Description of the product and its use
The protective hood SH is a MOVABLE, SEPARATING PROTECTIVE
DEVICE as specified in EN 292-2, para. 4.2.2.3 and is used to
safeguard an action space which could give rise to a hazard.
Hazards
Under all circumstances, attention must be paid to the load limits given
under the heading “Technical data and hints for use”.
Additional information
The aim of the present User Manual is to enable users to employ the
protective hood SH correctly and safely. Should further information be
required in relation to your particular application, please contact the
manufacturer.
When reordering User Manuals, it is essential to quote the reference
number, the product name and serial number.

Technical Data and Hints for use
Nominal stroke (mm) *
Own weight per pillar (kg) *
Attached weight per pillar (kg) *
Torque Mxz max. (Nm) *
Myz max. (Nm) *
Permissible number of opening and
closing strokes with an attached
load of 20-25 kg per pillar 30/h
Ambient temperature (°C) 10...50
*These data are specific to the order concerned and shown on the nameplate
(300, Fig.16) mounted on the bearing pedestal (10 in Fig.16).
The hood must be opened and clo-
sed in such a way that no hard
impact occurs at the end stops. Hard
striking of the end stops shortens
their life, causes vibration in the
machine and may lead to the failure
of mechanical parts.
If the attached load exceeds 25 kg/pillar and/or if the number of
opening and closing strokes is more than 30/h, the drop guard
Ref.No. 43236 (Fig.24) must be fitted.

Transport Guard
In the state as delivered, every pillar of the protective hood is locked in its clo-
sed position by transport guard elements, which prevent the supporting spars
(20, Fig.16) from being moved.
Every time a hood is transported these guards must be fitted to secure the
moving parts.
Fitting the transport guards
On both pillars of the hood proceed as follows:
•If the columns are equipped with drop guards (43236, Fig. 12), the drop
guards must be secured by mounting the assembly aids (45459, Fig. 12) to
prevent unintentional catching.
•Move the supporting spar (20 in Fig.16) down and push the rod (120,
Fig.16) through the holes provided for it in the spar until it projects about
15 mm out at both ends. The guide roller holder (30, Fig.16) located bet-
ween the stop (230, Fig.16) of the supporting spar and the inserted rod
(120, Fig.16) secures the spar.
•To fix the counterweights of each pillar insert the rod (130, Fig.16) through
the hole through the bearing block (10, Fig.16) until it strikes the counter-
weight. The rod is then secured by tightening the screw (190, Fig.16).
To remove the transport guard
Caution: Before removing the transport guard, make sure the hood is properly
attached to the supporting spars (20, Fig.16) and that half the weight of the
hood is equal to the mass of the counterweight of each pillar to within 2 kg.
•Undo screw (190, Fig.16) so that the rod (130, Fig.16) can be pulled out at
the top.
•Pull out the rod (120, Fig.16).
•If the columns are equipped with drop guards (43236, Fig. 12), the assembly
aids (45459, Fig. 12) must be removed by loosening and unscrewing the two
M5 screws.

To transport the pillar a ring screw as per Fig.3 should be screwed into the
tapped hole provided (10, Fig. 16). The weight of the pillar is shown on the
nameplate (300, Fig.16).

Mounting the Hood
Since the hood stands on only two pillars, it must be secured by appropriate
means to prevent it toppling.
Optimal stability is obtained with a structure in which the pillars of the hood
are integral parts of the machine support. Fig.4 to 6 show examples of sup-
ports made of Quick-Set fixing elements.
Rigidity of the Hood
The synchronous shaft 47951 (Fig.16) allows the spars (20, Fig.16) to be
moved synchronously.
The superficial rigidity is assured by framing the upper and lower edges of the
pane in framing profiles 43943 as shown in Fig.4. To improve the strengt-
hening struts 45327/... as in Fig.5 may be used.
The maximum rigidity is obtained by screwing on a plastic cover as in Fig.6.
But owing to the heavy weight of the cover, this variant is not recommended for
retrofitting.
