SAFETY PRECAUTIONS
CUTTING WHEEL SAFETY
• Do not store or transport the saw with the wheel installed.
• Ensure that the cutting wheel is correctly mounted
and tightened before use.
• Operate the Rail Saw at “no load” for 30 seconds in
a safe position and ensure there is no vibration or
other defects detected. If considerable vibration or
other defects are detected, stop operation of the tool
immediately and determine the cause. Do not use
the tool until the defect is corrected.
• If the Rail Saw is dropped with a cutting wheel installed, the cutting wheel should be examined thoroughly before use.
• Only use cutting wheels that comply with ANSI B7.5/
ISO 525, 603.
• Check that the maximum operating speed (rpm –
revolutions per minute) of the cutting wheel is equal
to or greater than the rated shaft speed of the grind-
er. Stanley recommends wheels rated at 4700 RPM
for 16 inch models and 5300 RPM for 14 inch models.

1. Using a calibrated owmeter and pressure gauge,
check that the hydraulic power source develops a
ow of 9–10.5 gpm/34–40 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 minimum.
3. Check that the hydraulic circuit matches the tool for
open-center (OC) operation.
CHECK TOOL
1. Make sure all tool accessories are correctly installed. Failure to install tool accessories properly
can result in damage to the tool or personal injury.
2. There should be no signs of leaks.
3. The tool should be clean, with all ttings and fasten-
ers tight.
CHECK TRIGGER MECHANISM
1. Check that the trigger operates smoothly and is free
to travel between the ON and OFF positions.
CHECK GUARD ASSEMBLY
1. Inspect the wheel guard assembly for cracks and
other structural damage.
INSTALLING AND REMOVING
ABRASIVE CUTTING WHEELS
NOTE:
Use 14 in./350 mm diameter (for 14 in. model) or 16
in./400 mm diameter (for 16 in. model) abrasive cutting wheels with a 1 in. arbor hole. Only use cutting
wheels which comply with ANSI B7.5/ISO 525, 603.
Make sure the paper labels or blotters are installed
between the wheel and collars.
1. Before installing abrasive wheels, “sound” the wheel
for possible damage by hanging the wheel vertically
be the arbor hole and rapping lightly with a screwdriver handle or similar instrument. Thin, organic
bond wheels will produce a low drumming tone if it
is physically sound. If the wheel produces a “dead”
or “at” sound, it may be cracked. Cracked or damaged wheels must never be used.
2. Check that the surfaces of the wheel that come in
contact with blotters and anges are free of dirt and
other foreign particles.
3. Remove the jam nut (77) and outside collar (78) by
using a box type wrench while gripping the cutting
wheel.
4. Install the cutting wheel. Make sure blotters or labels
remain on the cutting wheel.
5. Reinstall the outside collar and jam nut. Tighten the
jam nut with a box type wrench while gripping the
cutting wheel. Only tighten sufciently to prevent
slippage of the wheel between the collars (78 & 79).
DRIVE SHAFT SPEED CHECK
The speed of the motor output shaft should be checked
at least every 100 hours of operation by trained and
experienced personnel. A record of the speed checks
should be maintained. The rated speed of the RS25 Rail
Saw is 3600 rpm at 10 gpm/38 lpm for the 16 inch/400
mm model and 4500 rpm at 10 gpm/38 lpm for the 14
inch/350 mm model. The cutting wheel must be rated for
a minimum of 4700 rpm for the 16 inch/400 mm model and 5300 rpm for the 14 inch/350 mm model. Tests
should be conducted while operating the normal power
supply used with the saw.
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 rail saw. It is a good
practice to connect the return hose rst and disconnect it last to minimize or avoid trapped pressure
within the rail saw motor.
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.
NOTE:
The pressure increase in uncoupled hoses left in the
sun may result in making them difcult to connect.
When possible, connect the free ends of operating
hoses together.

OPERATING PROCEDURES
CLAMPING THE RAIL SAW TO THE RAIL
1. Observe all safety precautions.
2. Make sure the rail clamp assembly is tight to the
disconnect pivot (60) by turning the handle (20) to
tighten the disconnect pivot bolt.
3. Fully extend the indicator rod located on the clamp
and position the rail clamp on the rail so the clamp
arms bear on the top and sides of the rail and the
bell crank bears under the rail as shown in Figure 2.

6. While holding onto the upper link of the rail clamp
assembly (near the red knob of the handle), release
the detent (129) by turning the knob and then position the lower link forward (away from the operator)
until the detent can be re-engaged in one or the other of the two holes away from the “top dead center
hole”. This positions the saw so that the operator
may stand erect while cutting the rail and also allows
the saw to cut down to the ange of the rail.
An optional method is to disengage the detent and
adjust the capscrews (see Figure 2) as required.
7. Adjust the wheel guard (87) so that it does not interfere with the cutting process and cuttings are directed away from the operator.
SAWING THE RAIL
1. Always start the rail saw with the cutting wheel away
from the work surface.
2. Start the cut with the wheel rotating.
NOTE:
Do not “bump” the rail. Feed the wheel through
the material as fast as possible without allowing
the wheel to reduce its speed. Cutting through the
material too slowly allows heat expansion and can
cause wheel “pinching” in the material. “Pinching”
the wheel from heat expansion is one of the most
common causes of wheel breakage.
3. Starting at the top of the rail, cut straight down while
rocking the handle back and forth. Cut down until
near the ange.
4. When near the ange, stop the saw, release the de-
tent and move the lower link toward the operator until the detent can be re-engaged in one of the holes
away from the “top dead center hole”. This positions
the saw lower so that the ange of the rail may be
easily cut.
If the detent has been removed in favor of using the
capscrews as stops for the lower link, simply move
the lower link toward the capscrew closest to the operator.
If the wheel is worn such that it will not completely
cut through the rail, loosen the clamp lever on the
saw, and rotate the saw to allow cutting from the opposite side. Readjust the lower link as required and
nish the cut.

CAUTION
OPERATION
DETACHING THE UPPER AND LOWER
LINKS
The upper and lower links of the rail clamp assembly
can be detached from the motor mount (50) by unscrewing the handle (20).
SAW STORAGE
By disengaging the double cam (52), the rail clamp as-
sembly can be rotated so that the entire saw has a atter
prole for storage.
Do not store the saw with the abrasive wheel attached.
CARE OF ABRASIVE CUT-OFF WHEELS
All abrasive cut-off wheels are breakable and,
therefore, care must be exercised during handling
and storage to prevent damage.
Wheels should be laid on a at, rigid, surface away from
excessive heat or moisture. Wheels should not be stored
where they will be exposed to high humidity, water, other
liquids or freezing temperature. If wheels are supplied
with blotters attached, suitable separators should be
used to preserve atness.
COLD WEATHER OPERATION
If the saw is to be used during cold weather, preheat
the hydraulic uid at low engine speed. When using the
normally recommended uids, uid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes) before use.
INVESTIGATION OF WHEEL
BREAKAGE
If a wheel breaks during use, a careful investigation
should be conducted by to determine the cause of the
breakage. The cause must then be corrected before using the saw again.
If unable to determine the cause of breakage, the wheel
manufacturer should be consulted.

NOTICE
TOOL PROTECTION & CARE
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.
• 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 couplers 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 cir-
cuit ow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts
with replacement parts recommended by Stanley
Hydraulic Tools. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow (see Specications) in
