plug. The device must never be used with an extension cable. The required power
supply depends on the country of operation – please check the type plate on the unit for
the minimum prescribed fuse value in the socket. Use socket with an earth leakage
circuit breaker!
Arrange the mains cable in such a way that it does not create a tripping hazard.
Safety equipment
The EZ50 Stringing Gun is equipped with an integrated thermal safety switch.

Applications
The EZ50 Stringing Gun is intended exclusively for blowing in or sucking out special
pull lines in pipe work that has already been laid. Then, cables or extra strong pull

and damage to the machine. Never attempt to modify your electrical tool in any way
since this may result in accidents or damage to the machine.
Disposal of lines
Used lines can also be used for other purposes or must be properly disposed of. All
relevant regulations and laws of the particular country must be complied with when
disposing of old lines. Lines that have already been used must not be used again in the
cylinder for pull line of the Stringing Gun.
Personal protective equipment

Clothing must be sturdy but allow complete freedom of movement. Wear
snug-fitting clothing, an overall and jacket combination, do not wear a work
coat.

5. Putting into Operation
1. Before any unit is put into operation, firstly ensure that the device is in
perfect and clean condition and the front plate is clicked on correctly.
2. Do not work in the vicinity of flammable or explosive materials, fluids, gases or
open flames
3. In the event of any faults or the suspicion of a fault, disconnect the mains plug
immediately and have the device checked over by the importer or the
manufacturer

6. First blow through the conduit without any line (to clear any water, impurities or
the like in the conduit)
7. Use protective eyewear (beware of dust, water etc.)
8. If any residual water is actually left in the ducting, never work in suction mode
(damage to the motor)
9. Always keep the air intake opening/screen free (danger of overheating/fire). If
any impurities are found in the screen, remove them immediately
10. Never use the device if the mains cable is damaged. Have faulty cables or
plugs replaced immediately (by the manufacturer or the importer). Never pull
the plug out of the mains socket by the cable if your hands are wet. Do not drag
the cable across sharp edges or corners. Never place the cable on hot objects.
11. Caution: some of the plastic parts have limited impact resistance!
Warning!
Improper application, use, modification, operation or maintenance
can lead to serious personal injury or damage to property!
To reduce the risk of personal injury from fire, never attempt to
suck on hot or burning substances (e.g. smoldering ashes, glowing
cigarettes).
To reduce the risk of fatal injury from fire or explosion, never attempt
to suck on combustible fluids (e.g. gasoline) or materials soaked in
combustible fluids.
