Section 2 - OPERATING INSTRUCTIONS2.7. REVERSE LOCKOUT MECHANISMData indicates that tragic back-over accidents occureach year. These accidents usually involve unsupervisedchildren. Many times these children have been givenrides on the machine and have been trained to view thispotentially dangerous piece of machinery as fun ratherthan being taught how to avoid danger.This riding mower has a Reverse Lockout Mechanism.This mechanism prevents the mower from being shiftedinto reverse with the blades running. To shift into reverseyou must first stop the blades and then shift to reverse. Itis our recommendation that this mechanism remainfunctional and the operator of this equipment develop thehabit of never backing up with the blades running. As theSafety Instructions Indicate, DO NOT operate blades inreverse. STOP BLADES, LOOK AND SEE BEHINDAND DOWN for children, pets and hazards beforeand while backing.We realize that this could cause a change to yourprevious mowing method but we encourage you to adjustto this new system. Do not defeat the Reverse LockoutMechanism.If you operate your mower near roadways or useattachments that require quicker shifting to reverse,there is an override lever provided. This lever can bepushed and held before engaging the blades and willallow reverse operation until the blade switch is pushedin to the “OFF” position, at which time the system willreturn to its Reverse Lockout mode. This feature shouldnever be selected unless you are absolutely sure that nochildren or others are present in the mowing area andthat all children are away and supervised by aresponsible adult.2.7.1. Reverse Lockout Mechanism Override1. Stop machine. Stop blades.2. Depress and hold Override Lever.3. Pull blade switch “OUT” to engage blade.4. Release Override LeverWARNINGLOOK and SEE behind and down for children, petsand hazards before and while backing.IMPORTANT! DO NOT use the Reverse LockoutMechanism Override as the normal operating mode. Toreturn to the Reverse Lockout Mechanism mode,disengage (STOP) blades by pushing blade switch in tothe “OFF” position. The Override will reset to ReverseLockout.2.7.2. Check the Reverse Lockout MechanismBefore each use, check the Reverse LockoutMechanism for proper function. The followingprocedure requires the operation of the engine andblades. Before proceeding, Read, Understand, andFollow all Safety Instructions and Warnings in thismanual and on the machine.1. Complete Pre-Start Checklist.2. Move machine to clear open area. DO NOTallow children or others in area.3. Start engine.4. Pull blade switch “OUT” to engage blades.5.

If acid is spilled on battery, bench, orclothing, etc., Flush with clear water and neutralizewith baking soda.4.5.3. BATTERY SERVICE1. Remove battery. Refer to Section “BATTERYREMOVAL”.2. Place battery in a well ventilated area on a levelsurface.3. Using distilled water, refill cells as required to covercell plates of which can also be visualized through theplastic battery case.4. With cell caps removed, connect battery charger tobattery terminals. Red to positive (+) terminal and blackto negative (-) terminal.5. Slow charge battery at 1 amp for 10 hours.6. If battery will not accept charge or is partially chargedafter 10 hours of charging at 1 amp, replace with newbattery.4.5.4. BATTERY STORAGEWhen out of season, it is recommended the battery beremoved, charged and stored.1. Remove battery. Refer to Section “BATTERYREMOVAL”.2. Perform battery service.3.

Section 4 - ADJUSTMENT & REPAIRWARNINGDO NOT OVERFILL! Never attempt to service orcharge the battery while it is installed on the machine.DO NOT use “BOOST” chargers on the battery.4.5.5. BATTERY TESTINGThere are two types of battery tests: Unloaded andLoaded. The unloaded test is the procedure that willbe discussed. It’s the simplest and most commonlyused. An unloaded test is made on a battery withoutdischarging current. To perform unloaded testing,check charge condition using either a hydrometer orvoltmeter.1. Using a voltmeter, voltage readings appearinstantly to show the state of charge. Remember tohook the positive lead to the battery’s positiveterminal, and the negative lead to the negativeterminal.2. A hydrometer measures the specific gravity ofeach cell. The specific gravity tells the degree ofcharge; generally, a specific gravity of about 1.265 to1.280 indicates full charge. A reading of 1.230 to1.260 indicates the battery should be charged. Thechart on the next page shows the charge level asmeasured by syringe float hydrometer, digitalvoltmeter and five ball hydrometer.4.5.6. NEW BATTERY PREPARATION1. Remove battery from carton.2. Place battery in a well ventilated area on a level nonconcretesurface.3. Remove battery cell caps. Fill cells as requiredwith electrolyte (purchased separately) to proper level.Fill to 3/16” above cell plates. Filling battery withelectrolyte will bring the battery to 80% charged state.4. With cell caps removed, connect battery charger tobattery terminals; RED to positive (+) and BLACK tonegative (-) terminal.IMPORTANT: 3/16” above cell plates is the recommendedlevel. DO NOT place anything in battery other than specifiedelectrolyte.5. Slow charge the battery at 1 amp for 2 hours tobring the battery to full charge.6. After charging, check level of electrolyte and addas needed to bring level to 3/16” above cell plates.7. Reinstall cell caps.8. Slide battery partially into battery housing.9. Connect positive (+) cable (red) first, from wiringharness to the positive terminal (+) on battery using boltand nut provided in hardware bag. Connect negative (-)cable (black) last, to negative terminal (-) on batteryusing bolt and nut. Apply a small amount of grease overterminals to prevent corrosion.10. Insert battery completely into battery housing.11. Reinstall seat assembly.WARNINGShield the positive terminal with terminal coverlocated on battery harness. This prevents metal fromtouching the positive terminal, which could causesparks. Cables must be connected to batteryterminals in the proper position. RED (Positive) cablemust go to the ( + ) terminal. BLACK (Negative) cablemust go to the ( - ) terminal.4.5.7.
