CONTROL GP-TRANSMISSION 1492331 - Caterpillar

Burner Control
Burners are provided for preheating the screed plates. If the screed is not preheated, asphalt will stick to the metal surfaces causing scuffing of the mat. Another way of preheating the screed is to lay the screed on the hot mix before paving. If the tractor is equipped with an additional burner pump switch, it must be in the OFF position for the burner timer to work.1. Hold the glow plug switch in the GLOW position for 15-30 seconds. This will heat up the glow plug so that the fuel will light when it is turned on.2. The blower switch is the same as the glow plug switch. When the glow plug switch is released, it will automatically return to the blower position. This causes air to be forced down from the burner chamber causing turbulence and creating optimum fuel efficiency and even distribution of the resulting heat.Thickness Control Screws
The thickness control screws are used to introduce the angle of attack into the screed. There is one thickness control screw located on each end of the screed. The adjustment of the thickness control screws and the start up procedure are discussed in the "Setup Section" of this manual.Hydraulic Strikeoff (HSO) (If Equipped)
Height Adjuster
The height adjuster moves the HSO'S up or down to keep the screed plate level with the main screed trailing edge when the attack angle is adjusted.There is a power option available. See your Caterpillar dealer.Sloper Control
1. The HSO'S adjust down from 0 to 8°.2. Turn the sloper crank clockwise, (as you view it), to put in the slope. The extender then pivots down.3. The HSO'S can be adjusted while paving. This does not change the main screed width.A power option is available for sloping the extenders. See your Caterpillar dealer.Hydraulic Strikeoff (HSO) Width Switch
The Extender width switch moves the HSO in and out as desired to achieve the overall desired paving width. The right HSO is controlled by the Extender width switch in the right screed control box. The left HSO is controlled by the Extender width switch in the left screed control box. Additional switches may be located on the tractor. See the tractor Operation Manual.Crown Control
No leading edge crown is required for the Pavemaster B screed.The crown control adjusts the screed to produce the desired contour of the finished pavement. Turn the control handle clockwise to increase crown to the desired setting. Make sure the crown control lock is engaged so the setting does not change while paving.A power option is also available for the crown control. See your Barber-Greene dealer.Feeder Gain
The function of this system is to maintain a constant head of material in the feeder screw chamber by changing the speed of the feeder and the screw in proportion to the direction of the position of the sensor paddle. The feeder control system consists of the following:* Feeder Control Pots - The feeder control pots, with sensor paddles, are located on mounting shafts near the left and right hand outboard
