PRE-OPERATION CHECK

LUBRICATION
Lubricate all grease fittings with SAE multipurpose grease.

TRANSMISSION FLUID
Check tractor transmission fluid level. Add fluid if necessary. Refer to the tractor's Operator's Manual for instructions and proper fluid. Repeat this check after purging air from the system. At that time, it will be necessary to add transmission fluid.

• To check tractor transmission fluid level, lower the bucket to the ground and lower the 3 point hitch.

REAR BALLAST

To avoid personal injury:

• For tractor stability and operator's safety, rear ballast should be added to the rear of the tractor in the form of 3•point counter weight and rear wheel ballast. The amount of rear ballast will depend on the application,

Liquid Ballast in Rear Tires
Water and calcium chloride solution provides a safe and economical ballast. Used properly, it will not damage tires, tubes or rims. The addition of calcium chloride is recommended to prevent the water from freezing. Use of this method of weighting the wheels has full approval of the tire manufacturers. See your tire dealer for this service.
Liquid weight per tire (75 Percent filled)

• Do not fill tires with water or solution more than 75% of capacity (to the level of valve stem at 12 o'clock position).
  
  1. Air
  2. Water

NOTE:
When mounting a heavy implement, a liquid in t -s tire may not be required.

• Do not add liquid ballast or any other weigh: the front tires.

TIRE INFLATION
Insure that the tractor tires are properly inflated.
Refer to the tractor's Operator's Manual for optional tires.

Inflation pressure

TEST OPERATION

To avoid personal injury:

• Keep engine speed at low idle during the test operation.
• Escaping hydraulic fluid under pressure can have sufficient force to penetrate skin, causing serious personal injury. Before disconnecting lines, be sure to relieve all pressure.
  Before applying pressure to system, be sure all connections are tight and that lines, tubes and hoses are not damaged. Fluid escaping from a very small hole can be almost invisible. Use a piece of cardboard or wood, rather than hands to search for suspected leaks.
  If injured by escaping fluid, see a doctor at once. Serious infection or allergic reaction will develop if proper medical treatment is not administered immediately.
  

NOTE:

• When the lever is at each corner position marked by asterisk (*), boom and bucket cylinders work at the same time. However, the position marked by cross is not recommended for scooping because of insufficient lift force.
  To begin test operation, slightly move the control lever from the "N" position. Slowly raise the loader boom just enough for the bucket to clear the ground when fully dumped. Slowly work through the dump and roll back cycles.

4 Position bucket control valve type
This loader control valve has two stage dump positions. The first dump position by moving the lever to the right is the "Regular" dump position. It has good power and control for precise dumping. This position should be used when operating another implement with the loader's control valve. The second dump position (to further right) features greater speed for dumping. These two positions are separated by a "Feel" position for your convenience.

OPERATING THE LOADER

The loader should be operated with the tractor engine running from 1700 to 2200 min"(rpm). Excessive speeds are dangerous, and may cause bucket spillage and unnecessary strain on the tractor and loader. When operating in temperatures below -1°C(30°F), run the tractor engine below 1200 rnin'{rpm] until the oil temperature exceeds -1°C(30°F). The following text and illustrations offer suggested loader and tractor operating techniques.

• When operating the loader in rough terrain, remove the mower to avoid damage to the mower.

LIFTING THE LOAD
When lifting the load, keep the bucket positioned to avoid spillage.

To avoid serious personal injury:

• Do not attempt to lift bucket loads in excess of the loader capacity.
• Before raising the bucket to full height, make sure the tractor is on level ground. If not, it may tip over, even if the tractor is not moving.

CARRYING THE LOAD
Position the bucket just below the level of the tractor hood for maximum stability and visibility, whether the bucket is loaded or empty.

Use extreme care when operating the loader on a slope. Keep the bucket as low as possible. This keeps the bucket and tractor center of gravity low and will provide maximum tractor stability.

To avoid serious personal injury:

• Be extra careful when working on inclines.
• When operating on a slope, always operate up and down the slope, never across the slope.
  
  When transporting a load, keep the bucket as low as possible to avoid tipping, in case a wheel drops in a rut.
  

DUMPING THE BUCKET
Lift the bucket just high enough to clear the side of the vehicle. Move the tractor in as close to the side of the vehicle as possible, then dump the bucket.

LOWERING THE BUCKET
After the bucket is dumped, back away from the vehicle while lowering and rolling back the bucket.

OPERATING WITH FLOAT CONTROL

During operation on hard surface, keep the bucket level and put the lift control in the float position to permit the bucket to float on the working surface. If hydraulic down pressure is exerted on the bucket it will wear faster than normal.

