The indicated weighted effective value of acceleration has been measured
against standard test procedures and can be used by way of comparison with
another device. The indicated weighted effective value of acceleration can also
be used as a preliminary evaluation of the exposure.
Attention: The indicated weighted effective value of acceleration can differ during
operation from the indicated value, dependent on the manner in which the device
is used. Dependent upon the actual conditions of use (periodic duty) it may be
necessary to establish safety precautions for the protection of the operator.
2. Preparations for Use
For use of the BTI pressing tongsfor the various pipe connection systems, the
currently valid BTI sales documents are applicable. If the system manufacturer
alters components of pipe connection systems or markets new ones, their
current application status must be enquired about at BTI (Fax +49 7940
141-9531).
2.1. Electrical connection
WARNING
Note the mains voltage! Before connecting the drive unit or the rapid charger,
check whether voltage on the rating plate matches the mains voltage. At work
sites, in damp surroundings, in the open or in the case of comparable types of
use, only operate the equipment off the mains using a 30 mA fault current
protected switch (FI breaker).
Rechargeable batteries
NOTICE
Always hold the battery upright when inserting it in the drive unit or the rapid
charger. If inserted at an angle it can cause damage to the contacts and result
in a short circuit which damages the battery.
Total discharging by undervoltage
The Li-Ion batteries may not drop below a minimum voltage because otherwise
the battery could be damaged by "total discharge". The cells of the BTI Li-Ion
battery are delivered pre-charged to approx. 40 %. Therefore the Li-Ion batteries
must be charged before use and recharged regularly. Failure to observe this
regulation of the cell manufacturer can lead to damage to the Li-Ion battery by
total discharging.
Total discharging due to storage
If a relatively low charged Li-Ion battery is stored, self discharging can lead to
total discharge damage of the battery after longer storage. Li-Ion batteries must
therefore be charged before storing and recharged every six months at the
latest and charged again before use.
NOTICE
Charge the battery before use. Recharge Li-Ion batteries regularly to avoid
their total discharge. The rechargeable battery will be damaged by total
discharge.

Only use a BTI rapid charger for charging. New Li-Ion batteries and Li-Ion
batteries which have not been used for a long time only reach full capacity after
several charges. Non-rechargeable batteries may not be charged.
Battery charging status check for all Li-Ion cordless presses
All BTI cordless presses made as of 2011-01-01 are equipped with an electronic
battery charging status check with battery charge indication by a 2-coloured
green/red LED. The LED lights green when the battery is fully or still sufficiently
charged. The LED lights red when the battery must be charged. If this condition
occurs during pressing and the pressing process is not finished, the pressing
must be completed with a fully charged Li-Ion battery. If the drive unit is not
used, the LED goes out after approx. 2 hours but comes on again when the
drive unit is switched back on.
Rapid charger Li-Ion/NiCd (Art. No. 9032947)
The left control lamp lights up and remains green when the mains plug is
plugged in. If a battery is inserted in the rapid charger, the green control lamp
flashes to indicate that the battery is charging. The green light stops flashing
and remains on to signal that the battery is fully charged. If the red control lamp
flashes, the battery is defective. If the red control lamp comes on and remains
on, this indicates that the temperature of the rapid charger and / or the battery
is outside the permissible range of 0°C to +40°C.
NOTICE
The rapid chargers are not suitable for outdoor use.
2.2. Installing (changing) the pressing tongs (1) in radial presses (Fig. 1)
Pull the mains plug or remove the battery. Only use pressing tongs with a
system-specific pressing contour matching the press fitting system for press i ng.
BTI pressing tongs have a letter on both pressing jaws to identify the pressing
contour and a number to identify the size. Consult and comply with the instruc-
tions for installation and fitting of the system's manufacturers. Never use non-
matching pressing tongs (pressing contour, size) for pressing work. The press
2
joint could be unserviceable, and both the machine and the pressing tongs
might be damaged.
The drive unit is best placed on a bench or the floor. Installing (changing) the
pressing tongs is only possible when the press rollers (5) in are fully retracted.
