6.3 Machine Set-Up
1. Remove toolbox and any accessory items from
around machine.
2. Make sure locking handles (A, Figure 6-4) on
head and column are tightened before lifting.
3. Place lifting straps as shown in Figure 6-4.
Use cushioning to protect machine surfaces.
Figure 6-4
4. Remove bolts holding machine to pallet.
All lifting equipment must
be rated appropriately to safely sustain the
weight of the drill press.
Do not allow
anyone near or beneath the machine while
it is being moved.
5. Lift machine and position it over the anchor
bolts in an area with good lighting, and a level
and well-supported floor.
6. Place the leveling pads beneath the level
adjusting bolts. Place a level (its tolerance
should be within 0.02mm/m) on box table and
level the machine.
7. The drill press MUST be anchored to floor.
Use the layout diagram in sect. 6.1 as a guide,
and mount the nuts to the ground bolts.
Failure to anchor the
machine properly, according to the
diagrams, could result in machine tipping
over and consequent damage to machine
and possible injury to machine operator
and bystanders.
8. Connect the electrical service branch to the
machine according to the instructions which
follow in
sect. 6.4. This work should be done
only by a qualified and licensed electrician who
is familiar with machine service and national
and local codes.
9. Turn on drill press (see sect. 8.0 ), release
upper locking handle, and move arm elevation
lever to UP, until quill clears the shipping
block. Remove shipping block from box table.
10. Wipe machine surfaces which have been
treated with a protective coating, using mineral
spirits or a cleaner/degreaser.
11. Inspect all sight glasses on machine to be
certain they are filled to their level lines. If low,
add fluid as necessary according to
instructions in
sect. 12.0.
12. Perform a lubrication check at all points
recommended in sect. 12.0 .
13. Follow directions in sect. 8.0 to check all
operation functions of the drill press. If coolant
is being used, put coolant in the sump and test
coolant delivery.
14. When all of the above operations are
complete, the machine is ready for service.
6.4 Electrical Connections
Electrical set-up should be
performed only by a licensed electrician who is
familiar with national and local electrical codes.
This machine must be properly grounded to
help prevent electrical shock and possible fatal
injury.
Model J-720R radial drills are tested before
shipping, for all functions and circuits under
electrical power specified for the machine and
motors. The only hook-up requirement should be
for correct connection to an appropriate cutout on
an appropriate service branch.
Where the following instructions do not agree with
local electrical codes and procedures, the
applicable codes and procedures should be
followed, exclusively.
6.4.1 Wiring diagram
A wiring diagram for the drill press is found inside
the door of the electrical cabinet. It is also shown at
the back of this manual. This diagram is for
reference by your licensed installing or servicing
electrician. In addition to using a licensed
electrician for connection to the drill press service
branch, the servicing of components and circuits
inside the control box should be serviced only by a
qualified
electrician. This includes fuse
replacement, if required. If any of these fuses,
upon replacement, should continue to fail at short
service intervals, the electrician should be asked to
check all machine components for excessive loads,
short circuits or other failures.
6.4.2 Electrical branch service
The machine is wired for either a 230V or 460V 3-
phase service branch. The cable supplying the drill
press will be tagged with the voltage at which the
machine was tested and corresponding to the
customer's order.
