of any reason.  
4. DO NOT operate machine unless properly  
seated with feet on feet rests or pedal(s).  
5. STOP BLADES and ENGINE and make sure  
blades have stopped before removing grass  
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.  
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

clothes dryer or other gas appliance. Allow  
engine to cool before storing machine in an  
enclosure. Store fuel container out of the reach  
of children in a well ventilated, unoccupied  
building.  
2. Keep engine free of grass, leaves or excess  
grease to reduce fire hazard and engine  
overheating.  
3. When draining fuel tank, drain fuel into an  
approved container outdoors and away from  
open flame.  
4. Check brakes frequently; adjust, repair or  
replace as needed.  
5. Keep all bolts, nuts and screws properly tight.  
Check that all cotter pins are in proper position.  
6. Always provide adequate ventilation when  
running engine. Exhaust gases contain carbon  
monoxide, an odorless and deadly poison.  
7. Disconnect negative (black) cable from battery  
before performing maintenance or service.  
Cranking engine could cause injury.  
8. DO NOT work under machine without safety  
blocks.  
9. Service engine and make adjustments only  
when engine is stopped. Remove spark plug  
wire(s) from spark plug(s) and secure wire(s)  
away from spark plug(s).  
10. DO NOT change engine governor speed  
settings or overspeed engine.  
11. Lubricate machine at intervals specified in

Never attempt to service or charge the battery while it  
is installed on the SCRAMBLER. Shield the positive  
terminal with terminal cover located on battery  
harness. This prevents metal from touching the  
positive terminal, which could cause sparks. Cables  
must be connected to battery terminals in the proper  
position as shown. 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.  
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.

Section 4 - ADJUSTMENTS & REPAIR  
4.5.6. BATTERY TESTING  
WARNING  
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.  
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.  
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.  
IMPORTANT: DO NOT place anything in new battery  
other than specified electrolyte.  
WARNING  
DO NOT OVERFILL! DO NOT attempt to charge  
battery while installed on the SCRAMBLER. DO NOT  
use “BOOST” chargers on the battery.  
4.6 MOTION CONTROL ADJUSTMENTS  
4.6.1. Neutral Adjustments  
When the machine is on a flat level surface and motion  
control levers are in their neutral or neutral lock  
positions, there should be no machine movement. If  
movement is present, adjustment must be made to left  
and/or right transmission control rods (located to the left  
and right of the operator seat, under the control panels):  
1. Remove the hair pin and washer securing the  
rod fitting to the Motion Control Lever pivot bracket.  
See Figure 4.15. Pull fitting end out from bracket.  
2. Turn fitting clockwise one turn if machine moves  
in reverse, or counterclockwise if machine moves  
forward.  
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.  
3. Replace fitting into hole, securing with washer  
and hair pin.  
4. Start the machine. With motion control levers  
left in their neutral lock positions, disengage the  
WARNING  
parking brake and check for movement.  
If  
Shield the positive terminal with terminal cover  
located on battery harness. This prevents metal  
from touching the positive terminal, which could  
cause sparks.
