Servicing the Spark Arrester

Inspect the spark arrester every 50 hours for damage, such
as holes in the screen, and for build-up on the screen. If it
is damaged, replace it with a new spark arrester. If it is
dirty, remove it and clean the screen with a wire brush
and/or soak it in solvent.

Cleaning the Cooling Systems

Cleaning the Engine Screen and the Oil
Cooler
Before each use, check and clean engine screen and oil
cooler. Remove any build–up of grass, dirt or other debris

levers and linkage. This will ensure adequate cooling of
the engine and will reduce the possibility of overheating
and mechanical damage.

Greasing and Lubrication

Lubricate the machine when shown on the Check Service
Reference Aid decal (Fig. 35). 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) and turn the
ignition key to off. Move levers to neutral locked
position and apply parking brake. 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.
Greasing the Front Caster Pivots
Lubricate the front caster pivots once a year.
1. Remove hex plug and dust cap. Thread a grease zerk
into hole.
2. Pump grease into zerk until it oozes out around top
bearing.
