andmaintenance
!Warning
Please read the Briggs&Stratton engine user’s
manual carefully before using Snowdog. All the
information on engine maintenance contained
in this manual serves as guidelines. If the
maintenance instructions in this Snowdog
owner’s manual are different from those in the
Briggs&Stratton engine user’s manual, follow the
instruction specified in the latter.
8.1 Engine oil
Recommended oil
Use engine oil that meets or exceeds SJ or SL standards of
API. Do not use special additives. Always check the API
service mark on the oil container to be sure it contains the
letters SJ, SL or equivalent.
8.1.1 Checking oil level
Oil level should be checked with the engine shut off and on
a horizontal surface.
1. Take the dipstick off and wipe it clean.
2. Put the dipstick into the oil fill neck to measure the
oil level, but do not tighten it. Take the dipstick out
and check the oil level.
3. If the oil level is near or lower the minimum mark on
the dipstick, add the recommended oil to the upper
mark level (lower edge of the oil fill). Do not pour oil
above the level.
4. Put the dipstick back.

12
!Warning
Operation with low oil level may damage the
engine.
Increased oil level indicates water or fuel ingress.
Do not start the engine if the dipstick is taken out.
8.1.2 Changing the oil
Change the oil for the first time after 5 hours of engine
operation.
Then change the oil every 50 hours of engine operation.
Change the oil only in a warmed-up engine.
1. Take the dipstick off and clean the oil fill area of any
debris.
2. Pump the oil out through the oil fill. Please make
sure to dispose of the used oil in an environmentally
safe way. We recommend that you take the used oil
in a closed container to your nearest waste disposal
site.
!Warning
Dispose of the oil in accordance with current
legislation.
3. The engine should be located on a horizontal
surface. Add the recommended oil to the upper
mark level (lower edge of the oil hole).
4. Put the dipstick cap back and tighten it.
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 flammable 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 flames around.
Refuel only outdoors or in a well-ventilated area and only
if the engine is stopped. If the engine has been recently
running, let it cool down first.
Spilled fuel is not only highly flammable 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 filler neck, as shown in
Figure.
!Warning
Do not fill the tank with fuel above the maximum
level. The fuel expands when heated. If the tank is
overfilled, then the fuel heated by engine or sun
can leak from the tank.
Do not spill fuel, especially on the engine and the
muffler as it may cause fire 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 leans 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. Correctly tensioned chain will
have a loose lift of 0.2 in (5 mm) between the sprockets.
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.

13
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 lubricate
for motorcycle chains. Lubrication should be sprayed into
the gap between the links and rollers of the chain. Wipe the
excess lubricant with a dry cloth.
!Warning
It is recommended to use aerosol lubricates for
motorcycle chains.
8.3.3 Adjusting the chain tension.
To adjust the chain tension:

8.10 Battery maintenance
The Snowdog can be equipped with a Delta CT 1211
(12V/11A·h) battery or its alternatives: MG12ZS-C, ЕВZ12-4-
1, YТ12В-BS, YТZ14S.
Service life of a battery depends on its operating conditions.
When the engine is started with an electric starter, the
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V. If the battery voltage is less than 12.3V, 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 switched 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.

8.11 Parking brake
8.11.1 Brake cable adjustment
Check the free movement of parking brake lever A. It should
have a value of 0.2–0.4in (5–10mm).
To do this, loosen the locknut (1) and rotate the adjusting
screw (2) counterclockwise to pull cable so that the brake
lever has a free run within 0.2–0.4in (5–10mm).
To loosen the brake cable, loosen the locknut (1) and rotate
the adjusting screw (2) clockwise.
If the adjustment capability at the lever is at its maximum
and the brake is still not performing adequately, then
there’s also adjustment capability at the brake caliper. If this
is the case, the adjustment at the lever should be backed
off, as in loosened the opposite way of what you’re trying to
achieve, then adjust the brake at the caliper. The brake lever
adjustment should be left for finer adjustment of the brake.
8.11.2 Adjusting the brake caliper on the Snowdog with
the reverse gearbox
Fully loosen the tension of the brake cable on the lever.
Lever should move freely without binding or restriction. If it
does not, lubricate or replace the cable.
Loosen the screw (1) and pull the cable until the necessary
clearance between the brake pads and the brake disk is
setup.
Tighten the screw (1) and check the movement of the
parking brake lever.

rotate freely. At this point the brake adjustment should be
loosened.
8.12 Adjusting the throttle
To adjust the throttle lever, loosen the locknut (2) and rotate
the adjusting screw (1) counterclockwise. Pull the rope so
that the throttle has a free run within 0.2–0.3in (5–7mm).
1. To loosen the throttle cable, loosen the locknut (2)
and rotate the adjusting screw (1) clockwise. Loosen
the cable.
