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.
