use and monthly for intermittent use.
Damaged jacks-any jack which appears to be damaged in any way or
deemed badly worm or operates abnormally-MUST BE REMOVED
FROM SERVICE UNTIL NECESSARY REPAIRS ARE MADE.
5. You must retain this manual and make it available to all persons
in need of the information contained herein.

OPERATING
INSTRUCTIONS:
1. To raise: close the release valve(turn the knob clockwise) then pump
the handle.
2. To lower: turn the release valve SLOWLY counter-clockwise. When
lowering the jack lift truck. It is important to keep the rate of lowering
under your control. Do not lower the fork lift until the area is free of
personnel, tools and equipment. Keep all body parts away from the
area wheels of the jack because they move backwards when
lowering.
3. We recommend that a vehicle be
raised by cradling a support
point in the notch at the end of
the lift arm. (Fig. 1-B) To
accomplish this , it is advisable
to attach a steel bar to the lower
surface capable of supporting
the load. The serrated pad can
be used to raise a vehicle with
flat underside. See Fig. 1-A (flat
surface must be parallel to the
floor before lifting)
4. Always position lift pad least 76mm inward toward the centre of
vehicle from the beginning of the flat surface (See Fig. 1-A). Never
push jack under the fork lift beyond the “red line” marked on decal
located on top of the lift arm (see NOTICE ② in PLACARD).
a. When lifting from the
side the jack should be
located nearer to the rear
wheels than the front. If
the fork lift seems to be
heavier at one end, lower
the jack and move it closer
to the heavy end to obtain
suitable balance.

b. When lifting from the end
place the HFJ-700A at the
centre of the fork lift truck.
Always chock the wheels at the
opposite end of the fork lift.
When lifting 3 wheeled lift trucks,
never lift the 2 wheeled end.
WARNING: Do not lift from the
end of the fork lift if the contact
surface is sloped or rounded(See
Fig.4)
WARNING: This is a lifting device
only！After lifting, load must be
immediately supported by
adequate stands. Failure to do so
may result in personal injury
and/or property damage.
WARNING: Care must be taken
not to tilt the vehicle more than
15°when using the serrated pad.
Excessive tilting can cause the
jack to kick out suddenly and

drop the load. See instruction 3 page 7.
5. Select the lifting point on the fork lift with care. It must be strong
enough to resist the lifting force without damaging the fork lift. It is
desirable to cradle the lifting point in the arm notch when
possible(See Fig.1-B).
6. Use only the serrated lifting
pad, or the notch at the end of
the lifting arm as the lifting
contact. Do not attempt to use
any other part of the HFJ-
700A lack as a lifting contact
point.
7. Raise a fork lift with the HFJ-700A only when:
a. The forks are in a lowered position
b. There is no load of any kind on the forks
c. There are no personnel on the jacks
8. If the fork lift truck is to be lifted, lowered and relifted, the following
procedure is to be followed.
a. Lift and lower in accordance with the instructions in this manual
b. Before using a second jack, make certain that the jack is
replaced in full accordance with the initial instructions in this
manual. (See Paragraph 4 of Operating Instructions)

SAFETY TIPS
WARNING: The warnings and
instructions listed and described
hereafter must be followed at all
times. If there is any uncertainty
regarding an intended use of the
HFJ-700A, contact your
supervisor. Failure to observe these warnings and instructions may
result in injury and/or property damage.
1. Both the HFJ-700A jack and the fork lift must be on a firm lever
surface capable of supporting the load. Do not attempt to lift from a
polished or greasy floor.
2. The HFJ-700A may be used to lift from either side or end of the fork
lift truck. However, 2 wheels of the lift truck must remain firmly on the
floor.
3. Use extreme caution when lifting narrow fork lift trucks (less than
1016mm Wide) from the sides. Always make sure that the height
between the floor and the bottom of the raised tyre is never more than
one fourth (1/4
th
) of the vehicle’s tread width. See Fig.6.(Tread width
is measured from centre line to centre line of the tyre treads.) If the
one forth figure is exceeded, the fork lift truck could reach the point of
instability and tip over or the angularity of the forklift truck frame could
cause the jack to kick out and drop the load.
Example: If treadwith=914.40mm,then never lift the bottom of the
vehicle tyre more than 228.60mm off the floor.

