Drill Starter Hole
A starter hole will have to be drilled in order to insert (start) the Nibbler. Take care to ensure
the starter hole does not encroach or expand past the portal hole outline.
PRIOR TO DRILLING OR CUTTING A CAGE PANEL, ALWAYS INSPECT the space
between the cage panels to be sure there are no electrical wires or other obstructions
present. Cutting into live wires or other obstructions can result in electrical shock
which will cause SERIOUS PERSONAL INJURY OR DEATH or property damage.
The punched indention helps center the drill bit in place. Care should be taken when
drilling holes in steel, as the drill bit can release from the punched indention and
scratch the cage surface.
STEP 1:
Use a power Drill and a 1/4" Drill Bit to start a hole at a size that will accept a Step
Drill Bit. See FIGURE 2.10
FIGURE 2.11 - Step Drill
FIGURE 2.10 - Starter Hole
STEP 2:
Use a power Drill and Step Drill Bit to increase the hole to a size that will accept
the cutting head (Up to 7/8"). See FIGURE 2.11
STEP 3:
Remove metal shavings and clean the cage of debris.
Portal Hole Cut
DO NOT use a plasma cutter to cut the Portal hole. Plasma cutters can create excessive
heat that can result in severe burns or fire which will cause SERIOUS PERSONAL
INJURY OR DEATH.
PRIOR TO DRILLING OR CUTTING A CAGE PANEL, ALWAYS INSPECT the space
between the cage panels to be sure there are no electrical wires or other obstructions
present. Cutting into live wires or other obstructions can result in electrical shock
which will cause SERIOUS PERSONAL INJURY OR DEATH or property damage.
Installation of the Portal MUST BE COMPLETED BY A QUALIFIED INSTALLER familiar
with sheet metal manipulation/modifications. Cutting or drilling into metal cages can
produce sharp or jagged edges which could cause serious lacerations which, if not
avoided, could result in SERIOUS INJURY OR DEATH.
