Tire Pressure Service
Maintain the air pressure in the front and rear tires as
specified. Check the pressure at the valve stem after every
50 operating hours or monthly, whichever occurs first
(Fig. 24). Check the tires when they are cold to get the most
accurate pressure reading.
Pressure: 103 kPa (15 psi) front and rear

Cleaning the Cooling System
Before each use, remove grass clippings, dirt, and grime
from the entire machine, muffler, and engine air intake
screen. Every 100 operating hours clean dirt and chaff from
the engine cylinder head fins and blower housing. This will
help ensure adequate cooling and reduce the possibility of
overheating and mechanical damage to the engine.
1. Open hood and pull the spark plug wire(s) off.
2. To avoid overheating and possible engine damage
clean, grass, dust, dirt, and oil from the outside of the
engine, air intake screen, and muffler.
3. To clean the cylinder head fins, remove the engine from
the chassis and remove the cooling shrouds. Make sure
that the cooling shrouds are installed before operating
the engine.
Adjusting the Belts
If belt slippage occurs, the idler pulleys must be adjusted to
increase the belt tension.
1. Disengage the power take off (PTO), set the parking
brake, stop the engine, and remove the key.
2. Raise the seat.
3. Measure the distance from the bottom of the spacer on
the pulley mounting screw to the bottom of the slot in
the idler adjustment link. The distance should be 1/4 in.
(6 mm) or less (Fig. 25).
4. To adjust, remove the hairpin cotter and washer
securing the tension bracket to the mounting pin
(Fig. 25).
5. Slide the tension bracket off of the mounting pin.
Adjust and select a new hole until the bottom of the
spacer is within 1/4 in. (6 mm) from the bottom of the
slot (Fig. 25).
6. Secure the tension bracket with the washer and hairpin
cotter (Fig. 25).
