SAFETY PRECAUTIONS FOR THE
MODEL 210B SRA (continued)
Loud Noise: Wear ear protection to prevent eardrum damage
from air compressor.
Dust: Wear a dust protection mask to protect from concrete dust.
High Pressure: High pressure from the air compressor can
damage the drill, and can void the warranty.
Lifting The Drill Unit: when using a lifting device to pick up the
drill unit, use a strap or chain which is rated for the proper weight,
and attach to the lifting bale on the drill unit. Be sure carriage lock is
in place.

ATTACHING THE HOSE THE DRILL UNIT
• The Model 210B SRA requires a minimum ¾” hose and
a minimum of 100 cfm of air.
• Make sure all safety precautions are followed with the
hose and all hose connections.
• IMPORTANT: AIR COMPRESSOR MUST MAINTAIN
100-110 PSI WHILE ALL DRILLS ARE DRILLING

SET UP FOR THE
MODEL 210B SRA
• Always keep the lever on the rock
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.

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 open
the Power lever 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
wrench provided on the side of
the control panel.

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

INSTALLING THE DRILL BITS
• Place the bit into the chuck
and close the latch.
• Close the bit guide around the
bit and tighten the swivel bolt.

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, 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 guide plates.
• Newer models have guide
wheels installed in place of the
guide plates. These wheels
are also adjustable.

ADJUSTING THE HEIGHT OF THE DRILL
SYSTEM
• 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 ½” x
1 ½” bolts on the sides of the
mast.

ADJUSTING THE HEIGHT OF THE DRILL
SYSTEMS
• Again, you can use the wrench
provided with the drill unit to turn
the nut at the top of the mast. As
soon as you have adjusted the
mast to the required height, re-
tighten the bolts on the side of the
mast.
• NOTE: It is easier to turn the
screw jack when the drill is in the
vertical position, but you will need
to lower the drill 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

LEVELING THE DRILL SYSTEMS
IMPORTANT: BEFORE LEVELING THE DRILL SYSTEMS, CONFIRM
THE ANGLE REQUIRED. MANY TIMES THE DRILL SYSTEM IS NOT BE
“LEVEL WITH THE WORLD”, THEY SHOULD BE SET DRILL PARALLEL
WITH THE TOP OF THE CONCRETE SLAB INTO WHICH YOU ARE
DRILLING.

LEVELING THE DRILL SYSTEMS
• On the all-thread coming out of
the bottom of the Auto Align
cylinder, turn the top nut to
change the angle of the drill
system.

LEVELING THE DRILL SYSTEMS
NOTE: THIS ADJUSTMENT WILL BE REQUIRED ANYTIME YOU HAVE
BEEN DRILLING HORIZONTAL HOLES, AND WANT ADJUST TO DRILL
STRAIGHT VERTICAL HOLES, OR VICE VERSA.

SETTING THE DRILL DEPTH
• To adjust the drills to ensure
the desired depth, make sure
all other adjustments have
been made and the air supply
is connected to the drill.
Maneuver the drill to the edge
of the concrete slab.
Heavy Load: Use handles to
reposition the drill unit. Weight
of the drill unit may cause back
strain if improperly lifted.

SETTING THE DRILL DEPTH
• MAKE SURE AIR SUPPLY IS ON
TO THE DRILL UNIT, AND THE
“RAISE & LOWER” VALVE IS IN
THE “RAISE” POSITION
BEFORE DOING THE NEXT
STEPS.
•Pinch Points: Keep hand clear of
carriage assembly and Raise & Lower
Cylinder. Hands or fingers caught
between moving parts of the frame
may be seriously injured.
• Unlock the red safety latch on
the Raise & Lower cylinder by
removing the lock pin.
Remove the carriage lock.
