Welcome to use our hand stacker FS series. Your stacker
is made of high quality steel and was designed to give a
durable, reliable and easy to use product. For your safety and
correct operation, please carefully read this instruction book
and warnings on the stacker before using it.
Note!
All of the information reported herein is based on data
available at the moment of printing. The factory reserves the

2. InSTALLATIOn & ADjUSTMenT
*To prevent oil-leaking from oil tank during transportation. Air Screw(part
No.FS236) is replaced with oil-sealing screw in the factory but it has to be
replaced back when you put this stacker in use.
*How to change: screw out oil-sealing Screw, then screw in Air Screw which is in
the spare parts bag, thus keep oil tank always connecting with atmosphere.
3. SAFeTY GUIDAnCe
3.1 Operator should read all warning signs and instructions here and on the
stacker before using it.
3.2
Do not operate a hand stacker unless you are familiar with it and have
been trained or authorized to
do so.
3.3 Do not operate a hand stacker unless you have checked its condition.
Give special attention to the wheels, the
handle, the guide frame, the pilot wheel, the doorframe, etc.
3.4 Do not use on a slopping ground.
3.5 Do not take up any people on the forks.
3.6 The operator had better take on gloves for labor protecting.
3.7 When the goods have been transported or lifted, all people should be
away form the forks for 600mm.
3.8 Do not load over maximum capacity.
3.9 The weight of goods should be distributed on the two forks, do not use
only one fork. The center of gravity of goods should be in the center of two
forks.
3.10
People forbid standing under the forks.
3.11 Do not move the hand stacker when the goods are lifted to the height
more than 300mm.
3.12 At other special condition or place, the operator should be carefully to
operate the hand stacker.
4. MAInTenAnCe
4.1 Hydraulic oil
Please check the oil level every six months. The oil can be hydraulic oil: ISO
VG32, its viscosity should be 32cSt at 40oC, total volume is about 2.0lt.
4.2 Daily check and maintenance
It is necessary to check the hand stacker daily. Special attention should be
paid to the wheels, the axles, as thread, rags, etc., it may block the wheels, the
fork and the mast should be checked, too. The forks should be unloaded and
lowered in the lowest position when the job is over.
4.3 Lubrication
Use motor oil or grease to lubricate all movable parts.
4.4 Remove the air
The air maybe enter the hydraulic pump during the transportation after the
customer buys it. It will cause the piston rod to fail to keep up the raised height.
The air can be removed in the following way: pull the control handle(FS107) up
and move handle(FS110) up and down for several times.
5. TO ADjUST ReLeASe DeVICe
On the draw-bar of this hand stacker, you can find the control handle (FS107)
which can be regulated in three positions: LOWER = to lower the forks;
NEUTRAL = to move the load, and LIFT = to raise the fork. These three positions
have been pre-posited at the factory. If however they have been changed, you
can adjust according to following step:
5.1 If the forks elevate while pumping in the NEUTRAL position, turn the
adjusting nut (FS116) on the adjusting bolt (FS115) clockwise or turn the
adjusting screw (FS223) clockwise until pumping action does not raise the
forks and the NEUTRAL position functions properly.
5.2 If the forks descend while pumping in the NEUTRAL position, turn the nut
(FS116) or the screw (FS223) counter-clockwise until the forks do not lower.
5.3
If the forks do not descent when the control handle (FS107) is in the
LOWER position, turn the nut (FS116) or the screw (FS223) clockwise
until raising the control handle (FS107) lowers the forks. Then check
the NEUTRAL position according to item 5.1 and 5.2 to be sure the
nut (FS116) and the screw (FS223) is in the proper position.
5.4
If the forks do not elevate while pumping in the LIFT position, turn the nut
(FS116) or the screw (FS223) counter-clockwise until the forks elevate while
pumping in the LIFT position. Then check the LOWER and NEUTRAL
position according to item 5.1, 5.2 and 5.3.
6. TROUBLeS SHOOTInG
Trouble Clause Fixing Methods
The forks can not be up
the max. height.
- The hydraulic oil is not
enough.
- Pour in the oil.
The forks can not be
lifted up.
- Without hydraulic oil.
- The oil has impurities.
- The nut (FS116) is
too high or the screw
(FS223) is too close,
keep the pumping valve
open.
- Air come into the
hydraulic oil.
- Fill in the oil.
- Change the oil.
- Adjust the nut
(FS116) or the screw
(FS223) .(see item
5.4)
- Banish the air (see
item 4.4)
The forks can not be
descended.
- The piston rod(FS250)
or pump body(FS257)
or the mast (FS301 or
FS301G) is deformed
resulting from loading
slanting to one side or
over-loading.
- The fork was kept in the
high position for long
time with piston rod
bared to arise in rusting
and jamming of the rod.
- The adjusting nut
(FS116) or the screw
(FS223) is not in the
correct position.
- The rollers (FS339) are
not lubricated.
- Replace it.
- Keeping the fork in
the lowest position if
not using, and pay
more attention to
lubricate the rod.
- Adjust the nut(FS116)
or the screw (FS223).
(see item 5.3)
- Lubricate its.
Leaks
- Sealing parts worn or
damaged.
- Some part cracked or
worn into small.
- Replace with the new
one.
- Replace with the new
one.
The fork descends
without the release
valve worked.
- The impurities in the oil
cause the release valve
to be unable to close
tight.
- Some parts of hydraulic
system is cracked or
bored.
- Air come into the oil.
- Sealing parts worn or
damaged.
- The adjusting nut
(FS116) or the screw
(FS223) is not in the
correct position.
