SET UP FOR THE
MODEL 210B-2 SRA
• Always keep the lever on the drill
motor shown at right in line with
the drill motor.
• If the lever is in the position shown
at right, the air will be shut off from
the drill motor and will not run.

ATTACHING THE HOSE THE DRILL UNIT
• The Model 210B-2 SRA comes with 20’ of the 1 ¼” ID
hose. If you are going to add more hose, do not use
hose that is smaller in diameter.
• Make sure all safety precautions are followed with the
hose and all hose connections.
• IMPORTANT: AIR COMPRESSOR MUST MAINTAIN
120 PSI WHILE ALL DRILLS ARE DRILLING

INSTALLING THE DRILL BITS
System Under Pressure: Shut off air
supply and disconnect air hose before
disassembling or disconnecting parts.
(to remove pressure from system, have air
supply disconnected from drill unit, and turn
the power switches to the “On” position)
• IMPORTANT: The chuck size of the
drill bits must match the chuck size of
the drill. Look for the decal on the side
of the drill motor to confirm the chuck
size. Most E-Z Drill models come
standard with 7/8”x 3 ¼” chuck.
However, a 7/8” x 4 ¼” chuck and 1” x
4 ¼” chuck are available on request.
• All 210 series E-Z Drill models use 6”
of the usable length of the bit (i.e. a
24” bit will drill up to 18” deep; an 18”
bits will drill up to 12” deep.

INSTALLING THE DRILL BITS
• IMPORTANT: You must have the
correct bit guide bushing to match
the bit you will be using:
For drilling a:
5/8” diameter hole, use 1108 MCP
3/4” diameter hole, use 1109 MCP
7/8” diameter hole, use 1110 MCP
1” diameter hole, use 1111 MCP
1 1/8” or larger diameter hole, use
1112 MCP
• Part numbers above will fit bits
with either 7/8” x 3 ¼” or 7/8” x 4
¼” chucks. For 1” x 4 ¼” chucks,
see parts book.

INSTALLING THE DRILL BITS
• To install a drill bit, loosen the
swivel bolt until you can swing it
out away from the lower bit guide.
• NOTE: You can use the
wrenches provided found next to
the mast.

INSTALLING THE DRILL BITS
• Open the retainer latch on the drill
motor.
• Pinch point

INSTALLING THE DRILL BITS
• Place the bit into the chuck and
close the latch.
• Pinch point

INSTALLING THE DRILL BITS
• You may have to adjust the return
stop rod so that the end of the bits
clears the bit guide.

INSTALLING THE DRILL BITS
• To adjust the stop rods, use the
wrenches provided to loosen the
stop rod nuts. Move the stop rod
in the direction needed to the
required location and re-tighten
the nuts.

INSTALLING THE DRILL BITS
• If you are using 2-piece H-thread
bits, you may also have to adjust
the stop rod bolts.

INSTALLING THE DRILL BITS
• Place the proper bushing into the
bit guide; one half in the upper bit
guide and one half in the lower bit
guide. Close bit guide, swing the
swivel bolt back onto the bit guide,
and tighten.
• Repeat for the other drill system.

ADJUSTING THE DRILL SPACING
• IMPORTANT: Regardless of the
spacing, always keep the drill
systems centered with the
mainframe so that the entire unit
remains balanced.
• NOTE: You can adjust the spacing
with the drill systems in the
horizontal or vertical position.

ADJUSTING THE DRILL SPACING
• To slide a drill system one way or
the other to reach the required drill
spacing, you must first loosen the
5” frame clamps on each end of
the feed bar. Loosen all four four
½” lock nuts on each frame clamp
until you can slide the feed bar.
• Pinch point
• Heavy load

ADJUSTING THE DRILL SPACING
• To get the proper spacing,
measure from one side of the feed
bar to the same place on the
adjacent feed bar.

ADJUSTING THE DRILL SPACING
• Be sure to measure from both
ends of the feed bar to insure the
drill systems are parallel to each
other.
• After moving the proper distance,
re-tighten all on the frame clamps.
• Heavy load

ADJUSTING THE HEIGHT OF THE DRILL
SYSTEMS
• Adjusting the height of the drill
systems is done by turning the
mast screw jack assembly located
at the top of the mast. Before
turning the screw jack, you must
first loosen the four ½” x 1 ½”
bolts at the base of the mast.

ADJUSTING THE HEIGHT OF THE DRILL
SYSTEMS
• Use a 1 1/2” wrench (preferably a
socket wrench) to turn either of the
nuts at the top of the mast (the two
screw jacks are connected with a
chain, so it does not matter which one
you use to make the adjustment). As
soon as you have adjusted the mast to
the required height, re-tighten the four
bolts at the base of the mast.
• NOTE: It is easier to turn the screw
jack when the drills are in the vertical
position, but you will need to lower the
drills into the horizontal position to
check for proper height.
•Activating this control will cause the
drill system lower down to the
horizontal position. Make sure
everyone is clear of the drill unit before
lowering the drill system
