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.
