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 34.
2. Remove the hex plug. Thread a grease zerk into hole.
3. Pump grease into zerk until it oozes out around top
bearing.
4. Remove grease zerk in hole. Reinstall hex plug and
cap.

Where to Add Light Oil or Spray
Lubrication
Lubricate the machine in the following areas with spray
type lubricant or light oil. Lubricate every 160 hours.
• Seat switch actuator.
• Brake handle pivot.
• Brake rod bushings.
• Motion control bronze bushings.
Checking the Tire Pressure
Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every
50 operating hours or monthly, whichever occurs first
(Fig. 43). Check the tires when they are cold to get the
most accurate pressure reading.
Pressure: 13 psi (90 kPa) drive wheels and caster wheels.
