WALK-AROUNDWALK-AROUND

Maximum Performance andPrecise Control with HydrauMindTM

Komatsu’s smooth and precise HydrauMindTM system letsthe operator feel the performance of the machine. TheClosed Load Sensing System (CLSS) hydraulics aredesigned for both single and simultaneous movementswhich achieves unsurpassed controllability in thepositioning of the bucket.

Standard Universal AttachmentQuick CouplerA universal quick coupler enables commonattachments to be changed quickly and with littleeffort. Auxiliary hydraulics with flat faced connectorsare standard. Most competitors’ attachments can beutilized on Komatsu’s skid steer loaders.

Long Wheel BaseThe Komatsu SK815 skid steer loader has one of thelongest wheel bases in its class, 1041 mm 41", givingthe operator a more stable ride and a better platformfor operating high flow attachments.

Easy to use Travel and Loader PPC JoysticksLow effort Proportional Pressure Control (PPC) joysticks operate travel andloader operations. Easy to use PPC controls help operators of all skill levelswork precisely and efficiently all day long – with minimum effort andreduced operator fatigue.

Low Effort and FineHydraulic ControlThe 62 ltr 16.1 GPM auxiliary hydraulics can bemetered from 3.7 to 60 ltr.1 to 16 GPM or lockedinto continuous flow and the PPC pedal controlresults in low effort and fine control.

Enhanced Loader Arm andBucket ControlThe hydraulic self leveling (up only) bucket with1792 kg 3,950 lb breakout force enhances theproductivity of the operator on the job site. The45° dump and 30° rollback angles of the bucketallow for a faster dump cycle and load retentionover rough terrain.

Outstanding VisibilityWork with confidence and increased productivity.The standard top and rear shatter resistant windows,large side screen area as well as a superior view ofthe bucket, cutting edge and corners give theoperator an excellent 360° of job site visibility.

Optional "Super Flow"Auxiliary HydraulicsThe optional “Super Flow” auxiliary hydrauliccircuit enables the SK815 to utilize many high flowattachments. Cold planers, stump grinders, flailmowers and other attachments can be easilyoperated with the PPC joysticks.

Automatic Power Control "APC"Patented Komatsu anti-stall hydraulic system designed toallow full utilization of engine power. The operator can workwith full engine power during the toughest job siteapplications without worrying about engine stall outs.

Intelligent Operator ControlsKomatsu has enhanced operator productivity andefficiency with their technologically advanced operatorrestraint bar. The operator restraint bar incorporates aLCD gauge panel and warning light system which iseasily engaged and acts as a forearm rest. In addition,a Loader Arm Float Function control can be engagedon the joystick for enhanced back dragging orattachment applications.

Two-Speed TravelThis Komatsu exclusive, in this size class, allowsfor low impact shift-on-the-go speed changesbetween 10.5 kph 6.5 MPH work range and16 kph 10 MPH travel range. Improves load andcarry cycle times and travel times between jobsites.

Komatsu’s highly productive, innovativetechnology, environmentally friendlymachines built for the 21st century.

OPERATOR’SCOMPARTMENT

OPERATOR’SCOMPARTMENT

Effective Operator Cab EnvironmentAll instrumentation is within the peripheral view of the operator.The function switches are waterproof and placed within easyreach of the operator for comfort and convenience.

Superior Engine ControlThe engine RPM’s can be controlled by either thehand throttle, the foot accelerator, or incombination for tight work sites. The footaccelerator is not available with hand and footcontrol pattern.

Control Pattern ChangeValve Lever - OptionalConvert from the Komatsu pattern tothe optional pattern with the flip of alever. This allows the Komatsu skidsteer loader to be customized to meetthe individual operators needs.Especially useful for rental centers orwhenever different operators need touse the machine on the job site.

Enhanced OperatorSafetyThe operator restraint bar isergonomically designed to provideforearm support and restrains theoperator from unintentionally leaving theseat. The seat incorporates a safetyswitch which de-activates the travel andhydraulic circuits while activating thewet disc brakes when the operatorleaves the machine. A 76 mm 3'' seatbelt is provided as standard equipment.

Enhanced Operator ControlsThe gauge panel, warning and indicator lights aremounted on the operator restraint bar. Monitoringof all critical machine functions is easy, convenientand doesn’t distract the operator from the job athand. The control pattern is back lit to identifywhich pattern is in operation.

PPC Joystick ControlsAnother advanced feature is the loweffort Proportional Pressure Control(PPC) joysticks that operate travel andloader operations. Easy to use PPCcontrols help operators of all skill levelswork precisely and efficiently all daylong – with minimum effort andreduced operator fatigue.

Split Designed OperatorRestraint BarThe split designed operator restraint bar iseasily engaged from the left and right siderespectfully. The gauge panels and indicatorlights are incorporated into the restraint barfor enhanced operator efficiency, comfortand confidence.

Auxiliary HydraulicControlThe auxiliary hydraulic control providesexcellent hydraulic power to frontmounted hydraulic attachments. Thefoot pedal can be utilized with Komatsuor optional control pattern.

Tilt-ForwardROPS/FOPS, TopEngine Cover &Floor PlateThis patented feature allows thecab to tilt with the loader armsdown or up. Access to theengine, hydraulic and hydrostaticcomponents is easily achieved.

Hinged Top EngineCover and RearDoor PanelThe top engine opens out of theway for excellent engine accessand the hinged rear door allowsfor convenient daily service checks.

250 Hour PinGreasing IntervalMinimizes daily downtime, reducesowning and operating costs. Thespecial bronze bushings arespecially treated and accompaniedwith dust seals.

Removable PolyvinylFuel TankThe fuel tank is constructed ofpolyvinyl plastic, corrosion resistant,and guards against condensation. Alarge opening with a strainer allowsfor easy re-fueling and an externallevel indicator is visible to ensuresafety during re-fueling. The fueltank is easily removed with a fuelshut-off and quick release.

ORFS Fittings,O-Ring Face SealConnectorsSpecific torque settings are notrequired for optimal performance.The fitting and connectors have alow sensitivity to vibration and arereusable even after severaldisassembles.

Side By SideRadiator and OilCooler The radiator and oil cooler areaccessible for cleaning from eitherside and are tiltable for additionalinspection.

Loader ArmMaintenanceSupport StrutAllows the operator to engage ordisengage the maintenancesupport strut without leaving theoperator’s seat.
