Servicing The Fuel Filter; Servicing The Fuel Tank; Servicing The Spark Arrester; Greasing And Lubrication - Toro 74256 Operator's Manual

Servicing the Fuel Filter

Replace the high pressure fuel filter after every 1500
operating hours or more frequently under extremely dusty
or dirty conditions.
Ensure that an Authorized Service Dealer replaces the fuel
filter and any components for the fuel system.
Warning
Fuel system components are under high pressure.
Use of improper components can result in system
failure, gasoline leakage and possible explosion.
Ensure that an Authorized Service Dealer
replace the fuel filter and any components for
the fuel system.
Use only approved fuel lines, hose clamps and
fuel filters for high pressure systems.

Servicing the Fuel Tank

Draining The Fuel Tank
The fuel system is under pressure. Do not attempt to drain
the fuel tank. Ensure that an Authorized Service Dealer
drains the fuel tank and services any components for the
fuel system.

Servicing the Spark Arrester

Inspect the spark arrester every 50 hours for damage, such
as holes in the screen, and for buildup 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. 46). Grease more frequently
when operating conditions are extremely dusty or sandy.
Grease Type: General-purpose grease.
How to Grease
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Clean the grease fittings with a rag. Make sure to
scrape any paint off the front of the fitting(s).
4. Connect a grease gun to the fitting. Pump grease into
the fittings until grease begins to ooze out of the
bearings.
5. 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
the dust cap off until greasing is done. Refer to
Adjusting the Caster Pivot Bearing, page 39.
2. Remove the hex plug. Thread a grease zerk into the
hole.
3. Pump grease into the zerk until it oozes out around the
top bearing.
4. Remove the grease zerk in the hole. Install the hex
plug and cap.
Where to Add Grease
Lubricate the grease fittings as shown on the Check
Service Reference Aid decal (Fig. 46).
