TR40 OPERATOR’S MANUAL
Operation
Starting and Stopping Saw
Starting
•
This machine has a lock-off type switch.
First press the trigger release, then squeeze
the trigger switch to switch on. For safety
reasons, the switch is not possible to lock
on.
Stopping
• Release the trigger switch to stop the
machine. After the machine has been
switched off, the chain will still rotate for a
few seconds, take care that parts of your
body do not come into contact with the chain
while it is still rotating!
WARNING: Do not set the machine down until
the chain has stopped turning.
Electrical Connection
•
Connect the TR40 via the frequency
converter FU6U and via the adapter cable
only on a properly earthed shockproof
socket. If required use only high-quality
extension cords with sufficient cross
section.
•
For 230V Up to 100m length - 3G2,5 quality,
e.g. H 07BQ-F or H 07RN-F
•
For 480V Up to 100m length - 4G2,5 quality,
e.g. H 07BQ-F or H 07RN-F
•
Take care that the extension cord is not
rolled up on use for reaching a sufficient
heat removal. Consider that the TR40 takes
the maximal power from the electrical
mains.
•
If you change the operation mode of the ring
saw TR40 between 230V~ und 480v~3P the
frequency converter FU6U has to be
disconnected for approx. 2 minutes in order
to discharge the intermediate circuit and re-
initialize the controller.
TR40 and FU6 can be used at a generator or
a transformer provided by the construction
site, if following conditions are kept:
-
operating voltage 5% and –
10 % to nominal voltage
- integrated automatic voltage
controller with start amplification
- frequency 50 – 60Hz; max. 65 Hz
- AC voltage, power output at least:
230V ~ - 4 kVA
480V 3~ - 11 kVA
Cutting Technique
• Care for safe standing and keep the
balance anytime. Always hold the machine
in a firm grip with both hands.
•
When sawing, always stand parallel to the
saw blade. Do never stand directly behind
the saw blade as the saw will move in the
plane of the blade in case of a kickback.
Never use the kickback area of the ring
saw for cutting.
•
Never cut above shoulder height.
•
Do not use the ring saw from a ladder. Use
a scaffolding if you are cutting above the
shoulder height.
• Check that the saw blade is not in contact
with anything when the machine is started.
•
Avoid blockage of the saw blade by
excessive pressure, lateral stress and
excessively deep cuts. Let the machine
work without excessive force. Lateral
loading of the bar and the diamond chain
can lead to material and personal injury.
• Support the work piece in such a way that
no unpredictable movement is possible,
and so that the cut remains open while
cutting.
• When cutting openings, first perform the
lower horizontal cut, then the two vertical
cuts. Finish with the upper horizontal cut.
If the upper horizontal cut is carried out
before the lower one, the cut-out unit falls
onto the cutting equipment and jams or
damages it.
• Arrange the splash guard in such a way
that the splashes and sparks entrained by
the workpiece are caught and guided
away by the user.
