E-Z DRILL 210B-2 SRA User manual

OPERATING INSTRUCTIONS FOR THE
MODEL 210B-2 SRA

SAFETY PRECAUTIONS FOR THE
MODEL 210B-2 SRA
System Under Pressure: Shut off air supply and disconnect air
hose before disassembling or disconnecting parts.
Flying Debris: During boring, chips may be ejected. Stay behind
control panel and wear safety glasses to prevent eye injury.
Pinch Points: Keep hand clear of carriage assembly. Hands or
fingers caught between carriage and frame may be seriously injured.
Moving Parts: When moving drill unit, use carriage lock to
prevent assembly from sliding onto hands or fingers.
Heavy Load: Use handles to reposition the drill unit. Weight of
the drill unit may cause back strain if improperly lifted.

SAFETY PRECAUTIONS FOR THE
MODEL 210B-2 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.

MOVING AND POSITIONING THE
DRILL
• After connecting the air hose from
the air compressor to the drill unit
(see SET UP instructions), release
the air brake by placing the toggle
switch on the control panel to the
“OFF” position.
• NOTE: The brake switch only
works when the air compressor is
attached to the drill unit, and the
air is turned on. If the air
compressor is not attached, the
brake assembly can be manually
released and pinned. It can be
placed in the locked position by
removing the cotter pin and
placing the brake assembly in the
wheel sprocket.

MOVING AND POSITIONING THE
DRILL
• Use the steering wheel and
manually push to position the
drill unit.
Heavy Load: Use handles
and steering wheel to
reposition the drill unit. Weight
of the drill unit may cause back
strain if improperly lifted.
• Move the drill unit to the edge
of the slab where the two
wheels along the edge are
parallel to the edge.

POSITIONING FOR HORIZONTAL
DRILLING
• Unlock the Safety Latch and all
Carriage Locks.

POSITIONING FOR HORIZONTAL
DRILLING
• Place the “Raise and Lower” valve
into the “LOWER” position.
•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.

POSITIONING FOR HORIZONTAL
DRILLING
• Place the “Auto Align” switch into
the “DOWN” position.

POSITIONING FOR HORIZONTAL
DRILLING
• At this point, the two 6” stop rods
should both be touching the face
of the concrete. If one or both are
not touching the concrete, the drill
unit is too close to the edge of the
slab, and you will need to
reposition a little farther away from
the edge.

SETTING AND ADJUSTING THE
FEED PRESSURE
NOTE: For the drills to drill properly, and at optimum drilling speed, you
may have to make some adjustments to the feed pressure on each drill. To
begin with, it easier to make this adjustment one drill at a time. After
making the desired adjustments to both drills, you can then start running
both drills simultaneously.

SETTING AND ADJUSTING THE
FEED PRESSURE
• To make the feed pressure
adjustment to the first drill (you
can start with either drill), place
the Feed Control Valve into the
“IN” position.

SETTING AND ADJUSTING THE
FEED PRESSURE
• Check the gauge on the control
panel. It should be set at
approximately 20 psi.

SETTING AND ADJUSTING THE
FEED PRESSURE
• To make an adjustment on the
Regulator, lift up the regulator
knob, and turn it clockwise to
increase the feed pressure, and
turn it counter-clockwise to
decrease the feed pressure. After
you finish, push the knob down
until it clicks.

SETTING AND ADJUSTING THE
FEED PRESSURE
• Next, place the corresponding
power switch into the “ON”
position. The drill will start drilling.
The drill should move forward into
the concrete with a slight “quiver”
as it drills. If it is “bouncing”, it
means it does not have enough
feed pressure. Lift up and slowly
turn the regulator knob clockwise
until the “bouncing” stops and you
still have good rotation on the bit.
Flying Debris: During boring, chips may be
ejected. Stay behind control panel and wear safety
glasses to prevent eye injury.
Loud Noise: Wear ear protection to prevent
eardrum damage from air compressor.
Dust: Wear a dust protection mask to protect from
concrete dust.

SETTING AND ADJUSTING THE
FEED PRESSURE
• If the bit is not turning freely, you
will need to decrease the feed
pressure by slowly turning the
regulator knob counter-clockwise
until the bit is turning freely.
• After setting the feed pressure at
the appropriate level, push the
regulator knob back down to lock
it into place.

SETTING AND ADJUSTING THE
FEED PRESSURE
• Repeat this procedure with the
other drill. After both drills have
been adjusted properly, you can
now operate both sets of controls
simultaneously . If the need
arises, you can always run each
drill individually.

SETTING AND ADJUSTING THE
FEED PRESSURE
• IMPORTANT: If the drill unit is set up to drill vertical holes, the feed
pressure will need to be reduced approximately 5-9 psi.
With the drill system in the vertical position, feed pressure set
too high can cause the drill unit to tip over.

DRILLING OPERATION
• After all adjustments have been
made and your are now ready for
production drilling, follow the next
steps in proper order to insure
maximum production and prevent
unnecessary damage to the drill.
• Place the Feed Control Valves in
the “IN” position.

DRILLING OPERATION
• After the bits make contact with
the concrete, place both power
switches into the “ON” position.
Both drills will start drilling.
Flying Debris: During boring, chips may be
ejected. Stay behind control panel and wear
safety glasses to prevent eye injury.
Loud Noise: Wear ear protection to prevent
eardrum damage from air compressor.
Dust: Wear a dust protection mask to
protect from concrete dust.

DRILLING OPERATION
• After each drill reaches its preset
drill depth, it is imperative that you
immediately turn that drill off. This
prevents “dry-firing” (the drill is
running with no pressure against
the bit), which can cause extreme
damage to the drill.
