Specific Safety Instructions; Preparations For Use - Roller Pulsar Instructions D'emploi

eng
c) Disconnect the plug from the power source before making any adjust -
ments, changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to ope-
rate the power tool. Power tools are dangerous in the hands of untrained
users.
e) Maintain power tools. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the
power tools operation. If damaged, have the power tool repaired by
a qualified expert or by an authorised ROLLER after-sales service
facility before use. Many accidents are caused by poorly maintained po-
wer tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools
with sharp cutting edges are less likely to bind and are easier to control.
g) Secure the workpiece. Use clamps or a vice to hold the workpiece. This
is safer than holding it with your hand, and also it frees both hands to ope-
rate the equipment.
h) Use the power tool, accessories and tool bits etc., in accordance
with these instructions and in the manner intended for the particu-
lar type of power tool, taking into account the working conditions
and the work to be performed. Use of the power tool for operations diffe -
rent from those intended could result in a hazardous situation. All unaut-
horised modifica tions to the power tool are prohibited for safety reasons.
E) Battery tool use and care
a) Ensure the switch is in the off position before inserting battery pack.
Inserting the battery pack into power tools that have the switch on invites
accidents.
b) Recharge only with the charger specified by the manufacturer. A
charger that is suitable for one type of battery may create a risk of fire
when used with another battery pack.
c) Use battery tools only with specifically designated battery packs.
Use of any other battery packs may create a risk of injury and fire.
d) When battery pack is not in use, keep it away from other metal objects
like paper clips, coins, keys, nails, screws, or other small metal
objects that can make a connection from one terminal to another.
Shorting the battery terminals may cause bums or a fire.
e) Under abusive conditions, liquid may be ejected from the battery,
avoid contact. If contact accidentally occurs, flush with water. If li-
quid contacts eyes, additionally seek medical help. Liquid ejected
from the battery may cause irritation or bums.
f) Do not use the battery/charger at battery/charger temperatures or
ambient temperatures of 5°C/40°F or 40°C/105°F.
g) Do not dispose defective batteries in the normal domestic waste.
Take them to an authorised ROLLER after-sales service facility or to
a reputed waste disposal company.
F) Service
a) Have your power tool serviced by a qualified repair person using on-
ly identical replacement parts. This will ensure that the safety of the po-
wer tool is maintained.
b) Comply with maintenance instructions and instructions on tool re -
place ments.
c) Check mains lead of power tool regularly and have it replaced by a
qualified expert or an authorised ROLLER after-sales service facili-
ty in case of damage. Check extension cable regularly and replace
it when damaged.

Specific Safety Instructions

• The electrodes reach a working temperature of around 900°C – so never
touch either the electrodes or the front of the tongs or the work piece,
whether during or alter soldering!
• When putting down the tongs after soldering, ensure that the front part of
the tongs, which is still hot, is kept away from inflammable materials.
•
Change worn electrodes and electrode holders.

2. Preparations for Use

2.1. Electrical connection:
The soldering unit must be connected to a socket with a protective earth
(earthed wire). Ensure that the mains voltage is correct! Before connec-
ting the unit, check that the mains voltage is the same as that specified
on the rating plate.
2.2. Selecting the electrodes:
As a rule, the prisma electrodes (Fig. 1 [1]), are used, since they have
a larger area of contact with the pipe and hence heat up the latter faster
than the rod electrodes (2). The rod electrodes are intended for cram-
ped spots where operation with the prisma electrodes is not possible.
3. Operation
3.1. Mode of operation:
Once the electrodes of the soldering unit are applied to a metallic con -
ductor, e. g. a copper pipe, a circuit with low voltage and high current
intensity is closed by pressing the switch (3). The electrodes have a re-
latively high resistance in the transformer/cable/electrodes/work piece
circuit, and therefore heat up. They may become red hot with larger pipe
sizes. The resultant heat is transmitted to the workpiece by heat con-
duction, and the workpiece is heated to soldering tempera ture in a mat-
ter of seconds.
3.2. Operating sequence:
Prepare the soldering joint properly (see also 3.3). Connect the unit to
a protectively earthed socket. Attach the tongs (Fig. 1 [4]) with the pris-
ma electrodes (1) or – in narrow spots – with the rod electrodes (2) to
the workpiece. Operate the switch (3). Keep the switch (3) pressed during
the soldering operation. The soldering temperature is reached within
seconds. Feed in the solder until the soldering gap is filled. Release the
switch (3). Remove the tongs from the workpiece. lf the workpiece is not
precisely fixed, it can be held in the tongs while the switch (3) is open
until the solder has soli dified.
3.3. Soldering material:
Use ROLLER'S Lot Cu 3 for soft-soldering. Copper pipes and fittings
must have a bright metal surface. To prepare the soldering joint, spread
ROLLER'S Paste Cu 3 over the pipe. This paste contains soldering pow -
der and flux. The advantage of the paste is that its change in colour in-
dicates that the temperature needed for soldering has been reached,
and that a better filling of the soldering gap is achieved. In any event,
however, ROLLER'S Lot Cu 3 must be added too. ROLLER'S Lot Cu 3
and ROLLER'S Paste Cu 3 have been designed specially for drinking
water pipes, and they comply both with German regulations as set forth
in DVGW work sheets GW2 and GW7, and with DIN standards. ROL-
LER'S Paste Cu 3 has been tested and approved by DVGW (DVGW Fl
038 test symbol).
