6Commissioning and operation
6.1 General information for start-up
DANGER
Incorrect operation of the machine or disregard of safety instructions may lead to
endangerment of persons or damage to the machine.
-Familiarize yourself with the complete instruction for use before beginning work on the
machine. Pay particular attention to chapter 3!
NOTE
A thorough, visual inspection of the machine is to be carried out by the operator before start-up.
Start-up of the machine may only be carried out by qualified specialist personnel. The start-up engineer must be acquainted with
the machine. Requirements for start-up are:
If the tool is used in cold weather, preheat the hydraulic fluid by running power source at low engine speed. Fluid temperature
should be at or above 50° F/10° C (400-ssu/82 centistroke) before use, when using recommended fluids. Using too thick of fluid
may result in tool damage.
all detachable connections have been checked and tightened if necessary
check for loose nuts and bolts, keep all fasteners tight to prevent parts from separating and causing unsafe conditions
check hydraulic fittings and hoses for leaks or damage. Keep all hydraulic components in good condition to prevent tool
failure and for operator safety
CAUTION
Do not search for leaks with bare hands. Pressurized fluid escaping from a damaged hose
or fitting can penetrate the skin and be injected in the body causing injury or death.
-Wear appropriate work gloves.

18
RAIL SAW SR-10-26-O & SR-10-26-1 ORIGINAL OPERATION MANUAL
6.1.1 Tool preparation
Hydraulic system
-Use calibrated flow meter and pressure gauge to check the hydraulic power source. The source should provide a flow of 10
gpm/40 lpm at 2000 psi/ 140 bar. A relief valve setting between 2100-2250 psi/ 145-155 bar is required for the operation of
this tool.
-The hydraulic system’s back pressure should be less than 250 psi/17 bar, measured at the end of the tool’s operating hoses. All
systems checks should be made at minimum operating temperatures (maximum fluid viscosity of 400 ssu/82 centistokes).
-The hydraulic fluid cooling system should limit the maximum fluid temperature to 140º F/60º C at the maximum expected
ambient temperature. The minimum cool capacity should be 5hp/3.73 kW at the 40 º F/22 º C difference between ambient
temperature and fluid temperature.
-A minimum of 25 micron filtration is required for the hydraulic system. For cold weather startup and maximum dirt holding
capacity a filter element sized for 30gpm/120 lpm is recommended.
-If the tool is used in cold weather, preheat the hydraulic fluid by running power source at low engine speed. Fluid temperature
should be at or above 50 ºF/10 ºC (400ssu/82 centistokes) before use, when using recommended fluid.
CAUTION
Using too thick of fluid may result in tool damage.
The PortaCo G-18D55-53-W power unit is recommended for hydraulic supply. This unit is equipped with two 5 gpm/20 lpm circuits
that can be combined for one 10 gpm/40 lpm circuits.
Tool trigger and trigger lock
-Check that trigger lock presses into handle tube easily and returns to locking position when released.
-Check that trigger cannot be activated with trigger lock in the released position.
-With the trigger lock pressed into the handle tube, pull the trigger to the tube. The trigger should return to the “Off” position
when released.
-If trigger or trigger stop sticks or doesn’t operate easily check for obstructions. If trigger or trigger lock doesn’t return to “Off”
or lock position when released, check the return springs.
WARNING
Do not operate a tool if the trigger or trigger lock is not working properly!

19
RAIL SAW SR-10-26-O & SR-10-26-1 ORIGINAL OPERATION MANUAL
Blade guard
Inspect the blade guard and fasteners for damage. Repair any damage before using the tool.
WARNING
Do not operate tool without the wheel guard!
Blade backups
-If reducing bushings are used in a blade’s mounting hole, check that it doesn’t protrude beyond the surface of the blade.
Bushings that are too thick will not allow the backups to contact the blade properly.
-Do not use blades that have bushings which are loose in the mounting holes. Do not use shim shock to tighten or replace
bushings.
Reducing bushings
-If reducing bushings are used in a wheel’s mounting hole, check that it doesn’t protrude beyond the surface of the wheel.
Bushings that are too thick will not allow the backups to contact the wheel properly.
-Do not use wheels that have bushings which are loose in the mounting holes. Do not use shim stock to tighten or replace
bushings
Blade inspection
-Prior to mounting, all wheels should be visually inspected by the operator for damage and cracks.
WARNING
Do not use damaged or cracked tool blades.
-The “ring test” may be used to check for cracks in the blade which are not visible to the naked eye. To perform the test
suspend the blade from the hole on a small pin or finger. Tap the blade gently with a non-metallic implement such as a
screwdriver handle. The best spot to tap is about 45º either side of the vertical center line 1” or 2” from the periphery. An
undamaged blade will give a clear tone. If cracked there will be a dead sound instead.
-Check that the surface of the blotters and backups are free of dirt and other foreign contaminants.
-Use only blades which meet or exceed the requirements of the tool.

20
RAIL SAW SR-10-26-O & SR-10-26-1 ORIGINAL OPERATION MANUAL
Care of abrasive wheel
-All abrasive blades are breakable and therefore care should be exercised in handling and storage to prevent damage. All
abrasive blades should be stored in a dry area and not be subjected to exposure to water or other solvents. Also avoid freezing
temperatures or humid conditions which cause condensation on the blades.
-Thin organic bonded blades, (Rail Saw blades or Slotting discs used for cutting), should be laid flat on a flat surface of steel or
similar rigid material away from excessive heat, moisture, and other liquids. If thin blades are supplied with blotters attached,
suitable separators should be used to preserve flatness.
-Blades used on cutoff saws carried on emergency vehicles should be removed after use and discarded or carefully stored as
described in this section
Wheel breakage
-If a blade breaks during use, the operator should investigate to determine and correct the cause. If the operator cannot
determine the cause, the blade manufacturer should be consulted.
-Blades designed for use with hand-held portable tools are reinforced and specifically manufactured for this application. They
are extremely tough and difficult to break under normal use.
6.1.2 Testing
WARNING
Never stick foreign objects, fingers, or other extremities into moving mechanisms. Failure to follow these
instructions may lead to severe personal injury or tool damage.
-Mount the rail saw clamp to a test rail. Position the clamp so the cut off piece is only about 1 inch wide.
-Mount the saw to the clamp.
-Install a new cut off blade in the saw
-Connect the saw to the power source. Run the saw at full speed and using a tachometer measure the RPM of the blade. The
blade should be rotating between 4,000 and 4,800 RPM. If the blade doesn’t fall with in this range see the Trouble Shooting
section of this manual.
-With the RPM with in the specified range cut through the rail.
-Check that the cut is square. Measure across the base with a tee square and from the base to the ball of the rail, the cut should
be square to within 0.06 inches (1.5 mm) in both directions. If the difference is greater see the Tool Maintenance section of this
manual for adjusting procedures.
6.1.3 Specification of the hydraulic system
The hydraulic unit should ensure a flow of at least 40 lpm (10 gpm) at a pressure of 138 bar (2,002 psi). The pressure must be
limited to 150 bar (2,176 psi). Measurements must be carried out at the minimum operating temperature by 10 °C (50 °F) of the
hydraulic fluid. Warm the hydraulic fluid if necessary.
The temperature of the hydraulic fluid must be limited to 60 °C (140°F).
We recommend the use of the hydraulic units D-23, E-15, G-18, G-21, G-23 or G-31 from PortaCo Inc.
