3. OPERATION DESCRIPTION

3.1 Installation

Compressed Air Connection

The compressed air should be connected to the tool preferably by a quick coupling.

It is very important to clean the compressed air with an air unit consisting of a

separator for water and dirt, a pressure regulator with a manometer and a lubricator

(see sketch).

3.2 Suspension of Tool

It is possible to suspend the tool on a spring loaded balancer using the suspension

bracket which is supplied with the tool. The suspension bracket has been designed

in such a way, that the tool can be used for all three working positions.

Main air line min. 2”

Air line min. 1/2”

3.3 Adjustments

3.3.1 Preselecting of Strap Tension and Tensioning Speed

Do not adjust the tensioning force too high.

If the tensioning force is higher than the tensioning strength of the strap, the strap

will tear while tensioning.

Tensioning force and tensioning speed can be preselected at the control head.

Loose lock screw;

Press the control head against the tool and turn it.

Turning clockwise increases; turning counterclockwise decreases the tensioning

force and the tensioning speed resp..

Tight lock screw

3.3.2 Adjusting the Welding Time

Depending on the size and quality of the strap, different welding times are required.

The welding time can be set at the adjusting screw.

Turning clockwise increases the welding time.

Turning counterclockwise decreases the welding time.

3.4 Feeding the Strap Around the Package

The strapping is fed around the package as

illustrated.

Warning! The plastic strap which will be welded

must be free from oil, grease and other dirt.

Dirty plastic straps can’t be welded correct.

3.5 Inserting the Lower Strap

Lift and hold the handle lever with the right

hand. The left hand inserts the free end of the

strap.

First between welding gripper and the welding

stop gripper and then under the stop gripper

until it hits the strap stop.

Make sure that the strap is well aligned to both

strap stops!

With the thumb move the seesaw lever up. The

strap is locked.

Do not release the handle lever.

3.6 Inserting the Upper Strap

The left hand inserts the upper strap under the

welding gripper, over the stop gripper and

between tensioning wheel and sliding jaw until it

hits the strap stop.

Pull on the strap until the strap sling touches the

package.

Release the handle lever

The strap guides close and the tensioning wheel

will move down to the strap.

3.7 Tensioning the Strap

Press down the tensioner valve lever and then

release it again after the desired strap tension

has been reached.

The tensioning operation can be interrupted and

restarted at any time.

3.8 Sealing the Straps

Press down and release immediately the

sealing valve lever.

The plastic strap is welded and cut off from the

rest of the strap.

After welding of the strapping it is neither

permitted to tension again nor to weld

again. After welding and cooling the tool

has to be removed from the strapping

before a new strapping cycle is started.

Disregard of this instruction can cause

severe malfunction and damage to the tool.

After the expiration of the adjusted sealing time, the seal has to cool down approx.

2 sec.

During that time the tool cannot be removed from the sealed strap.

After the expiration of the adjusted cooling time the welding jaw move upwards.

Now the tool can be removed from the strap.

The tool must not be removed from the strap as long as the cooling time is not

finished. Disregard of this regulation is causing insufficient seal efficiencies,

which can cause severe injuries.

3.9 Removing the Tool

Pull up the handle lever,

Pull the tool right and off the

strapping.

P380 Pneumatic Strapping Tool Operation Manual | FPA001 | Apr 2018 | Page 8

3.10 Seal –Control

A regular control of the seal is necessary. The seal can be examined visually. Make

a seal, peel it apart and examine it as follows:

Correct Seal

The seal must be completely welded over the whole

width of the strap on a length of ca. 19mm. Minor

quantities of fused plastic may overflow on sides.

Welding Time Too Short

The plastic strap is not welded over the whole width of

the strap. The seal efficiency is insufficient.

Warning! Straps with insufficient seal strength must be

removed from the package. Adjust the welding time

(see 3.3.2).

Welding Time is Too Long

If the welding time is too long the straps are

overheated. The fused plastic overflows on both sides

of the straps. The seal efficiency is affected.

Warning! Straps with insufficient seal strength must be

removed from the package. Adjust the welding time

(see 3.3.2).

3.11 Cleaning

Clean tension and sealing parts from strap abrasion

regularly using compressed air.

Do not use any mechanical tool for cleaning.

When cleaning the surface of the tool do not use

water or aggressive solvents.

3.12 Air Unit

Checking the air-pressure daily (never exceed

6 bar / 87psi)

Checking oil-level daily

The water separator must be emptied before it

is full (unless automatic)

The filter has to be cleaned following the

instructions of the manufacturer of the air- unit

Check the function and proper adjustment of

the lubricator daily (approximately 1-2 drops/min.)
