In case of Production consistency check test, the volume concentration of emitted
CO is ≤4.0%; and the volume concentration of emitted HC is ≤1000×10-6.
The environmental protection device is mainly a two-in-one air
compensating valve (air pump) combining a one-way leaf valve
and a secondary air control valve. By making use of the engines
vacuum pulsation, the air pump controls the amount of air
needed to enter the exhaust port through the one-way leaf valve
and the secondary air control valve. This fresh air enters the
exhaust passage of the engine under the action of the air pump.
Unburned fuel vapor discharged from the engine in its exhaust
is then consumed. Thusly this device reduces the exhaust
pollution of the vehicle, and ensures that the vehicles exhaust
meets National Stage III emission standards.

USER’S MANUAL
Common Faults and Troubleshooting
Service and Maintenance for the Carburetor
For maximum performance and reliability, it is important the
carburetor is adjusted properly. Failure to do so will affect starting;
idle, as well as the overall vehicles performance.
The carburetor should be serviced and maintained as follows:
1. Regularly check all connections and fittings on the carburetor.
A poor fit between the intake manifold and carburetor can
result in hard starting, poor performance and lower gas
mileage.
2. Check the rubber fuel lines for signs of weathering. If any
cracks or deterioration are found, replace them.
3. Start and drive your vehicle often. Gasoline left sitting for a long
period of time will start to break down, becoming “stale”. The
longer a vehicle sits the more likely the carburetor is to develop
issues due to stale fuel contamination.
4. If the vehicle is to be stored for any length of time longer than 2
weeks, the fuel in the carburetor bowl and fuel tank must be
drained from the vehicle into an approved container for use
elsewhere. Failure to do so will result in a contaminated,
"clogged” carburetor. This will cause hard starting and poor
performance. The carburetor will then have to removed and
thoroughly cleaned or, as in many cases, replaced.
Draining the fuel is quite simple. You will find a length of fuel
line running from the bottom of the carburetor to a bracket on the
frame. In that bracket, there will be a brass screw plug that when
removed will allow fuel to drain out of the carburetor bowl. Fuel can
be easily syphoned from the fuel tank.

USER’S MANUAL
Check and Replacement of Lubricating Oil
Caution
Checking and Replacing Engine Oil
To ensure an accurate reading when checking the engine oil, place the vehicle on the
center main stand. Only check the oil level after the engine has been shut off for at
least 5 minutes. Be aware the engine, exhaust and engine oil will be extremely hot if
the engine has been running. It is recommended you allow the engine to cool for at
least 30 minutes after a long drive before checking.
-Remove oil cap. Note if there is oil on the dipstick. A lack of oil on the dipstick
indicates a low oil level.
-Wipe the dipstick clean and insert into engine. Quickly withdraw the dipstick and
note the oil level. If there is no oil on the dipstick, oil will need to be added.
-Note the color of the oil. Very black oil indicates the oil must be drained and replaced.
-To drain the engine oil, loosen the 17mm oil drain plug on the bottom right hand side
of the engine, directly underneath the black engine shroud.
-Allow oil to drain completely. Not allowing all the oil to drain will result in residual oil
left in the crankcase which will alter the amount needed to fill the engine.
-Inspect oil filter and clean if necessary.
-Reattach oil drain plug with spring and filter installed.
-Fill with ~750mL (25 oz.) of 15W-40 (or 5W-40 if synthetic) engine oil through the oil
dipstick opening.
-Insert dipstick and withdraw to verify correct oil level.
-Tighten dipstick and inspect for leaks.
With the vehicle on the center kick stand,
unscrew the oil dipstick and wipe clean
with a rag. Insert the dipstick, pull out,
and check the level and color of the oil.
The oil level should always be between
the upper and lower oil level markings on
the dipstick.
Following the service intervals in this
manual, drain and replace the oil as
necessary. The 17mm bolt on the bottom
of the engine needs to be removed to
drain the oil. Be sure to clean the mesh
filter screen before reinstallation.
After the engine has drained completely,
reinstall the mesh screen into the spring.
Place the spring into the drain plug and
reattach to the engine. Refill the engine
with oil.

