4.5.3.1— Engine Oil Recommendations
All oil should meet minimum American Petroleum Institute (API) Service Class SJ, SL or better. Use no special additives.
See B of Figure 4-1. Select the oil viscosity grade according to the expected operating temperature.
• Above 32° F (0° C), use SAE 30
• Between 40° F and -10° F (4° C and -23° C), use 10W-30
• For all temperature ranges, use Synthetic 5W-30
4.6 — Schedule A Maintenance
NOTE: Perform Schedule A maintenance every two years or after 500 hours of service, whichever comes first.
4.6.1— Check Battery Condition/Fluid Level
4.6.1.1— Check Condition and Clean
1. Remove front access panel.
2. Verify that top of battery is clean and dry. Dirt and electrolyte on top of the battery can cause battery to self-dis-
charge. Clean battery top with a solution of baking soda (sodium bicarbonate) and water (5 teaspoons baking
soda per quart or liter of water). When solution stops bubbling, rinse off the battery with clean water.
3. Clean cable clamps and battery terminals using a wire brush or sandpaper to remove any oxidation.
4. Inspect battery screws, clamps and cables for breakage, loose connections and corrosion. Tighten and clean as
necessary.
5. Check the battery posts for melting or damage caused by over tightening.
6. Inspect battery for discoloration, raised top or a warped or distorted case, which might indicate that the battery
has been frozen, overheated or overcharged.
7. Inspect the battery case for cracks or leaks.
8. Check the battery fluid level of unsealed batteries. See Subsection 4.6.1.2—Check Fluid Level.
9. Check the battery state of charge. See Subsection 4.6.1.3—Check State of Charge.
10. Replace battery if damaged or unable to hold a charge. See Subsection 4.6.1.4—Battery Replacement.
4.6.1.2— Check Fluid Level
Check the fluid level of unsealed batteries. If necessary, fill with distilled water only. DO NOT use tap water.
4.6.1.3— Check State of Charge
Check the state of charge using a Digital Multimeter. Recharge and retest if state of charge is below manufacturer's
recommendations. Replace battery if necessary.
4.6.1.4— Battery Replacement
Removal
Always disconnect the negative battery cable first. If the positive cable should contact ground with the
negative cable installed, the resulting sparks may cause a battery explosion which could result in seri-
ous injury.
1. Remove battery negative cable (black) from battery negative (-) terminal.
2. Remove battery positive cable (red) from battery positive (+) terminal.
3. Remove battery from battery tray.
Installation
1. Install battery onto battery tray.
Always connect the positive battery cable first. If the positive cable should contact ground with the
negative cable installed, the resulting sparks may cause a battery explosion which could result in seri-
ous injury.
