Greasing And Lubrication; Greasing The Bearings - Toro 74259 Operator's Manual

Cleaning the Engine Fins
Every 100 hours clean the engine cylinder and cylinder
head cooling fins. Also clean around carburetor, governor
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. 45). 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 the dust cap and adjust the caster pivots. Keep
dust cap off until greasing is done. Refer to Adjusting
the Caster Pivot Bearing, page 42.
2. Remove hex plug and dust cap. Thread a grease zerk
into hole.
