Maintenance
a)
Transport
Trikes should preferably be transported on light trailers. Transporting the trike on a roof rack or
in a van requires disassembling the rear undercarriage.
b)
Storage
The trike unit should be thoroughly checked and cleaned prior to storage. After cleaning, wipe
all components with a clean lightly oiled cloth, while avoiding joints and rubberized parts.
If the trike unit is to be stored for a long period (e.g.:2-3 months):
•
Place a well oiled cloth in the open end of the exhaust (leave it in evidence).
•
Cover the air inlet filter with several layers of protection to prevent condensation.
•
Drain the fuel tank.
c)
Running in
Your trike's engine has been factory-tested but requires running-in.
The engine should be run in on the ground as stated in the ROTAX instruction manual. Liquid-
cooled engines equipped with a radiator placed under the keel of the trike should be switched
off when the water temperature reaches 185° F (85°C) to cool down. We recommend running in
these engines in flight with no passengers, adhering as closely as possible to the ROTAX
instructions. Except for take-off, avoid using full power for long periods during the first twenty-
five hours. After this period change engine oil and filter and make a general check of the engine
of first ten hours and tighten the bolts of the cylinder head.
d)
Pitch of the propeller
The pitch of the ARPLAST propeller can be adjusted according to the wing used and the air
density. A maximum ground speed of 5400 rpm is recommended for all the wings, except for
the iXess which needs a maximum of 5200 rpm in order to prevent over-revving at full speed.
Use the special tool and the Arplast manual to modify the pitch.
e)
Long storage
It is recommended to dismantle the trike sail in case of a long storage for several months. Fold
it properly, in respect with its manual, to loosen the tensions and to protect it from ultraviolet.
For the trike, you only need to place a cover or a sheet upon it and to prepare the engine
according to the Rotax user's manual. Reverse the operation to use it and make a single-seater
local flight test before using the aircraft as usual.
f)
Maintenance
For the maintenance of your engine, consult the Rotax manual
.
NEVER FLY USING AN UNBALANCED
PROPELLER
(due to a shock or any projection).
Vibrations generated will damage the reduction gear and the trike frame. To check propeller
balance: Remove the propeller and hang it, free to rotate (see your dealer), by the hub center. If
unbalanced, it should be returned to the factory for repair.
Frequently clean the radiator grill of the air inlet as well as the radiator cooling box (for
liquid cooled engine), in order to avoid obstruction due to grass or debris.
