2009 Can-Am DS 450 / DS 450 X CE ATV Operator's Guide (P/N 219 000 590)

This 2009 Can-Am Operator's Guide, P/N 219 000 590, covers the DS 450 and DS 450 X sport ATVs in CE configuration. Its scope is vehicle operation, owner maintenance, suspension adjustment, and basic troubleshooting; internal engine and transmission repair procedures are not included.

Text search and bookmarks: Main text is searchable, with bookmarks for the major sections. Some cover, label, and form text cannot be searched. The CE-declaration bookmark incorrectly opens the front cover.

• Engine lubrication and cooling: Oil/filter replacement, oil-tank strainer cleaning, coolant replacement, and radiator inspection, with the related fluid specifications.

• Air intake and exhaust: Air-filter and pre-filter servicing, airbox inspection, and muffler spark arrester removal, cleaning, and installation.

• Clutch and drive chain: Lever and clutch-cover adjustment, chain tensioning through the eccentric axle housing, and drive chain slider and sprocket inspection.

• HPG suspension: Front and rear preload, compression, and rebound adjustments, factory settings, and the DS 450 X front high-speed compression adjuster.

• Brakes and chassis: Brake-fluid reservoir checks, brake service limits, wheel removal and installation, and suspension inspection and lubrication.

• Electrical checks: Battery removal and installation, fuse identification, bulb replacement, headlight aiming, and troubleshooting with multifunction gauge warnings.

Written for vehicle owners and operators, this guide assigns basic maintenance to owners with the necessary mechanical skills and tools, while directing more demanding work to an authorized Can-Am dealer.

Engine Maintenance and Service Intervals

The Periodic Maintenance Chart separates owner tasks from dealer checks, including the throttle body, engine-management sensors, and steering column and bearing. The break-in oil/filter change and initial vehicle inspection are listed separately from recurring service.

The Rotax 449 uses dry-sump lubrication shared by the engine and wet-clutch transmission. The Oil Outlet Assembly illustration identifies the strainer, outlet fitting, and O-ring, supporting the oil-tank strainer cleaning procedure.

Clutch, Throttle Cable, and Chain Service

The clutch section distinguishes the DS 450 X quick cable adjuster from the standard locknut type. It also covers adjustment at the clutch cover using special tool P/N 529 035 081. An excessively tight adjustment can cause premature clutch-disc wear.

Throttle-cable lubrication includes access at the throttle body and use of cable luber P/N 529 035 738. The drive-chain section explains that gasoline or high-pressure washing can damage the chain's O-ring seals and lead to premature failure.

Suspension Settings and Brake Inspection

The Suspension Factory Settings views distinguish base and X-model front damping settings, helping owners choose the correct baseline before changing suspension setup.

Lubrication-point illustrations locate the A-arm and rear-linkage grease fittings. Inspection coverage extends to the swing arm, rear axle, and front wheel bearings; the brake section supplies pad and disc wear limits and front and rear reservoir illustrations.

Brake-fluid replacement and brake repair are assigned to an authorized Can-Am dealer. The guide warns against disassembling the pressurized shock absorbers.

Troubleshooting and Technical References

The Technical Guidelines address no-crank and no-start complaints, overheating, power loss, misfires, and poor shifting. The Multifunction Gauge Display Messages table distinguishes battery-voltage warnings, LIMP HOME, CHECK ENGINE, and NO ECM COMMUNICATION, helping identify the reported condition before arranging a repair.

Electronic fuel injection and the engine control module appear in specifications, fuse illustrations, and basic fault guidance. Detailed EFI/ECM diagnostic procedures and wiring diagrams are outside this guide's scope.

Component torque values, clutch and throttle adjustment data, fluid capacities, and a Conversion Chart support the included maintenance procedures. Vehicle Identification illustrations locate the VIN and engine-number labels.

English PDF and Included Pages

One printable, 152-page PDF in English: 147 numbered pages plus five unnumbered pages comprising the front and back covers, safety/copyright information, vehicle record, and EC-declaration notice. All five are included in the total; the actual EC Declaration of Conformity is not supplied.
