Specific safety instructions
• Never carry out work on the fuel system in the vicinity of naked flames or sparks! • Do not smoke when working on the fuel system or when refuelling! • Before refuelling, switch off the engine and remove the ignition key! • Do not refuel in closed rooms! • Wipe away fuel spills immediately! • Keep the machine clean to reduce the risk of fire!
Refuelling

Do not run the fuel tank completely dry. Otherwise, air is drawn into the fuel system. This requires bleeding the fuel system – system – see Bleeding the fuel system on system on page 3-11.
Important! Fill up the tank with the correct fuel type at the end of each working day. This prevents condensation water from forming in the fuel tank over night. Do not fill the tank completely but leave some space for the fuel to expand.

C o o l i n g sy st e m The oil and water cooler is located in the engine compartment, on the right side of the engine. The expansion tank for the coolant is also located in the engine compartment, in front of the oil cooler. – see section 1.10 1. 10 Engine Engine compartment: overview on on page 1-11
Specific safety instructions
• Dirt on the cooling ribs reduces the cooler’s heat dissipation capacity! To avoid this: ☞ Clean the outside of the radiator at regular intervals. Use oil-free compressed air (2
bar max.) to clean. Maintain a certain distance to the radiator to avoid damage to the radiator fins. Clean the radiator from the outside to the inside. Refer to the maintenance plans in the appendix for the cleaning intervals ☞ In dusty or dirty work conditions, clean more frequently than indicated in the mainte-
nance plans
• An insufficient coolan t level reduces the heat dissipation capa city as well and can lead to engine damage! Therefore: ☞ Check the coolant level at regular intervals. Refer to the maintenance plans in the
appendix for the intervals ☞ If coolant must be added frequently, check the cooling system for leakages and/or
contact your dealer! ☞ Never fill in cold water/coolant if the engine is warm! ☞ After filling the expansion tank, make a test run with the engine and check the coolant
level again after switching off the engine
• The use of the wrong coolant can destroy the engine and the cooler. Therefore: an tifreeze compound to t o the coolant – but never more than 50 %. If pos☞ Add enough antifreeze sible use brand-name antifreeze compounds with anticorrosion additives ☞ Observe the coolant compound table – table – see section 2.8 2. 8 Coolant Coolant compound table on table on
page 2-5 ☞ Do not use cooler cleaning compounds if an antifreeze compound has been added to
the coolant – otherwise this causes sludge to form, which can damage the engine
• Once you have filled the expansion tank: ☞ Test run the engine ☞ Switch off the engine ☞ Let the engine cool down ☞ Check the coolant level again
Environment! Use a suitable container to collect the coolant as it drains and dispose of it in an environmentally friendly manner!
3-18
SERV-HB 8003 En – Edition 1.0 * *8003s312.fm
Checking/filling up coolant
Danger ! Never open the coolant tank and never drain coolant if the engine is warm since the cooling system is under high pressure –
Danger of burns! ☞ Wait at least 15 minutes after switching off the engine! ☞ Wear protective gloves and clothing ☞ Open filler cap B to the first notch and allow the pressure to escape ☞ Make sure the coolant temperature is sufficiently low so you can touch the
radiator plug with your hands
Danger ! Antifreeze is flammable and an d poisonous –
Danger of accidents! ☞ Keep away from flames ☞ Avoid eye contact with antifreeze
• If antifr antifreeze eeze comes comes into contact contact with with the the eyes eyes ➥ Immediately rinse with clean water and seek medical assistance
Checking the coolant level ☞ Proceed as follows:
A
• Park the machine on level ground • Switch off the engine! • Fold the control lever base up • Remove the key and carry it with you • Let the engine and the coolant cool down • Open the engine cover

☞ Let the engine cool down ☞ Check the coolant level again ➥ The coolant level must be between the LOW and FULL tank seams ☞ If necessary, fill up coolant and repeat the procedure until the coolant level remains
constant
Important! Check the antifreeze every year before the cold season sets in
Draining coolant
Danger ! Never open the coolant tank and never drain coolant if the engine is warm since the cooling system is under high pressure –
Danger of burns! ☞ Wait at least 10 minutes after switching off the engine! ☞ Wear protective gloves and clothing ☞ Open filler cap 18/B to the first notch and allow the pressure to escape
After the engine has cooled down: ☞ Release overpressure in the radiator ☞ Open the cap to the first notch and allow the pressure to fully escape ☞ Open filler cap 18/B ☞ Open the drain plug of the radiator and drain the coolant ☞ Close the drain plug again ☞ Fill up the radiator with suitable coolant

Bear in mind the following to avoid premature engine wear! ☞ Do not clean the filter cartridge ☞ Replace the filter cartridge when the telltale comes on ☞ Never reuse a damaged filter cartridge ☞ Ensure cleanliness when replacing the filter cartridge!
Telltale 19/31 in the round display element monitors the filter cartridge. 19/B and inside filter 19/C : ☞ Replace outside filter 19/B and • If telltale 31 in the round display element comes on • According to the main tenance plan
Important! For applications in especially dusty environment, environment, the air filter is fitted with an extra inside filter C. Do not clean inside filter C.

Caution! Filter cartridges degrade prematurely when in service in acidic air for longer periods of time. This risk is present for example in acid production facilities, steel and aluminium mills, chemical plants and other nonferrous-metal plants. at the latest after 50 service ☞ Replace outside filter B and inside filter C at hours!
General instructions for air filter maintenance:
• Store filters in their original packaging and in a dry place B
• Do not knock the filter against other objects as you install it • Check air filter attachments, air intake hoses and air filters for damage, and immediately repair or replace if necessary
C
• Check the screws at the induction manifold and the clamps for tightness • Check the function of the dust valve, replace if necessary
