Maintenance
Checking the Tire Pressure
Service Interval:
Before each use or daily
Vary the tire pressure for all 3 wheels, depending
upon your turf conditions, from a minimum of 83 to a
maximum of 110 kPa (12 psi to 16 psi).
Important:
Ensure that the tire pressure for each
wheel is identical. If the tire pressure for each
wheel is different, the performance of the machine
is affected.
Checking the Torque of the
Wheel Nuts
Service Interval:
After the first 8 hours
Every 200 hours
WARNING
Failure to maintain proper torque of the wheel
nuts could result in personal injury.
Torque the wheel nuts to the specified torque
at the specified intervals.
Wheel-nut torque specification:
108 to 122 N∙m
(80 to 90 ft-lb)
To ensure even distribution, torque the wheel nuts in
the pattern shown in
g274650
