PRE OPERATION PROCEDURES
PREPARATION FOR INITIAL USE
The tool as shipped has no special unpacking or
assembly requirements prior to usage. Inspection to
assure the tool was not damaged in shipping and that
it does not contain packing debris is all that is required.
Otherwise, the tool may be connected to a hydraulic
source upon receipt.
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated owmeter and pressure gauge,
check that the hydraulic power source develops a
ow of 8–10 gpm/30–38 lpm at 2000 psi/140 bar.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2200–2300 psi/152–
159 bar maximum.
3. Make certain that the power source return pressure
does not exceed 250 psi/17 bar.
CONNECT HOSES
1. Wipe all hose couplers with a clean lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power source
to the hose couplers on the tool. It is a good practice
to connect the return hose rst and disconnect it last
to minimize or avoid trapped pressure within the
tool.
3. Observe ow indicators stamped on hose couplers
to be sure that oil will ow in the proper direction.
The female coupler is the inlet coupler.
4. Observe the IN and OUT port lettering on the valve
block assembly to ensure that the hydraulic ow is in
the proper direction. The IN port lettering indicates
the inlet (pressure) side.
NOTE:
The pressure increase in uncoupled hoses left in the
sun may result in making them difcult to connect.
When possible, connect the free ends of operating
hoses together.
USING COOLANT
The RD12 rail drill is equipped with a separate coolant
can assembly that is used to deliver coolant to the drill
bit. Follow the instructions below to use the coolant can
assembly with the rail drill:
1. If operating the rail drill at temperatures above
32 °F/0 °C, ll the coolant can with ordinary tap
water.
2. If operating the rail drill at temperatures below
32 °F/0 °C, ll the coolant can with a mixture of
50% ordinary tap water and 50% biodegradable
antifreeze.
3. Pressurize the coolant can using the carrying
handle/pump.
4. Connect the coolant can assembly to the rail drill
using the supplied quick-disconnect coupler.
OPERATING PROCEDURES
1. Observe all safety precautions.
2. Make sure the drill bit you intend to use contains
carbide inserts with good cutting surfaces. If the
surfaces are worn or chipped, unscrew the retaining
screw and rotate the insert to a good cutting surface.
If the inserts do not contain a good cutting surface
on one of the four sides, replace the inserts. Make
sure the bit holder is not damaged.
3. Install the drill bit into the piston machining assembly
(24) and then turn it clockwise until it stops.
RAIL TEMPLATES & HOLE GUIDES
NOTE:
The RD12 must be used with rail templates and hole
guides. See the chart at the end of this section for
selections of rail templates and hole guides.
1. Install a hole guide assembly onto the rail and
position it where you want to drill.
2. Install templates onto the rail drill with the rail size
facing the rail.
NOTE:
To avoid drill bit damage, make sure the drill bit/
piston assembly is fully retracted prior to placing
the RD12 on the rail.
3. Set the rail drill over the hole guide on the rail so that
the templates are nested between the ball and the
base of the rail and the adjustment screw (52) ts in
a slot in the hole guide.
4. Adjust the threaded shaft (44) until there is no
movement of the rail drill as it sits on the rail and
the hole guide. Wiggle the RD12 to remove all
looseness. Then lift the handle (49) up and turn the
threaded shaft (44) clockwise approximately 1/2
turn. Push the handle (49) down hard to rmly clamp
the RD12 to the rail.

• Make sure all couplers are wiped clean before
connection.
• The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydraulic
tools. Failure to do so may result in damage to
the quick couples and cause overheating of the
hydraulic system.
• Always store the tool in a clean dry space, safe from
damage or pilferage.
• Make sure the circuit PRESSURE hose (with male
quick disconnect) is connected to the IN port. The
circuit RETURN hose (with female quick disconnect)
is connected to the opposite port. Do not reverse
circuit ow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts
with replacement parts recommended by STANLEY.
Supply hoses must have a minimum working
pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow (see Specications) in
this manual for correct ow rate and model number.
Rapid failure of the internal seals may result.
• Always keep critical tool markings, such as warning
stickers and tags, legible.
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.
• Tool repair should be performed by experienced
personnel only.
• Make certain that the recommended relief valves
are installed in the pressure side of the system.
• Do not use the tool for applications for which it was
not intended.
TOOL PROTECTION & CARE

16 ► RD12 User Manual
If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.
When diagnosing problems with operation of the drill, always check that the hydraulic power source is supplying
the correct hydraulic ow and pressure to the tool as listed in the specications. Use a owmeter known to be
accurate. Check the ow with the hydraulic oil temperature at least 80 °F/27 °C.
PROBLEM CAUSE SOLUTION

functioning.
Check power source for proper ow and
pressure, 8–10 gpm/30–38 lpm, 2000
psi/140 bar.
Couplers or hoses blocked. Locate and remove restriction.
Hydraulic motor failure. Inspect and repair.
Hydraulic lines not connected. Connect lines.
Drill bit dulls quickly. Incorrect oil ow. Check that 8–10 gpm/30–38 lpm at 2000
psi/140 bar is available at the rail drill.
Using insufcient amount of
coolant.
Rotate or replace insert. Increase ow of
coolant. Make sure pressure tank is fully
pumped up. Check for plugged water port
in drill bit. Check for a clogged inlet lter.
Remove pipe plug in end cap and ush
with water. Remove end cap and clean
lter.

Not clamped properly. See clamping instructions.
Inserts chipped. Some chipping is normal,
particularly on the inside insert.
Rotate or replace if poor hole nish is
noted.
Incorrect template. Use correct template and verify t.
Using insufcient amount of
coolant.
Rotate or replace insert. Increase ow of
coolant. Make sure pressure tank is fully
pumped up. Check for plugged water port
in drill bit. Check for a clogged inlet lter.
Remove pipe plug in end cap and ush
with water. Remove end cap and clean
lter.
