For working in alternating positions a turnable suspension bracket with screws and washers can be ordered
under item number P32.0223.
1.1.6 Fan
In order to avoid overheating of the motor we recommend at environmental temperatures above 40°C / 104°F
using the optional fan P32.0228.
(see 1.4.7 Assembly information)
1.2 TECHNICAL DETAILS
1.2.1 Strap tension
The tension force values mentioned in the operation manual (250-2600N) are not achievable with each strap.
They depend on following factors:
•Hardness of the package,
the maximum tension force values are achievable with hard packages.
•Elongation and creep properties of the plastic strap,
the maximum tension force values are achievable by using plastic straps with a low elongation.
•Surface quality of the plastic strap,
the maximum tension force values are achievable with waxed and embossed straps.
•Strap width, strap thickness,
the maximum tension force values are achievable with thick and wide straps.

1.4 PERIODIC MAINTENANCE AND CONTROL
(Carry out 12- months cycles doing one shift work. Doing more shift work respectively more often.)
To a v o i d d a m ages o n t h e mo t o r sha ft the t wo n e edle free wheelings N3.4509 and N3.4520 have to be
replaced after 80 000 strapping cycles.
1.4.1 Procedure
Before using check tool for following possible faults:
•Visual test of the tool for loose, lost or damaged parts
•Clean all dirty parts of the tool, especially strap abrasion in the tensioning or the welding unit by
using compressed air. (Never use any hard tools like a wire brush or a screw driver for cleaning)
Carry out a test strapping and check following:
•Insertion of the strap
•Strap feed and strap tensioning
•Tensioning force adjustment (see operation manual P328)
•Cutting of the upper strap
•Welding time adjustment (see operation manual P328)
• Seal quality (see operation manual P328)
•Function of the LED - display
Proceed according to paragraph 1.4.2 after a fault appears.
For exchange of wearing parts see operation manual P328.
Attention!
Remove battery from tool before each maintenance work.
Never use water or solvents for cleaning the tool’s surface.
