CAUTION
POTENTIAL HAZARD
•
If you leave the wire on the spark plug, someone could start the engine.
WHAT CAN HAPPEN
•
Accidental starting of engine could seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
•
Pull the wire off of the spark plug before you do any maintenance. Also, push it aside so it
does not accidentally contact the spark plug.
Adjusting the Control Cable
Periodically check the control cable for proper
adjustment.
1. Stop the engine and wait for all moving parts to stop.
2. Move the control bar back toward the handle to
remove the slack in the cable.
3. Ensure that a 1/16 to 1/8 in. (0.16 to 0.32 cm) gap
exists between the control bar bracket and the handle
(Refer to the inset in Fig. 6). To adjust the cable, go to
step 4.
Note: The control cable must have slack in the
disengaged position.
4. Adjust the cable as follows:
A. Unhook the spring end from the top hole in the
control bar bracket.
B. Slide the spring cover off the cable to expose the
cable adjuster.
C. Unhook the Z fitting from the cable adjuster
(Fig. 5) and position the Z fitting in a higher or
lower hole on the adjuster to obtain a proper gap of
1/16 to 1/8 in. (0.16 to 0.32 cm).
D. Install the spring cover over the cable adjuster and
the spring.
E. Hook the spring into the top hole of the control bar
bracket (Fig. 6).
Emptying the Fuel Tank
1. Stop the engine, wait for all moving parts to stop, and
remove the key from the switch.
2. Remove the cap from the fuel tank and use a
pump-type syphon to drain the fuel into a clean,
approved gasoline container.
3. After draining the fuel, start the engine and allow it to
run until it consumes all the fuel in the fuel tank and
stops running. Repeat this step two more times to
ensure that the fuel tank is empty.
