LOWER/FLOAT – ELECTRICAL

System Response

NOTE: For units with the accessory Scrape Maxx 
down force kit, see that section below.

1.  Verify that the POWER switch is in the plow 

position.

2.  By activating the LOWER function on the cab 

control, the control sends a signal to the plow 
module to complete the ground path for the 
electrical circuit, activating solenoid cartridge 
valves S1 and S4.

3.  With the weight of the snowplow on the 

rod end of the lift ram and the S1 cartridge 
valve shifted, the lift ram extends. Hydraulic 

fl

 uid is pushed out of the rod end through 

the activated S1 through the quill, and then 
returned to the reservoir. At the same time 

fl

 uid is drawn from the reservoir through the 

activated S4 into the base of the ram, S4 will 
close after the lower button is released.

NOTE: When the FLOAT mode is active, the S1 
cartridge stays open until the RAISE function is 
activated.

NOTE: Battery voltage is supplied to the plow 
module, motor relay and the 9 solenoid coils when 
the snowplow is connected to the vehicle.

 WARNING

If Scrape Maxx™feature is ENABLED and 

vehicle key is ON, the hydraulic unit can 

turn on temporarily without notice, if the 

control has been placed in the LOWER 

mode without any further control input.
