RAIL GRINDING PROCEDURE

It is recommended that before grinding, the rail surface be wiped clean with a cloth saturated with mineral spirits, followed by a
wipe with a clean dry cloth. Surface contaminants such as rust, grease, oil, and water condensation will affect the integrity of a
CADWELD

bond. Discard soiled rags etc. in an approved manner.

Reference the pictures that follow:

1. Stance: Take the proper stance in front of the area to be ground with the

grinder idling. Rest right arm on knee while in squatting position. Lift with your
legs, not your back.

2. Tool Rest Adjustment: This grinder can be used for both head grinding and

web grinding. Adjust the tool rest so that the grinding wheel is positioned at
the correct height.

Wheel Position:

Head Grinding Wheel should be at the center of the head of the rail,
above the splice plate.

Web Grinding Wheel should be at the Neutral Axis of the rail.

3. Wheel Guard Adjustment: If desired, you may adjust the orientation of the

wheel guard by loosening the spring collar bolt and rotating the guard to the
desired position. Retighten bolt before grinding.

4. Grip: Grasp the throttle control handle with your left hand while gripping

the auxiliary foam handle with your right hand.

5. Use the tool rest to support the weight of the grinder. NEVER REST THE GRINDER

ON THE CLUTCH GUARD. Accelerate the engine to full throttle just before wheel
touches area to be ground.

6. Begin grinding with the wheel against the rail moving with a side-to-side motion

until bright base metal is shown.

7. Allow wheel to do grinding for you. Exert only slight pressure.

8. Release the throttle trigger as soon as the wheel loses contact with the rail,

allowing the engine to idle.

Note! If you run the grinder at full throttle without a grinding load, unnecessary wear
can occur to the belt, bearings and engine.
