INTRODUCTION
When performing maintenance, the safety must be always considered. Always use
proper personal protective equipment, at least but not limited to:
•Wear protective gloves when handling with chemicals and sealants.
Do not use protective hand creams as they can contaminate the sealants
and surfaces.
•Wear goggles, safety glasses or face shield for eye protection.
•Do not wear loose clothing and secure long hair to prevent them
from becoming tangled in power tools.
•Wear ear plugs or muffs to protect your ears.
•Wear suitable protective shoes with non-slip soles.
Prior to performing maintenance or repair consider following general rules:
•Check that emergency parachute system actuator is locked.
•Check that MASTER SWITCH and IGNITION is set OFF.
•Disconnect the negative terminal from the battery.
•Remove all jewellery. It can conduct electricity and may cause a short
circuit or can be caught in rotating tools.
•When working with the fuel and fuel system, always work in a well-
ventilated place. Always ground the airframe during fueling/defueling
to avoid risk of fire due to static discharge. Do not manipulate with open
flame and keep all ignition sources away.
•When working with a landing gear, properly support the aircraft with jacks.
Do not work under aircraft unless it is properly supported.
•While the engine is running, keep away from the propeller.