If necessary in the case of the BTI RP 108 AR and BTI A-RP 108 AR LI press
the reset button (13) until the press rollers (5) are fully retracted.
Open the tongs shank (2). To do so, press the locking pin (4), the tongs shank
(2) jumps out under spring loading. Insert selected pressing tongs (1). Push
home the tongs shank (2) until the locking pin (4) engages. While doing so,
press down the pressure plate (3) directly above the tongs shank. Do not start
radial presses without pressing tongs inserted. Do not start the pressing
operation except to make a press joint. Unless counter pressure is applied by
the press fitting, the drive unit or pressing tongs will be needlessly stressed.
CAUTION
Never operate press when the tongs shank (2) is not locked. Risk of
fracture!
3. Operation
3.1. Radial presses (Figs. 1 to 2)
Before use, always perform a trial pressing with the drive unit and the press ing
tong inserted, with the press fitting in place. The pressing tongs must close
completely. Complete closing of the pressing jaws (10) both at their tips (Fig.
1, at "A") and at the level of the connecting link (Fig. 1, at "B") must be observed
after completion of pressing. The tightness of the connection must be checked
(country-specific regulations, standards, guidelines etc. must be followed).
Before use, always check the pressing tongs, in particular the pressing contour
(11) of both pressing jaws (10), for damage or wear. Do not use damaged or worn
pressing tongs again. Otherwise there is a risk of incorrect pressing or accidents.
If during closing of the pressing tongs a marked ridge is created on the compres-
sion sleeve, the pressing may be defective or not tight (see 5. Trouble).
For preventing damages make sure to avoid operating situations like exempla-
rily shown in Fig. 3 through 5, that no distortion between pressing tongs, pressing
tongs Mini, pressing rings, adapter tongs, fitting and drive unit occurs.
3.1.1. Working procedure
Press the pressing tongs (1) together manually until they can be pushed over
the press fitting. Always position the drive unit with the pressing t ongs on the
press fitting at right angles to the pipe axis. Release the pressing tongs so that
they close around the press fitting. Hold the drive unit by the housing grip (6)
and the pistol grip (9).
In the case of the BTI A-RP 108 AR LI and BTI RP 108 AR, hold down the
inching switch (8) until the pressing tongs are completely closed. After comple-
tion of press ing, the drive unit switches automati cally to return (forced return).
Press the pressing tongs together manually so that they can be removed from
the press fitting.
3.1.2. Operating safety
BTI A-RP 108 AR LI and BTI RP 108 AR ends the pressing operation auto-
matically, emitting an acoustic signal (clicking), and returns automatically (forced
movement).
NOTICE
Only complete closing of the pressing tongs provides a perfect press
joint. Complete closing of the pressing jaws (10) both at their tips (Fig. 1,
at "A") and at the level of the connecting link (Fig. 1, at "B") must be
observed after completion of pressing. If during closing of the pressing
tongs a marked ridge is created on the compression sleeve, the pressing
may be defective or not tight (see 5. Trouble).
3.1.3. Working safety
To ensure safe working, the drive units are equipped with a safety inching
switch. This permits immediate switching off of the drive units at any time,
particularly if a potential hazard arises. The drive units can be switched to the
return function in any position.
3.2. Battery charging status check with complete discharge protection
All BTI cordless presses made as of 2011-01-01 are equipped with an electronic
battery charging status check with battery charge indication by a 2-coloured
green/red LED. The LED lights green when the battery is fully or still sufficiently
charged. The LED lights red when the battery must be charged. If this condition
occurs during pressing and the pressing process is not finished, the pressing
must be completed with a fully charged Li-Ion battery. If the drive unit is not
used, the LED goes out after approx. 2 hours but comes on again when the
drive unit is switched back on.
4. Maintenance
WARNING
Notwithstanding the servicing listed below it is recommended to send in the
BTI drive units together with all the tools (e.g. pressing tongs) and accessories
(e.g. batteries, rapid chargers) at least once a year to an authorised BTI customer
service station for inspection and repeated inspection of electrical equipment
in accordance with EN 62638:2010-08 (VDE 0702).
4.1. Maintenance
Before maintenance work, pull the mains plug or remove the battery.
