SERVICE STATION MANUAL

GRISO 850

This manual provides the main information to carry out regular maintenance operations on your vehicle.

This manual is intended to Moto Guzzi Dealers and their qualified mechanics; several concepts have

been deliberately omitted as they are considered unnecessary. As it is not possible to include complete

mechanical notions in this manual, users should have basic mechanical knowledge or minimum

knowledge about the procedures involved when repairing scooters. Without this knowledge, repairing or

checking the vehicle may be inefficient or even dangerous. As the vehicle repair and check procedures

are not described in detail, be extremely cautious so as not to damage components or injure individuals.

In order to optimise customer satisfaction when using our vehicles, Moto Guzzi s.p.a. commits itself to

continually improve its products and the relative documentation. The main technical modifications and

changes in repair procedures are communicated to all Moto Guzzi Sales Outlets and its International

Subsidiaries. These changes will be introduced in the subsequent editions of the manual. In case of

need or further queries on repair and check procedures, consult Moto Guzzi CUSTOMER

DEPARTMENT, which will be prepared to provide any information on the subject and any further

communications on updates and technical changes related to the vehicle.

NOTE Provides key information to make the procedure easier to understand and carry out.

CAUTION Refers to specific procedures to carry out for preventing damages to the vehicle.

WARNING Refers to specific procedures to carry out to prevent injuries to the repairer.

Personal safety Failure to completely observe these instructions will result in serious risk of personal

injury.

Maintenance rules

GENERAL PRECAUTIONS AND INFORMATION

When repairing, dismantling and reassembling the vehicle, follow the recommendations given below

carefully.

BEFORE DISASSEMBLING COMPONENTS

•Beforedismantling components, remove dirt, mud, dust and foreign bodies from the vehicle.

Use the special tools designed for this bike, as required.

COMPONENTS REMOVAL

•Donotloosenand/or tighten screws and nuts using pliers or any other tools than the specific

wrench.

•Mark positions on all connection joints (pipes, cables etc.) before separating them, and

identify them with distinctive symbols.

•Each component needs to be clearly marked to enable identification during reassembly.

•Clean and wash the dismantled components carefully using a low-flammability detergent.

•Keep mated parts together since they have "adjusted" to each other due to normal wear.

Characteristics GRISO 850

CHAR - 8

•Some components must be used together or replaced completely.

•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 Moto Guzzi SPARE PARTS.

•Comply with lubricant and consumables use guidelines.

•Lubricate parts (whenever possible) before reassembling them.

•When tightening nuts and screws, start from the ones with the largest section or from the

internal ones, moving diagonally. Tighten nuts and screws in successive steps before ap-

plying the tightening torque.

•Always replace self-locking nuts, washers, sealing rings, circlips, O-rings (OR), split pins

and screws with new ones if their tread 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 procedure, carry out pre-ride checks and test the ve-

hicle on private grounds or in an area with low traffic density.

•Clean all coupling surfaces, oil guard rims and gaskets before refitting them. Smear a light

layer of lithium-based grease on the oil guard rims. Reassemble oil guards and bearings

with the brand or lot 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.

•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

REMEMBERTHATTHETIGHTENING TORQUES FORALLFASTENINGELEMENTS ON WHEELS,

BRAKES, WHEEL AXLES AND ANY OTHER SUSPENSION COMPONENTS PLAY A KEY ROLE

IN ENSURING VEHICLE SAFETY AND MUST COMPLY WITH SPECIFIED VALUES. CHECK THE

GRISO 850 Characteristics

CHAR - 9

TIGHTENING TORQUES OF FASTENING ELEMENTS ON A REGULAR BASIS AND ALWAYS USE

A TORQUE WRENCH TO REASSEMBLE THESE COMPONENTS. FAILURE TO COMPLY WITH

THESE RECOMMENDATIONS MAY CAUSE ONE OF THESE COMPONENTS TO LOOSEN OR

EVEN DETACH, CAUSING A WHEEL TO LOCK OR COMPROMISING VEHICLE HANDLING. THIS

MAY LEAD TO FALLS, WITH THE RISK OF SERIOUS INJURY OR DEATH.

Running-in

Runningtheengineincorrectlyisessentialfor ensuring engine longevity and functionality. Twisty roads

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 CLUTCH MAY EMIT A SLIGHT BURNING SMELL WHEN FIRST USED. THIS PHENOMENON

SHOULD BE CONSIDERED NORMAL AND WILL DISAPPEAR AS SOON AS THE CLUTCH

PLATES GET ADAPTED.

ITISIMPORTANTTOSTRAIN ENGINE COMPONENTS DURINGRUN-IN,HOWEVER,MAKESURE

NOT TO OVERDO THIS.

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 fully open the throttle grip abruptly at low engine speeds, either during or after the

running in period.

•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.

AFTER THE SPECIFIED MILEAGE, TAKE THE VEHICLE TO AN OFFICIAL Moto Guzzi DEALER

FOR THE CHECKS INDICATED IN THE "AFTER RUN-IN" TABLE IN THE SCHEDULED MAINTE-

NANCE SECTION TO AVOID INJURING YOURSELF, OTHERS AND /OR DAMAGING THE VEHI-

CLE.
