from Gehl AL20DX Series II Articulated Compact Utility Loader Operator's Manual 918024 - PDF DOWNLOAD
General Information Warning
NEVER lubricate this unit when any part of the machine is in motion. ALWAYS BE SURE to exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8) BEFORE lubricating this equipment.
It is important to apply sufficient oil and grease to prevent excessive part wear and early failure.
IMPORTANT: Whenever service is performed on hydraulic components (valves, cylinders, hoses, etc.) or transmissions, care must be taken to prevent discharging fluid onto the ground. Catch and dispose of fluid per local waste disposal regulations.
Engine Lubrication
All engine maintenance and lubrication requirements are listed in the engine operator’s manual that is supplied with each loader.
Hydraulic Reservoir
The loader is equipped with an 8 gallon (30 L) hydraulic revervoir. The loader is provided with a dipstick on the hydraulic reservoir cap. Markings on the dipstick represent both full and low (add oil) levels. The resevoir is accessed by raising the lift arms and removing the front Cover. Use hydraulic oil with anti-wear, anti-foam and anti-oxidation additives that conforms to ISO Viscosity Grade 46, such asMobil DTE 15M, Amoco Rykon 46, or BP Energol HLP-HD 46. Use of synthetic hydraulic fluids is not permitted.
The hydraulic oil should be changed every 500 hours (or annually).
IMPORTANT: BE SURE to install the lift arm support device when accessing the hydraulic reservoir.
Greasing
IMPORTANT: Grease all fittings at intervals of operation listed, after pressure washing, and before and after storing unit. Use a good grade of lithium-base grease.
Wipe dirt from the fittings before greasing to prevent dirt from being forced into the bearing or pivot. Replace any missing fittings. Force grease into the fitting until it comes out at the bearing seal or the shaft. To minimize dirt build-up, avoid excessive greasing.
IMPORTANT: In addition to the grease fittings, repack the wheel bearings at least annually.
