driving, loader work with the quickhitch and pallet forks, daily maintenance and full specifications: the Gehl 480 operator manual PDF (OEM ID 918115) takes this all-wheel steer loader through each one across 150 pages. Warning lights get their own overview, so a hydraulic oil temperature or parking brake lamp on your instrument panel means something specific, while the fork load diagrams show what the lift arms can safely carry. Maintenance fills a large share of the book: the model 480 service schedule, lubrication points, cooling system, air filter and V-belt care, tire care, and a log for recording each interval. Plan on about 17 gal. (65 L) for the hydraulic tank and 2.8 gal. (10.5 L) of engine oil with a new filter. An oil change stalls when nobody can recall the fill. Bookmarked and text-searchable, the PDF finds that number in seconds, and your 480 is moving material again the same shift.

Gehl 480 Common Problems This Manual Covers
Gehl 480 all-wheel steer loader diesel engine, after preheating at the start switch, still does not start
Check the parking brake and steering-column control lever positions first, then work through the starting causes on page 98: engine starting temperature, fuel quality, battery and starter. In cold weather, follow the low temperature starting steps on page 45, and use the engine trouble chart on page 99 to narrow down the cause.
Manual Section: Engine Trouble p. 98Engine oil pressure warning light lit on the instrument panel with insufficient oil pressure
Check the engine oil level with the engine stopped and the loader parked level, and add oil as needed. Capacity with filter is 2.8 gal. (10.5 L) per page 125. Confirm what the light means on page 42. If it stays lit, have oil pressure checked against 44 to 65 psi (3.0 to 4.5 bar) at 2300 rpm, page 135.
Manual Section: Indicators and Warning Lights: Overview p. 42Engine and cooling oil temperature warning light comes on and the engine overheats while working
Inspect the engine and hydraulics cooling system following the maintenance section that starts on page 101. Check V-belt tension and re-tension the belt if it is slack. Check the air filter for contamination and confirm the dust valve works, then go through the overheating causes on the engine trouble chart on page 99.
Manual Section: Troubleshooting p. 99Hydraulic oil temperature warning light or hydraulic oil filter indicator lit on the instrument panel
Check the hydraulic oil level with the loader parked on level ground, and add hydraulic oil if it reads low. The tank holds about 17 gal. (65 L) per page 124. Check the hydraulic oil reflux filter monitoring, and confirm what each indicator means on page 42 before you put the lift arms back to work.
Manual Section: Indicators and Warning Lights: Overview p. 42Alternator charge warning light stays lit on the instrument panel with the engine running
Check the battery terminals and cables for corrosion and loose connections, then inspect the alternator wiring and the fuse box. Check V-belt tension and re-tension the belt if it is slack. Confirm what the light means on page 42, then follow the electrical system maintenance steps in the maintenance section starting on page 101.
Manual Section: Electrical system maintenanceEngine runs poorly with insufficient engine output and smoke from the exhaust
Inspect the air filter for contamination, check that the dust valve works, and replace the filter cartridge if it is loaded. Verify fuel quality per page 98; the fuel table on page 124 calls for Grade no. 2-D diesel above 39 °F (4 °C). Compare performance against the rated 59 DIN hp (44 kW) at 2400 rpm on page 135.
Manual Section: Troubleshooting p. 99Frequently Asked Questions
What are the torque specifications for Gehl 480 hardware?
Torque specifications for Gehl hardware are provided in tables on pages 147 and 148. For example, an M10 coarse-pitch bolt (Grade 8, 10.9) requires 49 lb.-ft. (67 Nm), while an M10 fine-pitch bolt (Grade 8, 10.9) requires 55 lb.-ft. (75 Nm). p. 147
What are the replacement specifications for hydraulic hoses and fittings on the Gehl 480?
Hydraulic hoses must be replaced every six years from the date of manufacture, even if they do not appear damaged. The date of manufacture is stated on the flexible line, such as '1 Q/05' for the first quarter of 2005. p. 112
What is the engine oil capacity for the Gehl 480?
The engine oil capacity for the Deutz F4M 2011 engine is 2.8 gallons (10.5 liters) including the filter. p. 125
What is the correct engine valve clearance for the Gehl 480?
The valve clearance for the engine at cold temperature is 0.01 inches (0.3 mm) for the intake valve and 0.02 inches (0.5 mm) for the exhaust valve. p. 135
How often should the air filter cartridge be replaced?
The air filter cartridge should be replaced when the indicator comes on, or at least every 1500 service hours (or yearly). In acidic environments, it must be replaced every 300 service hours. p. 106
