9. Safety guard assembly
Attach hinges (W) to supports (X) using 4 hexagon
screws (I) (M12 x 35) and 4 self-locking nuts (M12)
(Torque = 10 daN.m/75 ft.lbs) (photo 20).
Mount folding guards (Z) to hinges (W) with roll pins
(O) (dia. 8 x 55) (photo 20) and (O') (dia. 8 x 55)
(photo 21). Do not forget to insert spacer washer (R)
(dia. 40 x 51 x 7) between roll pins (O) and hinges (W)
(photo 20).
When mounting the foldable guards
(Z), make sure the lock rods (T) are
located underneath the safety guard
when in working position (photo
21).
Install the 4 clips (C) on side beams (W) by means
of 4 hexagonal screws (M 8 x 55) and 4 self-locking
nuts (M 8) using the handles (K) as templates.
Then mount inner safety guards (D) to hinges (W)
using 2 hexagon screws (E) (M 10 x 60). Do not
forget to insert conical spring washers on both sides
of safety guard tubing (photo 21).
After assembly, make sure each
safety guard locking system works
correctly.
10. Fitting tine arms and tines
First fit tine arms (E) to supports (S) and secure
using linch pins (U) (fig. 22).
Connect the small hook of safety strap (X) to linch pin
(U), then connect the large safety strap hook to the
hole (A) of bracket (W) on tine arm (E) (fig. 22).
Next fit the supports (S) with tine arms on the
oscillating shafts (L) using roll pins (V) (dia.12 x 55
and 7 x 55) (fig. 22A).
The right and left-hand rotor arms are symetrically
curved to one another. Ensure they are posi-
tioned so that the curved portion is facing the
front as seen in the direction of rotation (see
arrows figure 23) and the flattened side of the
tine arms must always be positioned on the top
side.
ATTENTION : Make sure slots of roll pins are ori-
entated opposite to one another and
in the direction of main effort (see
drawing on figure 23).
Clean and apply regularly a «Never-
Seize» compound to the detachable
tine arm ends (E) (fig. 22) (see also
page 26).
