Servicing the Cutting
Blades
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
keep extra blades on hand.
Blade Safety
A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death. Trying to
repair a damaged blade may result in discontinued
safety certification of the product.
•
Inspect the blades periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
Before Inspecting or Servicing the
Blades
1. Park the machine on a level surface, disengage
the blade-control switch, and engage the parking
brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
