Falling parts
General areas of application of the PKL are for knocking off adhesive bulk
materials from container walls (e.g. silos, hoppers, filter outlets, pipelines
and reactors) and for emptying residues from weighing containers. The
PKL also prevent bridging and rat-holing, so that the material can continuously flow.
The PKL can be used outdoors and in dusty environments, however not in
water or any other liquids.
PKL may only be operated with a timed on/off sequence.
Any other use is considered improper.

The noise level of the PKL may exceed 80 dB(A) (single noise incident).
Depending on the impact sequence the continuous noise level is below
this value.
The PKL should be preferably mounted with the EE kit. The noise reduction is about ca. 5 dB(A) (single noise incident).
The sound em itted by the PKL can be dampened by hoods (on request).
This is only worthwhile if the impacted sheet metal is also insulated (e.g.
by heat insulation material).

p Compressed air
F Impact force
The PKL is a pneumatic „hammer“. Compressed air (p) goes under the
piston (4) and presses it against one or two springs (3).
When exhausting, the air chamber beneath the piston empties abruptly via
the quick air-exhaust valve (1).
The piston (4) (hammer) is struck by the spring force against an impact
plate (6), which then passes the impact force (F) on. For PKL without an
impact plate (PKL 190, PKL 450 and PKL 740), the piston strikes directly
against the fastening surface. The impact plate in the standard types (PKL
2100, PKL 5000 and PKL 10000) is always made of steel and can also be
replaced by an elastomer impact plate, if necessary.
The air escapes via the silencer (2).
The PKL only work when mounted, as the piston chamber is then sealed
by a built-in O-ring in the mounting surface.
A quick-air exhaust valve and a 3/2-way valve are integrated in the valve
head of the PKL 740. Therefore, the control valve on the customer's site
can be mounted at any distance away from the PKL 740.
The control air must be connected at the side. A silencer is mounted on
the exhaust air outlet.
The ST kit allows a continuous impact sequence with permanent compressed air supply.
The EE kit reduces the noise level and generates a rubber hammer effect.

Special transport conditions are not required.
When moving the PKL 10000, use the mounted transport lugs at the top of
the housing.
The PKL are packed and ready for assembly. Accessories and add-on
parts are delivered unmounted, unless otherwise agreed upon.
The packaging protects the PKL from transport damage. The packaging
material has been selected from an environmentally safe and technically
disposable point of view and is therefore recyclable.
The return of packaging to the material cycle conserves raw materials and
reduces the amount of was te.
Storage
The PKL 2100, PKL 5000 and PKL 10000 are delivered with a transport
safety device at the bottom. The transport safety device consists of 2 plastic fastenings and a corrugated cardboard disc. It prevents the impact plate
from falling out during transport and must be removed before installation.
Take care that the impact plate and damper plate retain their position on
the PKL, as they must be mounted with the PKL.
• Store the PKL in a dry and clean environment.
• The storage temperature is between -20 °C and +60 °C.
• Close all openings when re-storing.
• Preserve the PKL befor e storag e:
1. Screw or clamp the PKL on a plate. The impact plate of the PKL
2100, PKL 5000 and PKL 10000 must be inserted.
2. Apply anti-corrosion oil to the air inlet and briefly activate the PKL.

The ST kit connects the control port to the piston chamber. The PKL
equipped with the ST kit strikes as long as there is compressed air.
• For PKL 190 / 450 proceed as follow s :
- Mount the ST screw fitting (after the NBS).
- A 3/2-way valve with air supply is necessary.
• For PKL 740 proceed as follows:
- Replace the silencer with the compressed air connection.
- Only one air supply is necessary.
• Order the PKL 2100 directly with the ST control.
• For PKL 5000 proceed as follow s:
- Mount the control valve of the ST control to the PKL.
- The control valve is connected internally to the piston chamber, the
ST control is integrated in the PKL.
For detailed information, please refer to the Assembly Instructions for the
ST kit.
For all installations, use a ball valve to shut off the main line and a maintenance unit.
The maintenance unit should comprise a filter, a regulator and a mist lubricator (see Ch. Technical data, page 7; "Drive medium").
Connect the PKL with the pneumatic hose according to the following depicted pneumatic circuit diagrams.
Define the impact sequence of the PKL with an electrical control, e.g. the
Netter Electronic Timer AP 117. Electrical or pneumatic controls are available on request.
Recommended cross-sections for control lines, control valves and main air
supply: NW 6 × 1
To connect the control valve to the PKL:
• NW 6 should be used and
• a length of 15 m should not be exceeded.
For simultaneous oper ati on o f sev er al PKL
• larger cross-sections are to be provided for the main line up to distribution to the individual PKL.
• the total length of the compressed air supplies is max. 50 m.

start-up
Please refer to Ch. Technical data, page 7 for permissible operating conditions.
When selecting the mist lubricator, take into consideration that the air consumption of the PKL is very low. The choice of mist lubricator depends on
how many PKL are oper ated simul t an eous l y .
Mist lubricators with 1/8”- and 1/4”-connections are recommended. Larger
mist lubricators may not react.
Set the mist lubricator to the smallest safely adjustable number of drops
while the PKL is running. The PKL is ready for operation only after adjustment and correct functioning of the mist lubricator.
PKL with ST control: impact frequency can be set by the non-return throttle
valve.
PKL without ST control: regulation of impact frequency is set by an external control, e.g. a 3/2-way valve and a Netter Electronic Timer (AP).
The impact force can be reduced by lowering the pressure (exception PKL
with ST kit). Throttling the air supply (by using a non-return throttle valve,
shut-off valve, etc.) does not reduce the impact force but delays the charging time.
Check that the following steps have been carried out:
Hose connections checked before installation?
For installation without ST kit:
Desired impact force set on pressure regulator?
For installation with ST kit and impact frequency control with a
non-return throttle valve:
Impact frequency set optimally?
Note that a high impact frequency reduces the service life and
leads to a high sound level.
Mist lubricator set, if applicable?
After one hour of operation:
Hose supply connections, fastening and locking screws checked
and tightened, if neces sar y?
Observe the maintenance plan.

Maintenance of the PKL must be carried out as follows:
Interval Action
Cleaning
Maintenance
intervals
Implementation by Netter
After one hour of operation after initial commissioning
Check fastening and locking screws.
Check hose screw connections and hose connections and
retighten, if necessary.
Monthly Check fastening and locking screws.
Check hose screw connections and hose connections and
retighten, if necessary.
Check hose supply connections for permeability and kinks. If
necessary, clean and remove kinks.
Check the function of the silencer.
Check impact effect.
Ensure that mist lubricator operates according to regulations
(content decreases? number of drops/h? Refill oil.
Empty the filter of the maintenance unit if necessary, clean
the filter insert (wash out) and replace if necessary.
At the latest after a total
of 500,000 strokes
Carry out the general overhaul, in which all wear parts must
be replaced.
In the course of its service life, a film can form due to wear, which impairs
functioning. If loss in performance or standstill is noticed, proceed as follows:
1. Remove piston.
2. Clean piston.
3. Replace guide ring and piston seal, if necessary.
4. Reinsert piston.
Special tools are needed for inserting piston, guide rings and piston seal
(available on request).
The maintenance intervals depend essentially on the service life, how
clean the drive medium is and the lubricant used. Unfiltered compressed
air leads to high wear, blockage of the silencer and complete breakdown
of the PKL.
Maintenance, repair and general overhaul of the PKL may alternatively be
performed by NetterVibration.
