Snapper 21500 User Manual

When the blade’s cutting edges have become dull
(while in otherwise good condition), sharpen on a
grinding wheel at an angle of 22 to 28 degrees.
The cutting surface (on each end) should extend in¬
ward about 3-1/2"' from the tip. After sharpening,
check the blade for balance - a blade "out of
balance"will cause excessive vibration. Re-balance
as required.
Re-install the blade with the components in proper
sequence as shown in FIG. 10. _
NOTE
SHARPEN THE SPECIAL RECYCLING BLADE
(NINJA) ON A BENCH GRINDER AT AN
ANGLE OF 22 TO 28 DEGREES. _
DO NOT substitute any components! Make sure the
flange on each side of blade (at the mounting hole)
fits over the edge of the blade drive hub (A). Tighten
the blade retaining capscrew (B) to 30 FOOT
POUNDS TORQUE. _
CLUTCH LINKAGE (SELF-PROPELLED) '
The vinyl (tube type) cover (A) should always conceal
outer (B) and inner (C) clutch cable springs. The spr¬
ing combination connects the clutch cable to the
clutch idler components (refer to FIG. 11). The cover
(A) prevents accummulation of dirt on the springs
and eliminates the possibility of their wearing a hole
through a grass bag.
ADJUSTMENT: Should excessive pressure be re¬
quired to hold the WHEEL DRIVE CONTROL lever
(19) against the UPPER HANDLE (18), spring ad¬
justing is needed! Refer to FIG. 11.
When properly adjusted, there should be 1/16" to
1/8" clearance between the INSIDE of spring (B)
hook and the INSIDE of the clutch cable "eye". Stop
the engine and release the WHEEL DRIVE CON¬
TROL lever/and pull back cover (A) to check
clearance.
To adjust, unhook springs from cable (at "eye") and
rotate springs in opposite directions and re-hook to
cable and check clearance. Repeat procedure if
needed.
FIG. 10 - BLADE RETENTION DETAIL
If the WHEEL DRIVE CONTROL lever fails to "snap"
back when released, check for binding at the cable
holding clip located on side of handle - it should be
about 5" below the upper handle and permit the
cable to slide freely. Refer to FIG. 11-A.
