General safety
instructions
Safely operating
the tool
WARNING: When using tools, basic safety precautions should
always be followed to reduce the risk of personal injury.
●Read all instructions before using this tool.
●Keep your work area clean. Cluttered areas invite injuries.
●Consider your work environment. Do not use the jack in damp,
wet, or poorly lit locations. Keep your work area well lit. Do not
expose the jack to rain.
●Be aware of other people. Do not use the tool near children or
animals. Keep children and animals away. Keep all visitors (in-
cluding children and animals) away from the work area. Do not let
visitors handle tools.
●Do not operate the tool if you are under the inuence of alco-
hol or drugs. Read warning labels on prescription and non-pre-
scription
medications to determine if a medication impairs your judgment or
reexes. If you have any doubts, do not attempt to use the tool.
●Stay alert. Pay attention to what you are doing, and use common
sense. Do not operate the tool when you are tired.
●Dress properly. Do not wear loose clothing or jewelry. They can
be caught in moving parts. Gloves and non-skid footwear are rec-
ommended when working outdoors. Wear protective hair covering
to contain
long hair.
●Use safety glasses. To prevent eye injuries, the tool operator
and all persons in the work area must wear safety glasses with
permanently attached, rigid, plastic, side shields. These safety
glasses must conform to ANSI 287.1 requirements.
●Do not alter the tool. Any alterations or modications to this tool
may result in dangerous conditions. Remember this tool is preci-
sion built to perform specic operations. Any alterations will void
the warranty.
WARNING: When using the Farm Jack, these safety precautions
also should be followed to reduce the risk of personal
injury.
●Do not overreach. Keep proper footing and balance at all times.
●Do not over-extend or over-work the tool. The tool does a bet-
ter and safer job at the rate for which it was intended.

●Use the correct tool. Do not force a small tool or an attachment
to do the work of a larger industrial tool. Do not use a tool for a
purpose for which it was not intended.
●Never stand on the tool. Standing on the tool could cause an
injury if the tool is tipped.
●Inspect the tool. Before using the tool, check for damaged parts.
A damaged handle or other part should be carefully checked to
determine if it will keep the tool from operating properly and per-
forming its intended function. Check for alignment and binding of
moving parts, broken parts, mounting, and other conditions that
may affect its operation.
●Maintain tools with care. Keep tools clean for better and safer
performance. Follow the instructions for lubricating, cleaning, and
replacing parts and accessories. Keep handles dry, clean, and free
from oil and grease.
●Use proper replacement parts. When servicing the tool, only use
identical replacement parts.
●Store tools not being used. When tools are not being used, store
them in a dry and high or locked place—out of children’s reach.
CAUTION: Improperly using this jack is highly hazardous. Read
these instructions before using the jack.
Make sure to:
●Visually inspect the jack. Check that all moving parts mate cor-
rectly
and that no visible cracks or bends are present on the handle or
rail.
●Stabilize the load to be lifted because the Farm Jack does not
stabilize
the load.
●Keep all visitors and children clear of the load being raised, low-
ered,
or pulled.
Important: Do not use a handle extender. All warranties are void if an
extender is used on the handle.

Lifting a load Refer to gure 1 while following these steps:
Step 1. Place the jack on a stable area to prevent shifting or slip-
ping.
Step 2. Put the reversing switch in the up position to raise loads.
Step 3. Place the jack’s lifting nose completely under the object you
want to lift. The ratcheting mechanism lets the lifting nose
rise, saving you from having to pump the handle.
Step 4. Slowly pump the handle to raise the load. Always keep a
rm grip on the handle while operating the jack.
Step 5. After the load is raised to the desired height, insert the 1/2
inch bolt (sold separately) through the hole in the steel rail
immediately below the lifting mechanism.
Step 6. Insert additional supports to make sure the load is properly
supported at the lift point to prevent shifting.
Figure 1 - Lifting and lowering loads with the Farm Jack
CAUTION: Follow these precautions while working with raised
loads:
●Never work under a raised load.
●Never push a lifted load off the jack.
●Never attempt to repair the jack when it is under a
load.

CAUTION:
(Refer to Step 5)
Dynamic Loading may
under certain circum-
stances create a situation
where the actual weight
being held or lifted is far
in excess of jack or bolt
capacity. DO NOT drop
weight onto the ling
nose, or allow sudden
motion of the jack lifting
nose, as this may shear
the 1/2” bolt or cause the
jack to fail.

Lowering a load
Maintaining the
Farm Jack
WARNING: When using tools, basic safety precautions should
always be followed to reduce the risk of personal injury.
Step 1. Put the handle in the upright position before tripping the re-
versing latch to lower the load.
Step 2. Place the reversing switch in the down position.
Step 3. Slowly pump the handle to lower the load.
Note: To lower loads one raised level at a time, the jack must be
loaded with 110 lb (50 kg) or more. Otherwise, the lifting nose
will drop.
●Keep the jack clean and oiled. The front and back of the rail must
be kept rust free.
●If any part of the jack fails, do not use until it is completely repaired
and checked by a professional.
