Spark Plug(S); Throttle Cable Adjustment - Arctic Cat 2013 400 TRV Operator's Manual

7. Attach one clamp of the negative
(black) jumper cable to the negative (-)
terminal (3) of the good battery (B);
then attach the other clamp of the nega-
tive (black) jumper cable (4) to an
unpainted metal surface (A) on the
engine or frame well away from dead
battery and fuel system components.
! WARNING
Never make the final connection to a
battery as a spark could ignite hydro-
gen gases causing an explosion of
the battery resulting in acid burns or
blindness.
8. Stand well away from the dead bat-
tery and start the vehicle with the
good battery. Allow the vehicle to
run for several minutes applying
some charge to the dead battery.
9. Start the vehicle with the dead bat-
tery and allow it to run for several
minutes before disconnecting the
jumper cables.
10. Remove the jumper cables in oppo-
site order of hook-up (4, 3, 2, 1). Be
careful not to short cables against
bare metal.
 NOTE: Have the battery and elec-
trical system checked prior to
operating the vehicle again.

Spark Plug(s)

This ATV comes equipped with a specified
spark plug. See the specifications chart for
the correct spark plug. A light brown insu-
lator indicates that the plug is correct. A
white or dark insulator indicates that the
engine may need to be serviced or the car-
buretor (400) may need to be adjusted.
Consult an authorized Arctic Cat ATV
dealer if the plug insulator is not a light
brown color. To help prevent cold weather
fouling, make sure to thoroughly warm up
the engine before operating.
To maintain a hot, strong spark, keep the
plug free of carbon.
Before removing the spark plug, be sure
to clean the area around the spark plug. If
you do not, dirt could enter engine when
removing or installing the spark plug.

Adjust the gap to specification for proper
ignition (see appropriate specification
chart). Use a feeler gauge to check the gap.
When installing the spark plug, be sure to
tighten it securely. A new spark plug should
be tightened 1/2 turn once the washer con-
tacts the cylinder head. A used spark plug
should be tightened 1/8 - 1/4 turn once the
washer contacts the cylinder head.
Throttle Cable
Adjustment
To adjust the throttle cable free-play:
1. Loosen the jam nut from the throttle
cable adjuster.
2. Slide the rubber boot away and turn
the adjuster until the throttle lever
has proper free-play of 3-6 mm (1/8-
1/4 in.).
