Introduction
We would like to congratulate you on your purchase of a KTM motorcycle.
You are now owner of a sporty and modern motorcycle which you are bound to
have a great time with, provided you care for it properly. This manual will furnish
you with important information on how to operate and maintain your new KTM
motorcycle. At the time of printing, the handbook covered the most up-to-date
models in this series. It is, however, possible that we may have made slight modi-
fications in the meantime due to development in our motorcycle design.
Many motorcyclists have a good working knowledge of motorcycle mechanics; if
this is true in your case, you will be able to use this manual to carry out most of
the maintenance steps yourself. If, on the other hand, you are not very familiar
with motorcycles, it might be better to have a professional KTM dealer perform
those steps marked *described in the chapter entitled “Maintenance Work on
Chassis and Engine” of this manual.
Take special care to follow the recommended run in, inspection, and maintenance
intervals. Heeding these guidelines will significantly increase the life of your
motorcycle. Have services carried out by a KTM dealer so that your warranty
claim remains intact.
We wish you a lot of fun when driving !
KTM Austria’s certificate of achievement for its Quality System ISO 9001 is the
beginning of an on-going total re-engineering quality plan for a brighter tomorrow.

Engine number, engine type
Engine number and engine type are stamped into the engine housing
underneath the carburetor. Write this number into the box on page 1.
Clutch lever
The clutch lever 1is fitted on the left hand side of the handle bar. When
engine is cold, there should be a play of 10 mm (0.4 in) (measured at outer
edge). !
CAUTION
!
IF THERE IS NO PLAY ON THE CLUTCH LEVER, THE CLUTCH WILL START TO SLIP. THE
CLUTCH WILL THEN OVERHEAT, DESTROYING THE CLUTCH LININGS.
Choke lever
When the choke lever 2is pulled backwards, a bore is opened in the car-
buretor.which enables the engine to draw in additional fuel. This produces
a „rich“ fuel/air mixture necessary for cold start. When the choke lever is
pushed forward as far as it will go, the bore will be closed again. In this
position the choke cable must have a play of approx.2mm.
!
CAUTION
!
IF THERE IS NO PLAY IN THE CHOKE CABLE, THE BORE OF THE COLD STARTER SYSTEM
CANNOT BE COMPLETELY CLOSED. THIS RESULTS IN HIGH FUEL CONSUMPTION, THE
ENGINE RUNS UNEVENLY WITH EXTREME WEAR OF PISTON AND CYLINDER.

Fuel
This motorcycle is equipped with separate lubrication. This means that the
two-stroke oil required for engine lubrication is not admixed to the fuel but
contained in a separate oil tank (see below). An oil pump is used for con-
trolled admixing of two-stroke oil into the fuel in the carburetor.
Besides, the motorcycle is equipped with a catalytic converter. Therefore, it
is absolutely necessary to fill in unleaded fuel.
Fuel:
UNLEADED REGULAR GASOLINE WITH AT LEAST 91 OCTANES (RON)
Fuel expands when its temperature rises. Therefore do not fill the tank to
the top (see fig.). Fuel tank capacity 8.5 liter

