There are two types of battery tests: Unloaded and
Loaded. The unloaded test is the procedure that
will be discussed. It's the simplest and most
commonly used. An unloaded test is made on a
battery without discharging current. To perform
unloaded testing, check charge condition using
either a hydrometer or voltmeter.
1. Using a voltmeter, voltage readings appear
instantly to show the state of charge. Remember to
hook the positive lead to the battery's positive
terminal, and the negative lead to the negative
terminal.
2. A hydrometer measures the specific gravity of
each cell. The specific gravity tells the degree of
charge; generally, a specific gravity of about 1.265
to 1.280 indicates full charge. A reading of 1.230 to
1.260 indicates the battery should be charged. The
Battery Condition chart below shows the charge
level as measured by syringe float hydrometer,
digital voltmeter and five ball hydrometer.

Section 4 - ADJUSTMENTS & REPAIR
WARNING
DO NOT attempt any adjustments, maintenance,
service or repairs with the engine running. Stop
engine. Stop blade. Engage parking brake. Remove
key. Remove spark plug wire from spark plug and
secure away from plug. Engine and components
are HOT. Avoid serious burns, allow all parts to
cool before working on machine. Fuel Filler Cap
and Vent must be closed securely to prevent fuel
spillage.
4.6 JOYSTICK ADJUSTMENTS
4.6.1. Neutral Position Adjustments
The joystick controls the movement and stopping of the
unit. Move the joystick to the center or neutral position
to stop mower. IMPORTANT: Always return the joystick
with hand assistance to the neutral position. If mower
does not come to a complete stop or has any
movement when joystick is moved to the neutral
position, adjustment must be made. It is recommended
that these adjustments be made by an authorized
SNAPPER dealer. But, adjust joystick cables as follows
after removing fenders:
1. If mower tracks to the right, loosen bottom nut
first on the right cable. Turn top nut clockwise in a
1/8 increment then retighten lower nut to secure
cable. Check tracking of mower. Repeat this
adjustment if necessary. See Figure 4.1.
2. If mower tracks to the left, loosen bottom nut
first on the left cable. Turn top nut clockwise in a
1/8 increment then retighten lower nut to secure
cable. Check tracking of mower. Repeat this
adjustment if necessary. See Figure 4.1.
4.6.2. Forward Speed Adjustments
The joystick is equipped with a forward speed governor
plate (see Figure 4.1a). Moving the plate in or out
adjusts the maximum forward speed the unit can
achieve. To adjust the plate:
1. Loosen the two front torx screws on the joystick
control.
2. To increase maximum forward speed, slide the
plate further out from the joystick. To decrease
maximum forward speed, slide the plate further in
toward the joystick
3. Be sure to retighten torx screws after
satisfactory speed is achieved.

PRIMARY MAINTENANCE
Generally, wash foam-type filters
In a dlshwashlng detergent and
water solution. Rinse and wring
dry, then saturate with oll 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 fleshllght 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 overheaUng and
resulting engine damages
such as:
1. distorted valve guides
2. sUcking valves
.3. scuffed,
4. walls
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 s clean
container to guard against
dirt, sludge and water
contamination.
Be aware that fuel breaks
down In storage and forms
will block carburetor pase-
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 cbecklng the o11.Always
check with the machine on a level surface.
On englnee 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 feeding when the
level could actually be low and result In engine
damage.

PRIMARY MAINTENANCE
On 4-cyle engines with an oll level plug,
don't be footed Into thinktng the engine has
sufficient lubricating all If you can see "some"
oll In the opening - the level should always be
brought up to the point of €
top of the fill hole.

On 2-cyele engines, lubrication must be
provided by an exact mixture of gasoline
