Use only MIL-H-5606 hydraulic fluid (red).
TIRES
Tire condition should be checked during pre-flight. If the tire tread is no longer visible, it should
be replaced. Inflate tires with compressed air.
Main Wheels - 24 ± 2 psi
Tail Wheel - 40 ± 10 psi
ENGINE LUBRICATION
Access to the oil filler port and dip stick is through the inspection door on the engine cowl. The
oil level should be checked prior to flight and oil added if below six quarts (5 quarts
— 7ECA).
Under normal operating conditions, the oil should be changed every 25 hours of operation (50
hours if a full flow oil filter is installed). A quick drain is provided on the engine sump with access
through the cooling duct below the engine cowl.
Use aviation grade oil with the proper viscosity as listed in Figure 7-1.
ENGINE AIR FILTER
The engine air filter should be inspected every 50 hours of normal operating or every 10 hours
under extremely dusty conditions. Clean with compressed air or replace as necessary.
CLEANING
EXTERIOR SURFACE
Wash with mild soap arid water. Avoid the use of harsh abrasives or detergents. Remove
grease and oil with solvent or non-leaded gas. The aircraft may be waxed if desired with a good
quality automotive wax.
Ice may be removed from the wings using a 50/50 solution of isopropyl alcohol and water. Do
not allow solution to come in contact with the plexiglass windows.
WINDSHIELD
The windshield and side windows should be cleaned with an aircraft windshield cleaner
following the manufacturer’s recommendations. If dust or dirt is present, rinse with water prior to
cleaning. The windshield can be waxed and polished with a soft cloth to fill minor scratches and
help protect against further scratching.
