CHAINS (FIGS. G1 - G3)
NOTE: The chain is intended to prevent
the shield from rotating against non-moving
parts and thereby preventing shield damage.
A properly installed chain will increase the
service life of the shield.
1.
Chains must be fi tted so as to allow suf-
fi cient articulation of the shaft in all working
positions. Care must be taken to be sure
that chain does not become entangled with
drawbar hitch or other restrictions during
operation or transport of
machine.
2. The PTO drive shaft must not be sus-
pended from the chain.
G2
SHEAR BOLT AND FRICTION
CLUTCHES (FIGS. H1 - H2)
1.
Shear bolt clutches:
When the torque is exceeded, power fl ow
is interrupted due to the bolt shearing.
The torque is re-established by replacing
the broken shear bolt. Use only the bolt
specifi ed in the operator's manual for re-
placement.
2. Friction
clutches:
When overload occurs, the torque is limited
and transmitted constantly during the period
of slipping. Short-duration torque peaks are
limited.
Prior to fi rst utilization and after long
periods out of use, check working of
disk clutch.
a. Tighten nuts until friction disks are
released. Rotate clutch fully.
b.
Turn nuts fully back. Now the clutch
is ready for use. Fig. H
