D. FLYWHEEL BRAKE SYSTEM
Tecumseh's Flywheel Brake System provides consumer
safety by shutting down the engine and lawnmower blade
within seconds after the operator releases the engine/
blade control at the handle of the lawnmower.
The Brake Starter Mechanism may be used with either of
two options for starting:
1.
Manual Rope Start
2.
12 Volt Starter System
Each system requires the operator to start unit behind
mower handle in operator zone area. The electric start
system also provides a charging system for battery
recharge when engine is running.
- TO STOP ENGINE (Fig 1). In the stop position the brake
pad (A) is applied to the inside edge of the flywheel; at
the same time the ignition system is grounded out (B).
- TO START THE ENGINE (Fig 2). In order to restart the
engine, the brake control must be applied. This action
pulls the brake pad (A) away from the inside edge of
the flywheel and opens the ignition ground switch (B).
On electric start systems the starter is energized to
start the engine.
On non-electric start systems, recoil starter rope must
be pulled to start engine.
WIRING DIAGRAMS (Electric Start Systems) (Fig 3).
All wiring beyond the connectors on the engine are
supplied by the equipment manufacturer. Check all
terminals and connectors for corrosion and adequate
contact, and all wiring for damage and proper size.
BATTERY
Check battery following the manufacturer's
recommendations. The charging system on the engine
maintains the battery during normal use.
CAUTION:
- Disconnect battery from engine before servicing.
- Before removing flywheel, remove brake pressure from
flywheel to make removal of flywheel easier.
- Compress spring by moving lever toward spark plug
and when hole in lever (A) aligns with hole in bracket
(B), secure lever in this position with alignment tool
670298 (Fig 4). Remove flywheel per normal service
procedure as outlined under IGNITION section of this
manual.
Do not damage brake pad or brake mechanism.
