3. Maintenance
3.1 Hydraulic oil - Check the oil level every six months. The oil must be hydraulic oil: ISO VG32, its viscosity
should be 32 CST at 100
℉
total volume is about 4.2 qts. use temperature 0
°
F - 120 F R
eplace the
hydraulic oil (every 12 months).
3.2 Daily check and maintenance - Check the 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, the chain,
the battery should be checked, too. The forks should be unloaded and lowered in the lowest
position when the job is over.
3.3 Lubrication - Use motor oil or grease to lubricate all movable parts.

.To adjust release device
On the draw-bar of this hand stacker, you can find the control handle (
①
on Page21) 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:
4
.1 If the forks elevate while pumping in the NEUTRAL position, turn the adjusting nut(
on Page21)
on the
adjusting bolt (
⑨
on Page21
)
clockwise or turn the adjusting screw (
⑨
on Page10
)
clockwise until pumping
action does not raise the forks and the NEUTRAL position functions properly.
4
.2 If the forks descend while pumping in the NEUTRAL position, turn the nut (
on Page21)
or the screw (
⑨
on
Page10
)
counter-clockwise until the forks do not lower.
4
.3 If the forks do not descent when the control handle (
①
on Page21
)
is in the LOWER position, turn the nut (
on Page21
)or the screw(
⑨
on Page10
)
clockwise until raising the control handle (
①
on Page21
)
lowers the
forks. Then check the NEUTRAL position according to item 4.1 and 4.2 to be sure the nut (
on Page21)
and
the screw (
⑨
on Page10
)
is in the proper position.
4
.4 If the forks do not elevate while pumping in the LIFT position, turn the nut (
on Page21)
or the screw(
⑨
on
Page10
)
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.

2.1 Operator should read all warning signs and instructions here and on the stacker before using it.
2.2 Do not operate a stacker unless you are familiar with it and have been trained or authorized to do so.
2.3 Do not operate a stacker unless you have checked its condition. Give special attention to the chain, wheels,
handle, guide frame, pilot wheel, mast, battery, etc.
2.4 Do not use on a slopping surface, rough, explosive or dangerous environment.
2.5 Do not lift people using the forks.
2.6 While lifting the forks, do not allow anyone to stand under or around the forks.
2.7 The operator should use safety shoes and gloves to protect against crushing or cutting hands or feet. Keep
feet out from underneath the load.
2.8 Do not move the stacker when the goods are lifted to the height more than 2 feet.
2.9 While the goods are being transported or lifted, all people should stay a minimum of 2 feet away from
stacker.
2.10 The weight of goods should be evenly 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.
2.11 Do not load beyond the maximum capacity according to the capacity diagram. Heavy loads should not be
allowed to remain on the forks for a long time after operation is over.
2.12 Before using or charging it, check the battery connection.
2.13 Charging should be in dry and ventilated location, and far away from any fire.
2.14 Keep the forks in the lowest position when not in use.
2.15 Do not use the truck when traveling on semi trailers.
2.16 Do not use the truck in a potentially explosive atmosphere.
2.17 Do not use the truck as a vehicle jack.
2.18 Do not use under windy conditions.
2.19 Do not use the truck in places insufficiently illuminated.
2.20 Do not use the truck with guarding removed.
2.21 Stacker should be parked on a smooth & level place, keep power off, lower the forks to the min. height, and
press on the brake. Stacker should not be parked in an unsafe area such as busy streets, intersections, narrow
roads, blind curves, slopes, soft ground, place that are flammable or fire fighting access.
2.22 In unknown environment, the operator should be careful while operating the pallet truck.
2.23 Unauthorized truck modification is not permitted. No modifications or alterations to a powered industrial
truck, which may affect, for example, capacity, stability or safety requirements of the truck, shall be made
without the prior written approval of the original truck manufacturer, its authorized representative, or a
successor thereof. This includes changes affecting, for example braking, steering, visibility and the addition of
removable attachments. When the manufacturer or its successor approve a modification or alteration, they shall
also make and approve appropriate changes to capacity plate, decals, tags and operation and maintenance
handbooks. Only in the event that the truck manufacturer is no longer in business and there is no successor in
the interest to the business, the user may arrange for a modification or alteration to a powered industrial truck,
provided, however, that the user shall: a) Arrange for the modification or alteration to be designed, tested and
implemented by an engineer(s) expert in industrial trucks and their safety. b) Maintain a permanent record of the
design, test(s) and implementation of the modification or alteration. c) Approve and make appropriate changes
to the capacity plate(s), decals, tags and instruction handbook. d) Affix a permanent and readily visible label to
the truck stating the manner in which the truck has been modified or altered together with the date of the
modification or alteration, and the name and address of the organization that accomplished the tasks.
