FOR OPERATING  MACHINERY

WARNING

As with all machinery, there are certain hazards involved with their operation and

and limitations, as well as the specific potential hazards peculiar to it.

REMOVE ALL ADJUSTING KEYS AND WRENCHES. Before starting, form the habit of checking
to ensure that keys, wrenches and tools are removed from the machine.

or expose them to rain. Keep work area well lit.

18. CHECK FOR DAMAGE. If part of the machine  (eg. A cover or guard), is damaged, it

should be carefully inspected to ensure that it can perform its’ intended function
correctly.  If in doubt, the part should be renewed. Damage to moving parts or major
