Pump Drive
Check Oil Level
 |
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. |
 |
| NOTICE |
|---|
Overfilling can cause the pump drive to overheat. |
- 1. Unlatch and open the right rear access door.
- 2. Remove the oil level plug. The oil level should be to the bottom of the plug opening.
- 3. If necessary, remove the oil fill plug and add oil.
- 4. Clean and install the plugs. Close the access door.
Hydraulic System
Check Oil Level
|
At operating temperature, the hydraulic tank is hot and under pressure. Hot oil can cause burns. Remove the fill cap only when the engine is stopped, and the cap is cool enough to touch with your bare hand. Remove the fill cap slowly to relieve pressure. |
|
BACKHOE - Position the bucket flat on the ground, with the stick cylinder fully extended.
CLAMSHELL - Position the clamshell open on the ground, with the stick cylinder fully extended.
- 1. The engine must be stopped and the hydraulic oil cool. The hydraulic and directional lock must be engaged.
| NOTICE |
|---|
An improper hydraulic oil level can result in machine damage. |
- 2. Unlatch and open the right side front access door.
- 3. Maintain the oil level to the FULL mark in the sight gauge.
- 4. To add oil, remove the fill cap slowly to relieve pressure.
- 5. Replace the cap gasket if it is damaged. Install the fill cap.
Close and secure the access door.
Batteries
Check Electrolyte Level
|
Batteries give off flammable fumes that can explode. Do not smoke when observing the battery electrolyte levels. Electrolyte is an acid and can cause personal injury if it contacts skin or eyes. Always wear protective glasses when working with batteries. |
|
At the proper charging rate, in a moderate climate, a battery should not require more than 30 cc (1 ounce) of water per cell per week.
- 1. Unlatch and open the left side rear access door.
- 2. Clean the top of the batteries with a clean cloth. Keep the terminals clean and coated with petroleum jelly.
- 3. Inspect the electrolyte level in each battery cell. Maintain the level to the bottom of the fill openings with distilled water. If distilled water is not available, use clean drinking water.
- 4. Close and secure the access door.
