Section 6 - Maintenance
Quarterly Checklist
The following maintenance should be done every 3 months (quarterly) or 250 hours of operation.
B-1 Inspect the Battery
• Tools will be required to perform this procedure.
• New parts will be required to perform this procedure.
Proper battery condition is essential to good machine performance and operational safety. Improper
fluid levels or damaged cables and connections can result in component damage and hazardous
conditions.
Electrocution / burn hazard. Contact with electrically charged circuits
could result in death or serious injury. Remove all rings, watches and
other jewelry.
Bodily injury hazard. Battery contain acid. Avoid spilling or contacting
battery acid. Neutralize battery acid spills with baking soda and water.
1. Put on protective clothing and eye wear.
2. Be sure that the battery cable connections are free of corrosion.
Note:
Adding terminal protectors and a corrosion preventative sealant will help eliminate corrosion on
the battery terminals and cables.
3. Be sure that the battery retainers and cable connections are tight.
4. Fully charge the battery. Allow the battery to rest 24 hours before performing this procedure to
allow the battery cells to equalize.
5.
Remove the battery vent caps and check the specific gravity of each battery cell with a
hydrometer. Note the results.
6.
Check the ambient air temperature and adjust the specific gravity reading for each cell as
follows:
• Add 0.004 to the reading of each cell for every 10°F (5.5°C) above 80°F (26.7°C).
• Subtract 0.004 from the reading of each cell for every 10°F (5.5°C) below 80°F (26.7°C).
• Result:
All battery cells display an adjusted specific gravity of 1.217 or higher. The battery is
fully charged. Proceed to step 10.
• Result:
One or more battery cells display a specific gravity of 1.217 or below. Proceed to
step 7.
7. Close the battery vents. Perform an equalizing charge OR fully charge the battery and allow the
battery to rest at least 6 hours.
8.
Remove the battery vent caps and check the specific gravity of each battery cell with a
hydrometer. Note the results.
9.
Check the ambient air temperature and adjust the specific gravity reading for each cell as
follows:
• Add 0.004 to the reading of each cell for every 10°F (5.5°C) above 80°F (26.7°C).
• Subtract 0.004 from the reading of each cell for every 10°F (5.5°C) below 80°F (26.7°C).
• Result:
All battery cells display a specific gravity of 1 .277 or greater. The battery is fully
