NOTE: See description of numbered items in 2006 REV Series Op-
erator’s Guide (P/N 520 000 547) except for the following.
1) Brake/Parking Brake Pilot Lamp (Red)
This pilot lamp is disabled (does not light up) on the MX Z X 440.
WARNING
Make sure parking brake is fully disengaged before operating
the snowmobile.
When you ride the vehicle, brake that are caused to drag by
a continuous pressure on the lever may cause damage to the
brake system and cause loss of braking capacity and/or fire.
__________________________ 5

12) Tether Cord Cut-Out System
General
The tether cord cut-out system prevents snowmobile to runaway, if
the operator accidently falls off, by shutting off the engine.
WARNING
Always disconnect tether cord when leaving vehicle unattend-
ed and keep in a secured location.
Operation
Attach tether cord to clothing eyelet then snap tether cord cap over
post before starting engine.
To stop engine, completely pull cap from post.

Racing Application Only
NOTE: This switch is disabled (not operative) on vehicles modified
forwarrantyvalidation. Torunenginewith91octanenumberfuel

this switch must be disabled.

2. Button released: 108 (R + M)/2+ octane timing curve for North America
version (98 RON + Octane timing curve for outside North America)
After starting the engine, push and hold the pre-heat switch button
in order to pre-heat the tuned pipe. Release pre-heat switch button
once the tuned is pre-heated.
44) Primer Button
Pull and push button. It is not necessary when engine is warm.
To prime, activate button until a pumping resistance is felt. From
this point, pump 2 or 3 times to inject fuel in intake manifold. After
priming, ensure that primer button is pushed back.
NOTE: In very cold temperature, it is recommended to rotate primer
button 3-4 turns prior to pull it. This will eliminate the possibility of
sticking.

RECOMMENDED FUEL AND OIL
Fuel
Vehicles with Valid Warranty (Pre-Heat Switch Disabled)
Use premium unleaded gasoline, available from most service
stations or oxygenated fuel containing a maximum total of 10%
of ethanol or methanol or both. The gasoline used must have the
following recommended minimum octane number.
LOCATION OCTANE NUMBER
Inside North America 91 (RON + MON)/2
Outside North America 95 RON
Vehicles without Warranty (Pre-Heat Switch Enabled)
Use racing fuel with the following octane number.
MINIMUM
LOCATION OCTANE NUMBER
Inside North America 108 (RON + MON)/2
Outside North America 113 RON
RECOMMENDED
LOCATION OCTANE NUMBER
Inside North America 114 (RON + MON)/2
Outside North America 119 RON
NOTE: The fuel tank cap specifies an octane number of 91 as a min-
imum. A higher octane number is required in racing application.
All Vehicles
CAUTION: Never experiment with other fuels. The use of unrec-
ommended fuel can result in snowmobile performance deterio-
ration and damage to critical parts in the fuel system and engine
components.
__________________________ 9

WARNING
Always stop engine before refueling. Open cap slowly. If a dif-
ferential pressure condition is noticed (whistling sound heard
when loosening fuel tank cap) have vehicle inspected and/or
repaired before further operation. Fuel is flammable and ex-
plosive under certain conditions. Never use an open flame to
check fuel level. Never smoke or allow flame or spark in vicin-
ity. Always work in a well-ventilated area. Never top up the
fuel tank before placing the vehicle in a warm area. As tem-
perature increases, fuel expands and may overflow. Always
wipe off any fuel spillage from the vehicle.
Fuel System Antifreeze
When using oxygenated fuel, additional gas line antifreeze or water
absorbing additives are not required and should be not used.
When using non-oxygenated fuel, we highly recommend the use of
isopropyl base gas line antifreeze in a proportion of 150 mL (5 U.S. oz)
of gas line antifreeze added to 40 liters (10-1/2 U.S. gal) of gas.
This precaution is in order to reduce the risk of frozen carburetors
which may lead, in certain cases, to high fuel consumption or severe
damage to engine.
IMPORTANT: Use only methyl hydrate free gas line antifreeze.
Oil
NOTE: Premix fuel/oil ratio is 33:1
CAUTION: Never experiment with other fuel/oil ratios. Use only
oil that can flow at - 40°C (- 40°F).
Oil must be mixed with fuel at the ratio of 33:1 in a jerrycan then,
be poured in the fuel tank. Refer to chart below as a guideline to
properly premix oil with fuel.
Use only two-stroke engine injection oil, sold by authorized SKI-DOO
dealers.
MODEL OIL TYPE
MX Z X 440 XP-S synthetic 2-stroke oil (1)
(P/N 293 600 045) (12 x 1 L)
10 _________________________

