INGREDIENTS The ingredients must correspond to specific characteristics for every usage.



WARNING: You must respect the operating conditions for the different ingredients.

Hydraulic fluid

Greases

The CASE hydraulic fluid is specially adapted for high pressure and CASE’s hydraulic circuit. The type of fluid to be used depends on the ambient temperature.

The type of grease to be used depends on the ambient temperature.

Temperate climates -20°C to +40°C Fluid type ISO VG 46 CASE reference: POHYDR

Hot climates 0°C to +60°C Fluid type ISO VG 100 CASE reference: POHYPC

Hot and temperate climates -20°C to +60°C Extreme pressure EP NLGI grade 2 grease with molybdenum disulfide.

Cold climates -40°C to +20°C Extreme pressure EP NLGI grade 0 grease.

Cold climates -40°C to +20°C Fluid type ISO VG 22 CASE reference: POHYPF Temperate climate biodegradable fluid: This yellow-coloured fluid is miscible with standard fluid. When introducing this fluid, it is recommended to drain the hydraulic system completely. Fluid type: ISO VG 46 CASE reference: CASYNTH 46 These different grades of fluids must comply with the CASE specification.

Engine oil The CASE No.1 engine oil is recommended for your engine. This oil ensures proper lubrication of your engine for all operating conditions. If you are unable to procure the CASE No.1 Multiperformance or Performance engine oil, use the corresponding oil from the API/CG/CF category. NOTE: Do not put any performance additives or any other additives in the engine housing. The oil changing intervals are indicated in this manual based on tests carried out on CASE lubricants.

Low fuel

Environment

The fuel to be used must comply with the D975 norm of the American Society for Testing and Materials (ASTM).

Before carrying out any maintenance operation on this machine and before throwing away the liquids or lubricants used, always think of the environment. Never throw oil or liquids on the ground and never put them in leaking containers.

Use type No.2 fuel, use of other fuels can cause a loss of engine power and excessive fuel consumption. In cold weather, it is provisionally accepted that a mixture of No.1 and No.2 fuels be used. Contact your fuel supplier. If the temperature drops below the freezing point of the fuel (point where paraffin appears), paraffin crystals in the fuel will cause loss of engine power or starting trouble. IMPORTANT: In cold weather, fill up the reservoir with fuel after each workday, in order to avoid the formation of condensation.

Consult your local centre for ecological recycling for information on the appropriate method for disposing off these substances.

Plastic and resin parts When cleaning plastic parts, on the console, the instrument panel, the indicator and gauges etc., do not use petrol, paraffin, paint solvents, etc. Use only water, soap and a soft cloth. The use of petrol, paraffin, paint solvents, etc. causes discoloration, cracks or deformation of these parts.

Storing fuel Prolonged storage of fuel promotes the accumulation of foreign bodies or condensed moisture in the storage tank. Many engine failures are caused by the presence of water in fuel. The storage tank must be placed outside and the fuel should be maintained at as low a temperature as possible. Drain the condensed moisture at regular intervals.

Antifreeze/anticorrosive Use the antifreeze in all seasons to protect the coolant system from corrosion and to avoid any risk of freezing. In environments with a temperature greater than -36°C, use a 50% mixture of antifreeze in an ethylene glycol base. In environments with a temperature less than -36°C, it is recommended that you use a 40% water and 60% antifreeze mixture.