WARNING

GASOLINE IS HIGHLY FLAMMABLE AND POISONOUS. EXTREME CAUTION SHOULD BE
USED WHEN HANDLING GASOLINE. DO NOT REFUEL THE MOTORCYCLE NEAR OPEN FLA-
MES OR BURNING CIGARETTES. ALWAYS SWITCH OFF THE ENGINE BEFORE REFUELLING.
BE CAREFUL NOT TO SPILL GASOLINE ON THE ENGINE OR EXHAUST PIPE WHILE THE
ENGINE IS HOT. WIPE UP SPILLS PROMPTLY. IF GASOLINE IS SWALLOWED OR SPLASHED
IN THE EYES, SEEK A DOCTOR’S ADVICE IMMEDIATELY.
!
CAUTION
!
NEVER FILL IN LEADED FUEL. LEADED FUEL WILL DESTROY THE CATALYTIC CONVERTER.
Fuel tap
OFF In this position the fuel tap is closed. No fuel may flow to the carbu-
retor.
ON When using the motorcycle, the twist grip must be set to the ON
position. Now fuel may flow to carburetor. In this position the tank
empties down to the fuel reserve of approx. 3 liters.
RES The reserve tank, approximately 3 liters, cannot be tapped until the
twist grip is turned to the RES position. Fill the tank as soon as possi-
ble and remember to turn the twist grip back to the ON position so
that you will have backup fuel next time, too.
!
CAUTION
!
THE FUEL TAP SHOULD BE LOCKED WHENEVER THE MOTORCYCLE IS PARKED. IF THE TAP
IS NOT CLOSED THE CARBURETOR MAY OVERFLOW AND FUEL GET INTO THE ENGINE.
NOTE:
That the fuel tank can completely be emptied this motorcycle has two fuel
taps.
Open both fuel taps before each start.
Close both fuel taps after each riding.
Oil tank
The oil tank 1is mounted on the right side in front of the fuel tank. Here,
the two-stroke oil for separate lubrication of the engine must be filled in.
The oil level can easily be checked through the transparent material of the
oil tank. Engine oil:
2-stroke engine oil suitable for a mixing ratio of 1:50
and for separate lubrication
KTM recommends SHELL ADVANCE VSX2
To open it:
pull vent hose out of the frame and turn closure cap counter-
clockwise.
To close it: apply closure cap and turn it clockwise. Stick vent hose into
frame and install it without kinks.
Tank volume: 1.3 liters

DRIVING INSTRUCTIONS
– Read the entire manual carefully before your first drive.
– Familiarize yourself with the operating elements.
– Adjust the foot brake pedal to the most comfortable positi-
ons for you.
– Get used to handling the motorcycle on an empty car park,
before starting on a longer drive. Also try to drive as slowly
as possible and in standing position, to improve your feeling
for the vehicle.
– Hold the handlebar with both hands and leave your feet on
the foot rests while driving.
– Remove your foot from the foot brake pedal when you are
not braking. If the foot brake pedal is not released the brake
pads rub continuously and the braking system is overheated.
– You may only be accompanied by a passenger if your
motorcycle is fitted and registered for such purposes. The
passenger must hold tight to the brackets or hold on to the
driver during the drive, with his feet on the passenger foot
rests.
– Do not make any alterations to the motorcycle and always
use ORIGINAL KTM SPARE PARTS. Spare parts from other
manufacturers can impair the safety of the motorcycle.
– Motorcycles are sensitive to alterations in the distribution of
weight. If you are taking luggage with you, this should be
secured as close as possible to the middle of the vehicle; dis-
tribute the weight evenly between the front and rear wheel.
Never exceed the maximum permissible laden weight and
the axle weights. The maximum permissible laden weight is
made up of the following components:
– Motorcycle ready for operation and tank full
– Luggage
–
Driver and passenger with protective clothing and helmet.
– Pay attention to running in instructions.
Running in
Even finely machined surfaces of engine parts have rougher
surfaces than parts that slide on each other for a long time.
Therefore, every engine must be run in. For this reason, do not
demand maximum performance from the engine for the first
1000 kilometers. The vehicle must be run in at low, changing
performance level for the first 1000 KM (620 miles). Maximum
rotational speeds during the first 1000 kilometers will have a
negative impact on the engine’s life.
Check the following before each start
When you start off, the motorcycle must be in a perfect tech-
nical condition. For safety reasons, you should make a habit of
performing an overall check of your motorcycle before each
start.
The following checks should be performed:
1 OIL LEVEL IN OIL TANK
Once there is no two-stroke oil in the oil tank, the engine is
bound to break down. The vent hose of the oil tank must
be installed without kinks.
2 GEAR OIL LEVEL
Insufficient amounts of oil in the transmission will lead to
premature wear and subsequently to transmission failure.
3 FUEL
Check that there is sufficient fuel in the tank.
4 CHAIN
A loose chain can fall off; an extremely worn chain can tear,
and insufficient lubrication can result in unnecessary wear to
the chain and rear sprockets.
5 TIRES
Check for damaged tires. Tires showing cuts or dents must
be replaced. The tread depth must comply with the legal
regulations. Also check the air pressure. Insufficient tread
and incorrect air pressure reduce the driving performance.
6 BRAKES
Check correct functioning of the braking system. Check for
sufficient brake fluid in the reservoir. If the level of brake
fluid falls below the minimum value, this indicates a leak in
the braking system or completely worn out brake pads.
Arrange for the braking system to be checked by a KTM
specialist garage, as complete failure of the braking system
can be expected.
Also check the state of the brake hoses and the thickness of
the brake linings. Brake linings measured at their thinnest
point should not be less than 1 mm since extremely worn
linings can lead to brake failure.
7 CABLES
Check correct setting and easy running of all control cables.
8 COOLING LIQUID
Check the level of cooling liquid when the engine is cold.
9 ELECTRICAL SYSTEM
Check correct functioning and adjustment of headlights,
parking light, tail-lights, brake lights, flashers, indicator
lamps, horn and emergency OFF switch while the engine is
running.
10LUGGAGE
If you are taking luggage with you, check that this is secu-
rely fastened.