USER’S MANUAL
Common Faults and Troubleshooting
Service and Maintenance of the Spark Plug
Remove the spark plug from the engine. If the color of the insulator
skirt of the spark plug is brown it indicates that the carburetor is
adjusted properly. Any signs of buildup on the plug should be noted
as this could be a sign of an incorrect carburetor adjustment.
Cleaning the Spark Plug
Inspect the spark plug for carbon buildup. If there are noticeable
deposits or wear on the spark plug, replace.
It is normal for the
spark plug to be
light brown. This
indicates a proper
air fuel mixture.
Correct spark plug gap helps fuel
economy and performance.
Incorrectly gapped spark plugs can
lead to hard starting and poor
performance. Always replace the
spark plug with the original NGK
replacement.
When removing and
tightening the spark plug, be
sure to use the correctly
sized socket. Improper
removal can result in spark
plug damage that can result
in costly repairs.
Check the electrode
gap of the spark plug
with a gauge and
adjust the gap to 0.025
inches.

USER’S MANUAL
Service and Maintenance for the Air Filter
When dust builds up in the filter element of the air filter assembly, it
results in an increased resistance to air flow through the air intake
system. This leads to an overly rich fuel/air mixture that can reduce
power and increase fuel consumption. It is important the air filter be
cleaned or replaced on a regular basis. Riding in dusty conditions will
require more frequent filter maintenance.
Caution
* Do not use the following cleaning agents to clean paper filter
elements: Gasoline, low ignition-point solvent, acid, alkaline or
organic volatile oil.
Take off the screws
for the air filter
cover, and remove
the air filter cover.
Check whether there
is dust and dirt on
the sponge of the
filter element.
Remove the air filter
and wipe off the dust
inside the air filter
with clean and dry
cloth.
Paper based filters are a disposable item and just need to be
replaced. You can find them at your Wolf Brand dealership

Service and Maintenance for the Environmental Protection Device
Vehicle operators must conduct regular service and maintenance of the environmental protection system to ensure the best performance of the
assembly. With proper and regular service and maintenance, we can promptly eliminate faults, prolong the service life of the environmental
protection system, reduce the maintenance costs, and realize the goal of being environmental-friendly by reducing your vehicles fuel
consumption.
Caution
The carburetor of the environmental protection device must be
serviced and maintained by a professional motorcycle repair shop or
the dealer’s after-sales service personnel (make sure not to adjust the
carburetor without authorization)
1 Regularly check whether there is any aging, air leakage or
damage on the intake negative pressure hose and the intake
plastic hose. If any, replace the intake negative pressure hose and
the intake plastic hose.
2 Regularly check the working conditions of the air pump of the
environmental protection device. If the air pump is blocked or
cannot work properly, replace the air pump of the environmental
protection device.
3 Regularly check the air filter. If any dust or dirt exists on the air
filter, the air flow will be reduced, thus changing the
concentration of the gas mixture, and increasing fuel
consumption. Therefore, it must be changed.
4. Regularly check the clamp for the intake vacuum hose, the
clamp for the clean air feed, and the mounting bolt for the metal
air pump intake pipe. If they are loose, tighten them.

Service and Maintenance for the battery
In this model, the battery is mounted under the floor mat. For the first
500 to 1000 miles of the vehicle, the battery should be serviced and
maintained as follows:
1. Keep the battery poles clean of corrosion.
2. Make sure the positive and negative electrode connections are
not loose.
3. If the vehicle is not going to be used for more than 2 weeks, the
battery should be disconnected and maintained on a trickle
charger.
Make sure the positive and negative
electrode connections are clean and tight.
When checking the voltage of the battery, a reading of less
than 12 volts is not normal. You should also “load test” the
battery to determine if the battery needs to be replaced. or just
charged. This can be done at most auto parts stores
If your battery is showing a voltage
level less than 12v, and passes a
“load test” place it on a battery
charger.

Service and Maintenance for the Horn
Over time the horn may need to be adjusted. By removing the front
panel, you can access the horn and adjustment screw.
If the entire electrical system of the vehicle is not functioning,
check the fuse first. A blown fuse will cause all electrical
components including the electric start to stop functioning.
If the horn sound becomes weak or isn’t working at all, remove the
front cover, and use a multi-meter to measure the voltage of the horn
circuit. You must do this with the ignition turned on. and it should
measure 12 Volts DC. If that is the reading you find, you should then
use the adjustment screw in the middle of the horn to get the correct
horn sound. If you do not get a read from the multi-meter on the horn
circuit, you should have the vehicle checked out by your local WOLF
Brand Scooter Dealer.