4. Never use more than one jack to lift the fork lift truck. Failure to
observe this instruction may lead to unstable conditions and could
cause failure of one of the jacks.
5. Do not use the HFJ-700A to raise all for 4 wheels of the fork lift from
the floor. Two wheels of the lift truck must remain in contact with the
floor at all times.
6. Do not push the jack under the
fork lift beyond the red line
marked on the decal on the top
of the lift arm. This will maintain
at least one inch clearance
between the body of the jack
and the fork lift in its raise
position. Failure to observe
these instructions could result in
damage to the HFJ-700A and/or
loss of load.
7. Do not use any kind of “cribbing”
under the HFJ-700A, or on top
of the lift pad area. The jack
must always remain in direct
contact with the floor, and the
lifting pad or notch must be in
direct contact with the fork lift.

8. Keep hands, feet and all other body parts out of the area of the
scissors mechanism at all times. This instruction applies to handling
and carrying as well as lifting and lowering the jack. The scissors
action of the lifting mechanism can cause serious injury.
9. Do not drop, throw, drive over or otherwise abuse the HFJ-700A. The
jack must be treated with the same care as any other precision tool
upon which your safety and the safety of your co-workers depends.
10.Do not drive the lift truck off the jack or attempt to move the fork lift
at any time when it is supported by the HFJ-700A.
11.Do not work on the fork lift, or
get under it for any reason until
it is properly supported by
means of adequate stands.
When the stands are in place
and are supporting the fork lift
truck, remove the HFJ-700A
from the working area before
beginning work.Fig.9
12.The HFJ-700A jack is designed solely for the lifting of fork lift trucks.
Use of the jack for any other purpose constitutes misuse of the jack.
Users of the jack hereby warned of this misuse, which can result in
physical injury and/or property damage.
13.Damaged jacks-Any jack which appears to be damaged in any way,
is found to be badly worn, or operates abnormally MUST BE
REMOVED FROM SERVICE until necessary repairs are made.
14.Do not modify the HFJ-700A jack in any manner.
15.Do not exceed the rated capacity of the HFJ-700A,which is 7000kg.

MAINTENANCE
INSTRUCTIONS:
1. Apply several drops of a grade machine oil to the stem of the pump
plunger.
2. Oil the handle joints while operating the pump handle to work the oil
in.
3. Although the hydraulic unit on the HFJ-700A is a sealed unit and will
probably never need fluid adding to the reservoir, the following
instructions shall be followed in the event fluid is needed:
To refill the reservoir, place the jack in normal upright position, and
completely lower jack by opening release knob. Carefully clean dirt
and contaminants form around the fill plug and the remove the plug.
Add Mobile DTE#13 hydraulic oil to reservoir until fluid runs out the fill
plug hole. Do not use brake fluid. (Extreme care should be taken to fill
plug the fluid contaminant free and keep dirt and contaminants out of
the reservoir of the jack.) Reinstall fill plug.
PUMP PRIMING
INSTRUCTIONS:
To prime the model HFJ-700A actuator, in the event that it
inadvertently becomes unprimed, proceed as follows:
1. Open release valve (large red knob on top) approximately 2 full tuns.
2. Stroke handle through 2 full turns, slowly.
3. Raise handle fully up, turnover jack on left side, as viewed from rear.
Push handle “down”.
4. Stand jack upright again, raise handle to up, lay over on left side
and push handle “down” again.
5. Stand jack upright, stroke handle while closing release valve and
jack should operate satisfactorily.