SHORT TRIP. THE PROTECTIVE CLOTHING SHOULD BE BRIGHTLY
COLOURED SO THAT OTHER USERS OF THE ROADS CAN SEE YOU AS
EARLY AS POSSIBLE. YOUR PASSENGER OF COURSE WILL ALSO NEED
SUITABLE PROTECTIVE CLOTHING.
–D
O NOT DRIVE AFTER HAVING CONSUMED ALCOHOL.
–O
NLY USE ACCESSORIES THAT HAVE BEEN RELEASED BY KTM. FOR
EXAMPLE, FRONT PANELLING CAN IMPAIR THE DRIVING PROPERTIES OF
THE MOTORCYCLE. CASES, EXTRA TANKS ETC. CAN ALTER THE WEIGHT
DISTRIBUTION AND THUS ALSO IMPAIR THE VEHICLE’S DRIVING PRO-
PERTIES.
–T
HE FRONT AND REAR WHEEL ARE ONLY ALLOWED TO BE TIRED WITH
TIRES THAT HAVE THE SAME PROFILE TYPE.

CAUTION
!
–M
AXIMUM PERIOD FOR CONTINUOUS STARTING: 5 SECONDS. WAIT AT LEAST 5
SECONDS BEFORE TRYING AGAIN.
–DON’T RIDE YOUR MOTORCYCLE WITH FULL LOAD AND DON’T REV ENGINE WHEN
COLD. BECAUSE THE PISTON IS WARMING UP FASTER THAN THE WATER COOLED
CYLINDER, IT CAN CAUSE ENGINE DAMAGE. ALWAYS KEEP IN MIND THAT THE ENGINE
SHOULD BE WARMED UP WITH SMALL LOAD AT MEDIUM R.P.M.
IF THE ENGINE IS DOES NOT CRANK WHEN YOU ACTUATE THE STAR-
TER TIP SWITCH:
– Check if the ignition is on
– Check if the parking light and the cockpit lights are on.
– If this is not the case, the battery is discharged

THE STARTER TIP SWITCH:
– Check if the fuel tap is open
– Check if the emergency OFF switch is on
– Check if the choke lever has been operated
– Check if sufficient fuel is in the tank
– If this is not the case, refill the tank
– if sufficient fuel is in the tank, proceed as described in the „Trouble-
shooting“ section or contact a KTM dealer.
NOTE:
– When you turn on the ignition, you will hear a brief whirring sound.
While you hear this sound, a cleaning cycle of the control roller in the
cylinder is executed.
– Check if the oil level warning lamp works properly (see „Control
lamps“).

Shifting/Riding
You are now in first gear, refered to as the drive or uphill gear.
Depending on the conditions (traffic, road gradient, etc.), you
can shift to a higher gear. Close throttle, at the same time pull
clutch lever and shift to the next higher gear. Let clutch lever
go again and open throttle. If you turned on the choke, make
sure you turn it off again as soon as engine is warm.
When you reach full speed through turning the throttle grip all
the way, turn throttle back to 3/4; the speed hardly decreases
although the engine will use less gas. Never open the throttle
wider than the engine can handle. Excessive turning of the
throttle grip will increase full consumption.
By shifting down, use the brakes if necessary and close throttle
at the same time. Pull clutch lever and shift down to the next
gear. Let clutch lever go slowely and open throttle or shift
down again.
If the engine is killed f.ex. at a crossing, simply pull the clutch lever
and start. It is not necessary to switch the gear to NEUTRAL.

