Use engine oil that meets or exceeds SJ and SL
standards of API� Do not use special oil additives� Always
check the API service mark on the oil container to make sure it
contains SJ, SL or equivalent symbols.
SAE 10W-30 or SAE 5W-30 oil is recommended for
common use� Engine oil capacity is 1�1 liters�
8.2 Fueling
!WARNING!
Fill the gasoline engine according to the
Briggs&Stratton engine manual.
!Fuel is highly fl ammable and explosive, you
should avoid getting burned and injured
while working with it.
Stop the engine before refueling. Make sure there are no
heating appliances, sparks or  ames around.
Refuel only outdoors.
Refuel only in a well-ventilated area and only if the
engine is stopped. If the engine has been recently running, let
it cool down  rst.
Spilled fuel is not only highly  ammable but toxic and
may be harmful to people and the environment. If fuel spills,
wipe it up as soon as possible�
Make sure that there is enough fuel in the tank. Fill the
fuel tank up to the bottom part of the  ller neck, as shown in
Figure�
!WARNING!
Do not  ll the tank with fuel above the
maximum level. The fuel expands when
heated. If the tank is over lled then the fuel
heated by engine or sun can leak from the
tank.
!Do not spill fuel, especially on the engine and
the muffl er as it may cause  re and heavy
injuries. Wipe the spilled fuel dry.
After refueling make sure that the cap of the
fuel tank is sealed tightly.
!If the SNOWDOG will lean heavily or turn
over it is possible for the fuel to leak through
the fuel tank cap.
8.3 Chain
8.3.1 Checking the chain tension
Visually inspect the proper tension of the chain after
each use� There should be no damage to the rollers or chain
links� There should be no jamming or rusty links�
It is necessary to remove the protection cover (if
available) to check the chain tension or change the sprocket
or chain� Correctly tensioned chain will have a loose lift of
0,2 in (5 mm) between the sprocket. Loose lift less than 0,2
in (5 mm) will result in rapid chain wear, and will lead to fast
sprocket wear. An excessively loose chain can fall off during
operation� Loose chain needs to be tightened�
While operating, the chain stretches, and the distance
between chain links changes� If the adjustment range is not
enough, the chain should be replaced. Do not shorten the
chain by removing links�
8.3.2 Chain lubrication
During visual inspection, it should be clear that the chain
is lubricated. However, it should not be lubricated excessively
so as to avoid sand and dirt sticking. Before lubrication, clean
the chain of dirt and the old lubricant with an aerosol cleaner
or a cloth moistened in kerosene or solvent. After cleaning,
wipe the chain dry�
After cleaning the chain, lubricate it with aerosol

The Snowdog can be equipped with a Delta CT 1211
(12V/11Ah) battery or its alternatives: ЕВZ12-4-1, YТ12В-BS,
YТZ14S.
Service life of a battery depends on its operation mode�
When the engine is started with an electric starter, the
5
6
battery gives up part of the charge and later makes up for this
loss during the driving� Prolonged driving at low speeds with a
headlight switched on, as well as frequent starts of the engine
result in the battery not having enough time to charge� The
voltage of a charged battery should be 12�6–12�9 volts� If the
battery voltage is less than 12.3 volts, the charge is around
70%� Charge the battery�
!WARNING!
Do not store the battery discharged. Leaving
the battery discharged or storing it at low
temperatures for a long time leads to its
damage.
Connect and disconnect the battery only when the
ignition is turned off . Connect the red wire to the plus (+)
terminal; connect the blue or black wire to a minus (-) battery
terminal�
!WARNING!
Incorrect battery connection will damage the
Snowdog.
To charge the battery, use a charger for AGM batteries.
!WARNING!
The use of a charger that is not intended for
AGM batteries will lead to the failure of the
battery.
