Use the right tool for the job. There are certain applications for which this Level-
ing Scissor Jack was designed. It will do the job better and more safely at the rate for
which it was intended. Do not modify this Jack and do not use this Jack for a purpose
for which it was not intended.
Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving
parts. Wear restrictive hair covering to contain long hair.
Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across a Leveling Jack under a load.
Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. The handle must be kept clean,
dry, and free from oil and grease at all times.
Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any part
that is damaged should be properly repaired or replaced by a qualified technician.
Replacement parts and accessories. When servicing, use only identical replacement
parts. Use of any other parts will void the warranty. Only use accessories intended for
use with this tool. Approved accessories are available from Harbor Freight Tools.
Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
Do not operate tool if under the influence of alcohol or drugs. Read warning labels
if taking prescription medicine to determine if your judgment or reflexes are impaired
while taking drugs. If there is any doubt, do not operate the tool.
Stand clear of the Leveling Jack when attempting to level any trailer or RV.
Never exceed the Jack’s capacity of 5,000 lb. Check the trailer or RV’s manual to
determine the actual gross weight before attempting to level it. This Jack’s weight
capacity is 5,000 lb. only between 13-3/4” and 23-1/2”; the weight capacity dras-
tically reduces as the height drops below this level. Do not apply a load to this
jack below 13-3/4” in height.
Never stand on the Jack and never have people or pets in the trailer or RV you
are attempting to level.
Place the Leveling Jack on a flat, level surface. Only use this Jack on a stable,
clean, dry surface that is capable of sustaining the weight of the Jack and the load it
is stabilizing.
Stabilize the load. Ensure that the load remains stable at all times. Do not move the
load while it is on the Leveling Jack.
Block all of the wheels when leveling an RV or trailer.

Attach Jack to the frame of the RV or Trailer using two c-clamps (not included) or two
vise grips (not included). Close the Jack using the Handle Wrench (16) to check the
frame location. Make sure the Jack will clear any chassis components nearby.
Open the Jack enough to touch the ground. Recheck the location on the frame and

BOLT-ON INSTALLATION
WARNING! BEFORE DRILLING HOLES, CHECK FOR ANY CHASSIS COMPO-
NENTS WHICH MAY BE INSIDE THE FRAME. LOOK FOR ELECTRICAL LINES
AND WIRES, GAS TANK, GAS LINES, WATER AND HOLDING TANKS, GENERA-
TOR FUEL LINES AND WATER HEATER LINES. MAKE SURE AREA IS CLEAR
OF THESE COMPONENTS BEFORE DRILLING.
Hold the Jack against the frame and using the Mounting Brackets (9) as a template, mark
the locations of the 8 mounting holes on the RV or Trailer frame. Remove the Jack.
Use a center punch (not included) and hammer (not included) to mark the center of
each hole.
Use a drill (not included) to make a pilot hole 1/8”. Then use a 5/16” drill bit (not in-
cluded) to complete each hole. Use eight 3/8” tapping screws (not included) with eight
lock washers (not included) to attach the Jack to the frame.
WELD-ON INSTALLATION
Refer to “Installation” and steps 1 and 2 under “Bolt-on Installation” on pages 4 and 5
of this manual.
Weld at least four 1” welds on the Jack Mounting Brackets (9) when attaching to the
frame.
OPERATION
TRAILERS, TRAVEL TRAILERS AND 5TH WHEELS
Park on level ground.
Level trailer (travel trailer, 5th wheel) front and back with small carpenter’s level (not in-
cluded), or round bubble level (not included). Place leveling blocks (not included) in front
of one tire on trailer. Slowly pull forward to drive the trailer up onto the blocks. When
the trailer is level, stop and block all tires to keep from rolling forward or backward.
Using Handle Wrench (16) lower the Scissors Jack on the lowest side first to get level.
Use Jacks on opposite sides for best stabilization.
After Jack makes firm contact with ground, turn Handle Wrench (16) twice to insure
Jack will not loosen from trailer during use.
NOTE: When RV or trailer will not be moved for several days, periodically check Jacks to be
sure they have not worked loose.
