HYDRAULIC OIL
Unlatch and swing open the Oil Reservoir / Fuel tank Cover (20). Remove the reservoir cap to check the oil level. The hydraulic oil level should
be half way up the screen fi lter inside the fi ller neck of the reservoir. Add SAE 10W30 motor oil if it is below this level. Change the oil if major
contamination from a mechanical failure occurs.
ENGINE OIL
Check the engine oil level before every use. The machine should be parked on a level surface and the engine cool. Change the engine oil after
the fi rst 30 hours of operation and every 150 hours after that. The oil fi lter should be replaced with every oil change. The type of oil used depends
on the air temperature where the machine is used.
TEMPERATURE RANGE OIL WEIGHT
Above 60° F (15° C) SAE 10W-30
Below 60° F (15° C) SAE 5W-30
ENGINE COOLANT
Open the Engine Compartment Cover (1) and observe the coolant level in the Coolant Recovery Tank (22). If the level is low, add a mixture of half
water and half automotive type anti-freeze.
CAUTION!
Do not remove the Radiator Cap (23) when the engine is hot.
ENGINE AIR FILTER
Check the Engine Air Filter Service Indicator (24) before each use of the machine. Do not service the air fi lter unless the red fl ag is visible in the
service indicator. NOTE: After cleaning or replacing the engine air fi lter, the service indicator can be reset by pressing the end of the indicator.
CAUTION!
When servicing the engine air fi lter elements, use extreme care to prevent loose dust from entering the engine. Dust can severely
damage the engine.
The engine air fi lter contains a Primary (outer) and a Safety (inner) fi lter element. The Primary Element may be cleaned twice before being
replaced. The Safety Element should be replaced every third time that the Primary Filter Element is replaced. Never attempt to clean the Inner
Safety Element.
To clean the Primary Filter Element, unsnap the 2 clips at the end of the air fi lter and remove the end housing. Pull the primary element out. 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.
