Look at the Oil Level
Backhoe - Position the machine on level ground, with the stick and cylinder fully extended and the bucket flat on the ground. Front Shovel - Position the machine on level ground, with the stick cylinder fully extended and the bucket flat on the ground.1. Check the level with the hydraulic oil cold and the engine stopped. 2. Open the front access door on the right side of the machine. 3. Maintain the oil level to the FULL mark in the sight gauge. 4. To add oil, open the access cover on the top panel. 5. Remove the fill cap slowly to relieve pressure.6. Replace the cap gasket if it is damaged. Install the fill cap and close the access cover.Swing Bearing
Lubricate the Fitting
Fitting located in the cab. Rotate the upper structure 720° (two full rotations). Stop at each 90° (1/4 turn) and lubricate the bearing through the grease fitting. Lubricate until grease can be seen flowing from behind the bearing seal. Lubricate Every 10 Service Hours or Daily when operating in water or abrasive material.Pump Drive
Check the Oil Level
Position the machine on level ground with the equipment lowered. The hydraulic and directional lock lever must be in the locked position and the engine stopped. 1. Open the right access door on the rear of the machine. 2. Maintain the oil level to the FULL mark on the dipstick. Add oil if necessary. Overfilling can cause overheating of the pump drive.3.

Lubricate the Fittings
Lubricate four fittings at the head end of the boom cylinders. Lubricate the right lower boom (foot) bearing through one fitting on the boom.
To insure proper lubrication of the boom foot pins, grease should be applied first with the boom raised and any attachment suspended, then with the boom lowered and the attachment resting on the ground with a slight down pressure. If the boom foot pins are not properly greased, the service life of these pins is proven to be dramatically reduced.
Lubricate the left boom (foot) bearing, two boom cylinder rod end bearings and stick cylinder head end bearing at the block on top of the boom. Total of four fittings. Lubricate the stick to boom bearings through two fittings on the stick. Lubricate one fitting at the rod end of the stick cylinder. Lubricate two fittings on the bucket cylinder. Lubricate two idler link bearings and two bucket bearings through four fittings located on the stick. Lubricate four fittings on the power link. Lubricate Every 10 Service Hours or Daily when operating in water or abrasive material.
