TURBOCHARGER GP 7C8676 - Caterpillar

Pile the load on the high side of the slope for easier backfilling. Use the bucket to aid when stuck in the excavation. Dump the bucket and apply down pressure to raise the front wheels from ditch. Tilt the bucket back, move direction control to reverse and accelerate engine to move backward.Multipurpose Clam Bucket
To use the bucket as a clamp:Open the bowl and position the bucket over the material to be loaded. Lower the bucket and close the bowl. The Multipurpose Bucket can also be used for increased dump height, or when unloading sticky material.Position the bucket over the dump area and open the bowl. Bucket used as a dozer:To use the blade for dozing, open the bowl. Maintain a level cut. Bucket used as a scraper:Raise the bowl slightly and position the bucket as for dozing. When loaded, tilt the bucket back and close the bowl. The bucket is dumped in the normal tilt forward position.Backhoe Operation
Backhoe Bucket Positions
Install braces and pins in the following positions according to desired operation. Use position (1) for maximum load retention for loading trucks.Use position (2) above for best digging. This position gives more bucket breakout force. This position also gives more bucket curl out to dig deep vertical excavations.Preparing to Operate Backhoe
1. Lower the loader bucket until the front wheels are slightly off the ground. When conditions permit, tilt loader bucket forward to the dump position to reduce sliding of the vehicle.2. Move the speed and directional control levers to NEUTRAL and engage NEUTRAL LOCK.3. Engage the parking brake.4. Turn the seat to face the backhoe.5. Lower the stabilizers until the rear tires are slightly off the ground.6. Disengage the boom and swing lock.Dig with backhoe uphill on slopes if possible.Dump load uphill when possible to avoid tipping.Level the backhoe with stabilizers to allow machine to be in level position before digging.Backhoe Digging
1. Bucket digging start position. 2. Close the bucket slowly and move the stick in at the same time, for maximum performance.Keep the bucket teeth at the proper digging angle as shown for best penetration. This will help prevent bucket from just scraping the ground.Bucket penetration in hard packed ground can be increased, by applying down pressure with the boom. Move boom down while closing bucket. 3. Close the bucket completely and move the stick and bucket out from machine slightly, while lifting bucket from excavation.This will provide a cleaner trench and allow excess material to fall back into excavation. This will also avoid build-up of material between stabilizers and excavation. 4. Swing the bucket to the side and dump load while approaching the pile.5. Return to the excavation. After the bucket is dumped, the stick and bucket should be close to the digging position.
Avoid stopping the bucket against the excavation or dump pile to prevent early pin and bushing wear.Do not backfill by using swing cylinders and bucket sides. Backhoe damage could result.
6. Backfill by lifting bucket over dump pile. Pull in bucket and lift boom evenly.Extendable
