3. 

Mount winch to the vehicle using high strength cap  screw. It should be aligned and 

secured to a solid part of the vehicle (front or rear) where the full rated load will be 

evenly distributed.  

4. 

Connect  the  two-color  (positive)  battery  cable  from  the  directional  valve  to  screw-

down positive (+) terminal to the 12/24-volt battery. 

5. 

Please refer to installation illustration. 

Mounting The Balance Valve:

 

The  balance  valve  supplied  is  connected  to  motor.  Be  sure  the  balance  valve

’s 

installing direction meets hydraulic principle chart. Otherwise, the winch will not reach 

the rated line pull, and it is also dangerous for winch to power off the cable with heavy 

load. If this symptom happens, simply disconnect the balance valve: exchange the oil 

hole  between  hydraulic  motor  and  balance  valve,  while  your  winch  is  working  in  a 

different  direction;  change  A

C1,B

C2  into  A

C2,B

C1  and  reconnect  it.  If  your 

order includes the balance valve should be supplied, it will have been connected with 

the motor at the factory. 

Plumbing Connections: 

Keep all hoses away from any areas where heat may be considered too extreme such 

as an exhaust manifold or turbo. Lines should not be allowed to rub on any abrasive 

or  vibrating  surfaces.  In  some  applications,  90°fittings  on  the  directional  valve  and 

motor  or  balance  valve  are  necessary  to  make  hose  mounting  more  flexible.  After 

plumbing has been laid out on vehicle, install o-ring fittings supplied to valve. Torque 

tight.  Do  not  over  tighten  any  fittings.  Install  o-ring  fittings  on  Winch  Motor.  Torque 

tight.  Connect  any  hose  port  A  on  motor  or  port  V1  on  balance  valve  to  port  A  on 

directional valve, port B on motor or port V2 on balance valve to port B on directional 

valve,  port  P  on  directional 

valve  to  pump’s  high  pressure  port,  port  T  on  valve  to 

reservoir, if necessary Connect any hose port S on valve to steering box. Attach any 

o-ring or seal from vehicles original tube fitting to tube fitting.
