Carbon monoxide
If you need to keep the engine running while working on the vehicle, please ensure that you do so in
an open or very well ventilated area. Never run the engine in an enclosed area. If you do work in an
enclosed area, make sure to use a fume extraction system.

Fuel
CAUTION
FUEL USED TO DRIVE EXPLOSION ENGINES IS HIGHLY INFLAMMABLE AND CAN BECOME
EXPLOSIVE UNDER SPECIFIC CONDITIONS. IT IS THEREFORE RECOMMENDED TO CARRY
OUT REFUELLING AND MAINTENANCE PROCEDURES IN A VENTILATED AREA WITH THE EN-
GINE SWITCHED OFF. DO NOT SMOKE DURING REFUELLING OR NEAR FUEL VAPOUR. AVOID
ANY CONTACT WITH NAKED FLAME, SPARKS OR OTHER HEAT SOURCES WHICH MAY
CAUSE IGNITION OR EXPLOSION.
DO NOT ALLOW FUEL TO DISPERSE INTO THE ENVIRONMENT.
KEEP OUT OF THE REACH OF CHILDREN.
Hot parts
The engine and the exhaust system components get very hot and remain in this condition for a certain
time interval after the engine has been switched off. Before handling these components, make sure that
you are wearing insulating gloves or wait until the engine and the exhaust system have cooled down.
Coolant
The coolant contains ethylene glycol which, under certain conditions, can become flammable.
When it burns, ethylene glycol produces an invisible flame which however can cause burns.
CAUTION
TAKE PARTICULAR CARE NOT TO SPILL COOLANT ONTO HOT PARTS OR THE ENGINE AND
EXHAUST SYSTEM; THE FLUID MAY CATCH FIRE AND BURN WITH INVISIBLE FLAMES. WHEN
CARRYING OUT MAINTENANCE OPERATIONS, IT IS ADVISABLE TO WEAR LATEX GLOVES.
WHILE POISONOUS, COOLANT HAS A SWEET TASTE WHICH MAKES IT EXTREMELY AP-
PEALING TO ANIMALS. NEVER LEAVE COOLANT IN OPEN CONTAINERS WHERE IT MAY BE
REACHED AND DRUNK BY AN ANIMAL.

THE BRAKE FLUID MAY DAMAGE PAINTED, PVC OR RUBBER SURFACES. WHEN SERVICING
THE BRAKING SYSTEM, PROTECT THESE COMPONENTS WITH A CLEAN CLOTH. ALWAYS
WEAR PROTECTIVE GOGGLES WHEN SERVICING THE BRAKING SYSTEM. THE BRAKE FLUID
IS EXTREMELY DANGEROUS TO THE EYES. IN THE EVENT OF ACCIDENTAL CONTACT WITH
THE EYES, RINSE THEM IMMEDIATELY WITH PLENTY OF COLD, CLEAN WATER AND SEEK
MEDICAL ADVICE.
KEEP OUT OF THE REACH OF CHILDREN.
Battery electrolyte and hydrogen gas
CAUTION
THE BATTERY ELECTROLYTE IS TOXIC, CORROSIVE AND AS IT CONTAINS SULPHURIC ACID,
IT CAN CAUSE BURNS WHEN IN CONTACT WITH THE SKIN. WHEN HANDLING BATTERY
ELECTROLYTE, WEAR TIGHT-FITTING GLOVES AND PROTECTIVE APPAREL. IN THE EVENT
OF SKIN CONTACT WITH THE ELECTROLYTIC FLUID, RINSE WELL WITH PLENTY OF CLEAN
WATER. IT IS PARTICULARLY IMPORTANT TO PROTECT YOUR EYES BECAUSE EVEN TINY

Maintenance rules
GENERAL PRECAUTIONS AND INFORMATION
When repairs, disassembly and reassembly of the vehicle is carried out, follow the following recom-
mendations strictly.
BEFORE DISASSEMBLING COMPONENTS
Characteristics TUONO V4 R a-PRC ABS
CHAR - 8

