Step 1. Pre-Start Check
Refer to the Pilot's Operating Handbook (POH) and complete a Pre-Flight Test before starting the
engine.
NOTICE: Examine the air filters every other flight for dirt and be prepared to clean or replace
them if necessary.
If the aircraft is flown in dusty conditions, more frequent oil changes and air filter replacements are
recommended. Install dust covers over openings in the cowling for additional protection. Refer to the
section "Volcanic Ash" in the "Engine Conditions" chapter in this manual.
NOTICE: Refer to the "Pilot Controls and Annunciators" chapter in this manual for dashboard
controls.
Step 2. Engine Start
WARNING MAKE SURE THAT THE AREA IN THE ROTATIONAL ARC RADIUS OF
THE PROPELLER IS CLEAR OF PERSONNEL OR ANY OBSTRUCTION
BEFORE STARTING THE ENGINE.
NOTICE: If the engine is to be started in an environment at temperatures less than 10°F (-12°C),
refer to the section "Apply Heat to a Cold Engine" in the "Engine Conditions" chapter
in this manual. This engine has a fuel vapor return. The fuel rail operates at high
pressure which makes the engine easier to start in hot weather. If the engine is to be
operated in an environment at temperatures above 100°F (38°C), refer to the section
"Engine Operation in Hot Weather" in the "Engine Conditions" chapter in this manual.
NOTICE: The following is Lycoming Engine's recommended start procedure. If there is any
variation between the start procedure in the aircraft manufacturer's POH and Lycoming
Engines' recommended start procedure, follow the aircraft manufacturer's procedure.
1. Complete specified steps and settings for engine start recommended by the aircraft POH or
aircraft manufacturer.
2. Examine the engine for hydraulic lock which is a condition where fluid accumulates in the
induction system or the cylinder assembly. Refer to Chapter 05-50 of the TEO-540-A1A
Engine Maintenance Manual for details.