LOWER GEAR
. T HE ENGINE WILL OVERSPEED , DAMAGING THE VALVES .
I N ADDITION , THE REAR WHEEL BLOCKS SO THAT THE MOTORCYCLE
CAN EASILY GET OUT OF CONTROL
.
–IF DURING EXTENDED DOWNHILL RIDES THE ENGINE IS RUNNING
ALONG WITHOUT ANY ACTUATION OF THE THROTTLE, YOU HAVE TO
TURN UP THE THROTTLE A BIT ONCE IN A WHILE TO MAKE SURE THAT
ENOUGH ENGINE OIL IS FED TO THE ENGINE.
–I
F THE RED OIL LEVEL WARNING LAMP LIGHT UP, IT WILL BE NECESSARY
TO REFILL THE OIL TANK WITH TWO-STROKE ENGINE OIL DURING THE
NEXT 100 KILOMETERS (SEE PAGE 7).
–O
IL PUMP AND OIL LINES MUST BE BLED WHENEVER THE OIL TANK
WAS COMPLETELY EMPTIED (SEE BLEEDING THE OIL PUMP). OTHER-
WISE THE OIL PUMP WILL NOT DELIVER OIL, THUS CAUSING ENGINE
DAMAGE.
–IN THE EVENT THAT, WHILE RIDING ON YOUR MOTORCYCLE, YOU
NOTICE ANY UNUSUAL OPERATION-RELATED NOISE, STOP IMMEDIA-
TELY, TURN THE ENGINE OFF, AND CONTACT AN AUTHORIZED KTM
DEALER.
NOTE TO THE COOLING SYSTEM
If due to slow traffic in cities or waiting at a traffic light, for
example, little or no relative wind is blowing through the radia-
tors, it may happen that the cooling water temperature rises
and the red cooling liquid temperature warning lamp lights up
(appr. 110° C, 238° F). In this case, you should try to drive on
briskly, if possible, for generally the lamp will stop being lit
soon if enough relative wind gets into the radiators. However,
you should check the cooling liquid level later on after the
engine has cooled down again.
!
CAUTION
!
HOWEVER, IF THE RED COOLING-LIQUID TEMPERATURE WARNING LAMP
LIGHTS UP WHILE YOU ARE DRIVING ALONG BRISKLY, THIS WILL INDICATE
A DEFECT IN THE COOLING SYSTEM. IN THIS CASE, STOP IMMEDIATELY,
SINCE OTHERWISE YOU MAY DAMAGE YOUR ENGINE. LET YOUR ENGINE
COOL DOWN, CHECK THE COOLING SYSTEM FOR LEAKS, AND CHECK THE
COOLANT LEVEL. CAUTION - SCALDING HAZARD! DO NOT DRIVE
ON, UNTIL THERE IS SUFFICIENT LIQUID IN THE COOLING SYSTEM.

WARNING

IF THE RADIATOR CAP IS REMOVED WHEN THE ENGINE IS HOT, HOT COO-
LING LIQUID, THAT IS UNDER PRESSURE, CAN SPRAY OUT AND CAUSE
SEVERE BURNS.ALLOW YOUR ENGINE TO COOL DOWN AND, IN THE
MEANTIME, CHECK THE COOLING SYSTEM FOR LEAKS.
Braking
Close throttle and apply the hand and foot brakes at the same
time. When driving on sandy, wet or slippery ground use
mainly the rear wheel brake. Always brake with feeling,
blocking wheels can cause you to skid or fall. Also change
down to lower gears depending on your speed.

WARNING

WHEN YOU BRAKE, THE BRAKE DISCS, BRAKE PADS, BRAKE CALIPER AND
BRAKE FLUID HEAT UP. THE HOTTER THESE PARTS GET, THE WEAKER THE
BRAKING EFFECT
. I N EXTREME CASES , THE ENTIRE BRAKING SYSTEM CAN FAIL .
Stopping and parking
Apply the brakes fully and put the engine into neutral. To stop
the engine, switch off the ignition. Close fuel taps. Park on
solid ground and lock the vehicle.

