catcher or unclogging mower to prevent loss of  
fingers or hand.  
6. Blades must be OFF except when cutting grass.  
Set blades in highest position when mowing  
over rough ground.  
12. Use extra care when loading or unloading the  
machine into a trailer or truck.  
13. Check grass catcher components frequently for  
signs of wear or deterioration and replace as  
needed to prevent injury from thrown objects  
going through weak or worn spots.  
7. Keep hands and feet away from rotating blades  
underneath deck. DO NOT place foot on ground  
while BLADES are ON or machine is in motion.  
8. DO NOT operate machine without entire grass  
catcher or guards in place and working. DO  
NOT point discharge at people, passing cars,  
windows or doors.

WARNING  
4.6 BATTERY  
The electrolyte (acid) produces a highly explosive gas.  
Keep all sparks, flame and fire away from area when  
charging battery or when handling electrolyte or  
battery. Electrolyte (acid) is a highly corrosive liquid.  
Wear eye protection. Wash affected areas immediately  
after having eye or skin contact with electrolyte (acid).  
Battery acid is corrosive. Rinse empty acid containers  
with water and mutilate before discarding. If acid is  
spilled on battery, bench, or clothing, etc., Flush with  
clear water and neutralize with baking soda. DO NOT  
attempt to charge battery while installed on the  
SCRAMBLER. DO NOT use “BOOST” chargers on the  
battery. If battery is removed, DO NOT operate engine  
without insulating Positive + battery cable terminal with  
electrical tape, or sparking from the battery cables can  
result.  
4.6.1. BATTERY REMOVAL  
1. Tilt seat up to gain access to battery.  
2. Observe and note cable positions on battery.  
See Figure 4.18.  
3. Disconnect cables from battery terminals,  
disconnecting BLACK (Negative) cable first.  
Disconnect RED (Positive) battery cable. Slide  
battery from battery cradle.  
4. Retain mounting bolts and nuts for future use.  
4.6.2. BATTERY INSTALLATION  
1. Slide battery into battery cradle.  
2. Connect cables to battery terminals. Connect  
RED (Positive) cable first. Connect BLACK  
(Negative) cable. See Figure 4.18.  
3. Place the positive (+) terminal insulator over  
positive terminal and cable. See Figure 4.18.  
4.6.3. BATTERY SERVICE  
1. Remove battery. Refer to Section “BATTERY  
REMOVAL”.  
2. Place battery in a well-ventilated area on a level  
surface.

and black to negative (-) terminal.  
25  
Section 4 - ADJUSTMENTS & REPAIR  
IMPORTANT: DO NOT place anything in new battery  
other than specified electrolyte.  
4.6.5. 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.  
5. Slow charge the battery at 1 amp for 2 hours to  
bring the battery to full charge.  
6. After charging, check level of electrolyte and  
add as needed to bring to proper level.  
7. Reinstall cell caps.  
8. Install battery into power unit. Connect over flow  
tube.  
9. Connect positive (+) cable (red) first, from wiring  
harness to the positive terminal (+) on battery  
using bolt and nut provided in hardware bag.  
Connect negative (-) cable (black) last, to negative  
terminal (-) on battery using bolt and nut. Apply a  
small amount of grease over terminals to prevent  
corrosion.  
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.  
WARNING  
Shield the positive terminal with terminal cover  
located on battery harness. This prevents metal from  
touching the positive terminal, which could cause  
sparks.  
4.6.6. 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.
