SRM-266 MAINTENANCE

When the wear indicators located

at the bottom of the Speed-

Feed® head are worn smooth, or

if holes appear, replacement of

the cover or the entire Speed-

Feed® head is required.

Sharpening Metal Blades

Several styles of metal blades are

approved for use on the Brush

Cutter. The 8-tooth blade can be

sharpened during normal

maintenance. The clearing blade and

80 tooth blade require professional

service.

Before sharpening, CLOSELY

inspect blade for cracks (look at the

bottom of each tooth and the center

mounting hole closely), missing teeth

and bending. If ANY of these

problems are discovered, replace the

blade.

When sharpening a blade, always remove the same amount of materials from

each tooth to maintain balance. A blade that is not balanced will cause unsafe

handling due to vibration and can result in blade failure.

1. File each tooth at a 30 degree

angle a specific number of

times, e.g., 4 strokes per tooth.

Work your way around the blade

until all teeth are sharp.

2. DO NOT file the ‘gullet’ (radius)

of the tooth with the flat file. The

radius must remain. A sharp

corner will lead to a crack and

blade failure.
