BRAKES AND TIRES
SERVICE BRAKES
The mechanical service brakes are located on the
front wheels. The brakes are operated by the foot
brake pedal and connecting cables.
Check the brake adjustment every 200 hours of
operation. The brake pedal should not travel more
than 25 mm (1 in) to fully engage the brakes.
PARKING BRAKE
The parking brake is set with the parking brake
lever that activates the service brakes.
Adjust the parking brake whenever it becomes
very easy to set the parking brake, when the
machine rolls after setting the parking brake, and
every 200 hours of operation. The parking brake
may be tightened by turning the knurled knob on
the end of the parking brake clockwise.
TIRES
The standard front machine tires are solid. The
standard rear machine tire is pneumatic.
Check the rear tire pressure every 100 hours of
operation. The proper tire air pressure is
790 + 35 kPa (115 + 5 psi).
REAR WHEEL
Torque the rear wheel nuts in a star pattern twice
to 142 to 157 Nm (105 to 115 ft lb) after the first
50-hours of operation, and every 800 hours there
after.
