Priming the Fuel System
The primer pump is the gold metal button on top of the
fuel filter Fig. 49.
To bleed air from the fuel system, push down on the
primer pump until resistance becomes firm. This should
take about 10–15 pushes on the primer pump.

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.
Greasing and Lubrication
Lubricate the machine when shown on the Check Service
Reference Aid decal (Fig. 50). 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 stop the
engine. Move the levers to the neutral locked position
and apply the parking brake. Remove the key.
2. Clean the grease fittings with a rag. Make sure to
scrape any paint off of 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.
