corners, shrubs, trees, or other objects that may
obscure vision.

PROTECTION AGAINST TIPOVERS

Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe
injury or death. All slopes require extra CAUTION. If
you cannot back up the slope or if you feel uneasy on
the slope, DO NOT mow it. Use extra care with grass
catchers or other attachments; these and turf
conditions affect the handling and the stability of the
machine.

1. DO NOT operate machine on slopes exceeding 15
degrees (27% grade).

2. Exercise EXTREME CAUTION on slop es above 10
degrees (18% grade). Turn blades OFF when
traveling uphill. Use a slow speed and avoid
sudden or sharp turns.

3. DO NOT operate machine back and forth across
face of slopes. Operate up and down. Practice on
slopes with blades off.

4. AVOID uphill starts. If machine stops going uphill
or tires lose traction, turn blades OFF and back
slowly down the slope.

The following mower deck and component
adjustments and repairs can be made by the owner.
However, if there is difficulty in making these
adjustments and repairs, it is recommended that
these repairs be made by an authorized SNAPPER
dealer.

5.2.1. MOWER DECK ADJUSTMENT (LEVELNESS)

SIDE to SIDE and FRONT to REAR

Before making deck leveling adjustments,
check tires and add or release air as needed to
bring pressure to 12 psi in dr ive tires. Pr essur e
in front caster wheels should be 25 psi.
If tires are properly inflated and mowing is still
uneven, adjust deck levelness as follows:

SIDE to SIDE LEVEL

1. Place machine on a smooth level surface.

2. Check blade tips by rotating blades until tips

are pointing to the sides of the deck. Check the
measurement of outside blade tips to the
ground on both blades. The measurement of
each of the outside blade tips should be within
1/8” of each other. If measurement of the blade
tips is not within 1/8”, adjustment should be
made to the higher side of the deck to lower it
to within the correct measurement.

3. Move deck lift lever and set the mower deck
to the highest cutting position.

4. Plac e a wooden block under the front and
rear edge of the mower deck.

5.7.4. BATTERY TESTING

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 c ondition 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
before testing. The Battery Condition Chart
shows the charge level as measured by
syringe float hydrometer, digital voltmeter
and five ball hydrometer.

5.7.5. NEW BA TTERY PREPARA TION

1. Remove battery from carton.

2. Place battery in a well ventilated area on a

level non-concrete surface.

3. Remove battery cell caps. Fill cells as
required with electrolyte (purchased
separately) to proper level. Fill to 3/16”
above cell plates. Filling battery with
electrolyte will bring the battery to 80%
charged state.

4. With cell caps removed, connect battery
charger to battery terminals; RED to positive
(+) and BLACK to negative (-) terminal.

IMPORTANT: 3/16” above cell plates is the recommended
level. DO NOT place anything in battery other than specified
electrolyte.

WARNING

DO NOT OVERFILL!

DO NOT attempt to service or charge the battery
while it is installed in the machine. DO NOT use
“BOOST” chargers on the battery.

Shield the positive terminal with terminal cover
located on battery harness. T his p rev ent s metal f rom
touching the positive terminal, which could cause

sparks. Cables must be connected to battery

terminals in the proper position. RED (Positive) cable
must go to the ( + ) terminal. BLACK (Negative) cable
must go to the ( - ) terminal.

WARNING

5. Slow charge the battery at 1 amp for 2

hours to bring the battery to full charge.

6. After char ging, check level of electrolyte
and add as needed to bring level to 3/16”
above cell plates.

7. Reinstall cell caps.

8. Install battery into power unit.

9. Connect positive (+) cable (red) first,

from wiring har ness to the pos itive term inal
