Sharpening Grass Cutters And Grass Blades; Maintenance Schedule - Husqvarna 129R Operator's Manual

Sharpening grass cutters and grass
blades
WARNING: Always stop the engine
before doing any work on the cutting
attachment. This continues to rotate even
after the throttle has been released.
Ensure that the cutting attachment has
stopped completely and disconnect the
lead from the spark plug before you start
to work on it.
• See the cutting attachment packaging for
correct sharpening instructions.
• Sharpen blades and cutters using a single-cut
flat file.
• Sharpen all edges equally to maintain the
balance of the blade.
WARNING: Always discard a blade that is
bent, twisted, cracked, broken or
damaged in any other way. Never attempt
to straighten a twisted blade so that it can
be reused. Only use original blades of the
specified type.
