WARNING

USE CAUTION WHEN DISMOUNTING LOADERS EQUIPPED WITH OPTIONAL CONTROL VALVE ON TRACTORS EQUIPPED WITH CANOPY. RAISING LOADER SUBFRAME TOO HIGH CAN PINCH HAND BETWEEN CONTROL HAN- DLE AND CANOPY CAUSING INJURY.

G. With tractor at idle speed, roll bucket back until subframe raises up off rear bracket.

H. With tractor at idle speed, carefully activate boom cylinder until cross tube is free of pressure within front bracket channel. It may be necessary to roll bucket back further to maintain sufficient clear- ance between subframe and rear cross tube.

I. Disconnect hydraulic hoses from tractor quick disconnect couplers.

J. Carefully back tractor out of loader.

NOTE

When dismounting the 2427 QT from certain tractor models, additional subframe height is required to clear the front axle. This may be done by rotating the subframe back by extending the boom cylinders once the cross tube is free of the front channel.

K. Reinstall cuffs to loader subframe and place pin in front mounting bracket for storage.

L. Clean all dirt and debris from loader. Dirt will hold moisture and cause rust.

OPERATING INSTRUCTIONS

3-1 GENERAL SAFETY

Only qualified people familiar with this operator’s manual should operate this machine. Operator should wear hard hat, safety glasses, and safety shoes. The operator should read, understand and practice all safety messages shown on the caution, warning and danger decals affixed to the loader to avoid serious injury or death. It is recommended that tractor be equipped with Rollover Protective System (ROPS) and a seat belt be used. Check for ditches, stumps, holes or other obstacles that could upset tractor or damage loader. Always turn off tractor engine, set parking brake, and lower loader to ground before leaving tractor operator’s seat.

3-2 OPERATION

The loader should be operated with the tractor engine running at 1200-1700 rpm. Excessive speeds are dangerous and may cause bucket spillage and unnecessary strain on both the trac- tor and loader.

When operating in temperatures below 30°F (-1°C.), run the tractor engine below 1200 rpm until the oil temperature exceeds 30°F.

A bucket level, indicator rod (Figure 3-1) located on the loader frame can be used to determine bucket angle. Before beginning work, observe the position of indicator rod with bucket flat on ground. Raise boom to several different positions. At each position level bucket, then observe the indicator rod. Once familiar with the indicator rod positions, operation of loader will be easier and more efficient.

The following text and illustrations offer suggested loader and tractor operating techniques.
