MAINTENANCE/SERVICE
SERVICE PROCEDURES
CAUTION: To avoid personal injury, before servicing machine or opening drive covers:
1. Fully lower header and reel. If it is necessary to service in the raised position, first engage header
lift cylinder stops and reel props.
2. Disengage header drive clutch.
3. Stop engine and remove key.
4. Engage park brake.
5. Wait for all moving parts to stop.
6. Park on level surface when possible. Block wheels securely. Follow all recommendations in your
Combine Operator’s Manual.
7. Wear close-fitting clothing and cover long hair. Never wear dangling items such as scarves or
bracelets.
8. Wear protective shoes with slip resistant soles, a hard hat, protective glasses or goggles and heavy
gloves.
9. Be prepared if an accident should occur. Know where the first aid kit and fire extinguisher are
located and how to use them.
10. Keep the service area clean and dry. Wet or oily floors are slippery. Wet spots can be dangerous
when working with electrical equipment. Be sure all electrical outlets and tools are properly
grounded.
11. Use adequate light for the job at hand.
12. Replace all shields removed or opened for service.
13. Use only service and repair parts made or approved by the equipment manufacturer. Substituted
parts may not meet strength, design or safety requirements.
14. Keep the machine clean. Never use gasoline, naphtha or any volatile material for cleaning
purposes. These materials may be toxic and/or flammable.
RECOMMENDED LUBRICANTS
GREASE
Use an SAE Multi-Purpose High Temperature Grease with Extreme Pressure (EP2) Performance and
containing a maximum of 1% moly (molybdenum disulphide).
For driveline slip-joints only, increased moly content (up to 10%) is recommended. IMPORTANT: Do not
use this higher moly content grease on bearings, as it may cause excessive wear in high speed applications.
HYDRAULIC OIL
Use single grade trans-hydraulic oil. If an oil brand from the recommended list is not available, use 15W40
engine oil. If 15W40 oil is substituted, drain adapter reservoir first. Do not mix engine oil with trans-hydraulic oil.
The following oil company and equipment manufacturer brand names are recommended:
Petro Canada Duratran
Case IH Hy-Tran Plus®
John Deere Quatrol® J20C
Agco Power Fluid 821XL
GEARBOX OIL
SAE 85W-140 gear lubricant (API Service Classification GL-5)
CAPACITIES

STORING AND HANDLING LUBRICANTS
Your machine can operate at top efficiency only if clean lubricants are used. Contaminant in lubricants is the
most likely cause of bearing and hydraulic system failure. Use clean containers to handle all lubricants. Store
lubricants in an area protected from dust, moisture and other contaminants. Keep hydraulic couplers and
connectors clean.
