5.1 Precautions

Even though the magnetism works through non-
magnetic bodies such as dusty air and non-ferrous
materials in general the best efficiency of any magnetic
hoister is achieved when the poles (*) make good
contact with the load.
The annexed force curve (performance sheet) shows
the drop of clamping force F (kgf) of the hoister with
increase in the air gap "T" (in mm.), generated by
anything improper such as spaces between poles and
the load such as calamine, foreign bodies, low places,
protuberances, strapping, etc.
A) It is recommended to avoid as much as possible
setting down the hoister in places on the load that are
very dirty or deformed. If this happens, observe the
performance instructions of the force/air-space curve
for the load characteristics. This curve is shown on the
hoister and in the annex of the manual with perform-
ance sheet.
B) It is recommended to clean the surfaces of the load
and the poles before putting down the lifting device. If
this happens, observe the performance instructions of
the force/air space curve for the load characteristics.
This curve is shown on the hoister and in the enclosure
of the manual – performance sheet
C) It is recommended to occasionally check the
mechanical condition of the magnetic poles to make
sure they are flat and not damaged by mechanical
accidents during its time in use.
(*) "Poles" means only the areas or surfaces of the
hoister which make contact with the load.

5.2 Start up instructions

After opening the lifter packing, installation and start-up
are very simple and safe provided load limits of the
lifter, crane and hook on which the lifter is suspended
and the applicable standards are observed for handling
suspended loads. (See note, on the next page).
A) Remove lifter from packing and set on an iron plate
(Fig. 1). This operation is to be done with a crane by
hooking the lifter to the bracket.
B) Remove both the lifter's "handle" (with the threaded
end) and the "fixing lever" from the packaging. (Fig. 1).
Models HIT 125, 250, 500, HIT DB 150 and 300 are
delivered with the control lever installed, so the tool
required to install it is not supplied.
C) Insert the "fixing lever" and rotate the central hub so
that the "threaded hole" is visible. (Fig. 2).
D) Insert the lever in the threaded hole and firmly lock it
(Fig. 3).

E) Insert the threaded end of the handle and screw it
into position ensuring that the handle is tight (Fig. 4).
F) Place the lifter on the load to be handled. Carefully
check that the load fits with the prescribed capacity
range of the lifter (see nameplate or enclosed
performance sheet). Also check that the magnetic poles
of the lifter are perfectly and totally in contact with the
load to be handled. If said load is round or tubular,
make sure it is well centered between poles.
It is necessary for the operator to make sure the de
vice mounted on the lifting machine can support the
weight to be lifted so as to carry out the operation in
complete safety.
