Safety System

The machine is equipped with 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 on.

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 not engaged 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.

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.

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 O.E.M. specified tires.

Park Brake

Visually check that no damage is found on the 

lever, links, or switch belonging to the park brake. 

Perform 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.

Cutting Blades

  CAUTION!

  Blades are sharp. Protect 

your hands with gloves and/or wrap blades with 

a heavy cloth when handling.
The sharpening of blades must be 

carried out by an authorized service 

workshop.

For the best mowing effect, it is important that 

the blades are well sharpened and not damaged. 

Replace blades that have been bent or cracked 

when hitting obstacles.
Let the service workshop decide whether a blade 

with large nicks can be repaired/ground or must 

be replaced. Balance the blades after sharpening. 

Check the blade mounts.

Blade Replacement

1. Remove blade bolt by turning it counter 

clockwise.

2. Install new or re-sharpened blade with 

stamped GRASS SIDE facing towards 

ground/grass (down) or THIS SIDE UP facing 

deck and cutter housing.

3. Install and tighten blade bolt securely.
4. Torque blade bolt to  45-55 ft/lbs (61-83 Nm).

IMPORTANT INFORMATION  

The special 

blade bolt is heat treated. Replace it with a 

RedMax bolt if required. Do not a use lower 

grade hardware than specified.

Caster Wheels

Check every 200 hours. Check that wheels rotate 

freely. 

Foam filled tires or solid tires will void the 

warranty.
To replace, remove nut and caster bolt. Pull the 

wheel out of the yoke and take care with the 

spacer. Reinstall in reverse order. Tighten the 

caster bolt and torque to 45 ft-lbs (61 Nm).
