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.

Cleaning the Cooling Systems
Before each use, check and clean cooling screen. Remove
any build–up of grass, dirt or other debris from the oil
cooler screen and engine air intake. Every 100 hours clean
oil cooler, engine cylinder and cylinder head cooling fins.
Also clean around carburetor, governor levers and linkage.
This will help insure adequate cooling to hydraulic
pumps, motors and engine and will reduce the possibility
of overheating and mechanical damage.
