b. Soiled upholstery, except leather, may be cleaned by using an approved air drying type cleaner or foam
upholstery cleaner. Carefully follow the manufacturer's instructions. Avoid soaking or harsh rubbing.
c. Leather material should be cleaned with saddle soap or mild soap and water.

CLEANING CARPETS: Use a small whisk broom or vacuum to remove dirt. For soiled spots, use a
non-inflammable dry-cleaning fluid.

INTRODUCTION TO SERVICING: (Refer to Figure 2-8.) Servicing the airplane includes the
r e p l e nishment of fuel, oil, hydraulic brake fluid, tire pressures, lubrication requirements and other required
items.

LANDING GEAR SYSTEM.
2-32.
SERVICING LANDING GEAR: The landing gear consists of tires, brakes and oleo strut assemblies.
These should be inspected for proper gear extension, scored piston tubes, possible hydraulic fluid leakage,
security, and condition of all connection points. Check the brake linings for wear and frayed edges, and brake
discs for scoring. Replace if found necessary. Minor servicing is described in the following paragraphs, and for
detailed service and overhaul instructions, refer to Section VII.
2-33.
OLEO STRUTS.
2-34.
SERVICING OLEO STRUTS: Air-oil struts are incorporated in each landing gear oleo to absorb the
shock resulting from the impact of the wheels on the runway during landing. To obtain proper oleo action, the
nose gear oleo strut must have approximately 3.25 ± .25 inches of piston tube exposed, while the main gear
struts require approximately 4.50 ± .50 inches of tube exposure.
These measurements are taken with the airplane setting on a level surface under normal static load
(empty weight of airplane plus full fuel and oil). If the strut has less tube exposed than that prescribed, deter-
mine whether it needs air or oil by raising the airplane on jacks. With the strut extended, remove the cap from
the air valve at the top of the housing and depress the valve core to allow air to escape from the strut piston
until it is fully compressed. Allow the foam from the air-oil mixture to settle and then determine if oil is visible
up to the bottom of the filler plug hole. If oil is visible at the bottom of the hole, then all that is required is the
valve be checked for unsatisfactory conditions and air added as described in Paragraph 2-37. Should fluid be at
any level below the bottom of the filler plug hole, the oleo should be checked for leaks, etc., and oil added as
described in Paragraph 2-35 for the nose gear, or Paragraph 2-36 for the main gear. For repair procedures of
the landing gear and/or oleo struts, refer to Section VII.
Do not release air by removing the strut valve core or filler
plug. Depress the valve core pin until strut chamber pressure
has diminished.
Dirt and foreign particles form around the filler plugs of the
landing gear struts, therefore, before attempting to remove
these plugs, the tops of the struts should be cleaned with com -
pressed air and/or with a quick drying solvent.

CAUTION
Do not exceed these tube exposures.
