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
the oil level that might indicate the presence of
hydraulic system problems.
1 Be sure that the engine is off and the boom is in
the stowed position.
2 Visually inspect the sight gauge located on the
side of the hydraulic oil tank.
Result: The hydraulic oil level should be
between the two marks on the decal next to the
sight gauge. Add oil as needed.

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.
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 in
place and 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.