WARNING

–NEVER LEAVE YOUR MOTORCYCLE WITHOUT SUPERVISION AS LONG AS
THE ENGINE IS RUNNING.
–MOTORCYCLE ENGINES PRODUCE A GREAT AMOUNT OF HEAT WHILE
RUNNING. THE ENGINE, THE RADIATORS, EXHAUST SYSTEM, MUFFLER,
BRAKE DISCS, AND SHOCK ABSORBERS CAN BECOME VERY HOT. DO
NOT TOUCH ANY OF THESE PARTS AFTER OPERATING THE MOTORCY-
CLE, AND TAKE CARE TO PARK IT WHERE PEDESTRIANS ARE NOT LIKELY
TO TOUCH IT AND GET BURNED.
–NEVER PARK YOUR MOTORCYCLE IN PLACES WHERE THERE EXIST FIRE
HAZARDS DUE TO DRY GRASS OR OTHER EASILY FLAMMABLE MATERIALS

Check and adjust steering head bearing*
Check steering head bearing for play periodically. To check this support the
motorcycle so that the front wheel is off the ground. Now try to move the
fork forward and backward - no play should be discernable For readjust-
ment, release the 5 clamp screws 1of the top triple clamp and turn the
top screw 2with the wrench 3from the tool set until no play is left at all.
Don’t tighten the steering stem bolt all the way, otherwise the bea rings will
be damaged. With a plastic hammer, lightly tap on the top triple clamp to
release tension. Re-tight the five clamp screws to 15 Nm (11 ft.lb).

WARNING

I F THE STEERING HEAD BEARING IS NOT ADJUSTED TO BE FREE OF PLAY , THE MOTORCYCLE
WILL SHOW AN UNSTEADY DRIVING PERFORMANCE AND CAN GET OUT OF CONTROL
.
!
CAUTION
!
IF YOU DRIVE WITH PLAY IN THE STEERING HEAD BEARING FOR LONGER PERIODS, FIRSTLY
THE BEARINGS AND THEN THE BEARING SEATS IN THE FRAME WILL BE DESTROYED.
The steering head bearings should be regreased after 2 years at the latest.
Changing the spring preload of the shock absorber
KTM sets the shock absorber for driver only, weighing approximately 75 kg
(165 lb). If you want to take a passenger with you, of if you weigh consi-
derably more or less than 75 kg (165 lb), you should change the spring
preload accordingly. This is easily done.
NOTE:
– Before changing the spring preload note down the basic setting, e.g.
how many coils are visible above the adjusting ring.
– One rotation of the adjusting ring 5changes the spring preload by
approximately 1.5 mm.
Use the hook wrenches included in the vehicle tool kit to loosen the coun-
ter ring 4. Change spring preload as desired by means of the adjusting
ring 5, and retighten counter ring.
Checking chain tension
– To check the chain tension, turn off the motorcycle.
– Press chain upward at the end of the chain sliding component. The
distance between chain and swing arm should be approx. 10 mm. In the
course of this procedure, the upper chain portion Amust be tensioned
(see drawing).
– If necessary, readjust chain tension.

Readjust chain tension
– Loosen collar nut 1, loosen counter nuts 2, and turn right and left
adjusting screws 3equally far. Tighten counter nuts.
– Before tightening the collar nut, verify that the chain tensioners 4are
sitting close to the adjusting screws and that the rear wheel has been
aligned with the front wheel.
– Tighten collar nut 1with 80 Nm (60 ft.lb).
Chain maintenance
O-ring chains require only modest maintenance. The best way is to use lots
of water, but never use brushes or solvents. After letting the chain dry, you
can use a special O-ring chain spray (Shell Advance Bio Chain).

