Section 4 - REPAIR & ADJUSTMENTS
WARNING
DO NOT attempt any maintenance, adjustments or service with engine and blade running. STOP engine and blade. Disconnect spark plug wire and secure away from spark plug. Engine and components are HOT. Avoid serious burns, allow sufficient time for all components to cool. DO NOT attempt to service or charge the battery while it is installed on the machine.
4.5. BATTERY SERVICE 4.5.1. BATTERY SERVICE
The battery supplied with the electric start model mowers is a sealed lead acid type battery. After initial activation the battery is sealed. No fluid level maintenance is required. DO NOT attempt to check or adjust fluid level in battery.
1.Remove battery.
2.Place battery in a well ventilated area on a level surface.
3.Slow charge battery at 1 amp for 10 hours.
4.If battery will not accept charge or is partially charged after 10 hours of charging at 1 amp, replace with new battery.
4.5.2. BATTERY STORAGE
If mower is to be stored, it is recommended the battery be removed, charged and stored.
1.Remove battery. Refer to Section “BATTERY REMOVAL”.
2.Perform battery service.
3.Bring battery to full charge, if required.
4.Store battery in an area away from the machine on a wood surface. DO NOT STORE BATTERY ON A CONCRETE SURFACE.
WARNING
DO NOT over fill battery with electrolyte. Shield the positive terminal with terminal cover located on battery harness. This prevents metal from touching the positive terminal which could cause sparks. 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 walk behind. DO NOT use “BOOST” chargers on the battery.
4.4.5.BATTERY TESTING
The charge condition of a battery can be estimated by using a voltmeter. The voltage readings indicate the state of charge. Record the voltage at the battery terminals. Use the “BATTERY CONDITION CHART” below to determine the state of charge. Slow charge the battery as required to bring to full charge.
4.4.6. NEW BATTERY PREPARATION
Snapper, through your local authorized Snapper dealer, provides replacement battery kits. The kit includes a battery, hardware, harness, electrolyte and instructions. The electrolyte (acid) is a very dangerous, corrosive and poisonous liquid. Follow very carefully all instructions and warnings provided with the kit. Contact your Snapper dealer for assistance.
