NEVER RUN ENGINE INDOORS OR IN ENCLOSED,
POORLY VENTILATED AREAS. ENGINE EXHAUST
CONTAINS CARBON MONOXIDE, AN ODORLESS
KEEP HANDS, FEET, HAIR, AND LOOSE CLOTHING
AWAY FROM ANY MOVING PARTS ON ENGINE AND
WARNING - TEMPERATURE OF MUFFLER AND NEAR
BY AREAS MAY EXCEED 150°F (65°C). AVOID THESE
1. Make sure workpiece, cutter and shoe surfaces are
2. Place locator template on rail head.
3. Align drill on locator with the Hole Location Template.
4. Clamp drill to rail and insure proper 10 point contact.
5. Turn on coolant (pump to pressurize system).
6. Move choke lever to “FULL CHOKE”. If restarting a
warm engine after a short shutdown, move choke lever
7. Turn motor on/off switch to “ON” position.
8. Move throttle to idle position.
9. Grasp starter handle and pull rope out, slowly, until it
meets resistance. Let rope rewind slowly. Then pull
rope with a rapid full arm stroke. Let rope return to
10. Repeat step #9 until engine fi res.
11. Move throttle to run position.
12. Manually feed cutter very gently to start cutting.
13. Once all teeth are cutting aggressively, feed tool
through workpiece at an even rate. Do not over-
load unit to induce an arbor stalling situation. Certain
rail compositions workharden easily. Do not pause
during cut nor release feed pressure if changing hand
grip on feed handle. This will result in premature
cutter wear and drilling problems while in the cut.
14. Move feed handle to retract arbor and cutter. Slug
should eject from spring loaded pilot pin pressure.
15. Move throttle to idle position.
16. At the end of the cut, move ignition switch on engine
to “STOP” or “OFF” position.
17. Loosen clamp and remove drill to clean chips from
around cutter. Drill cycle is complete and you are
ready to go on to the next hole. Shutting off coolant
after use is suggested, if use is intermittent.
If Slug Has Not Fallen Free
wire from spark plug and shut off coolant supply. Use a
screwdriver to carefully fl ip slug by inserting it between
slug fl ange and cutter gullet. It generally will remove
easily while discharging a squirt of coolant. Avoid
prying with force, damage to the cutter and cutting
WHEN EQUIPMENT WILL NOT BE USED FOR
EXTENDED PERIODS, DISCONNECT SPARK PLUG
WIRE FROM SPARK PLUG AND KEEP IT AWAY
NEVER STORE ENGINE WITH FUEL IN TANK
INDOORS OR IN ENCLOSED, POORLY
VENTILATED AREAS, WHERE FUEL FUMES MAY
REACH AN OPEN FLAME, SPARK, OR PILOT
LIGHT AS ON A FURNACE, WATER HEATER,
CLOTHES DRYER OR OTHER GAS APPLIANCE.
Important Notice
1. Make sure cutter is properly installed.
2. The #1 cause of premature cutter failure is improper clamping. (see page 7 for
3. The # 2 cause of premature cutter failure is improper feed, usually feeding too slow.
4. Always use caution when contacting the rail with the cutting tool. Allow the cutter to
completely enter the rail before applying full feed pressure.
GAS MUST BE SHUT OFF BEFORE TRANSPORTING DRILL.
