push the red collar of the connector and pull the tube out.)
Cutting coolant fluid is always required when
using annular cutters. Open tank cover and fill. Check coolant fluid level often. Keep coolant tap closed when
not in use.
Chip guard must be used.
To attach the chip guard, use the supplied butterfly bolts to bolt to the magnet. It
is not necessary to remove guard to clean chips. Simply raise guard to its upper position.
Safety chain must be used.
Loop chain around the work piece and feed through the machine’s handle and
clip in place.
MOUNTING ANNULAR CUTTERS
CAUTION: Never use a cutting tool that is larger than the maximum rated capacity of the machine.
1.
To insert an annular cutter, first insert the pilot pin into the
cutter. Then slide the cutter into the arbor, align the proper
flat with the locking screw(s) and tighten securely with the
supplied hex wrench.
CAUTION: Ensure that the locking screw is on a flat of the cutter
and not just against the rounded shank.
2.
Ensure that the oil feed tap is on and coolant feeds properly by
pushing the pilot pin. If it feeds too quickly or slowly, adjust the tap accordingly. Keep the tap closed
when not in use.
2-SPEED MODELS
GEAR SELECTION
On 2-speed models, before drilling select desired gear range by first pushing in on
spring-loaded gear selector slider switch and then sliding selector up for high
speed or down for low speed. (It may be necessary to turn the arbor slightly in
order for the gears to mesh properly). Follow the recommended speed ranges on
the cutting speed chart to set the proper speed and gear range.
