8.Appendix
8.1. LIFT CYLINDER HYDRAULICS
The MK 91'/111' auger is elevated with 2, specially designed, single-acting
hydraulic cylinders and cables.The following table lists the psi required to raise
specific auger sizes (as determined by Westfield testing).
These tests used a hydraulic pressure gauge (4000 psi maximum rating) and are
solely intended to be used as a guide. The psi requirements for specific augers
may vary slightly. Should your auger require a significantly higher psi to raise,
contact either your dealer or Westfield Industries.
The approximate quantity of hydraulic fluid required to raise auger is 4 liters.
8.2. HOW TO CHARGE THE LIFT SYSTEM
Important: The hydraulic cylinders are shipped without oil and must be charged with oil
before auger is put into operation.
The cylinder will require about 19 L (5 US gallons). Check your tractor’s
operation manual for correct oil type and specifications.
Before charging cylinders, ensure that:
• Tractor is correctly hooked up.
• Hydraulic hoses are connected.
• Shut-off valve is open.
• Auger is parked on level ground.
Note: Do not raise auger in high winds.
1. Start with the tractor's hydraulic oil level in a normal operating range.
2. Add about 4 L (1 US gallon) to the tractor's hydraulic oil reservoir.
3. Start tractor, then raise auger until the lift-assist is fully extended and track
shoe has moved about 1’ from trackstop.
4. With tractor still running, lower auger to full down position.
5. Repeat steps 2. 3. and 4. until about 19 L (5 US gallons) have been added
and tractor hydraulic oil level in the reservoir remains within the operating
range.
