The Powerstapler is made of stainless steel and is executed in self-supporting construction.
Two adjustable and spring-loaded stacking platforms accommodate heat-retaining base parts or clean
porcelain plates or toughened glass. Special springs transport the inserted items towards the top at a con-
stant speed across the entire lift, ensuring that the dispensing height always remains the same.
Ergonomically shaped push handles with an integrated bumper protect against injuries to the hands and
damage to the appliance. Together with the corner bumpers fixed to the lower section they offer optimal col-
lision protectionin the direction of travel and guarantee an all-side protection against damage. Push handles
and corner bumpers are made of high-quality, impact-resistant plastic.
An on/off switch with an integrated display function is fitted to the front of the housing. The operating mode
can be easily seen from a distance because of theintegrated light. The thermostat is set ex factory.
The appliance is insulated all-around by high-quality special insulation. The insulating plates are non-
flammable, chemically neutral, damp-proof and harmless to health.
Two insulated covers made of stainless steel reliably protect inserted items from drying out, even during ex-
tended temporary storage periods. Covers reduce heat loss upwards and heating time. They are flat and
double-walled and have a holding-down device made of plastic.

The adjustments may only be carried out on appliances which are switched off, disconnected from the power
supply and cooled down (room temperature).
Before work starts, it is always necessary to check whether the Powerstapler is adjusted correctly for the
items to be used.
Control the dispensing height to prevent the staff from suffering injury or become trapped and to prevent
breakage of crockery can occur.
Basically, the appliance must be adjusted if at least one of the following parameters changes:
§Diameter
§Height
§Stack height
§Weight
5.2.1 Springs Adjustment
CAUTION Personal and property damage due to improper adjustment
When the dispensing height is exceeded, there is a risk of accident or injury
due to tipping of the inserted stacks. If the level of the stack falls below the
dispensing height, fingers may be injured if caught when removing dishes.
Adjust appropriately the dispensing height by attaching or detaching the
springs. When adjusting springs on sharp edges, pay particular attention to
the ends of the tension springs. Proceed with care.
CAUTION Risk of injury
Be careful when attaching and detaching the springs.
Pay particular attention to the ends of the tension springs when adjusting
springs on sharp edges.
Before loading the appliance, the dispensing height must be adjusted to the type of crockery used. The dis-
pensing height is adjusted by attaching or detaching tension springs. As long as the same kind of items is
always used, the dispensing height only needs to be set once.
Step 1 – Check the adjustment of the springs
§Place a stack of heat-retaining base parts on the stacking platform to test the dispensing height.
§Wait for the system to self-adjust.
If the stack drops down only a little or not at all, the dispensing height must be altered by adjusting the
springs.

Step 2 – Change the adjustment of the springs
The dispensing height is adjusted by attaching or detaching tension springs on four attachment bars. The
springs are arranged in groups of five, where one is a base spring with higher tension (1) and four are ad-
justable springs (2) with lower tension.
Figure 4 Attachment bar with tension springs (example)
If the dispensing height is too high, adjustable springs must be detached. If the dispensing height is too low,
adjustable springs must be added.
Procedure for adjusting the springs:
§Remove inserted stacks from the stacking platform (if available).
§Attach or detach adjustable springs evenly in all groups of springs.
§It is best to detach the adjustable springs. Always leave the base springs inserted, if possible. Always
detach the springs on the lower attachment bar.
As long as the same kind of items is always used, the dispensing height only needs to be set once.
NOTE Arrangement of the springs
The springs need to be in a symmetrical arrangement between the attach-
ment bars to ensure that the stacking platform is guided smoothly and steadi-
ly.
A slightly asymmetrical arrangement of springs within an attachment bar does
not pose a problem.
NOTE Spring system
Since Powerstapler are designed for a maximum load, the available spring
system of the appliances is entirely sufficient for all usual stack items.

5.2.2 Calculating the capacity for Powerstapler
The total capacity of a Powerstapler depends on the items loaded.
All leading manufacturers provide the necessary data for calculating the intermediate stack height in the fol-
lowing way:
HZ: Intermediate stack height
H1: Height of thefirst item
Hn: Height of n items
n: Number of items
The capacity per crockery stack can be calculated together with the stack height HSof the Powerstapler:
K: Items per stack
HS: Stack height of the Powerstapler
Figure 5 Intermediate stack height HZfor 11 items
Example:
H1= 1.1'' (28 mm): Height of the first item
H11= 5.5'' (140 mm): Height of 11 items
t= 11: Number of items
HS= 24.6'' (625 mm): Stack height
The capacity of one stacking platform in this example is 54 stacked items.
