Ranger Products Professional RFJ-3TP, Installation And Operation Manual

BEFORE ATTEMPTING TO RAISE ANY VEHICLE, 

CHECK VEHICLE SERVICE MANUAL FOR  

RECOMMENDED LIFTING POINTS.

OPERATION: 

1.  To Raise Load: 

Close release valve tightly by  

twisting Handle clockwise. 

DO NOT OVERTIGHTEN. 

Position jack under load so that saddle will contact  

load firmly and load is centered so it cannot slip.  

Operate jack handle until saddle approaches the  

load. Once again, check to see that saddle is  

correctly positioned. Raise load to desired height. 

Place jack stands of appropriate capacity  

under the vehicle.  

DO NOT CRAWL UNDER VEHICLE WHILE 

LIFTING VEHICLE OR PLACING 

OR REMOVING JACK STANDS! 

1.  Place jack stands at vehicle manufacturer’s  

recommended lift areas that provide stable support  

for the raised Vehicle. Once jack stands are  

positioned, open the release valve 

VERY SLOWLY

(by twisting the Handle counter clockwise.)  

Lower the load to rest on the jack stands. Then,  

make sure that the release valve on the jack is  

closed tightly (twist the Handle clockwise). 

2.  To lower load: 

Re-check to make sure release  

valve is tightly closed (twist the Handle clockwise). 

Then, operate the jack handle until the load is raised 

enough to remove the jack stands. 

Once jack stands are removed, open release valve very 

slowly to lower the vehicle (twist the Handle counter 

clockwise). Lower jack completely so that the vehicle is 

securely resting on the ground and that jack no longer 

makes contact with vehicle. 

Keep hands or feet away from the hinge mechanism 

of the jack. 

MAINTENANCE 

When adding or replacing hydraulic fluid, always use a 

quality hydraulic fluid. DO NOT use brake fluid, alcohol, 

detergent motor oil, dirty oil or any fluid other than quality 

hydraulic fluid. Improper fluids can cause internal 

damage to the jack and improper or unsafe operation. 

ADDING HYDRAULIC FLUID 

With the saddle fully lowered and the jack on level 

ground, remove the filler screw. Hydraulic fluid should be 

filled to the level of the filler screw hole. If the level is 

below this hole, add hydraulic fluid as needed. 

LUBRICATION 

All moving joints require lubrication often. Lightly grease 

saddle post and saddle bottom. Remove handle and 

grease the lower end of handle where it rotates in the 

handle socket. Oil all lift arm linkages, front wheels and 

rear casters.
