1. The correct use of electric stacker
Described in this manual of the full electric walkie straddle stacker. This
equipment is to reduce the handling and transportation of your load efficiently.
Improper use may result in personal injury or damage of the machine.
The operator must ensure proper usage and be authori ed and trained before
use. This stacker should always be on a flat surface while lifting any material.
This stacker should be used in room temperature environments. Not
recommended for operation and lifting on slopes. Loads should always be
centered within the 24” load center from backrest. It is strictly prohibited to lift
or carry personnel. Load of material must be reduced to the max lifting point
(138in).
Rated load is in the load curve on the label of the unit. The operator should pay
attention to these warnings and safety instructions.
Changing:
Load ratings affect the stability and safety of the operations of this equipment.
This includes the effects of the changes, such as: brake, steering, Increase the
visibility and mobile accessories. When the manufacturer or its successor
approved modify or change, load curve, label, the identification mark,
operation and maintenance manuals will be corresponding to the changes.
Any changes made or damaged due to misuse of this products will lose the
warranty.

5.1 Parking
Not recommended to stop on a slope.
This car is equipped with an electromagnetic fault protection parking and parking brake.
However, please always completely lower the fork at all times. Turn key counterclockwise rotation,
then remove the key.
5.2 Load Curve
Load curve shows a given load center C [mm] and hori ontal load capacity of the largest load Q [kg]
vehicle corresponding lifting height is H [mm].
The white mark on the door frame representation can reach ascension range.
For example: a cargo gravity center distance of C is 24”, the maximum lifting height H
119in, the maximum load capacity of Q to 1540lbs.
5.3 Lifting Loads
Do not overload. The maximum load capacity of this car is 1540lbs at max height.
Only increase the load capacity allowed by the load curve.
When traveling, lower the fork to 11.8in to reduce to a car on the leg, and press the lift button (Figure
1, 11) until you reach your expectations lifting height.
5.4 Lowering Loads
Always lower the loads slowly and carefully without any shifting or turning. Carefully press the
down button, then carefully pull away from the goods.
5.5 Traveling
Always travel with slower speeds with loads and when going up ramps have the load facing forward.
Travel with caution and awareness of your surroundings.
Always lower your load to a minimum when traveling.

Fig 7: Goods Up
Turn on the equipment with key, pull the emergency button switch upward if not engaged. Raise the
forks at a minimum height of at least 3-6 inches off the ground to avoid getting caught up on
anything (Figure 11)
Carefully accelerator butterfly throttle on the handle to determine if you are moving forward or
backwards. (Figure 12).
