Cleaning the Cooling System

Service Interval/Specification
Before each use, check and clean engine cooling system.
Remove any build–up of grass, dirt or other debris from
the cylinder and cylinder head cooling fins, air intake
screen on flywheel end, and carburetor–governor levers
and linkage. This will help insure adequate cooling and
correct engine speed and will reduce the possibility of
overheating and mechanical damage to the engine.

Checking the Tire Pressure

Service Interval/Specification
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. 31). Check the tires when they are cold to get the
most accurate pressure reading.
Pressure: 15 psi (103 kPa) rear tires
25–30 psi (172–207 kPa) caster tires
m–4189

Servicing the Brake

Service Interval/Specification
Before each use, check brakes for proper operation.
Always set the parking brake when you stop the machine

power take off (PTO), set the parking brake, and turn
the ignition key to off. Remove the key.

machine forward. Adjustment is required if the wheels
turn and do not lock; refer to Adjusting the Brake,
page 25.
3. Release the brake and press upper control bar very
lightly, approximately 1/2 in. (13 mm), wheels should
rotate freely.
4. If both conditions are met no adjustment is required.
Adjusting the Brake

parking brake does not hold securely, an adjustment is
required.
