4.2 WHEEL DRIVE CONTROL ADJUSTMENT
IMPORTANT: There should always be some slack in
the wheel drive control cable when the wheel drive
control is released.
The Wheel Drive Control requires periodic
adjustment to maintain proper belt tension on the
transmission poly-v belt. Verify proper tension by
checking the extension of the spring located at the
end of the wheel drive control cable.
1. Stop engine and allow sufficient time to cool.
2. Engage wheel drive control. The length of the
spring located at the end of the drive control cable
should increase between ½" and ¾". See Figure 4.4.
If the spring does not increase between ½" and ¾",
adjustment is required.
3. To adjust the amount the spring extends (belt
tension) slide the black spring cover up to expose
the spring. Unhook the cable eyelet from the spring.
4. Grip the hook on the spring and turn either
Clockwise or Counter-clockwise. Clockwise
increases spring extension and belt tension
Counter-clockwise decreases spring extension and
belt tension.
5. Attach the control cable eyelet to the spring and
recheck spring extension. If spring extension is
correct slide the spring cover down over the spring.
Start engine, and with blade control released (blade
stopped) verify the wheel drive functions properly. If
spring extension is not correct turn spring

how dirt can
[e
& how
maintenance
can protect it!
Snapper uses the best avail-
able engines and components
In their products in order to
provide long, satisfactory
service. However, proper
care is essential In
prolonging engine life. Dirt
Is your engine's enemy
number 11
The engine on your Snapper
product spends Its entire life
operating close to the ground at
high speed creating a virtual
storm of dust and dlrtl
22
PRIMARY MAINTENANCE
gulp about 12,000
gallons of air for
every g
used. Because of
its working environ-
ment, the air available
to your Snapper engine Is "
heavily saturated with air-
borne dirt particles.
g that dirt will
quickly ruin an engine,
manufacturers equip their
engines with extremely
efficient air cleaners to
filter out the harmful dirt.
As the dirt particles are stopped,
they build up and begin to clog
the outside of the filter. This
reduces the amount of air
available to the engine and causes
an over-rich fuel mixture which re-
sults In the following adverse
effects:
An Improperly serviced, dirt
clogged air cleaner will:
1. Increase fuel consumption
2. cause power loss
3. result in hard starting
4. create smoke from unburned
fuel
5. produce carbon build-up ;
Internally
6. foul spark plug electrodes
7. score cylinder walls
8. burn valves
9. wear out the engine pre-
maturely
10. COST YOU MONEY!
Damage caused by a poorly serviced air
cleaner Is not covered under the engine
warranties. So, save yourself unnecessary
expenses and undue aggravation by keeping
the air cleaner properly serviced at the Intervals
specified In the engine owner's manual.
It doesn't take long to service an air cleaner.
Follow the specific Instructions In the engine
owner's manual for the type filter used. Pre-
vent dirt from falling Into the carburetor Intake
when servicing your air cleaner. Make sure
components are Installed in correct sequence
after servicing to prevent unfiltered air from
entering the engine. Some servicing hints on
several common types are:
23
PRIMARY MAINTENANCE
Generally, wash foam-type filters
In a dlshwashlng detergent and
water solution. Rinse and wring
dry, then saturate with oil and
squeeze out excess. Failure to
re-oil this type filter will ruin the
engine.
Clean paper elements by tapping
lightly. Blowing with air will
rupture paper elements.
Use a flashlight to detect clogged
or torn paper elements - replace If
damaged In any way.
Air Is also needed to keep
your engine cool. Dirt, dust
& debris build up to restrict
and clog cooling air Intake
screens and fins. Clean
screens and fins at frequent
Intervals. The engine blower
housing and shrouds should
be removed at least once
each season or more often
under dry, dusty conditions
for a thorough cleaning of
fins.
Failure to keep external
surfaces clean not only
presents fire hazards, but
'causes overheating and
resulting engine damages
such as:
1. distorted valve guides
2. sticking valves
t ° o. 3. scuffed,
,.,. walls
4. overspeedlng
5. loss of power
6. complete failure of
engine.
Dirt can also be Introduced
into an engine In dirty fuel
from a contaminated
container. Always use clean
fresh fuel from a clean
container to guard against
dirt, sludge and water
contamination.
Be aware that fuel breaks
down in storage and forms
gummy compounds which
will block carburetor pass-
ages. Never use fuel more
than 3 months old. Drain
tank then run the engine out
of fuel before storing during
the off-season.
An engine must also have proper lubrication.
All engines use some oil. On 4-cycle engines,
CHECK OIL LEVEL BEFORE EACH START-UP.
Wipe area clean around the oll check plug or
dipstick opening to keep dirt from falling into
the engine when checking the oil. Always
check with the machine on a level surface.
On engines with dipstick, keep the level up to,
but not over, the FULL mark. When adding o11,
allow time for all of the oll to flow down the fill
tube to prevent a false full reading when the
level could actually be low and result In engine
damage.
24
PRIMARY MAINTENANCE
On 4-cyle engines with an oil level plug,
don't be fooled into thinking the engine has
sufficient lubricating oii if you can see "some"
oil in the opening - the level should always be
brought up to the point of Ig at the
top of the fill hole.
On 2-cycle engines, lubrication must be
provided by an exact mixture of gasoline
and 2-cycle air-cooled engine oil. A 2-cycle
engine that Is mistakenly run on straight
gasoline will be ruined in less than 5
minutasl If you keep straight gasoline In
addition to pre-mixed 2-cycle engine fuel,
be sure the containers are clearly marked
to avoid mix-up.
Snapper 2-cycle engines require a 32 to 1
mixture of gasoline and BIA certified TC-W
oil such as Snapper's 2-cycle engine oil
Many of the 2-cycle engine oils on the
market today make fantastic claims, but for
the best performance and long engine life,
always use Snapper 2-cycle oil Pre-mix
the fuel and always shake the container
before filling the tank.
Change oil at regular Intervals using a a high
quality oil such as Snapper's small engine
formulated 4-cycle engine oil Refer to the
engine owner's manual for oil details.
