MAINTENANCE

Safety System

The machine has a safety system that prevents
starting or driving under the following conditions.
The engine can only be started when:
• the mower deck is disengaged.
• the steering controls are in the outer, locked
neutral position.
• the park brake is engaged.
IMPORTANT INFORMATION To be able to
drive, the driver must sit in the seat and release
the park brake before the steering controls can
be moved into the neutral position, otherwise
the engine will stop.
Make daily inspections to ensure that the safety
system works by attempting to start the engine
when one of the conditions is not met. Change
the conditions and try again.
If the machine starts when one of these
conditions is not met, turn the machine off and
repair the safety system before using the machine
again.
Make sure the engine stops when the park brake
is released and the operator leaves the seated
position.
Check that the engine stops if the mower blades
are engaged and the driver temporarily moves off
the driver's seat.

Park Brake

Visually check that no damage is found on the
lever, links, or switch belonging to the park
brake. Do a standstill test and check that there
is sufficient braking. For park brake adjustments,
contact the RedMax service workshop.
WARNING! Faulty adjustment will result
in reduced braking and can cause an accident.

Tire Pressures

All tires must be at 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION DO NOT add
a tire liner or foam fill material to the tires.
Excessive loads created by foam filled tires will
cause premature failures.
Only use tires specified by RedMax.

severe cracking and large nicks. The belts are not
adjustable. Replace the belts if they begin to slip
from wear.
NOTE: The belt will show some small cracks in
normal operation.
Deck Belt
Deck Belt Removal
Park on a level surface. Engage park brake.
Lower the deck into the lowest cutting position.
1. Remove foot plate and belt shields.
2. Remove dirt or grass that has accumulated
around the cutter housings and the deck
surface.
3. Using a ratchet or a breaker bar and 9/16"
socket in the square opening in the idler arm,
shift the arm counter clockwise to release the
tension on the belt.
4. Carefully lift the belt over the top of the cutter
housing pulleys.
5. Remove the belt from around the electric
clutch on the engine shaft.
Deck Belt Installation
NOTE: For ease in installing the deck belt, refer to
the routing decal on the cutting deck.
