Check the Batteries
Proper battery condition is essential to good engine
performance and operational safety. Improper fluid
levels or damaged cables and connections can
result in engine component damage and hazardous
conditions.
Electrocution hazard. Contact with hot or live
circuits may result in death or serious injury.
Remove all rings, watches and other jewelry.
Bodily injury hazard. Batteries contain acid.
Avoid spilling or contacting battery acid.
Neutralize battery acid spills with baking soda
and water.
Note: The controls battery is below the start
battery.
1 Put on protective clothing and eye wear.
2 Be sure that the battery cable connections are
tight and free of corrosion.
3 Be sure that the battery hold-down bar is secure.
4 Remove the battery vent caps.
5 Check the battery acid level. If needed,
replenish with distilled water to the bottom of the
battery fill tube. Do not overfill.
6 Install the vent caps.
Note: Adding terminal protectors and a corrosion
preventative sealant will help eliminate corrosion on
the battery terminals and cables.
Check the Hydraulic Oil Level
Maintaining the hydraulic oil at the proper level is
essential to machine operation. Improper hydraulic
oil levels can damage hydraulic components. Daily
checks allow the inspector to identify changes in oil
level that might indicate the presence of hydraulic
system problems.
1 Be sure that the boom is in the stowed position,
then visually inspect the sight gauge located
on the side of the hydraulic oil tank. Add oil as
needed.
Result: The hydraulic oil level should be within
the top 5 cm of the sight gauge.
