Note: Remove your glove when you push in the
primer so that air cannot escape from the primer hole.
Important: Do not use the primer or the choke if
the engine has been running and is hot. Excessive
priming may flood the engine and prevent it from
starting.
4. Connect an extension cord to a power source and the
machine, and push the electric-start button (model
38459 only) (Figure 17), or pull the recoil start handle
(Figure 18).
Figure 17
Note: Use only a UL-listed, 16-gauge extension cord
recommended for outdoor use that is not longer than
50 feet (15 m).
WARNING
The electrical cord can become damaged,
causing a shock or fire.
Thoroughly inspect the electrical cord before
plugging it into a power source. If the
cord is damaged, do not use it to start the
machine. Replace or repair the damaged cord
immediately. Contact an Authorized Service
Dealer for assistance.
Important: Run the electric starter no more
than 10 times at intervals of 5 seconds on, then
5 seconds off. Running the electric starter
extensively can overheat and damage it. If the
engine does not start after this series of attempts,
wait at least 40 minutes to allow the starter to cool
before attempting to start it again. If the engine
does not start after the second series of attempts,
take the machine to an Authorized Service Dealer
for service (model 38459 only).
Note: If you pull the recoil handle and feel no
resistance, the starter may be frozen. Thaw out the
starter before attempting to start the machine.
5. While the engine is running, push in the choke lever
slowly.
6. Unplug the extension cord from the power source and
the machine (model 38459 only).
CAUTION
If you leave the machine plugged into a power
source, someone can inadvertently start the
machine and injure people or damage property
(model 38459 only).
Unplug the power cord whenever you are not
starting the machine.
