Assembly Instructions14SETUP INSTRUCTIONSWalker Mowers are shipped partially assembled.After uncrating the tractor and mower deck, initialsetup is required.NOTE: During the process of unpacking, any dam-aged or missing parts should be noted and reportedto the delivering carrier immediately (put in writingwithin 15 days). The carrier will provide directionsfor proceeding with a claim to receive compensationfor damage.Tire Installation (Tractor)• Install the drive tires using the eight (8) lug boltsthat are supplied with the owner’s packet of materi-als. Drive tires are 18 x 8.50-10, 4-ply; rear tire is2.80/2.50-4 Pneumatic (4-Ply).• Check and adjust the inflation of the tires. Thetire inflation recommendations are:Drive = 15 PSI (103 kPa)Rear = 20 PSI (137 kPa)Battery ServiceThe battery is a completely sealed, non-serviceablebattery.IMPORTANT: Make sure battery is securelymounted in the frame. A loose battery may causedamage to the case resulting in acid leakage and se-vere damage to the machine. A hazard may be cre-ated by damage to critical working parts and safetysystems.Battery LocationBattery ChargingLimit initial charging current to 1000mA. Charge un-til battery voltage (under charge) reaches 14.40 to14.70 volts at 68°F (20°C). Hold at 14.40 to 14.70volts until current drops to approximately 50mA.Battery is fully charged under these conditions, andcharger should be disconnected.NOTE: Due to the self-discharge characteristics ofthis type of battery, it is imperative that it be chargedafter 6-9 months of storage, otherwise permanentloss of capacity might occur as a result of sulfation.Ref. EngineFront of MowerDANGERBATTERIES PRODUCE EXPLOSIVE GASES• Charge the battery in a well-ventilatedarea, so that gases produced while charg-ing can dissipate.• Keep sparks, flames, and smoking mate-rials away from the battery at all times.• Make sure the battery charger is unplug-ged before connecting or disconnectingcables to the battery.
