CARE AND MAINTENANCE
HYDROSTATIC TRANSMISSION OIL AND FILTER SERVICE
SERVICE INTERVALS: 1. Initial oil and filter service - 50 hours.
2. Every 250 hours thereafter.
OIL REQUIREMENTS: Any high quality engine oil with an API classification
of SG/CD is recommended.
RECOMMENDED OIL WEIGHT: Normal operation temperatures - 20 W 50
Cold climate usage - 10 W 40
Another alternative that will provide excellent all
climate performance and extended time between oil
changes is a 15 W 50 synthetic engine oil.
OIL FILTER: P/N 7252- IMPORTANT
The oil filter is a special
design for use on "vacuum
or suction" oil flow systems.
DO NOT: Use automotive engine oil
filters. These filters require
a "pressure" to allow oil
flow. Usage will result in an
"air-lock" condition with
possible damage.
