CAUTION!
Turn the Key Ignition Switch OFF before attempting any maintenance or repairs to this machine.

ENGINE AIR FILTER

The Engine Air Filter (6) is located in the engine compartment. Check the Air Filter Service Indicator (5) before each use of the machine. Do not service the Air Filter
unless the red fl ag is visible in the Service Indicator.
CAUTION!
When servicing the engine air fi lter elements, use extreme caution to prevent dust and dirt from entering the engine.
The Engine Air Filter (6) contains a Primary (outer) and a Safety (inner) Filter Element. The Primary Element may be cleaned twice before being replaced. Replace the
Safety Element every third time that the Primary Filter Element is serviced. Never try to clean the Safety Element.
To clean the Primary Filter Element, remove the cover from the dust cup end of the canister. Then pull out the Primary Element. Clean the Element with compressed
air (maximum pressure 100 psi) or wash it with water (maximum pressure 40 psi). Do not put the Element back into the canister until it is completely dry. To reset the
Air Filter Service Indicator, press down on the top of the indicator.

ENGINE OIL

Check the engine oil level when the machine is parked on a level surface and the engine is cool. Change the engine oil after the fi rst 35 hours of operation and every
100 hours after that. Use 3.3 liters of any SF or SG rated oil meeting API specifi cations and suited to seasonal temperatures. Note: Refer to the Engine Manufacturer's
Operator Manual for these specifi cations. Replace the oil fi lter with every oil change.

HYDRAULIC OIL

WARNING!
To avoid hydraulic oil injection or injury always wear appropriate clothing and eye protection when working with or near hydraulic
system.

IMPORTANT!

Change the Hydraulic Oil Filter after the fi rst 35 hours of operation. After that, change the fi lter when the Hydraulic Filter Light comes
on.
The Hydraulic Oil Reservoir (2) is located under the Engine Hood (1). Check the hydraulic oil in the reservoir after running the machine, while the hydraulic oil is still
warm. Remove the cap from the tank and look to the bottom of the fi ller screen. If the oil level is below the bottom of the fi ller screen, add SAE 10W-30 motor oil until
the bottom of the fi ller screen is covered. Change the oil if major contamination from a mechanical failure occurs.

ENGINE COOLANT

Check the engine coolant level every 50 hours. Lift the Engine Hood (1) and allow the engine to cool completely. Then slowly remove the Radiator Fill Cap (7) from
the radiator. If coolant is not visible at the bottom of the fi ller neck, add a mixture of half water and half automotive type anti-freeze.
WARNING!
Do not remove the radiator cap when the engine is hot.
Every 100 hours, use compressed air (maximum pressure 100 psi) to blow dust from the radiator and oil cooler.
PARKING BRAKE LEVER ADJUSTMENT
The parking brake lever should be re-adjusted to where it fi rmly holds it's (locked park) setting with out easily being released.
Normal adjustment of the parking brake can be accomplished from the operator compartment. Turn the handle knob on the end of the lever clockwise (CW) to increase
the brake tension. Note: If the knob adjustment is inadequate to fi rmly hold its brake setting, this indicates the need to inspect the brake shoes and cables for excessive
wear and the need for service replacement.