CAUTION: (1) The XP-S synthetic 2-stroke oil is specially formu-
lated and tested for the severe requirements of the 453 engine.
Use of any other brand two-stroke oil may void the limited war-
ranty. Use only XP-S synthetic 2-stroke oil. There is no known
equivalent on the market for the moment. If a high quality equiv-
alent were available, it could be used.
The XP-S synthetic 2-stroke oil provides superior lubrication,
reduced engine component wear and oil deposit, thus maintaining
maximum-level performance and antifriction properties. This syn-
thetic injection oil meets the latest ASTM and JASO standards by
ensuring high biodegradability and low exhaust smoke.
CAUTION: Never use four-stroke petroleum or synthetic motor
oil and never mix these with outboard motor oil. Do not use
NMMA TC-W, TC-W2 or TC-W3 outboard two-stroke engine oils
or ashless two-stroke engine oils. Avoid mixing different brands
of API TC oil as resulting chemical reactions may cause severe
engine damage.
WARNING
Wipe off any oil spills. Oil is highly flammable.
PREMIX FUEL/OIL RATIO
33:1
METRIC (SI): 1 L of oil + 33 L of fuel = 33/1
IMPERIAL: 35 imp. oz of oil + 7.2 imp. gal of fuel = 33/1
1 L of oil + 7.2 imp. gal of fuel = 33/1
UNITED STATES: 34 U.S. oz of oil + 8.8 U.S. gal of fuel = 33/1
1 L of oil + 8.8 U.S. of fuel = 33/1

OPERATING INSTRUCTIONS
Engine Starting Procedure
•Re-check throttle control lever operation.
•Ensure that the emergency cut-out switch is in the ON position.
•Ensurethetethercut-outcapisinpositionandthatthecordis
attached to your clothing.
•To prime, activate button until a pumping resistance is felt. From
this point, pump 2 or 3 times to inject fuel in intake manifold.
After priming, ensure that primer button is pushed back.
NOTE: In very cold temperature, it is recommended to rotate primer
button 3 - 4 turns prior to pull it. This will eliminate the possibility of
sticking.
NOTE: Priming is not necessary when engine is warm.
Suspensions Adjustments
NOTE: There is no rear shock motion ratio adjustment on the
MX Z X 440.
In addition to all suspension adjustments described in REV Series
Operator’s Guide, take note of the 2 following points.
Shocks
All 4 shocks feature 2 adjustments.
Low Speed Compression Adjuster
The low speed adjuster modifies the damping force for small suspen-
sion velocities —less than 0.75 m/s (2.5 ft/s). It tunes the vehicle
for braking, cornering, hole shot and all the bumps that create low
speed movement in the suspension. This adjuster has 4 turns of
adjustment. Use a flat screwdriver to adjust it. Turning it clockwise
increases shock damping action (stiffer) for these low compression
speeds.
High Speed Compression Adjuster
The High speed adjuster modifies the damping force for high sus-
pension velocities —more than 0.5 m/s (1.6 ft/s). It tunes the ve-
hicle for hoops or bumps that create high speed movement in the
suspension. This adjuster has 3 turns of adjustment. Use a 17 mm
wrench to adjust it. Turning it clockwise increases shock damping
action (stiffer) for these high compression speeds.

Center and Front Springs
CAUTION: Make sure that center spring and both front springs
are still preloaded when front of vehicle is off the ground. Max-
imum spring preload is 25 mm (1 in). Otherwise, spring will be
coil bound when fully compressed.
