INTRODUCTION
Safety rules - Ecology and the environment
STEIGER®
Soil, air, and water quality is important for all industries and life in general. When legislation does not yet rule the
treatment of some of the substances that advanced technology requires, sound judgment should govern the use and
disposal of products of a chemical and petrochemical nature.
Familiarize yourself with the relative legislation applicable to your country, and make sure that you understand this
legislation. Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, anti-freeze,
cleaning agents, etc., with regard to the effect of these substances on man and nature and how to safely store, use,
and dispose of these substances.
Helpful hints
• Avoid the use of cans or other inappropriate pressurized fuel delivery systems to fill tanks. Such delivery systems
may cause considerable spillage.
• In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of these products contain substances
that may be harmful to your health.
• Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.
• Avoid spillage when you drain fluids such as used engine coolant mixtures, engine oil, hydraulic fluid, brake fluid,
etc. Do not mix drained brake fluids or fuels with lubricants. Store all drained fluids safely until you can dispose of
the fluids in a proper way that complies with all local legislation and available resources.
• Do not allow coolant mixtures to get into the soil. Collect and dispose of coolant mixtures properly.
• The air-conditioning system contains gases that should not be released into the atmosphere. Consult an air-condi-
tioning specialist or use a special extractor to recharge the system properly.
• Repair any leaks or defects in the engine cooling system or hydraulic system immediately.
• Do not increase the pressure in a pressurized circuit as this may lead to a component failure.
• Protect hoses during welding. Penetrating weld splatter may burn a hole or weaken hoses, allowing the loss of oils,
coolant, etc.
Battery recycling
Batteries and electric accumulators contain several substances that can have a harmful
effect on the environment if the batteries are not properly recycled after use. Improper
disposal of batteries can contaminate the soil, groundwater, and waterways. CASE IH
strongly recommends that you return all used batteries to a CASE IH dealer, who will
dispose of the used batteries or recycle the used batteries properly. In some countries,
this is a legal requirement.
Mandatory battery recycling
NOTE: The following requirements are mandatory in Brazil.
Batteries are made of lead plates and a sulfuric acid solution. Because batteries contain heavy metals such as lead,
CONAMA Resolution 401/2008 requires you to return all used batteries to the battery dealer when you replace any
batteries. Do not dispose of batteries in your household garbage.
Points of sale are obliged to:
• Accept the return of your used batteries
• Store the returned batteries in a suitable location
• Send the returned batteries to the battery manufacturer for recycling

Engine - Engine and crankcase
Engine - Change fluid - Changing engine oil and filter
STEIGER®
NOTE: Reduce to 300 hours or less if CASE IH AKCELA UNITEK NO. 1™ SBL CJ-4 is not used.
Change the engine oil and filter every 600 hours or once
a year or before storage, whichever occurs first. Your
dealer has approved oil and filters. Do not use other
types of oil or filters.
NOTE: For best results change the oil and filter while the
engine is still warm to the touch from operation (not hot).
The tractor must be on a level surface.
Remove the engine side shields.
9L engine
1. Remove the oil pan drain plug and drain the oil from the
engine into a container.
2. After all oil has drained, install new washer 98474302
on drain plug, center washer on plug and install drain
plug. Torque drain plug to 30 N·m (22 lb ft).
3. Clean the area around the filter head and housing on
the left side of the engine. Place a container under the
oil filter and turn the filter housing counterclockwise to
loosen with a 51 mm (2 in) wrench. After all oil has
drained from the filter, remove the housing with filter.
RAIL13TR04406AA 1
4. Install the new filter cartridge and O-ring. Lightly oil new
O-ring.
4. Reinstall the filter assembly onto the tractor. Do not

6. Operate the engine for five minutes at 1000 RPM.
Check for oil leaks at the filter base and drain plug.

the engine. Use a 19 mm (0.75 in) socket to open drain
on bottom of housing. This will allow oil to drain from
the housing. After oil is drained, turn the filter housing
counterclockwise to loosen with a 51 mm (2 in) wrench
and remove the filter housing.
