Electric starter plug-in

Note:

To use the electric starter, connect a power

cord to the electric starter plug-in first and then to a
power outlet. 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
using the machine. If the cord is damaged,
do not operate the machine. Replace or repair
the damaged cord immediately. Contact an
Authorized Service Dealer for assistance.

Important:

To prevent damaging the electric

starter, run it in short cycles (5 seconds maximum,
then wait one minute before trying to start it
again). If the engine still does not start, take
the machine to an Authorized Service Dealer for
service.

8.

Disconnect the power cord from the power outlet first
and then from the machine (electric start only).

9.

Allow the engine to warm up for several minutes, move
the choke toward the Run position. Wait for the engine
to run smoothly before each choke adjustment.

CAUTION

If you leave the machine plugged into a
power outlet, someone can inadvertently start
the machine and injure people or damage
property.

Unplug the power cord whenever you are not
starting the machine.

Stopping the Engine

1.

Move the throttle to the Slow position, and then to the
Stop position (Figure 26).

Figure 26

2.

Wait for all moving parts to stop before leaving the
operating position.

3.

Remove the ignition key.

4.

Close the fuel shutoff valve by rotating it clockwise
(Figure 27).

Figure 27

5.

Pull the recoil starter 3 or 4 times. This helps prevent
the recoil starter from freezing up.

Operating the Traction Drive

CAUTION

If the traction drive is not properly adjusted, the
machine may move in the direction opposite of
what you intended, causing injury and/or property
damage.

Carefully check the traction drive and adjust it
properly, if necessary; refer to Checking the Traction
Drive Operation in Setup for more information.

Important:

If the machine moves when the traction

lever is in the released position, check the traction cable
(refer to Checking and Adjusting the Traction Cable) or