•Remove the dirt, mud, dust and foreign objects from the vehicle before disassembling com-
ponents. Wherever required, use the special tools designed for this vehicle.
DISASSEMBLING COMPONENTS
•Do not loosen and/or tighten the screws and nuts using pliers or other tools, but always use
the specific wrench.
•Mark the positions on all the connection joints (hoses, cables, etc.) before separating them
and identify them with different distinctive marks.
•Each piece should be clearly marked in order to be identified during the installation phase.
•Carefully clean and wash the disassembled components with detergents with a low flam-
mability grade.
•Keep the coupled parts together because they have "adapted" to one another following
normal wear.
•Some components must be used together or replaced entirely.
•Keep away from heat sources.
REASSEMBLING COMPONENTS
CAUTION
BEARINGS MUST ROTATE FREELY, WITHOUT JAMMING AND/OR NOISE, OTHERWISE, THEY
NEED TO BE REPLACED.
•Only use ORIGINAL Aprilia SPARE PARTS.
•Comply with lubricant and consumables use guidelines.
•Lubricate parts (whenever possible) before reassembling them.
•Whentighteningnuts andscrews,start eitherfrom thecomponentswith thelargestdiameter
or from the innermost components, proceeding diagonally. Tighten nuts and screws in suc-
cessive steps before applying the tightening torque.
•Always replace self-locking nuts, washers, sealing rings, circlips, O-rings (OR), cotter pins
and screws with new parts if the thread is damaged.
•When assembling the bearings, make sure to lubricate them well.
•Check that each component is assembled correctly.
•After a repair or routine maintenance, carry out pre-ride checks and test the vehicle on
private grounds or in an area with low traffic.
•Clean all mating surfaces, oil seal rims and gaskets before refitting. Smear a thin layer of
lithium-based grease on the oil seal rims. Reassemble oil seals and bearings with the brand
or batch number facing outward (visible side).
ELECTRICAL CONNECTORS
Electric connectors must be disconnected as described below; failure to comply with this procedure
causes irreparable damage to both the connector and the wiring harness:
Press the relative safety clips, if applicable.
TUONO V4 R a-PRC ABS Characteristics
CHAR - 9

•Grip the two connectors and disconnect them by pulling them in opposite directions.
•If any signs of dirt, rust, moisture, etc. are noted, clean the inside of the connector carefully
with a jet of compressed air.
•Ensure that the cables are correctly fastened to the internal connector terminals.
•Then connect the two connectors, ensuring that they couple correctly (if fitted with clips, you
will hear them "click" into place).
CAUTION
DO NOT DISCONNECT CONNECTORS BY PULLING THE CABLES.
NOTE
THE TWO CONNECTORS CAN ONLY BE CONNECTED IN ONE DIRECTION: CONNECT THEM
THE RIGHT WAY ROUND.
TIGHTENING TORQUES
CAUTION
IF UNSCREWING A SELF-LOCKING NUT, IT MUST BE REPLACED WITH A NEW ONE.
CAUTION
REMEMBER THAT THE TIGHTENING TORQUE FOR ALL THE FIXING ELEMENTS LOCATED ON
WHEELS, BRAKES, WHEEL AXLES AND OTHER SUSPENSION COMPONENTS PLAY A FUN-
DAMENTAL ROLE IN GUARANTEEING THE SAFETY OF THE VEHICLE AND MUST BE KEPT AT
THE PRESCRIBED VALUES. REGULARLY CHECK THE TIGHTENING TORQUE OF THE FIXING
ELEMENTS AND ALWAYS USE A TORQUE WRENCH WHEN REFITTING. IF THESE WARNINGS
ARE NOT OBSERVED, ONE OF THESE COMPONENTS COULD LOOSEN AND COME OFF,
BLOCKING A WHEEL OR CAUSING OTHER PROBLEMS THAT WOULD COMPROMISE MA-
NOEUVRABILITY, LEADING TO A CRASH WITH THE RISK OF SERIOUS INJURY OR EVEN
DEATH.
Running-in
Runningthe engine in correctly isessential forensuring enginelongevity andfunctionality. Twistyroads
and gradients are ideal for running in the engine, brakes and suspension effectively. Vary your riding
speed during the running in period. This ensures that components operate in "loaded" conditions and
then "unloaded" conditions, allowing the engine components to cool.
CAUTION
THE FULL PERFORMANCE OF THE VEHICLE IS ONLY AVAILABLE AFTER THE SERVICE AT
THE END OF THE RUNNING IN PERIOD.
Follow the guidelines detailed below:
•Do not twist the throttle grip abruptly and completely when the engine is working at a low
revs, either during or after run-in.
•During the first 100 Km (62 miles) use the brakes gently, avoiding sudden or prolonged
braking. That is to permit the adequate adjustment of the pad friction material to the brake
discs.
•It is recommended, during the first 1000 km (621 mi), not to exceed 7500 rpm and 9500 rpm
up 2000 km (1243 mi).
AFTER THE SPECIFIED MILEAGE, TAKE YOUR VEHICLE TO AN Official Aprilia Dealer FOR THE
CHECKS INDICATED IN THE "RECOMMENDED PRODUCTS" TABLE IN THE SCHEDULED MAIN-
