PROTECTION FOR CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine and the mowing activity. Never assume that
children will remain where you last saw them.
1. KEEP children out of the mowing area and under the
watchful care of a responsible adult.
2. DO NOT allow children in yard when machine is
operated (even with the blade OFF).
3. DO NOT allow children or others to ride on machine,
attachments, or towed equipment (even with the
blades OFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operate
machine.
5. ALLOW only responsible adults & teenagers with
mature judgment under close adult supervision to
operate machine.
6. DO NOT operate blades in reverse. STOP BLADES.
LOOK and SEE behind and down for children, pets and
hazards before and while backing.
7. USE EXTRA CARE when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.
PROTECTION AGAINST TIPOVERS
Slopes are a major factor related to loss-of-control and tipover 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 affect the handling and the stability of the machine.
1. DO NOT operate machine on slopes exceeding 10
degrees (18% grade).
2. Exercise EXTREME CAUTION on ALL slopes. 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 starting, stopping and turning on slopes. If
machine stops going uphill or tires lose traction, turn
blades OFF and back slowly straight down the slope.
5. STAY ALERT for holes and other hidden hazards. Tall
grass can hide obstacles. Keep away from ditches,
washouts, culverts, fences and protruding objects.
PROTECTION AGAINST TIPOVERS
(Continued From Previous Column)
6. KEEP A SAFE DISTANCE (at least 3 feet) away from
edge of ditches and other drop offs. The machine
could turn over if an edge caves in.
7. Always begin forward motion slowly and with caution.
8. Use weights or a w eighted load carrier in accordance
with instructions supplied with a grass catcher. DO
NOT operate machine on slopes exceeding 10 degrees
(18% grade) when equipped with grass catcher.
9. DO NOT put your foot on the ground to try to stabilize
the machine.
10. DO NOT operate machine on wet grass. Reduced
traction could cause sliding.
11. Chose a low enough ground speed setting so that you
will not have to stop or shift on a slope. Tires may lose
traction on slopes even though the brakes are
functioning properly.
12. DO NOT operate machine under any condition where
traction, steering or stability is doubtful.
13. Always keep the machine in gear when going down
slopes. DO NOT shift to neutral (or actuate the hydro
roll release) and coast downhill.
PREPARATION
1. Read, understand, and follow instructions and
warnings in this manual and on the machine, engine
and attachments. Know the controls and the proper
use of the machine before starting.
2. Only mature, responsible persons shall operate the
machine and only after proper instruction.
3. Data indicates that operators age 60 and above, are
involved in a large percentage of mower-related
injuries. These operators should evaluate their ability
to operate the mower safely enough to protect
themselves and others from serious injury.
4. Handle fuel with extra care. Fuels are flammable and
vapors are explosive. Use only an approved fuel
container. DO NOT remove fuel cap or add fuel with
engine running. Add fuel outdoors only with engine
stopped and cool. Clean spilled fuel from machine. DO
NOT smoke.
5. Practice operation of machine with BLADES OFF to
learn controls and develop skills.
6. Check the area to be mowed and remove all objects
such as toys, wire, rocks, limbs and other objects that
could cause injury if thrown by blade or interfere with
mowing.

4.5.5. 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 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.
4.5.6. NEW BATTERY PREPARATION
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. 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.
WARNING
DO NOT OVERFILL! DO NOT attempt to charge
battery while installed on the SCRAMBLER. DO NOT
use “BOOST” chargers on the battery.