WARNING

NO LUBRICATION IS ALLOWED TO REACH THE REAR TIRE OR THE BRAKE DISKS, EITHER-
WISE THE ROAD ADHERENCE AND THE REAR WHEEL BRAKING EFFECTS WOULD BE STRON-
GLY REDUCED AND THE MOTORCYCLE COULD EASILY GET OUT OF CONTROL.
!
CAUTION
!
WHEN MOUNTING THE CHAIN JOINT, THE CLOSED SIDE OF THE SAFETY DEVICE MUST
POINT IN RUNNING DIRECTION.
Also check sprockets and chain guides for wear, and replace if necessary.
Chain wear
In order to check the chain wear, regard the following instructions:
Shift the gear into idling and pull the upper chain strand with approx. 10-
15 kilogramm (33 lb) upwards (see figure). Now one can measure a space
of 18 chain reels at the lower chain strand. The chain should be replaced at
the latest when a space of 272 mm (10,70 in) is measured. Chains do not
always wear off evenly, therefore repeat the measurement at different pla-
ces on the chain.
NOTE:
If you mount a new chain, the sprockets should also be replaced. New
chains wear faster if used on old used sprockets.
General informations about KTM disc brakes
BRAKE CALIPERS:
The brake calipers of this series “float“. This means that the brake calipers
are not solidly attached to the caliper support. Thus, the brake pads are
always in optimum contact with the brake disc.
BRAKE FLUID RESERVOIRS:
The brake fluid reservoirs on the front and rear wheel brakes have been
designed in such a way that even if the brake pads are worn it is not neces-
sary to top up the brake fluid. If the brake fluid level drops below the mini-
mum either the brake system has a leak or the brake pads are completely
worn down.
In this case, consult an authorized KTM dealer immediately.
BRAKE FLUID:
KTM fills the brake systems with „Shell Advance Brake DOT 5.1“ brake
fluid, one of the best brake fluids that is currently available. We recom-
mend that you continue to use it. DOT 5.1 brake fluid is based on glycol
ether and of an amber color. If you do not have any DOT 5.1 for refilling,
you may use DOT 4 brake fluid. However, you should replace it as soon as
possible by DOT 5.1.

Hand brake lever, setting of pressure point
The pressure point is the point of resistance felt on the hand brake lever
when the brake pads contact the brake disc. The hand brake lever move-
ment from start to pressure point can be adjusted by adjustment screw 1.
This way the play can be adjusted to fit any hand size.
If you turn the adjusting screw clockwise - pressure point moves away
from throttle grip
If you turn it counterclockwise - pressure point moves toward throttle grip
Checking of brake fluid level - front brake
The brake fluid reservoir is linked with the hand brake cylinder at the hand-
lebar and the reservoir is provided with an inspection glass. With the reser-
voir in a horizontal position, the brake fluid level should not go below
middle of the glass.

WARNING

IF THE BRAKE FLUID LEVEL DROPS BELOW THE MINIMUM EITHER THE BRAKE SYSTEM HAS
A LEAK OR THE BRAKE PADS ARE COMPLETELY WORN DOWN. IN THIS CASE, CONSULT
AN AUTHORIZED KTM DEALER IMMEDIATELY.
Refilling the front brake reservoir*
Loosen screws 2and remove lid 3and membrane 4.
Place hand brake cylinder in a horizontal position and fill the brake fluid
reservoir to 5 mm (0.2 in) below the rim with brake fluid DOT 5.1 (Shell
Advance Brake DOT 5.1). Replace membrane and lid, tighten screws. Rinse
off spilled or overflowing brake fluid with water.

Changing the basic position of the foot brake pedal*
The basic position of the foot brake pedal can be altered by turning the
stop screw 1. The free play at the foot brake pedal must then be adjusted
by means of the push rod 2.
Measured on the outside, the foot brake pedal must have 3-5 mm
(0.12–0.20 in) of free play, before the push rod can move the piston in the
brake cylinder (to be recognised from the resistance on the foot brake
pedal). !
CAUTION
!
IF THIS FREE PLAY IS NOT PRESENT, THEN PRESSURE CAN BUILD UP IN THE BRAKE SYSTEM
WHEN DRIVING, CAUSING CONSTANT FRICTION OF THE BRAKE PADS.THE BRAKING
SYSTEM OVERHEATS AND CAN FAIL COMPLETELY IN EXTREME CASES.
Checking rear brake fluid level
The reservoir for the rear disc brake is located on the left-hand side of the
vehicle next to the carburetor connecting boot. The brake fluid level may not
drop below the „MlN” marking when the vehicle is in an upright position.

WARNING

IF THE BRAKE FLUID LEVEL DROPS BELOW THE MINIMUM EITHER THE BRAKE SYSTEM HAS
A LEAK OR THE BRAKE PADS ARE COMPLETELY WORN DOWN. IN THIS CASE, CONSULT
AN AUTHORIZED KTM DEALER IMMEDIATELY.
Refilling the rear brake reservoir*
When the brake fluid level has dropped to the MIN mark, you need to refill
the brake fluid reservoir. This is done by first unscrewing the cap 3and
rubber boot 4. Add brake fluid DOT 5.1 (Shell Advance Brake DOT 5.1)
until it reaches the MAX mark, then screw rubber boot and cap back on.
Rinse off spilled or overflowing brake fluid with water.
