Servicing The Spark Arrester; Greasing And Lubrication; Greasing The Bearings - Toro 74216 Operator's Manual

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.

Greasing and Lubrication

Lubricate the machine when shown on the CHECK
SERVICE REFERENCE AID decal (Fig. 48). 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" to stop the engine. 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.
Grease Front Castor Pivots
Lubricate the front castor pivots once a year.
1. Remove hex plug and cap. Thread a grease zerk into
hole.
2. Pump grease into zerk until it oozes out around top
bearing.
3. Remove grease zero in hole. Reinstall hex plug and
cap.
