Lincoln Electric IM608 X-TRACTOR 4G - Manual (Page 12)

C-1 MAINTENANCE C-1
Before any service or maintenance work is carried
out, the following safety precautions must be
observed.
- Main power supply must be switched off and locked
in the “OFF” position. A warning sign must be put on
the switch to be sure that no one enters the start
cabinet or tries to switch on the power supply.
- Always follow the warning stickers on the unit.
- Do not remove any protective guards before all mov-
ing parts have stopped.
- All service and maintenance must be done by quali-
fied individuals.
- Always use spare parts as described in the Spare
Part List or Lincoln Electric Brown Parts Book.

ROUTINE MAINTENANCE
Since the X-Tractor 4G is a three-phase, brushless
system with automatic filter cleaning, maintenance is
minimal. Periodic disposal of the particulate should
be the only routine maintenance. The motor and
blower bearings are permanently lubricated.
EMPTYING THE PARTICULATE BIN
The particulate matter collected in the canister may be
dangerous to your health. Take necessary precau-
tions so that you and your fellow workers do not
breathe the dust and particulate. Wear a suitable res-
pirator when disposing of the particulate.
------------------------------------------------------------------------
Check with local authorities for regulations governing
the disposal of this material.
REPLACING THE FILTER
The filter is a long life, polyester filter designed to be
repeatedly cleaned by the X-Tractor’s automatic jet
pulse cycle. Therefore, it should need replacement
only after an extended period of time. Certain applica-
tions can reduce this period, especially those involving
very oily smoke or excessive moisture. Replacement
is necessary when, after several cleaning cycles, the
suction performance of the system is still lower than
normal. Overall filter life depends on a great number
of variables such as type of smoke, duty cycle, operat-
ing factor, capture efficiency, etc.
When replacing the filter, fold down the rubber seals
that seal the canister to the unit. Slide the canister out
of the cabinet. Unlock the canister clamp and lift the
lid. Unscrew the nut under the filter, remove the filter,
install a new filter and replace the nut. Replace the lid
on the canister and clamp down.
The canister should be emptied on a regular basis.
Frequency of emptying depends upon a number of
factors such as the type of welding fume and the fre-
quency of use. In many cases, a good procedure
would be to empty the canister once per month.
TIMER FOR FILTER CLEANING
(See Figure C.1 for timer illustration) The Cleaning
cycle is controlled by the adjustable timer. Cleaning
frequency can be adjusted by setting the Pause Time
(time between pulses). Pause Time is adjustable from
0.2 to 45 minutes. Pulse Duration can also be adjust-
ed from 0.1 to 30 seconds. The timer is factory preset
at 2 seconds Pulse Duration and 45 minutes Pause
Time. Thus every 45 minutes, the system pulses air
into the filter for 2 seconds.
The system can be manually triggered by pressing the
“Test” button. The green LED is lit when the timer
senses power to its control circuit; the Yellow LED
lights when the timer signals a pulse.
