On drive-lines with torque limiting or overrunning devices, specify that the device be
positioned on the end of the drive-line by the implement.
For implement connections which require bolts or set screws, select and/or supply
hardware which minimizes protrusions.
For tractor PTO shaft connections, specify a safety type yoke (twist or slide collar) to
minimize protrusions.
Provide a proper clearance zone for the operation of the drive-line to avoid damaging
the shielding components.
Some common areas of interference are:
Three point linkage.
Extended or eye loop hitch pins.
Hydraulic hoses.
GUARDING
Hazards which cannot be eliminated effectively must be
guarded against at all times.
The PTO master shield, integral drive-line shield and implement input connection
shield should provide an interactive guarding system.
Provide instructions by labels or manuals. The implement should be used only with
the tractor’s PTO master shield in place.
Specify and test an integral drive-line shield with end cones which will overlap, but not
interfere with the PTO master shield or implement input connection shield.
Provide an implement input connection shield to interact with the integral drive-line
shield to provide guarding of the shaft coupling and any torque limiting device installed
on the drive-line.
Check that all routine maintenance of the drive-line can be done without removal of
the shields.
MACHINE OPERATION
CAUTION!
Turn the chipper head over by hand before applying power to make
sure that the head is clear, all the bolts are clear and the knives clear the case and cutter
bar.
CAUTION:
Do not move the unit while the flywheel is turning. Block the wheels and
set the brake while running the head.
