4.2.5. BLADE BRAKE
The blade switch engages the electric clutch when
pulled out to the “ON” position. When the blade
switch is in the “ON” position the cutting blade(s)
are engaged. The blade switch disengages the
electric clutch when the blade switch is pushed in to
the “OFF” position. When the blade switch is in the
“OFF” position the cutting blade(s) are disengaged.
The electric clutch is non-adjustable. The blade(s)
should stop rotation in 5 seconds or less. If the
electric clutch fails to stop the blade(s) rotation in 5
seconds, contact an authorized SNAPPER dealer
to repair or replace.
WARNING
Blades must stop rotating in 5 seconds or less after
blades have been turned off. DO NOT operate
machine until blade brake has been repaired and
functioning properly. Contact your SNAPPER dealer
for assistance.
4.2.6. MOWER DECK ADJUSTMENT (LEVELNESS)
Side-To-Side (48” Decks)
Before making deck leveling adjustments, check
the tire pressure. Add or release air as needed to
bring pressure to 12 P.S.I. in front and 12 P.S.I. in
rear tires. If tires are properly inflated and mowing
is still uneven, adjust side-to-side deck levelness
first as follows:
1. Place SCRAMBLER on a smooth level
surface.
2. Remove footrest/floor pan assembly.
3. Rotate outside blades so tips are pointed to
the sides of deck. See Figure 4.4. Measure the
distance from blade tips to floor. If the
measurement is within 1/8” from side-to-side,
the deck levelness is satisfactory. If the
difference from side-to-side is greater than 1/8”,
continue to Step 4 for adjustment.
