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. 43). 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

Cleaning the Cooling System
Service Interval/Specification
Before each use, check and clean engine cooling system.
Remove any buildup 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.

Machine
Service Interval/Specification
Grease the areas shown at the intervals given in the Where
to Add Grease section below. Grease more frequently when
operating conditions are extremely dusty or sandy.
Grease with No. 2 general-purpose lithium-base or
molybdenum-base grease.
Applying the Grease
1.
Disengage the PTO and set the parking brake.
2.
Stop the engine and wait for all moving parts to stop
before leaving the operating position.
3.
Clean the grease fittings with a rag and scrape any paint
from the front of the fittings.
4.
Connect a grease gun to the fitting and pump grease
into the fittings until grease begins to ooze out of the
bearings.
5.
Wipe up any excess grease.
Locating Where to Apply Grease
1.
Lubricate the caster wheel bearings and front spindles
every 8 operating hours (Fig. 44).