The float position will also avoid mixing of surface material with stockpile material. The float position will reduce the chance of surface gouging while removing snow or other material, or when working with a blade.

LOADING FROM A BANK
Choose a forward gear that provides a safe ground speed and power for loading.

To avoid the possibility of serious personal injury:

• Exercise caution when undercutting high banks.
• Dirt slides can be dangerous. Load from as low as possible for maximum efficiency.

NOTE:

• Loader lift and break-away capacity diminish as loading height is increased.
  
  Side cutting is a good technique for cutting down a big pile, Wheel width should not exceed the bucket width for this procedure.
  
  If the pile sides are too high and liable to cause cave in, use the loader to break down the sides until a slot can be cut over the top.
  
  Another method for large dirt piles is to build a ramp to approach to the pile.
  

It is important to keep the bucket level when approaching a bank or pile. This will help avoid gouging the work area.

PEELING AND SCRAPING

Use a slight bucket down angle, travel forward, and hold the lift control forward to start the cut. Make a short cut and break-out cleanly.

With the bucket level, start a cut at the notch approximately 2 in. deep. Hold the depth by feathering the bucket control to adjust the cutting edge up or down. When the front tires enter the notch, adjust the boom cylinder to maintain proper depth.

Make additional passes until the desired depth is reached. During each pass, use only the bucket control while at working depth. This will allow you to concentrate on controlling the bucket angle to maintain a precise cut.

LOADING LOW TRUCKS OR SPREADERS FROM A PILE

For faster loading, minimize the angle of turn and length of run between pile and spreader.

Backgrade occasionally with a loaded bucket to keep the work surface free of ruts and holes. Also, hold the lift control forward so the full weight of the bucket is scraping the ground. Use the heel of the bucket.

BACKFILLING

Approach the pile with the bucket flat.

Poor operating methods will move less dirt and make it more difficult to hold a level grade.

• Do not use the bucket in the dumped position for bulldozing. As shown above, this method will impose severe shock loads on the dump-linkage, the bucket cylinders, and the tractor.

Leave dirt in the bucket because dumping on each pass wastes time.

Operate at right angles to the ditch. Taking as big a bite as the tractor can handle.

Leave dirt which drifts over the side of the bucket for final cleanup.

Pile dirt on the high side for easier backfilling on a slope.

HANDLING LARGE HEAVY OBJECTS

To avoid serious personal injury:

• Handling large, heavy objects can be dangerous due to:
  1. Danger of rolling the tractor over.
  2. Danger of upending the tractor.
  3. Danger of the object rolling or sliding down the loader boom onto the operator.
• If you must perform the above work, protect yourself by:
  1. Do not lift the load higher than necessary to clear the ground when moving.
  2. Add rear ballast to the tractor to compensate for the load.
  3. Do not lift large objects with equipment that does not have an anti-rollback device.
  4. Move slowly and carefully.
  5. Avoid rough terrain.
  6. Keep transport distance as short as possible.

MAINTENANCE

To avoid personal injury:

• Be sure to check and service the tractor on a flat place with the bucket on the ground, engine shut off, the key removed and the parking brake on.

LUBRICATION

1. Lubricate all 10 grease fittings every 10 hours of operation. Also, lubricate joints of control lever linkage every 10 hours. High quality grease designating "extreme pressure" and containing Molybdenum disulfide is recommended. This grease may specify "Moly EP" on its label.
   
2. Daily before operation, check the tractor hydraulic fluid level. If low, add as described in the tractor's Operator's Manual. Also change the filter element and the hydraulic fluid as recommended in the tractor's Operator's Manual.

DAILY CHECKS

1. Check all hardware daily before operation. Tighten hardware to torque values as specified in the "Installation Instructions" and "Tightening Torque Chart".
2. With the engine off and the bucket on the ground, inspect all hoses for cuts or wear. Check for signs of leaks and make sure all fittings are tight.

To avoid personal injury:

• Escaping hydraulic fluid under pressure can have sufficient force to penetrate skin, causing serious personal injury, Before disconnecting lines, be sure to relieve all pressure,
  Before applying pressure to system, be sure all connections are tight and that lines, tubes, and hoses are not damaged. Fluid escaping from a very small hole can be almost invisible. Use a piece of cardboard or wood, rather than hands, to search for suspected leaks.
  If injured by escaping fluid, see a doctor at once. Serious infection or allergic reaction will develop if proper medical treatment is not administered immediately.
