Page 22 PLOWING OPERATION Operating Class Revolution Wing Movement and Use The Sno-Way 29RVHD Series plow is specifically Extend designed for heavy commercial applications on 3/4 ton, 1 ton, and other vehicles with a GVWR up to 20,000 lbs. To extend the revolution wings the forward button, located on the hand pendant, is depressed (See Figure 3-1).
Page 23 Straight Scoop For a straight scoop, the main plow wings are to be extended outward, and both right and left revolution wings extended (See Figure 3-3). Figure 3-3 Straight Scoop Position Transport To transport the plow down the road, to not exceed width limits according to local ordinances, the main plow wings are to be retracted, and the revolution wings fully extended, or wrapped forward into the main plow face (See Figure 3-4).
Page 24 Serious head or neck injuries can result from sudden stops or coming into contact with tree branches, signs The 29RVHD Series will partially block the plow lights when fully raised, especially if a deflector or other stationary objects.

Improper main system Using a 3000 psi gauge plumbed into the gauge port (GP), run plow over pressure relief valve relief.
Page 29 Test the control receiver to see if there is a ground signal sent to the lower coil (B) without activation coil (B) without activation. This can be done using a Sno-Way control tester (99101463). If you do not have a test box remove the two wires off of the (B) coil and check to see if the blue with the white trace wire has a ground signal coming from it.
