Checking for Bent Blades
1. R otate the blades until the ends face forw ard
and bac kw ard ( Figure 49 ). Measure from a
lev el surface to the cutting edg e , position A , of
the blades ( Figure 49 ). Note this dimension.

2. R otate the opposite ends of the blades forw ard.
3. Measure from a lev el surface to the cutting
edg e of the blades at the same position as in
ste p 1 . T he difference betw een the dimensions
obtained in ste ps 1 and 2 m ust not ex ceed
1/8 inc h (3 mm). If this dimension ex ceeds
1/8 inc h (3 mm), the blade is bent and m ust be
re placed. R efer to R emo ving the Blades and

Removing the Blades
T he blades m ust be re placed if a solid object is
hit, if the blade is out of balance , or the blade

blades made b y other man ufacturers ma y result in
non-confor mance with safety standards .
Hold the blade end using a rag or thic kly-padded
glo v e . R emo v e the blade bolt, cur v ed w asher ,
blade stiffener , and blade from the spindle shaft
( Figure 50 ).

Sharpening the Blades
1. Use a file to shar pen the cutting edg e at both
