HUB AS 1094730 - Caterpillar

Do not push load a scraper which is equipped with an auger attachment.
Load your scraper in the direction of the fill.
When you arrive at the cut, reduce travel speed by using the service brake or the retarder. The transmission will downshift automatically. Most loading is done in second gear.
Move the switch for the cushion-hitch to the OFF position in order to make a smooth cut.
Move the ejector to the rear of the bowl.Note: The ejector should always be moved to the rear of the bowl at the finish of dumping the load. The chance of cylinder damage due to bouncing will be reduced.
Engage the differential lock.Note: Do not engage the differential lock control while a wheel is spinning. Do not turn the scraper with the differential in the LOCK position.
Open the apron partially.Note: Keep the apron open only far enough to prevent material from piling in front of the lip or from falling out of the bowl.
Engage the auger. The auger must be engaged at least 5 seconds before loading begins. Note: The auger must be engaged during loading and during unloading.Note: Do not allow the engine speed to drop. Engine speeds below 1700 rpm will reduce the speed of the auger.
When the transmission downshifts to the desired speed, move the transmission hold control to the ENGAGED position.
Maintain the engine rpm within the operating range. Start the cut.
Lower the bowl to a cutting depth that is efficient for loading the material.Note: The cut should be shallow enough to allow the machine to move at a constant speed. If the cut is too deep, the engine may lug. Excessive tire slippage may also occur.Decrease the cutting depth if the engine begins to lug or if the tires slip.Use first speed if more torque is required at the wheels.
Drive the machine as straight as possible during loading.
Do not overload the bowl. Overloading the bowl lowers machine efficiency.
When the bowl is full, raise the bowl as you drive forward. The cut will be smoother.
Close the apron. Move the apron control to the FLOAT position.
Disengage the auger.
Move the differential lock control to the UNLOCK position. Accelerate to travelling speed. Disengage the transmission hold control.
Move the switch for the cushion-hitch to the ON position in order to increase operator comfort.Note: When you are working, try to maintain a grade which is suitable for good drainage of water. Down time due to weather will be minimized.
Maneuver around large objects to load or unload. Driving over large objects may damage the transmission case.
Straddle Loading
Illustration 1 g00318694
For efficient loading, leave a ridge between the cuts.Note: The ridges should fit in the distance between the scraper tires.
On succeeding passes, pick up the ridges at a depth below previous cuts. This will leave ridges. Repeat the cycle until the finished depth is reached.
