[2] SAFETY PROCEDURES
READ BEFORE USING THE MACHINE
•ALWAYS WEAR SAFETY GOGGLES AND EAR DEFENDERS WHEN
OPERATING THE MACHINE.
•Ensure motor is switched off when changing cutters, working on the machine, or
removing swarf.
•Always ensure the cutter is securely fastened.
•Remove tie, rings, watches and loose adornments, which might entangle with the rotating
machinery.
•Should the cutter become fast in the workpiece, switch off the motor immediately to
prevent personal injury. Do not attempt to free the cutter by starting and stopping the
motor.
•If the machine is accidentally dropped, always thoroughly examine the machine for signs
of damage and check that it functions correctly before trying to cut a hole.
•Regularly inspect the machine and check that nuts and screws are tight.
•Before fuelling the tank, read section 5 (fuelling)
•Observe local and national Health & Safety requirements before operating the machine.
•Never leave the machine lying on its side. The motor sump oil may be lost at an
inclination greater than 20˚from the vertical. If this may have happened, check the sump
oil level before starting the engine.
•Always wear approved eye and ear protection when the equipment is in operation.
Failure to do so may result in personal injury.
•On completion of the cut, a slug will be ejected. DO NOT operate the machine if the
ejected slug may cause injury.

[3] ROTABROACH CUTTING FLUID
•Rotabroach cutting fluid has been specifically formulated to significantly enhance the
performance and life of the cutting tool, and improve the quality and surface finish of the
hole.
•Avialable in
1 litre (RD208)
5 litre (RD229)
25 litre (RD220)
[4] COOLANT INDUCEMENT
•Constituent items:
Coolant bottle and hose assembly RY2001

[5] FUELLING
Warning
Petrol is an extremely flammable fuel.
Use extreme caution when handling petrol or fuel mix.
Do not smoke or bring any fire or flame near the fuel.
Ensure the fuel mix does not spill on to hot engine.
FUELLING INSTRUCTIONS
•Fuel your machine in a well-ventilated area, outdoors only.
•Avoid direct contact with the skin and avoid inhaling fuel vapour
•Always shut off the engine and allow it to cool before refuelling.
•Before fuelling, clean the filler cap and the area around it to ensure that no dirt falls into
the tank.
•Petrol vapour pressure may build up inside the gas tank. In order to reduce the risk of
burns or other personal injury from escaping gas vapour and fumes, remove the gas cap
carefully so as to allow any pressure build-up in the tank to release slowly. Never
remove the fuel filler cap whilst the engine is running,
FUEL
•It is recommended that you always use unleaded petrol with a minimum octane number of
90 ROZ(USA)/Canada: pump octane min. 87.
•Inferior quality petrol may damage the engine, sealing rings, fuel lines or fuel tank.

[6] MOTOR OPERATING INSTRUCTIONS
STARTING
•Observe safety precautions (see Section 2 – Safety Procedures)
•Ensure that the sump oil level is to the correct level.
•Ensure the machine is clamped firmly in position on the rail.
•Ensure on/off switch (RD4748) is set to 1.
•Unscrew petrol tank vent screw.
•If the motor is cold, position cold start indicator to 1 o 1.

•Rotate the fuel cut off valve to the horizontal position.
•Position the cutter feed handle to the forward position.
•Repeatedly pull the engine start cord with a quick, progressive movement until the engine
starts, then release the cord handle.
•When the engine has reached it’s operating temperature, the cold start lever can be moved
from the cold start position.
•Moving the cutter feed handle anti-clockwise will increase the engine speed and feed the
cutter into the rail.

[7] MACHINE OPERATING INSTRUCTIONS
•Keep the inside of the cutter clear of swarf. It restricts the operating depth of the cutter.
•Pressurise the coolant dispenser by pumping the handle until the relief valve extends and
then give a further 5 to 10 pumps of the handle.
•With the pressurised cutting fluid dispenser connected to the coolant feed tube, coolant is
“metered” out by the pilot and is applied directly to the cutting edge.
•To ensure cutting fluid is being correctly metered, depress the pilot by slowly moving the
cutter to touch the rail. Regulate the flow by adjusting the needle valve RD4217.
•As the cutter approaches the rail, the automatic throttle will increase the engine speed to
ensure maximum speed before cutting the hole. Once drilling is complete immediately
fully retract the cutter, this will return the machine to idle speed. DO NOT ALLOW
THE MACHINE TO RUN AT FULL SPEED IF NOT DRILLING.
•When commencing to cut a hole apply light pressure until the cutter is introduced into the
work surface. Pressure can then be increased slightly whilst cutting the hole. Excessive
pressure is undesirable when using the Rotabroach system, it does not necessarily
increase the speed of penetration and it may damage the cutter, greatly reducing its life.
•Cutter breakage is usually caused by insecure clamping.

[8] ROTABROACH CUTTERS FOR RAIL DRILLING MACHINES
All cutters have a 3/4" dia. shank.
ALWAYS ENSURE THAT THE MACHINE IS SWITCHED OFF
Take the chosen cutter and insert into its shank the appropriate pilot. Place the assembly,
correctly aligning the drive flats, into the arbor bore and securely fasten the socket screws
with the hexagon key.
