Installing the Spark Plug
1. Install the spark plug(s) and metal washer. Make sure
the air gap is set correctly.
2. Tighten the spark plug(s) to 20 ft.-lb. (27 N.m).
3. Push the wire(s) onto the spark plug(s) (Fig. 27).
Greasing and Lubrication
Service Interval/Specification
Grease the wheel bearings every 8 operating hours and the
transmission couplers every 200 operating hours. Grease
more frequently when operating conditions are extremely
dusty or sandy.
Grease Type: General-purpose grease.
How to Grease
1. Disengage the power take off (PTO), set the parking
brake, and turn the ignition key to off. Remove the
key.
2. Clean the grease fittings with a rag. Make sure to
scrape any paint off the front of the fitting(s).
3. Connect a grease gun to the fitting. Pump grease into
the fittings until grease begins to ooze out of the
bearings.
4. Wipe up any excess grease.
Where to Add Grease
1. Lubricate the wheel bearings and front spindles until
grease begins to ooze out of the bearings (Fig. 29).

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.
