Engine operation
Engine warm-up
1. Once the engine starts, allow it to warm up for 2 to 3 minutes
at idling (i.e. low speed).
2. Warming the engine helps to lubricate its internal workings
more smoothly. Allow the engine to warm up fully, especially
when it is cold.
Starting a warm engine
1. Move the ignition switch away from the Stop position.
2. Make sure that the throttle trigger is at the idle speed posi-
tion.
3. Check that the choke lever is in the "Run" position.
4. If fuel tank is not empty, pull on the starter grip to start the
engine.
5. If no fuel is visible in the purge bulb, alternately press and re-
lease the purge bulb until the fuel is sucked up into it.
6. Checking that the area around you is safe and pull on the
starter grip to start the engine.
Stopping the engine
1. Release the throttle trigger and set the engine to idling (i.e.
low speed).
2. Move the ignition switch to the Stop position.
3. In the event of an emergency, stop the engine immediately
using the ignition switch.
4. If the engine fails to stop, move the choke lever to the "Cold
Start" position. The engine will stall and come to a halt (a
choke stop).

If the engine fails to stop when the ignition switch is used, have
the ignition switch checked and repaired by your dealer before
you use the product again.
